Backwashing reverses water flow to remove contaminant buildup in your sand filter. And it’s a simple process of connecting a backwash hose to your filter and using the backwash setting to send water from your pool through your filter and out the waste port. In general, you should backwash your filter if the filter gauge pressure reads above 10 PSI or you notice a weak flow of water out of your return jets. But you’ll need to backwash more often if you have an algae-infested pool or you’ve just used a pool flocculant.

Check out the video tutorial below or keep reading for a step-by-step guide on how to backwash your sand filter.

What is Backwashing?

As water regularly passes through your sand filter, it leaves behind dirt, debris, and other contaminants in the filter medium or sand.  Over time as water flows through, that filter medium will become clogged. And that can reduce your filter’s effectiveness.

When you backwash, you’re sending water backward through your filter and out your filter’s waste port or drain port. This forces all the debris caught in the filter medium to dislodge and clear out.

You’ll need to regularly backwash a sand filter or diatomaceous earth or D.E. filter, but you do not need to backwash if you have a cartridge filter.

When to Backwash a Sand Filter

In general, you should backwash your filter when your filter pressure rises 10 PSI above normal running pressure or if you notice poor flow from your return jet.

Take note of the pressure gauge reading when you first set up your filter or right after you backwash. That’s your normal operating filter pressure. When the pressure gauge reads 10 psi or more above normal, it’s time to backwash.

Just make sure you don’t want to backwash too frequently. When there’s a little build-up in your filter, it actually helps capture tinier bits of debris. A clean filter is good. A slightly dirty filter is better. But a clogged filter is bad and needs backwashing.

You’ll also need to backwash if you’ve recently filtered out a lot of debris, contaminants, or dirty water. If your filter is running after cleaning up an algae bloom or after a heavy storm, you’ll need to backwash. It’s also a good idea to backwash your filter after you’ve vacuumed your pool or if you’ve used a pool flocculant.

How Do You Know if Your Sand Filter is Clogged?

Here are a few ways to tell if your sand filter is too dirty and it’s time to backwash.

Filter Pressure is 10 PSI Above Normal

If you notice that your sand filter’s pressure gauge reads 10 PSI or more over its baseline, it’s time to backwash. You can find your filter’s normal operating pressure by looking at your pressure gauge after backwashing.

Low Water Flow from Return Jets

If you notice low water flow out of your return jets, it’s a sign you need to backwash. Generally, when the flow rate drops, you’ll see an increase in PSI, and may even see cloudy water.

Cloudy Pool Water

If your water isn’t as clear as it usually is, or you can see visible debris in the water that the filter should have removed, that can be an indication your sand filter isn’t filtering effectively.

After Heavy Rain or Debris Load

If a large amount of dirt or debris gets into your pool water, like after a big rain storm, you’ll need to backwash after clearing out the debris with a skimmer net and a manual vacuum or after shocking your pool water.

How to Backwash Your Sand Filter Step By Step

The backwashing process is easy, but following the right steps in the right order will help you avoid filter damage and get your filter system as clean as possible.

And before you run your filter, make sure your pool’s water level is halfway up the skimmer or higher, since you’ll be losing pool water in the process. Finally, to backwash, the only extra supply you’ll need is a backwash hose.

1. Turn the filter system off. Then remove the skimmer basket, especially if it’s full of debris.
2. Attach the backwash hose to filter waste port. This is also known as the waste line or backwash port. Your backwash hose will have a lot of water flowing out of it, so be sure the end is placed in an appropriate spot.
3. Turn your multiport valve to the Backwash position. Then turn the filter system back on. Water should be flowing out of the backwash port and through the hose.
4. Let the water run for about one minute, or until the water runs clear. Check the water clarity coming out of the end of your backwash hose or check your filter sight glass.
5. Turn your filter system off and turn the filter valve from Backwash to Rinse. This will help remove sand from your lines before the water flows back into your pool. If you don’t have a Rinse setting, use the Waste setting.
6. Turn your filter system back on and rinse the filter for about 30 seconds.
7. Turn the filter system off and turn the multiport valve to the Filter setting. You can now turn the system back on and run it regularly.
8. Refill, test, and balance your pool water as necessary. The backwash process removes water from your pool and you’ll need to rebalance your chemicals.

Note: Make sure your filter is off before turning your filter valve into a new position. Moving the filter valve handle while the filter is on or while water is flowing can damage the multiport valve handle gasket.

What if Backwashing Didn’t Work?

If you’re still experiencing signs of a dirty sand filter, it’s time to re-evaluate:

• Check all your pool chemical levels to make sure something else isn’t causing cloudy water, like your pH or calcium hardness.
• Check for damage to your sand filter. If your sand filter is very old or very cheap, you could have a cracked lateral inside the sand filter tank. Or your need your entire filter may need replacing.
• Check the rest of your pool plumbing system for clogs or leaks. If you have low return jet pressure, you could have a leak or clog in the pressure side of your pool.

If you’re still experiencing pressure problems, be sure to check out our Pool Filter Pressure Troubleshooting Guide.

How Often Do I Need to Change the Pool Filter Sand?

