Pool Losing Water When Pump Is On

My Pool Is Only Losing Water When My Pump Is Running

Take a mental picture of it. The next time you go out to your pool, you’ll notice that the water level is lower than usual. As a result, you fiddle with the filter and valves while also adding extra water. After a few days, you notice that the water level has dropped once more. It suddenly dawns on you: “My pool is only losing water while my pump is operating,” you realize. Great. You understand, being the pool expert that you are, that it is not ideal to have your pump not working at all times.

Let’s look into it a bit further.

My Pool is Only Losing Water When My Pump Is Running

Every swimming pool has water loss, whether as a result of evaporation or spillovers. If, on the other hand, you’re losing water at a rapid rate, it’s something you should address as soon as possible. If you’re reading this post, I’ll presume you’ve gone through the process of elimination and have determined that your pool only leaks when you turn on the pump. If this is the case, continue reading. However, this does not necessarily imply that the leak is occurring at your pump. It does, however, indicate that you have a pressure-side leak rather than a suction-side leak.

Pressure-side Return Leaks

The majority of the time, if you’re losing water while your pump is working, you’re dealing with a pressure-side return leak. Whenever your pump is turned on and running, the piping following the pump is put under pressure. Frequently, this might result in minor leaks and water spraying through your line (from the filter to your return jets.) The good news is that It is possible to eliminate any form of air leaks prior to the pump and then shift your attention to after the pump. The bad news is that You must now locate the source of the leak.

Check All the Connections

The first places you should look for leaks are the connectors, unions, elbows, and the hoses connecting your pump to your filtration system. Water leaks can be caused by a variety of factors including normal wear and tear, overtightening, and physical damage to unions. Make sure to inspect your pump, filter, chlorinator, and heater, among other components of your system. If your pool heater is leaking, you need to take action as soon as possible. A leaky heater can have an influence on the internal parts, which may or may not be covered by the manufacturer’s warranty depending on the circumstances.

In many cases, the coupler, unions, or hose are subjected to significant quantities of pressure, causing them to fail and leak.

Filter Multiport Valve

The multiport valve is vital because it aids in the regulation of the flow of water into and out of your pool. As a result, a lot may go wrong as a result of this. Look for leaks in the inlet and outlet ports of the valve, as well as in the region around the cover. Another cause of leaks is the backwash hose, which is a typical occurrence. Check the end of the backwash hose to see if there is any water running when it shouldn’t. Internal leaks can also develop in a faulty filter multiport valve if the filter is not functioning properly.

The spider gasket, which is located inside the valve, is another potential problem. Water leaks can be caused by damaged or defective spider gaskets, to name a few possibilities. For further information, we recommend that you read the following:

Return Jet/ Return Jet Fittings

This valve is vital because it aids in the regulation of the flow of water into and out of your swimming pool. This has the potential to cause a slew of issues to arise. Look for leaks in the inlet and outlet ports of the valve, as well as surrounding the cover. Lastly, the backwash hose is another major cause of leaks. Keep an eye out for any water pouring out of the backwash hose that should not be there! Filter multiport valves that are malfunctioning may also develop internal leaks. It is possible that pure water will be lost into the waste line or backwash line as a result of this.

Certainly, leaking water can be caused by damaged or defective spider gaskets.

Pressure Test Your Return Lines

Unfortunately, some leaks aren’t immediately obvious. If you are unable to locate any leaks, you may be required to do a pressure test. If you are not familiar with the process of pressure testing your return lines, we recommend that you hire a local pool technician. In any case, you may execute a pressure test on your own with a few winterizing plugs, a small compressor, and a few feet of piping to attach a Schrader valve and gauge to the line that exits the filter. Your local hardware and supply store should have pressure testing kits available for purchase.

The test, on the other hand, will not reveal the precise location of the problem.

Can’t Find The Leak?

What happens if you are unable to discover the source of the leak? You should consult a professional since, after all, that’s what they’re there for. In all seriousness, there are times when it is best to seek the assistance of a professional. Leak detection firms can conduct a variety of tests that will aid in determining the location of the leak as well as assisting in the repair of the leak. If you believe you may have a suction-side leak as a result of reading this post, we urge that you read our articleHERE.

My Pool Loses Water Every Day, Is This Normal?

How Much Water Loss In a Pool Is Normal?

According to whether you are in a wet, rainy time or a drought, the amount of water lost might vary greatly. The water in your pool is most likely between 18,000 and 20,000 gallons. A drought may cause many inground pools to lose between 60 and 120 gallons of water per day just via evaporation. The loss of water might result in a high municipal water bill or the overworking of your water well’s pump. As a result, it’s logical that you want to make certain that none of this valuable resource has escaped from your pool.

If you’ve recently updated the landscaping surrounding your pool, you may notice a difference in the amount of water that evaporates.

In addition to reducing the sun’s rays, adding a screen or shade to your home can help you conserve water.

1. Pool Loses Water All Day

Due to the shifting weather patterns, it might be difficult to detect pool leaks. Thunderstorms in the afternoon may cause the water level in your pool to fluctuate. Pool chemicals, such as chlorine, are notorious for evaporating quickly. Stabilizers can be added to your pool water to keep the chemicals contained within your pool and out of the air. Generally speaking, if your pool loses more than 14 inches of water in a humid area and more than 12 inches of water in a dry environment, you may have a pool leak.

2. Pool Loses Water Overnight

The amount of water that evaporates from your pool overnight might vary depending on the time of year you are swimming in it. Despite the fact that the days may be warm enough for swimming, chilly nights will drop the temperature of your pool. When you use a pool heater, the water in your pool heats up and evaporates more quickly. Because the summer air remains warm overnight, the water in your pool will evaporate even more quickly. The use of a cover for your pool might assist to prevent water and heat from leaking into the surrounding air.

3. Pool Is Losing Water When the Pump Is Off

The level of your pool may be lowering by more than 1/4–1/2″ every day if you’ve shut off your pump system for a day. This indicates that you may have a pool leak. It is likely that the leak is located either within the pool’s construction or on the suction side of the pool pumping system. Examine the area surrounding drains, your skimmer, pipework, and fittings on the intake side of your pool pump for any signs of corrosion.

4. Pool Is Losing Water When the Pump Is On

If the water level in your pool drops only when the pump is turned on, it is unlikely that the pool construction is to fault.

Verify that the pipes and components on the pressure side of your pool pump are in proper working order. Leaks might be difficult to detect. Look for puddles or areas of ground that appear to be wetter than the rest of the area.

5. Pool Loses Water in the Winter

Maintaining your pool’s temperature throughout the winter or during the colder periods of the swimming season will help to reduce evaporation. When your pool is not in use, it is a good idea to cover it. Reduce the temperature of your pool when you aren’t planning on swimming to reduce the quantity of water that evaporates from your pool throughout the winter.

6. Pool Is Losing 1 Inch of Water Per Day

If you are losing more than 12″ of pool water every day, you most likely have a leak in the construction of your pool or in your pool pump system. You should contact your pool service provider to have a full leak inspection performed. It’s possible that you won’t be able to keep up with the replenishing of your pool at this time. Taking in air from the skimmer might cause harm to your pump system, which can result in a clogged system. Additionally, if water escapes from the pool and saturates the surrounding soil, your pool may possibly burst out of the ground.

7. Pool Is Losing Water After Frequent Use

It’s also possible that you’re losing water simply because you’ve been using your pool more. A lot of splashing about might cause water to be forced onto your deck and into the surrounding air. Even if you detect a slight decline in water level after a week of heavy pool usage, it is possible that there is no problem at all. If your filtration system requires backwashing maintenance, you will experience water loss as a result of the procedure. Having a more frequent backwashing schedule is something you or your pool cleaning provider may have considered.

Common Areas Where Your Pool Might Be Leaking

Although any element of your pool that stores water might be the source of a leak, there are few frequent places to look for signs of a leak. Skimmer. The pool skimmer is one of the most common culprits when it comes to pool leaks. It is possible for the skimmer materials to become damaged. It is possible for the skimmer to develop a leak at the point where it connects to the pool. It is also possible for the pipe leaving the skimmer to develop a leak. First, make sure that all of these locations are checked.

  • Another place where pool leaks might begin is in the return pipe of your pool.
  • Check the ground for soft, moist spots that might be caused by leaks that are still active.
  • No pool owner wants to hear that their main drain is clogged or that their filter is clogged.
  • You may choose to speak with your pool builder about gaining access to the pool and assessing whether or not your main drain is leaking.
  • It is possible that any holes in the construction of your pool will ultimately leak.
  • Your pool care provider can assist you in determining the source of any issues and resealing your fixtures.
  • Finding a leak in the construction of your pool might be a simple process.
  • Visual inspection of the surface or tiling might reveal certain leaks that would otherwise go undetected.

A dye test may be required for other types of leakage. Your local pool supply business may be able to assist you with some supplies and suggestions. If your pool is beginning to show signs of wear, it may be necessary to hire a pool rehabilitation firm to repair or resurface your pool.

What to Do If You Think You Have a Pool Leak

There are certain frequent spots to check for leaks in your pool, even though any portion of your pool that collects water might be at fault. Skimmer. Pool leaks are frequently traced to the pool skimmer, which is one of the most common culprits. Occasionally, the materials used in the skimmer will become damaged. It is possible for the skimmer to develop a leak at the point where it connects with the pool. A leak can also develop in the plumbing that leads from the skimmer to the tank. Prior to anything else, double-check all of these areas!

  1. Since it is underground, it may be difficult to gain access.
  2. Drainage from the main line A leaky main drain is the last thing any pool owner wants to hear.
  3. In order to get access and determine if your main drain is leaking, you may want to call your pool builder.
  4. It is possible that the waterproof barrier surrounding your pool lights and jets will be compromised.
  5. Building a Swimming Pool Locating a leak in the construction of your pool is not always difficult.
  6. With a visual check of the surface or the tiling, you may be able to identify certain leaks.
  7. A variety of items and assistance are available from your local pool supply business.
  1. If you have an automatic fill system, make sure it is turned off. You should turn off your pool pump. Pour enough water into your pool to reach the right level. Mark the level of the pool water on the skimmer
  2. Fill a bucket almost to the brim with water
  3. Make a mark on the water level in the bucket
  4. Place the bucket on the first step of your pool
  5. After 24 hours, check the water levels again. Make a list of everything
  6. Fill the tank with water and repeat the test while the pump is operating constantly.