You will need to change the pool filter sand every three to five years. And you’ll know it’s time to change the sand in your filter if the water is dirtier than usual and the sand is clumped together or greasy.

Laterals are the bars of star-shaped section at the bottom of the sand filter. With time, regular wear and tear and pressure from the sand may cause them to break. And if you have a broken lateral, your filter’s efficiency will suffer.

Frequently Asked Questions About How to Backwash a Sand Filter

Need more help backwashing a sand filter? Here are some common questions and answers.

How often should you backwash your sand filter?

You should backwash a pool filter when you notice the filter pressure running 10 PSI above normal, cloudy water or if you notice low water flow coming from your return jets. For more information, check out our video on How Often Should You Backwash a Pool Filter.

What’s the difference between backwash and rinse?

Backwash sends water in the opposite direction through the filter. Rinse sends water through the same in the same direction as normal filtration. The Rinse setting clears dirt from the clean side of the sand before sending it back to the swimming pool.

Do you backwash or rinse a sand filter first?

Backwash the filter, then rinse the filter afterward to prevent blowback into the pool. The backwash setting flushes contaminants built up in the sand. And the rinse setting resets the sand to its original position for the best filtration.

How long do I rinse my sand filter after backwashing?

Rinse your filter for at least 30 seconds after backwashing. Otherwise, you could risk blowing sand back into your pool through your return jets.

Does backwashing remove water from the pool?

Yes, a certain amount of water loss is unavoidable when you backwash. But you can reduce the amount of water you lose by closely monitoring the clarity of the water as it comes out of the waste line and stopping the process as soon as it runs clear.

How do I backwash my above ground pool sand filter?

Your above ground sand filter should have the same settings as any other sand filter, including backwash and rinse. If you don’t have these settings or you don’t have a waste port, you may have a cartridge filter instead. If you have a smaller filter like an Intex sand filter, you may want to do your backwashing in rounds. Backwash for one minute and then rinse for one minute. Repeat this cycle for 3 rounds to avoid blowing anything back into the pool.

Wondering whether a D.E. filter is worth it for your pool? Keep reading for a complete guide on how these filters work and what to look for when buying the best D.E. filter for your swimming pool.

How Does a D.E. Filter Work?

A D.E. filter uses diatomaceous earth as the filter media. What is diatomaceous earth? It’s the fossilized remains of diatoms, a kind of aquatic creature with a skeleton high in silica. D.E. powder is sold at most pool and hardware retailers, so it’s easy to find – and it’s affordable, too.

When D.E. powder is added to the filter, it attaches to the grid or fingers inside the filter, creating a D.E. “cake.” And this cake, along with the filter grids inside, helps filter out fine particles in your pool water. This makes a D.E. filter the most powerful filtration system, compared to sand or cartridge filters.

Over time, the filter element will get dirty and contaminants will build up in the D.E. powder. And unfortunately, cleaning a D.E. filter requires multiple steps compared to other types.

To clean a D.E. filter, you’ll need to remove the D.E. grid and spray it down with a garden hose or soak it in muriatic acid to remove oil, minerals, and dirt.

You’ll also need to regularly backwash the D.E. filter to help remove the buildup that’s accumulated inside. That means reversing the flow of water inside the filter, which loosens the collected dirt and debris to leave the tank. That water is then sent out of your pool using the filter’s waste port.

Finally, when you’re replacing your grids or backwashing the filter, you’ll need to add more D.E. powder. This is added directly through the skimmer line where it then travels into your filter.

D.E. FIlters vs. Sand Filters: Which One is Better?

Both D.E. filters and sand filters use powder or sand to capture particles to clean your water. And whether you use a D.E. or sand filter system, you’ll need to backwash each one regularly to help remove the dirt, debris, and dirty water.

But when compared to a sand filter, D.E. filters provide much better filtration of smaller contaminants. A sand filter will filter particles ranging from 20 to 40 microns in size, whereas a D.E. filter can handle particles as small as 1 to 6 microns. Things in your pool water like deodorant and other cosmetic products can be as small as 6 microns. And skin flakes can range from 0.5 to 10 microns. So while these might pass through a sand filter and end up back in your pool, they’ll be captured by a D.E. filter.

However, while a D.E. filter will take care of smaller particles, you can expect more maintenance, more cleaning, and a higher upfront cost.

While you’ll only need to backwash your sand filter for regular maintenance, a D.E. filter is more involved. D.E. filter grids require cleaning, which means taking apart the filter and spraying down your grids with water or soaking them in muriatic acid. And after each filter backwash, you’ll need to add more D.E. powder.

Finally, sand filters are one of the most common types of pool filters. That also means the initial investment is much more affordable than a D.E. filter. However, you’ll need to replace the sand or D.E. powder in both types of filters every 4 to 5 years.

Overall, D.E. filters are more powerful than sand filters, giving your cleaner pool water. But remember that D.E. filters require more maintenance and ongoing work and tend to be more expensive.

How to Choose the Best D.E. Filter

Here are a few things to consider when shopping for a D.E. Filter.

Type of Pool

D.E. filters work with any type of pool, including saltwater pools. But if you have an above ground pool, be sure to look for a D.E. filter model that’s able to hook up to your system. And keep in mind you might not necessarily need to invest in a D.E. filter if you have a smaller pool. Sand filters and cartridge filters are a more budget-friendly option and usually provide adequate filtration in pools with smaller surface areas.

Filter Size

Without the right sized filter and pump, your pool either won’t be cleaned enough or you’ll be wasting energy and unnecessarily shortening the lifespan of your filter.

The right size filter will turnover all of your pool water at least once a day, you’re. And to completely clean your pool water, you’ll want to turn it over three times in 24 hours. That means if you have a 15,000-gallon pool (a full turnover) you need a filter that can handle 45,000 gallons every day.

If you need help calculating your turnover rate and filter flow rate based on your pool size, be sure to check out our guide on How Long Should I Run My Pool Pump Every Day?

And be sure to consult your filter’s specs to make sure you’re meeting or slightly exceeding the gallons per minute required for your pool.

Filter Valve Type

A D.E. filter comes with a valve to help with backwashing and maintenance. Some D.E. filters feature a push/pull valve, which is simpler to use. Others have a multiport valve with multiple modes to handle various functions.

Multiport valve options commonly include the following filter settings:

• Filter: Normal mode for filtering the water and returning it to your pool
• Backwash: Reverses the flow of water to clean the filter and sends the water out the waste line
• Rinse: Removes loose particles and sends them out through the waste line
• Waste: Sends dirty water out through a waste line
• Circulate: Bypasses the filter to circulate your pool the water
• Closed: Closes off any water coming into the filter
• Winterize: Shuts down and protects filter for the colder months

Push/pull valves, on the other hand, are much more simple and easy to use. When the filter is in use, the handle is down, and when backwashing, the handle is up. This means it’s less likely to break or malfunction than a multiport valve, but you miss out on other options like Rinse and Winterize.

Types of D.E. Filters

You’ll find grid D.E. filters and quad filters. And grid filters come with either panels or fingers. The panels are usually curved, made with polypropylene, and arranged in a circular pattern. These panels are layered on top of one another, enabling better filtration and water flow through the tank.

Finger systems, on the other hand, use a grid that looks like vertical fingers. They can house up to 100 filters arranged in a concentric circle. This configuration gives you a more balanced water flow in the tank, during filtering and backwashing, so you have a higher flow rate and lower filter pressure.

Compared to finger systems, the grid design makes the filter system easy to clean. You do not need to remove them from the tank to clean or backwash.

Finally, there are Quad D.E. Filters. These look more like cartridge filters. Four cylindrical grids are made with thick woven polyester and offer an increased water flow rate and longer filter cycles.

Cleaning Requirements

One of the drawbacks of a D.E. filter is that it requires more effort to clean. But you don’t have to backwash it as often as you would a sand filter. And once you have done it a few times, it’s a simple thing to add to your regular pool maintenance routine.

Depending on the kind of filter you use, you may need to completely remove the grid from the tank to hose it down or soak it in muriatic acid.

Installation Requirements

Installing a D.E. filter isn’t all that difficult. After the grids are in place, hook the filter up to the plumbing and the multiport valve.
Keep in mind that filters won’t always provide adequate fittings for connecting everything. So it’s a good idea to make sure you have all the pieces to connect your filter to your existing pool equipment.

After that, mix your D.E. powder with water (according to your filter’s directions) and pour it into your skimmer with the pump running. It will be sent through the pool system. As it moves through, the D.E. sticks to the filter grid to create a D.E. “cake” that helps filter your pool water.

Filter Tank Construction

You can find pool filter tanks made with metal or high-quality plastic, such as ABS thermoplastic. A plastic tank is corrosion-resistant, which is crucial since it will be constantly subjected to water.

You’ll also need to consider tank size. Some models are large and round. Some are tall and slim. This of course relates to how large the tank must be to accommodate your pool, but it is also important if your space is limited.

Frequently Asked Questions About D.E. Filters

Looking for more help with D.E. filters? Here are some commonly asked questions and answers.

What does D.E. stand for in D.E. Filter?

D.E. stands for diatomaceous earth. It’s the fossilized remains of diatoms, aquatic creatures. It’s often found in river beds and the ocean.

How much does a new D.E. filter cost?

On average, the cost of a D.E. filter ranges from $500 to $2,000, depending on the size and complexity of the system. It is the most efficient filtration system, resulting in cleaner water, which helps prolong the life of your pool equipment.

Are D.E. filters better?

D.E. filters offer better filtration, but they aren’t the cheapest to buy and they require more effort to clear. If you’re worried about your budget, then a sand or cartridge filter will be better. If you want the cleanest water, then a D.E. filter is better.

Can I put D.E. in my sand filter?

Yes, you can put a small amount of D.E. powder into your sand filter after each backwash to help improve its filtration temporarily. But you assume some risk because sand filters are designed to be used with sand and it might void your filter warranty. And always start with a small amount, because too much will clog the system and possibly ruin it.

Which is better: a D.E. filter or cartridge filter?

D.E. pool filters are better for filtering out small particles but cartridge pool filters are easier to use. Which one is better depends on your budget and how much filtration you need.