If the water level in both your bucket and pool drops by the same amount, you’re most likely losing water through evaporation. If the water level in the pool has dropped more than the level in the bucket, you most certainly have a pool leak. A leak in the structure of your home or a leak in your suction side piping might be the cause of the low water level when the system is turned off. If your pool only loses water when the pump is working, it’s likely that you have a leak in the pressure side piping of your pool pump system.

Pump Off Test – Pool Leak Tests

Performing a pump on / pump off test can assist us in determining where the source of your pool leak may be coming from. There are three primary places where a pool will leak:

  1. A leak on the pressure side of the pool plumbing pipes (the returns)
  2. And The presence of a suction side leak in the pool plumbing system (skimmers and drains)
  3. A pool leak that is not caused by plumbing (pool liner, pool light, skimmer mouths, surrounding penetrations)

Pump On / Pump Off Test Steps:

  1. Pools are normally filled halfway to the skimmer, tile line, or liner design. Make two precise marks on the pool’s surface, up to the point where the pool is completely filled
  2. For 12-24 hours, leave the pump turned on and record the amount of water that has been lost. Refill the pool with water and make another correct mark if there is a miscalculation. Turn off the pump for 12-24 hours and check for water loss to see if there is any.

WARNING: Make an effort to do these tests at the same time of day and for the same amount of time each day.

  • If the pool loses more water when the pump is turned on, this indicates a leak in the pressure side of the pool’s plumbing system. If the pool loses more water when the pump is turned off, this indicates that there is a leak in the suction side of the pool plumbing. If the pool lost the same (or nearly the same) quantity regardless of whether the pump was running or not, the leak is most likely not connected to the plumbing
  • Otherwise, the leak is due to the plumbing.

My Pool is Losing Water!

A leak on the pressure side of the pool plumbing indicates a leak in the pool’s water-loss system when the pump is turned on; If the pool loses more water when the pump is turned off, this indicates a leak in the suction side of the pool’s plumbing system. It is most likely not a plumbing issue if the pool loses an identical (or nearly same) quantity regardless of whether the pump is on or off; otherwise, it is.

How often should I have to add water to my pool under normal conditions?

Pool water will be lost through a variety of regular processes, including splash-out during usage, backwash waste, and evaporation. You should be aware of these losses. Depending on where you live and the environment, you may be able to recover some of the water through rainfall. When adding more than two inches of water to your pool each week, however, there is a good likelihood that you have a severe leak somewhere in your pool system. Rather than just replenishing the water tank on a regular basis and disregarding the loss, invest some time and money to correct the leak as soon as you realize it is occurring.

Why do pools leak?

Pools are created in such a manner that they are completely impermeable, and even though they appear to be simple structures, there are several components and pieces that go into maintaining them that way. Seals weaken with time, pools may move as a result of shifting earth, and the ground into which the pool was excavated may settle. Pools frequently leak via plumbing fittings, accessories such as light fixtures, and even through the shell or liner of the swimming pool. It is vital to locate and repair leaks in order to save money on items such as water, heat, and chemicals, as well as to prevent the eroding pool structure from accumulating water and washing away dirt from the bottom of the pool.

How do I find out if I have a leak?

Leak detection is a difficult and time-consuming process that takes a long period. In rare circumstances, a specialist may be required to find the problem as well as to remedy it. But you may be confident that the majority of pool leaks are caused by something small and can be repaired for a reasonable price. Using some of these frequent scenarios to troubleshoot your pool, you may be able to save money by either identifying and halting the leak or by being able to inform your local pool specialist precisely where the problem is.

This will allow you to observe how much water your pool is losing.

Both the bucket’s water line and the pool’s water line should be marked.

It is quite likely that you have a leak if you observe that the pool has lost more buckets than your control group (the bucket).

If you’re not sure whether or not your pool requires more than 2 inches of replenishment water each week, this is a wonderful approach to double-check your assumptions. It is possible to avoid evaporation by using a sun cover or liquid solarcover.

Here are some other things to check before calling a service person for repairs:

Is the pool leaking when the machinery is running or only when the equipment is switched off and on? This is an excellent place to begin. Unless you have a pressure-side return leak, you should switch off all of your pool equipment, such as the pumps and filters, if you see that you are still leaking water. Because of the operation of the filter pump, the plumbing on the pressure side is put under pressure. Initially modest drops can quickly evolve into large amounts of spray, which can cause your pool to lose water more quickly than you would expect.

  1. If your pool is leaking even while none of your equipment is operating, you may have a suction-side leak.
  2. Air is frequently sucked into the pool through leaky voids, preventing the pool from leaking.
  3. Air bubbling OUT of return pipes or air piling up in the filter tank are further signs that something is wrong.
  4. What should I do if my pool is always leaking?
  5. Put a little amount of pH indicator test reagent near the crack when the pump is turned off and the water is quiet.
  6. If the dye is drawn inside the fracture, you’ve discovered the source of the leak.
  7. If this happens, you may fix it by putting putty or another caulking agent in the aperture of the conduit at the rear of the socket that is appropriate for the pool building material you are using.
  8. When there is a divide between the plastic skimmer and the pool, the most typical source of leaks is this (most often in concrete shells).
  9. Stick Underwater Glue, as needed.

My water leaks to a certain level and then stops. What’s going on?

If you are losing water and then notice that the flow appears to level out at some point, this might help you establish where the leak is coming from. Consider the following scenario: if you close the skimmer valve and the water descends below the skimmer and continues to flow, the problem is most likely not the skimmer. Water that drops below the level of an underwater light and then stops leaking is a strong indicator of where the water is escaping. In order to determine if your water has stabilized at a specific point, do the dye test in regions around that level.

  1. A suction line leak, most usually immediately under the skimmer, may cause your water level to drop to the bottom of the skimmer and come to a complete stop.
  2. If this happens, call your pool service company immediately.
  3. In the event that you have observed water seeping around the pool and producing puddles or moist soil—particularly between the pool and the equipment pad—you should have someone come out and fix the problem as soon as possible.
  4. Consider checking the filter, pump, heater, and all of the valves to see if you can detect any spray or anomalous water accumulation.
  5. Turn the pump on and off several times, paying attention to how the water spray varies with each adjustment.
  6. Is the vinyl in your pool still in good condition?
  7. It is significantly more vulnerable to rips and tears than your typical plaster or concrete pool, due to the thinness of the material.
  8. Also search for sinkholes underwater that appear to be caused by a leak in the liner, where the fill sand beneath the liner appears to have been swept away.

It is possible to repair vinyl linings yourself using vinyl patches, but the entire lining should be replaced every ten to fifteen years or so. Keep in mind that you might have many leaks at the same time.

How much does leak repair cost?

Because pool leaks can be difficult to locate and analyze, it is possible that a service technician will need to come out more than once to fix them. For a regular leak repair, I would estimate that the average cost is between $150 and $250 dollars. If you have a major problem that necessitates concrete cutting, the cost can certainly be substantially more. Just remember that it’s best to discover the problem as soon as possible and attempt to resolve it before it becomes out of hand and costs you a lot of money.

It is hoped that some of this troubleshooting can assist you in saving time and money by allowing you to identify and possibly even solve the problem yourself when you discover your pool is losing water.

How to Find a Leak in Your Swimming Pool

Documentation Download Documentation Download Documentation The natural evaporation of water from your pool, as well as splashing out of water and backwashing your filter, causes some water loss. However, if you find yourself adding more than two inches of water to your pool on a weekly basis, you may be dealing with a leak. Isn’t that right? Not so fast, my friend. Before you hire a local pool technician, inspect your pool and assess whether or not you can solve the problem yourself.

  1. Read More About ItRead More About It The natural evaporation of water from your pool, as well as splashing out of water and backwashing of your filter, is inevitable. A leak, on the other hand, may be present if you find yourself adding more than two inches of water to your pool each week. Isn’t it true? Don’t get your hopes up just yet! Before you hire a local pool technician, inspect your pool and evaluate whether you can solve the problem yourself.
  • Is there any water leaking from the equipment pad? Examine the filter, the pump, the heater, and the pipe valves with care. Is there a wet space surrounding the pool that I may use? Examine the ground for signs of wetness. Take a stroll around the pool, as well as beside the pool and its equipment. Make a visual inspection for damp soil and sunken or crumbling places. Do you have a pool with a vinyl liner? Keep an eye out for tears or separations around all of the fixtures, including skimmers, return lines, the cleaner line, the lights, the steps, and the corners.
  • 2 If you wish to double-check whether or not there is a leak, use one of the ways listed below. Checking for pool leaks may be done in numerous methods
  • The most common are as follows:
  • The skimmer should be used to mark the water level in the pool. Make a note on the water level using a piece of tape or a grease pencil. After 24 hours, go back and check the mark. No more than 1 4 inch (0.6 cm) of water should be lost from your pool every day. A leak is evident in the absence of this. Placing a bucket filled with pool water on a pool step will help to prevent slipping (weight it with a rock or brick). Mark the water level on the inside and outside of the bucket using a permanent marker. Check to see that the water levels within the bucket and the pool water levels outside the bucket are the same as they are. After 24 hours, go back and check the mark. If there is a bigger decrease in the line on the outside of the bucket, this indicates that there is a leak in the pool. This test must be carried out with the pump running and then again with the pump turned off.