The post D.E. Filter: How Does It Work and Is It Better Than A Sand Filter? appeared first on Swim University®.

So how do you choose the best one? It’s not about which one is the least expensive, though cost is certainly a factor. You want a filter that will trap contaminants, be easy to clean and maintain, and last more than just a few seasons. In order to make the best selection for your pool, first get a handle on your options.

Pool Filter Types

The first step to choosing the best filter is knowing what your options are. You have three types of filters to choose from: sand, cartridge, and diatomaceous earth, or D.E. Price, replacement frequency, and filtration rates differ by type. And if you’re wondering how to clean a pool filter, that will also depend on the type you select.

But before you can accurately compare pool filter types, how well they function, and how much work they require to maintain, you need to know about microns.

What the Heck is a Micron?

Pool filters measure the size of contaminants they’re capable of removing in microns. It’s short for micrometer, which is one millionth of a meter.

Having trouble picturing just how small that is? A single strand of human hair is about 50 microns, or about .05 millimeters in diameter. Some bacteria measures about 2 microns, or about .002 millimeters in diameter.

Whether they’ve been killed by chlorine or not, bacteria and other contaminants can only be filtered out if the filter media—the material that actually does the filtering—is fine enough to collect those teeny, tiny particles.

Sand Filters

If you’re on a budget, and you want to spend minimal time on maintenance, a sand filter is the best choice for you. It’s also optimal for large pools because it won’t clog as easily as other filters.

Your pool pump sucks water in from the skimmers, then pushes it through a large filtration tank full of sand. The standard media used inside the tank is #20 silica sand. It grabs particles that measure 20 microns and larger.

Each grain of sand is, for lack of a better word, prickly. If you could look at it under a microscope, you’d see it has lots of little rough edges all around it, which is how it grabs contaminants and debris that pass through the filter.

As weeks and years pass, and more water flows through the filter, those rough edges are slowly worn down by erosion, eventually becoming smooth surfaces that aren’t able to capture anything.

At the same time, the particles trapped within the sand will build up over the life of the filter. This can actually help trap smaller particles, even as the sand itself begins to smooth out. But eventually, it will prevent proper water flow through the filter, reducing the filter’s efficiency.

A pressure gauge on the side of the filter will alert you to increasing internal pressure—a sign it’s time to backwash the filter. This easy cleaning method the filter reverses the water flow, flushing all the debris to waste.

Because the silica captures particles of 20 microns or larger, you’ll really need to stay on top of your pool water chemistry. If there’s not enough sanitizer in your pool to kill those tiny, 2-micron bacteria, a sand filter isn’t going to catch them either, and they’ll be floating around in your pool with you.

Sand Alternatives

Although #20 silica is the standard media in sand filters, you can slightly increase filtration efficiency by adding D.E. powder after backwashing or replacing the sand.

You can also entirely replace the silica with one of two alternatives.

ZeoSand: This is made from a mineral called zeolite. You need only half as much (by weight in pounds) as standard pool filter sand. It’s crystal-like shape naturally traps smaller contaminants than silica. This improves water clarity and requires less frequent backwashing. ZeoSand lasts about five years, so its lifespan is similar to silica.

Filter Glass: This is finely crushed, recycled glass. Don’t worry about cuts—it’s smooth to the touch. It has a negative electrical charge which attracts positively charged particles, such as iron and manganese. You can use about 20% less filter glass than you would silica, while filtering debris as small as 5 microns. It also lasts up to three times longer than pool sand.

Cartridge Filters

Though they’re typically a bit more expensive than sand filters, cartridge filters are just as easy to maintain, and are more effective as long as you don’t have a huge pool.

Inside a tank slightly smaller than their sand cousins is a plastic cylinder surrounded by pleated polyester filter media and capped on each end. Water flows into the tank and through the pleats. Debris as small as 10 microns is captured in the filter, then clean water heads back to the pool.

Cartridges are energy efficient and inexpensive. As the filter collects contaminants, it’ll need cleaning. Rather than backwashing, you’ll simply remove the cartridge from the tank, and spray it with a hose to remove debris and dirt.

Occasionally, you’ll want to spray it down with filter cleaner, and on a regular basis, soak it in diluted muriatic acid or a chemical filter cleaning solution. While this is a bit more physical work for you than backwashing, it wastes less water.

Diatomaceous Earth (D.E.) Filters

The most expensive, maintenance-intensive option also happens to filter the smallest particles of all three types of filters: 5 microns.

D.E. filter tanks contain grids or “fingers” covered in the crumbly, white powder. The powder is made from the crushed fossilized remains of tiny, aquatic organisms called diatoms. Though D.E. and sand pool filters are different, the fossils in D.E. are also composed of silica. The powdery substance can be found in pest control, cosmetics, and even toothpastes, but D.E. made for pool filters is heat-treated to work as a filtration media. So don’t go sprinkling that pest-control powder into your pool filter when you run out of D.E., mm-kay? We’re talking about different kinds of pests here.

Backwash or Bump Cleaning

Like sand filters, a pressure gauge on the tank will let you know when it’s time to clean your D.E. filter. Typically, D.E. filters are backwashed just like sand filters. Some brands feature a bump handle, which lets you knock the used D.E. off the grids or fingers to clean.

Whether you backwash or bump the filter, you’ll need to add more D.E. powder after every cleaning. It can be difficult to determine exactly how much to add, so it’s especially important to disassemble and clean the filter by hand at least once a year.

How to Add New D.E. to the Filter

After you’ve cleaned your filter, rather than adding D.E. powder directly to the grids, you’ll get much better coverage if you add it through the pool’s skimmer.

• Mix the D.E with enough water to make a slurry, which will look like a thin, creamy solution.
• Make sure the pool pump is running.
• Slowly pour the solution directly into the skimmer.

As the D.E. passes through the filter, it will evenly distribute over the grids. You’ll need to wait a while before swimming to give the mixture time to fully integrate with the filter, so you may want to do this in the evening, and then run your pump overnight.

Illegal Backwashing

Some cities and towns appreciate backwashing as much as parents of small children do. Yours may have regulations specifying how to legally dispose of used D.E.

When it’s rinsed from the grids, D.E. powder can build up over time, creating a concrete-like residue that can clog storm drains or suffocate fish eggs.

Usually, you’ll be allowed to empty old D.E. into a disposable container and place it in the trash. Check with your local authority for specifics to ensure you don’t end up with a fine, and more importantly, don’t damage the environment.

Cancer Risk with D.E. Filters

Though D.E. is a known carcinogen, it has only proved cancer-causing in mice when inhaled long term.

Important: Safety first. Prevent accidental inhalation by wearing a chemical mask when you handle D.E. powder. Also, keep children and pets away from the area when you’re working with D.E. powder, and from the area where it’s stored. Immediately clean up any spilled powder.

Size Matters

A pool filter and a pool pump go hand in hand. The filter can’t function without the pump to move water through it. And neither will work properly if the pump isn’t the correct size for your pool.

Before you settle on a pool filter, make sure you have the right size pool pump.

Filter Size

Filters are rated by gallons per minute (GPM) per square foot. The filter flow rate must be rated at least the same GPM as your pump, or higher. With pool filters, it’s best to err on the larger size so it can handle the power of your pump. A helpful rule of thumb is to choose a filter with at least 1 square foot per 10,000 gallons pool capacity.

Bargain shoppers beware. It’s nice to save money when you can. But off brands can come and go, leaving you searching for replacement products from defunct companies down the road. Buying a pool filter from a trusted manufacturer can save you headaches and dollars in the long run.

How to Troubleshoot a Pool Filter

Because it plays such an important role in keeping your pool clean, it’s imperative that you keep your pool filter in good condition. Filters run into a few common problems, and knowing how to recognize them will help you troubleshoot, and then repair them.

Leaks

Do you hear or see water dripping around the filter? Have you noticed a small puddle forming below it? If so, your pool filter may have sprung a leak.

A leak in your filter won’t cause a significant drop in your pool’s water, but it’s still important to identify and repair the problem before it worsens.

First, try to identify the source of the leak. Check the filter’s tank for any holes. If you do find one, you may be able to patch it. But be prepared to replace the tank because a patch likely won’t hold up for very long.

If you have split-tank filter, check the belly for leaks. Remove the band and inspect the O-ring for wear and tear or debris. If it’s worn out, you’ll need to replace it. Remember to add pool gasket lubricant to help in sealing, and to keep the ring hydrated, which will help it last longer.

Cycle Problems

If your filter often seems to be running only in short cycles, and you notice this happening even when the pool isn’t in use, the filter could have a flow rate problem.

The likely problem is that the flow rate is too high, which means your pool pump may be too strong for your filter. It could also mean your filter isn’t big enough for your pool.

If your filter is the right size, you may need to backwash the filter for a longer period of time. When backwashing, remember to continue the process until the water in the sight glass is clear. This could take several minutes.

The filter may also be running in shorter cycles because algae or other debris is clogging it. Clean the pool filter thoroughly, and consider replacing it if it seems worn out.

Filter Material in the Pool

It’s not uncommon to see some filter material in the pool after backwashing, regardless of what kind of filter you have. But if you start noticing it when you haven’t just backwashed, you may have a problem.

The first thing to check is the bolts holding the filter in place. If they’re loose, it could allow particles to escape into the pool. If they’re not, look for other causes.

If you have a sand filter, the filter lateral or standpipe may be broken. If it is, you’ll need to replace it.

If you have a D.E. filter, there could be tear in the fabric of the grid, or even a crack in the grid manifold. Again, if this is the problem, you’ll need to replace the manifold.

Water Pressure Problems

Checking the pressure gauge should be part of your regular pool maintenance. Problems with water pressure can affect your pool filter’s performance.

If the pressure is too low, there could be a blockage in the system somewhere before the filter. If the pressure is too high, there could be a blockage at some point after the filter.

Thoroughly check the filter system to see if it’s clogged, and clean it if necessary. If you don’t find any clogs, and the filter is clean, check the return valve to make sure it’s completely open, and then double check the lines to see if you can find a clog.