  • s3 Find the source of the leak and mark the area. As soon as you realize your pool is losing water, turn off the filtration system and make a note of the point at which the water ceases to be lost. It is necessary to keep water in your vinyl liner pool at all times! If you have a liner pool and the water level is decreasing fast, you should stop this test immediately. To begin, begin adding water and contact a pool specialist
  • A leak in the skimmer or filtration system is most likely the cause of the water coming to a halt at the bottom of the aperture (including the pipes). If you believe that you have a leak in the filtering system, do the following:
  • Make a visual inspection of the water in the return line to determine if there are any air bubbles present when the pool’s pump is working. There is a leak in the suction side of the filter system if this is the case, Check to see that the pump basket lid is securely fastened and that the lid o-ring is lubricated and in excellent working order.
  • If the water comes to a halt at the light, the leak is most likely located in the light housing. If the water level falls below the level of the light, it is possible that there is a leak in the drain at the bottom of the pool. If the pool is losing more water when the pump is working, the leak is likely to be on the return line side of the system, not the supply line side. In this situation, look for flowing water in the waste or backwash line
  • If there is none, turn off the water. You should inspect attentively for anything that seems to be crack, gap, or rip if you feel you have a leak in the skimmer, light, liner, or any other component of the system.
  1. Put a drop or two of dye test solution or a few drops of your pH indicator test reagent at the suspected leak spot to see whether there is any leakage. This should be done with the pump turned off and the water still flowing. Examine the crack, gap, or rip to see if the dye has been sucked into it. Advertisement
  1. 1 Repair any leaks you’ve discovered. Your approach to dealing with the leak will be determined on its location and nature:
  • Identify and fix any leaks that you have discovered. The location and kind of the leak will determine how you handle it.
  • 2 Keep in mind that many leaks will not be identified using the methods outlined above. Calling in a professional is now the best option! Most pool or spa leaks may be identified and repaired without causing significant inconvenience due to the use of cutting-edge technologies.
  • 2 Keep in mind that many leaks will not be identified using the methods outlined above. Calling in a professional is now necessary. Most pool or spa leaks may be identified and fixed without causing significant inconvenience due to the use of cutting-edge technologies
  • 3 Understand the fundamentals of pool plumbing so that you can imagine what a pool technician could do to repair the problem. The plumbing and filtration system for a swimming pool is a straightforward system to design and install. The pool pump is responsible for drawing water through the skimmer and main drains in the swimming pool. In the mechanical room, water goes through a pump strainer basket before being forced through the filter and heater, as well as any additional peripherals such as chlorinators, before being discharged into the atmosphere. The water is finally returned to the pool through the return pipes.
  • Additionally, there are a few extra parts of the swimming pool plumbing system that do not work in a closed (pressurized) system in addition to these closed-system lines. Most swimming pools are equipped with an open system (gravity fed, not pressurized) equalization line, which aids the pool pump in maintaining its prime during periods of low water level in the pool. This equalization line is frequently overlooked or disregarded during restorations, owing to the fact that replacing the line is an expensive and time-consuming undertaking. The equalization line will be connected to the bottom of the skimmer and the other end will be connected to either the main drains or a side port in the pool wall close to the placement of the skimmer, depending on the design of the pool. The line that runs from the bottom of the skimmer all the way down to the main drains is one that is frequently ignored. Nonetheless, because it is not a pressured line, it is more likely to leak than a pressurized line
  • However, on average, this pipe is older than the rest of your pool plumbing system, making it a candidate for unexplained water loss. Because of a variety of factors including pipe material, installation quality, age, layout, and soil conditions, plumbing systems are a persistent source of water leakage. Identifying the source of the leak before tearing apart your plumbing system is essential in determining if the leak is in the plumbing system or the construction of the pool itself.
  1. 4Make certain that the contractor possesses a valid business license. You may find out more by contacting your local town or city’s building department. A trades license is required in some cities and towns. Make certain that you’re speaking with a local contractor or company rather than an online marketing firm. A local contractor will purchase your lead from one of the lead brokers, increasing your overall cost. Advertisement

Create a new question

  • Question I reside in Minnesota, and I just finished winterizing my in-ground pool a few weeks ago. As part of the operation, I covered the pool with plastic. Except for around three feet of water in the deep end of the pool, all of the water has been drained. What should I do in this situation? The leak is most likely located in the line that connects the drain to the skimmer plumbing, which is connected to the water pump. Most likely, the pipe is fractured or broken just where the water level is now at. Before closing the pool, you should have realized that there was so much leaking
  • Question Water is going through the sand filter, which I can hear. What exactly does this mean? You have a broken lateral and a hole will be worn into the filter canister very shortly
  • Question How do I locate a leak in a swimming pool? Use a small amount of color in the water to indicate the direction in which the water is flowing. If water is pouring out, you should be able to detect it very fast
  • Question What is the best way to repair a tiny tear in a vinyl kiddie pool? Order a patch repair kit online or pick one up at the store where you purchased the kiddie pool
  • Questions and Answers In less than 4 hours after I turn on the pump, my water level had dropped by 3 to 4 inches. If I don’t turn it off, the water will continue to rise. What is the best place to begin my search? Take a look at your drain and/or the waste line that leads to your filter valve first. It’s most likely leaking when the pump is operating, therefore inspect it when the pump is running
  • Question What is the best place to look for someone to repair my swimming pool? To find pool repairs in your neighborhood, all you have to do is conduct an online search for them. A number of websites should be available to link you with someone in your local area that can perform the repairs for you. Question Whenever I turn on the filtration system, I notice a tiny quantity of water draining from the waste pipe. Why? It is most likely your spider valve, which is located beneath all of the components that enable you to switch your filter handle to waste, recirculate, bypass, and so on. The valve may not shut completely if this component becomes worn down, allowing water to get through since the seal is no longer intact. Question My hydrostatic valve was changed, and I applied Teflon plumbing tape on the threads, but my pool is losing a lot of water as a result. Do you think it’s feasible that the equalization line is causing the water to leak? Yes. Also look for any other holes or backflow that may be present.