Hayward is one of the biggest and most-trusted pool brands on the market. And while ost variable-speed pumps are oversized, The Max-Flo VS is the perfect size for any pool, particularly with 1.5″ or 2″ plumbing. After reviewing several pumps, we choose this one as our top pick because we liked the built-in programmable timer and freeze protection.

What is a VS (Variable-Speed) Pool Pump?

Also known as multi-speed pumps, variable-speed pool pumps are one of three types of swimming pool pumps you can buy.

1. Single-Speed Pool Pumps are the entry-level and the least expensive pumps that operate at full horsepower whenever you turn them on.
2. Dual-speed pumps let you choose low- or high-speed operation. Choose the low setting to save power and money when you’re simply filtering the water. Choose the high-speed setting when you’re doing more demanding tasks, such as vacuuming or adding chemicals.
3. Variable-speed pumps let you control the speed, whether low or high or anywhere in between. Most of these energy-efficient pumps are powered by a different type of motor than the first two, called a permanent magnet motor. This type of motor is used in magnetic resonance imaging (MRI) machines and electric cars. It’s typically more efficient than the induction motors in single- and dual-speed pumps.

Some newer variable-speed pumps feature drop-in replacement, making the upgrade simple. Some of them can even be programmed to operate at optimal speeds for certain tasks, such as filtering and running deck jets. They’re also more reliable than the other two types of pumps.

Are Variable Speed Pool Pumps Worth The Money?

Yes! The ability to simply turn down your pump will cut down on energy use, but there’s a little more to it than that. Before you shell out the cash for a fancy new pump, learn how it will put money back in your pocket.

1. Variable-Speed Pumps Consume Less Power

Pumps don’t need to run at full power all the time to keep your pool water clean. In fact, when you’re filtering your water, your pump can run at a much lower speed than when it’s doing more demanding jobs, such as running a water feature.

When you choose a variable-speed pool pump, you’ll have a higher up-front cost, but bigger savings over time. Typically, pool owners who switch to variable-speed pumps recover the cost of the pump in energy savings in less than two years.

You could save up to 83 percent in annual energy costs (give or take, depending on where you live and other variables) just by upgrading your pool pump.

2. They Help Filtering Go Faster

We all want to err on the side of caution, but running your pump too often won’t do anything for your pool, and it will cost you.

Several factors affect how many hours per day you run your pool pump, including the pump’s horsepower, pool usage, water balance, and the region you live in.

By choosing a variable-speed pump, you can run it at lower speeds (although this may mean you need to run it for a longer period of time) during filtering hours, consuming less energy, filtering more effectively, and lowering your costs.

3. They Can Help You Avoid Fines

Several states have energy efficiency laws regarding pool pumps. These laws are typically created as part of larger energy-efficiency laws, but they’re also part of the building codes that can be enforced and result in fines if violated.

Some states let you choose between a variable-speed or dual-speed pump, but if you currently having a single-speed pump, you may be able to keep using it if it’s less than one horsepower.

If that single-speed pump fails, you may be able to get away with having it repaired rather than replacing it, but it’s really to your benefit to go ahead and upgrade to a variable-speed or at least a dual-speed pump at that time.

Check your state’s energy efficiency laws to make sure your pool pump is in compliance, and to find out whether you need to upgrade. If wading through pages of state legislation isn’t your idea of fun, you can also consult a pool professional.

4. They May Help You Get Money Back

Buying a variable-speed pump may also qualify you for incentives such as utility rebates. Power companies sometimes offer rebates to entice you to reduce your power consumption by using energy-efficient appliances and making smart choices. This enables the utilities to meet their legal obligations to reduce energy use.

Tip: Check your local power company’s website for rebate information before you buy a pool pump. You can also find incentive information for your state on the U.S. Department of Energy website.

Low Pool Pump Speeds Mean Low Noise

Think of the sound your single-speed pump makes when it kicks on. Has it ever woken you up at night? Well, when you switch to a variable-speed pump, you’ll never again bolt awake in bed wondering if a helicopter just landed in your yard.

Single-speed pumps run at 3,450 revolutions per minute (RPM). Variable-speed pumps can run as low as 600 RPM. The lower RPMs significantly reduce motor noise, making the variable-speed pump a far quieter option than that old single-speed.

Set your timer to turn the variable-speed pump on at a low setting overnight to turn over your pool water during non-peak power hours. You’ll save money, clean your pool, and avoid a confrontation with grumpy, sleep-deprived neighbors.

Programming Options for Variable Speed Pool Pumps

Some variable-speed pumps have built-in programming features that make them super energy efficient. These pumps allow you to program them so they use just enough power to perform a particular task, such as operating a waterfall.

With these automation options, you don’t have to remember to switch speeds yourself. The pump does it for you automatically. It’s pretty simple to program, too. If you can set your pool timer, you can automate your pool pump.

How to Choose the Right Size Pool Pump

By now, you should be ready to kick that old single-speed pump to the curb, and make the investment in long-term savings with a variable-speed pump. But how do you pick the right size pump for your pool?

It’s not difficult and requires just a bit of math. This video will help you choose the right size:

Final Considerations for Buying a Variable Speed Pool Pump

Now that you know how to choose the correct size pump, you must keep a few other details in mind to choose the best pump for your pool.

1. Flow Rating: Your filter is built to withstand a certain volume of water flowing through it. Check your filter’s flow rating to determine the maximum horsepower acceptable for your setup.
2. Pipe Size: You’ll run into problems if the PVC used to plumb your pool is too small in circumference to handle your pump’s horsepower. Older pools typically used 1.5-inch diameter pipes, which are not large enough to handle water flow from a high-horsepower pump. Those with 2.5-inch or 3-inch pipes may choose a pump with more than one horsepower.
3. Horsepower: More isn’t always better. Even if your pipes could handle a three-horsepower pump, you may not need it. Choosing one that’s too high is a waste of power and money. If you’re in between two sizes, choose the one with more horsepower.
4. Voltage: Pool pumps are available in either 115-volt or 230-volt models. You can use a multimeter to check the voltage coming to your existing pump. The output terminals on your pump timer are an easy place to use the multimeter. If you’re not comfortable using a multimeter or working with electricity, ask a pool pro to help you.
5. Side or Top-Mount: The mount you need depends on your setup. Water is pumped into the filter, so the location of the filter will determine whether you need a side- or top-mount pump. If you’re building fresh or moving everything around, side mounts may offer easier access.

Why is a Variable Speed Pool Pump Better?

The bottom line is variable-speed pumps will keep your pool water moving and filtering all day long without increasing your energy consumption and your electric bill. In other words, you’ll get proper pool water circulation for less money.

Happy Swimming!

The post Variable-Speed Pool Pumps: A Comprehensive Guide appeared first on Swim University®.

Whether this is familiar, or your pump just suddenly died, or you need a new pump for a new pool, you want to choose the best one for your pool and your budget. And remember, you’re making a long-term investment in your pool’s health. The key is knowing what your pool needs, and what features to look for. And while you’re at it, don’t forget to brush up on some pool pump troubleshooting for those inevitable problems that will crop up.

What Does a Pool Pump Do?

It’s the heart of your pool’s plumbing system. Without it, you won’t have any pool circulation, and water won’t flow through your filtration system to be properly cleaned. And that means, a dirty, nasty pool full of stagnant water. Basically a cement pond, but one you don’t really want to swim in.

Pool Pump Anatomy

Before you start looking for a new pump, it’ll be helpful to understand how it works. A pool pump is comprised of three main components: the housing, the impeller, and the motor.

Cutaway of a Hayward Super Pump

The housing consists of a bucket and basket with a clear lid on top. Pool water is sucked into this bucket, through the basket, and up to the filter.

The impeller is a fast-spinning, inverted blade that sucks the water in and pushes it through to the filter.

The motor is attached to the back of the pump housing, and its sole purpose is to spin the impeller. You’ll sometimes hear it referred to as the pump and motor, or just the pump.

Pool Pump Types

Since they were first invented, pool pumps have come a long way, and have evolved from just one to three types on the market.

Single-Speed Pumps

The original of the three, the single-speed refers to the fact that the motor spins the impeller at only one speed according to the horsepower of the motor.

If you are replacing a single-speed pool pump, we recommend you upgrade to at least a dual-speed or better. They’re more efficient, and they turn the pool water over more quickly.

But there’s something else to be aware of. Some states, such as Arizona and California, prohibit the installation of new single-speed pool pumps.

Check with your state before you buy a new pool pump.

Dual-Speed Pumps

As the name implies, these pumps have two speeds: low and high. The high speed equates to that of a single-speed pump. The lower speed uses less energy, but may not be as efficient at water turnover. This will depend on your pool’s volume.

Variable-Speed Pumps

Yes, these pumps are more expensive than single- or dual-speed pumps, and rightfully so. This where that long-term investment in your pool comes in.

Instead of an induction motor like the other types have, a variable speed pool pump uses a permanent magnet motor, the kind used in electric cars. A magnet motor creates less friction than an induction motor. Less motor friction equals higher efficiency.

Variable-speed pumps also consume less power and turn the water over more quickly. They also run at lower revolutions per minute (RPM) than single- and dual-speed pumps, so they’re quieter. You may even get a utility rebate when you buy one.

Pool Pump Features to Look For

You may know which type you want, but before you make the final decision, be sure you’re choosing a pool pump with the right features for your setup.

Inground or Above Ground

You can find pumps for both above ground and inground pools. While they’re usually interchangeable, it’s best to get a pool pump designed for your type of swimming pool.

Horsepower

The more powerful your pool pump is—meaning, the more horsepower it has—the faster it will turn the water over, so you can run it less often and for shorter periods of time.

But this also depends on the size of your filter and the filtration system’s pipes. A pump with too much horsepower can overwhelm a small filter. But if your system uses three-inch pipes, you can install a three-horsepower pump, which will work more quickly.

But three horsepower can be too much if you have a small pool, which will just waste energy and cost more money. Be sure to choose a pump that won’t overwhelm the filtration system, but still has enough horsepower to turn over your pool’s volume at an adequate rate.