About This Article

Summary of the ArticleXIf you suspect that you have a leak in your swimming pool, inspect the ground surrounding the pool for signs of wetness or sunken areas that may assist you in pinpointing the location of the leak. Pay particular attention to the filter, pump, heater, and pipe valves, since these are the areas where leaks are most likely to occur. When inspecting your vinyl pool liner, look for tears or separations near the fittings, lights, steps, and corners of the pool. You can try turning off the filtration system and looking for a spot where the water stops dropping, or putting 1-2 drops of test dye solution into the water at a suspected leak site and watching to see if the dye is drawn into a crack or gap will help you locate the leak.

Asked in the following category: General The most recent update was made on April 13th, 2020. If you turn off the water to your pool equipment, such as the pumps and filters, and the water continues to leak, it might be a sign of a pressure-side return leak. When the filterpump is running, the piping on the pressure side is put under pressure to prevent a backflow. If you check inside yourpumpbasket, you may see that there is a lot of air coming through the top. If you do not have a pool cover on your home pool, you will lose around 1/4 inch of water level per day or approximately 2 inches per week due to evaporation.

Also, how much water will evaporate from a pool over the course of one day?

This equates to between 2 – 4 inches every week. Water evaporates from a normal-sized pool, resulting in annual water losses ranging from25,000 to50,000 gallons. Furthermore, how can I determine where the leak is coming from in my pool? Symptoms of a Leaking Swimming Pool

  1. The question was submitted to the category of General. The most recent update was made on April 13th, 2019. Having a pressure-side return leak might signal that you have a leak in your pool equipment, such as the pumps and filters, even after turning off the water. If you have a filterpump running, you will see that the pipework on the pressure side is under pressure. In your pumpbasket, you may see a significant amount of air coming through the lid. evaporation alone will result in a loss of around a quarter inch of water level per day or about two inches per week in a household pool without a poolcover Another reason for regular water loss is frequent filter backwashing, which occurs when wastewater from the pool is routed down the drain and into the sewer. Also, how much water will evaporate from a pool over the course of one day is another question. Normal evaporation causes pools to lose between 14 and 12 inches of water per day. There will be between 2 – 4 inches of new growth per week. Due to evaporation, a typical-sized pool will lose between 25,000 and 50,000 gallons of water every year. Furthermore, how can I determine where the leak is coming from in my swimming pool? What to Look for When Your Pool Is Leaking

What exactly is a suction side leak in a swimming pool? The most typical symptom of a suction side air leak is the presence of bubbles, splashing, and foaming in the pump basket. This implies that your pump is not receiving the water it requires to perform properly, but rather that air is entering the system and starving or semi-starving the pump, causing it to fail.

Pool Losing Water Only When Pump Is Running

Allow me to pose this question to you. What if the liner installer just popped out the liner just above the return jet and then turned on the pump to test if water was actually flowing behind the liner rather than back into the pool? Don’t you think that it appears to be a rapid decision for the situation at hand? Perhaps. Despite the fact that I am not an installer, I would think that they could see anything at that time to assist with confirmation. We appreciate you informing us of their response to your warranty repair.

I hope everything goes smoothly and quickly during the repair.

5 Common Causes Of Pool Leaks –

Even if you put up a great deal of effort to keep your pool in good condition, it will ultimately require repairs. With each passing season, your pool is subjected to severe temperatures, extreme weather, and a disproportionate amount of use by the entire family. As a result, it’s inescapable that your pool will begin to leak and require repairs at some point. A leak may be present if you find yourself adding more than a quarter-inch of water per day or more than two inches of water per week to your water supply.

Most of the time, pool leaks are caused by one or more of the following problems:

  • Mechanical problems
  • Structural damage
  • Plumbing problems
  • Broken pipes
  • Loose or broken fittings
  • Electrical problems

Let’s take a closer look at each of these issues so that you can better understand the source of pool leaks. Make sure to contact a professional leak detection firm as soon as you discover any of these issues with your own swimming pool.

Mechanical Issues

If you have an automated fill equipment installed in your pool, a dip in the water level of your pool may not be immediately noticeable. Water costs that are too high, coupled with a constantly shifting chemical balance, may cause a costly “Green Pool” issue characterized by excessive algae development. This might be an indication of a leak problem. If you have a vinyl-lined pool, it’s possible that the source of the leak is the pool skimmer. Fortunately, it is rather simple to locate and repair.

Test this by turning off the pump or closing the skimmer valves and running the pump exclusively on the drainage side of the tank.