Pump Housing Mount

You have two options here: top mount or side mount. This indicates where the pool pump’s output—which leads into the filter—is located.

If your filter’s intake is positioned above the pump, you need a top mount. If the filter intake is located next to the pump, you need a side mount.

Be sure you check your filter’s intake position before you buy a pool pump to make sure the housing mount is in the correct place.

Pump Motor Voltage

Your pool pump can either be hardwired into your electrical system or it may require an outlet to plug into. Know what you’re getting into before buying your pump.

You’ll also need to determine whether the pump runs on 110 volts or 220 volts. Most above ground pools require a 110-volt pump. But you’ll need to determine what voltage you’re working with if you have an inground pool.

How to Choose the Right Size Pool Pump

To remain clean and clear, all the water in your pool must be completely filtered at least once a day. This is called the turnover rate. Your pump must be large enough to turn over your pool’s full volume at least once per day.

To calculate your pump’s turnover rate, you’ll first need to calculate your pool’s volume. If you’re not sure how to do this, use our pool calculator to figure it out:

Pool Volume Calculator Click on your pool shape to calculate the volume of water.

Rectangle

Round

Get Pool Volume

Get Pool Volume

Once you have your pool’s volume, divide it by eight to determine the number of gallons per hour (GPH) that need to be pumped through the filter.

But instead of GPH, most pool pumps go by gallons per minute. To get that figure, divide the GPH by 60 to calculate how many gallons per minute (GPM) need to be pumped for full turnover.

So your formulae will be:

Total Pool Volume ÷ 8 = GPH

GPH ÷ 60 = GPM

It won’t be as accurate as using a calculator or doing the math, but you can also get an idea of your pool’s volume here:

Once you have all the numbers, you can find the size of pump that will accommodate the GPM required for your pool and turn over the pool’s water in one eight-hour period. If you have to choose one that pumps a little more than necessary, that won’t cause any problems. Just don’t go below the required GPM, and you’ll be fine.

Pool Pump Troubleshooting

It’d be great if your pump just ran forever and never encountered any problems, right? Heck, it’d be great if everything worked that way.

But the time will come when your pump acts up, and you’ll need to fix it. Knowing some of the most common pump problems will help you deal with them when they occur.

The Pump Is Leaking

The most common causes for pool pump leaks include a bad impeller housing O-ring, bad shaft seal, bad thread sealant, and shrunken threads on the discharge pipe.

In most cases, these parts can be purchased and replaced rather easily at a fraction of the cost of calling a pro. Determine which part is leaking, take the system apart, replace it, and you will be back up and running in no time.

The Pump Fails to Pull Water

When water isn’t being pulled in to the pump, it can’t reach the filter and pass through the system properly. The first thing to look for is a clog in the system.

First, check the skimmer and the pump baskets to make sure they’re not clogged. Next, check the impeller for debris impeding its movement. Open up the pump and clear away any debris.

Another potential cause can be an air leak in the suction line. Since air has less mass than water, the pump will suck in air instead of water. Check the lines for leaks and patch up any you find.

The Motor Won’t Start

The first thing to check is the breaker to make sure it hasn’t been tripped. If the breaker is on, but the pump still won’t turn on, there’s likely an electrical problem, and you may have to replace the motor.

Note: If you’re not comfortable working with electrical systems, this may be an instance where calling in a pro is the best choice.

The Motor Spontaneously Turns Off

If this happens, the motor is most likely overheated. Check the pump’s air vents to make sure nothing is obstructing air flow. If it continues to happen, you may want to install something to shade the pump, if possible.

If the problem persists, it could be an electrical issue, and you may want to call in a pro, unless you’re an electrician.

The Pump Motor is Making Noise

All pump motors will make some noise. But if your pump is making a racket that sounds different from when it’s running normally, you could have a problem.

If it’s just vibration, placing the pump on a rubber pad may do the trick. But if it’s a low, growling sound, the problem could be cavitation, which means the pump isn’t getting enough water, and is taking in air.

First, prime the pool pump.

If priming the pump doesn’t stop the noise, check the intake lines for clogs, and make sure none of the lines are leaking. Once those things are fixed, the pump should quiet down.

If the pump is making a screaming noise, it’s likely the bearings have gone bad. Or it’s being terrorized by the neighborhood’s feral cats. But it’s probably the bearings. If so, you’ll need to replace them.

While the parts are inexpensive, this fix will require quite a bit of labor as the motor will have to be shut off, disconnected, and disassembled. So have your tools ready for this one.

Don’t Hesitate to Call a Pro

If you can repair it, you have the tools you need to do it properly, and you’re comfortable taking apart a pump motor or working with an electrical system, by all means do it. The DIY approach can save you money, plus you get the satisfaction of fixing something yourself.

But if you don’t have the necessary knowledge or skill, or you’re uncomfortable tackling a repair on your own, by all means, call in a professional.

After all, this is the heart of your pool’s plumbing system. If you aren’t confident in your ability, you could actually do more harm than good. Call in a pool pro to take care of the repair the right way the first time.

And hey, you can watch what they do so you might be able to take care of the problem on your own next time.