Here’s what you need to know about them. Fortunately, tearing up your pool surface and replacing the piping is an extremely unusual occurrence. Among the indications that this is the case are

  • Your pool leaks more when the pump is turned off (since when the pump is turned on, the pool is under a vacuum)
  • Seeing air go into the pump basket is a rewarding experience.

Swimming Pool Leaks: 10 Terrifying Facts You Need to Know

Structural Damage

Structure leaks as a result of structural degradation might occur in any part of your swimming pool. The break in your concrete or fiberglass pool would be the ideal location to look to determine if you are losing water, especially if you can see it. Cracks in your pool are frequently minor and merely aesthetic in nature, which means they are not a safety hazard. However, we urge that you have these fissures corrected as soon as possible. The longer you leave it before repairing them, the worse they will become.

Moreover, leaks are widespread near fixtures such as lights and returns, which makes them a particularly dangerous situation.

If this is the case, you may remedy the situation by sealing the conduit aperture at the rear of the socket using putty or other caulking agents that are acceptable for the pool building material.

It is possible for subsurface leaks to be caused by corrosion or earth movements, which can result in damage to your underground plumbing or even puncture the floor of your pool. If you detect a leak in the plumbing of your swimming pool, call Leak Science immediately. Finding a leak underneath and beneath the decking requires the assistance of a professional who has access to specialist sonar equipment. Furthermore, the longer you wait to repair the leak, the more expensive the damage and water loss will be.

We will replace any flagstone or concrete that we had to remove from your pool, restoring it to its original beauty.

Broken Pipes

Broken pipes rank fourth on our list of the top five most prevalent causes of pool leaks. As a result of the intricate nature of your pool’s plumbing system, leaks can occur in a number of areas throughout the system. This can include things like.


Broken pipes are the fourth most prevalent source of pool leaks, according to our list of the top five reasons for pool leaks. Your pool’s plumbing system is intricate, which unfortunately means that leaks can occur in a number of spots within the pipe structure. Included in this category are the following:


When it comes to discovering leaks in swimming pools, the main drain is one of the most difficult and involved things to determine. It is quite difficult to examine the main drain if you do not have the right skills or equipment since you should not totally empty a pool. Large amounts of water can leak from main drains both within and outside the fixture and via the suction pipe that connects to them.

Aside from that, leaks in the main drain might form in the hydrostatic relief valve as well. This is frequently caused by corrosion or a pebble obstructing the valve’s ability to close completely.


Unfortunately, getting to the connecting point on the underside of a pool skimmer is difficult. Concrete pool skimmers are often enclosed in concrete on all sides, making it even more difficult to locate the connection point without the use of high-tech equipment and well trained hearing. This is why it is so critical to employ a competent leak detection firm to conduct the investigation. The different tests to determine the various causes of leaks can be expensive, and this is all while you are losing water and raising your water bill.


When it comes to older swimming pools, leaks in the equalization pipes are one of the most likely possibilities. When it comes to pools, the equalization line is a non-pressurized pipe that links the main drain to the underside of the pool skimmer. Because it is commonly present in older swimming pools, it is frequently overlooked when substantial restorations are carried out. If you believe you have a leak, contact a reputable leak detection firm straight soon.

Loose or Broken Fittings

While breaks, cracks, or collapses in the pipe might occur anywhere, they are most likely to occur at the points where joint connections have been established. This is a fairly prevalent problem in both pools and spas, and it may be readily resolved if the pool or spa is in an accessible position.

How do I know if my pool is leaking?

Having to deal with leaks on your own is an unpleasant experience. They can be rather prominent and easily identified at times. They can also build up slowly over time, resulting in high water bills and expensive repairs in the long run. Fortunately, there are several symptoms you can check for to determine whether or not your pool has developed a leak.

  • Changes in the water level
  • Wet places in your yard
  • And other issues Water bills that are unusually high
  • Cracks on the surface of your pool or on the pool deck
  • Pool tiles that are loose, fractured, or moving
  • Algae development in the pool
  • Water accumulating under the pool apparatus
  • Pipes that are corroding

5 Common Causes of Pool Leaks

Swimming pools provide much-needed reprieve from the summertime heat while also providing an opportunity to have fun with friends and family members. However, if you own a pool, you are well aware of the amount of maintenance required. In addition to keeping them clean, it is critical to check them for leaks on a regular basis. The sooner you notice indications of deterioration, the better! – Leaks can occur anywhere in your pool and at any time of day or night. You’ll want to find and fix leaks as soon as you can, if at all feasible.

Keep an eye out for any symptoms of damage or the beginnings of a leak.

Pool Leak Detection

The majority of pool leaks do not occur in the subsurface plumbing, despite the fact that it is every pool owner’s worst nightmare to have a giant backhoe come in and rip up the pool deck. It is possible that a leak will develop at a pipe junction beneath the pool deck or beneath the skimmer on occasion, but the repair will almost never need the use of a backhoe. The simplest method of determining whether or not the pipes are leaking is to turn off the pump and stop all of the lines. If it continues to leak, we know it is not the pipes’ fault.

A pool plumbing pressure test may be done on the subsurface plumbing pipes to determine which ones are leaking when the search has been narrowed down.

Experiments can also be conducted to inject air into the pipe, after which experts can listen for the sound of escaping air from an underground leak using headphones and a giant’stethoscope.

Very seldom does a complete run of pipe need to be replaced, and if it did, it would very certainly be abandoned and a new pipe run in its place would be installed.

Leaking Pool Pump!

Pool pumps that leak water on a regular basis are a source of concern even if many thousands of them do so without incident. Even more rarely, a slow drip or constant leak on a pool pump might burst open and drain thousands of gallons from your pool, which is quite dangerous. Swimming pool pumps with leaks can also cause erosion to the equipment pad, and salty or chlorinated water can cause corrosion to the pump motor or the concrete pad beneath the pool equipment pad. Moreover, it is a waste of your heated and treated pool water; thus, even minor pump or filter leaks should be repaired as soon as possible, especially in locations where every drop of water is priceless.

Leaking Pump Shaft Seal

Water leakage along the motor shaft and behind the impeller is prevented by the mechanical shaft seal, which is found on every pool pump. When the shaft seal breaks, water is allowed to flow down the underside of the seal plate and into the hole through which the motor shaft is guided by the shaft seal. Pump seal leaks can be identified by getting down on your hands and knees (with your reading glasses on!) and inspecting the seal plate attentively for water pouring down the rear of the seal plate, as illustrated in the illustration below.

In order to repair a leaking shaft seal, you must first get the proper shaft seal for your particular pump model.

You may also utilize aPump Go-Kit, which comprises the seal, as well as all of the o-rings and gaskets necessary for a certain pool pump model. The following measures should be followed while replacing a shaft seal:

  1. Remove the motor half from the pump housing or volute by unclamping or unbolting it and sliding it out
  2. Removing the diffuser or impeller shroud will make it possible to see the impeller
  3. When unthreading the impeller, maintain a wrench on the back of the motor shaft to prevent it from moving as you unthread it clockwise off the opposite end of the motor shaft. To disassemble the shaft seal, remove both halves from the impeller and the seal plate (the’spring-half’ must be removed first, followed by the ‘donut-half’). Replacing the replacement shaft seal in the same orientation as the old one is critical. Replace the diffuser and worn ring, then bolt or clamp the pump seal plate and housing together securely once more.

Leaking Pump Housing

When your pump’s housing, also known as the volute, is leaking, it means that the pump’s ‘wet end,’ which includes the hairlint pot / strainer basket, and the impeller housing, has developed a leak in one of many places. If the clamp or bolts holding the housing to the seal plate are loose, or if the seal plate o-ring is no longer providing a good seal, the housing may leak where it links to the seal plate, or the ‘dry end’ of your pump. You will also need to repair the pump housing if your pump has suffered freezing damage as illustrated in the illustration above.

Replacement is rather straightforward, requiring only a little amount of light plumbing.

You should drip-drip-drip when the pump is turned off while pulling air into the system when the pump is running if your drain plugs are missing o-rings or were not fitted with Teflon tape.

Leaking Outlet Fitting

It has been stated previously that this may be mistaken for a shaft seal leak in some instances due to the fact that the water runs down the side of the pump and drops over the bottom. If you look closely, you can see where the threaded PVC fitting screws into the output port, where water is leaking. Replacement of the leaky outlet fitting will be required in order to rectify the situation. There is no amount of exterior putty, JB Weld, or any other sealer you may find lying around that will be effective.

For a better seal, you can use apump union with an o-ring instead of a basic MTA fitting and a coupling, as has been done before on this pump seen in the image above.

Using a Schedule 80 nipple or a CPVC pump union, which are both grey in color and temperature resistant, can help to avoid this from happening.

Leaking Inlet Fitting

A shrinking or loose threaded fitting on the inlet side of the pump, where water enters, may suck air into the pump while it is operating and may leak water after the pump is turned off, especially if the pump is placed below the water level. When the pipe is slanted in the image above due to overheating, the threads have melted and shrunk, causing it to leak air and water into the surrounding area. When it comes to outlet fitting leaks, the ideal option is to replace the fitting entirely with a pump union or CPVC fittings rather than Sch 40 PVC fittings.

While the pump is running, apply a thick bead of Pool Putty or Silicone to the inside of the void, allowing it to be sucked into the space.

Leaking Pump Lid

Water will only leak from a leaky pump lid when the pump is turned off or not working, much like the other’suction-side’ leaks mentioned above. If you are only looking for the leak when the pump is working, this might make it difficult to locate the source of the leak. When the pump lids fracture, it may be necessary to repair or replace the pump. On a DynaGlas pump, the pump cover is leaking. Pump lids must be extremely tight, and the o-rings on the pump lids must be oiled. Pump lids that are too loose or that have dried out will nearly always drip a little when the pump is turned off.

The raised edges or notches on many pump lid covers, such as the one seen in the photo above, enable the user to insert a 2×4 piece of wood or a thick piece of steel to be used in loosening an extremely tight lid – or in tightening the lid if that has proven problematic for you.
