How To Find And Fix Pool Leaks?

Having a pool is fun but not when it has a leak. Leaks can be a danger and very expensive if not corrected in time. Leaks cost money and waste energy. Leak detection takes some time, especially if you are not sure what part of the pool is leaking. To identify a leak you need a process of elimination by checking the pool lights, shell, plumbing, and equipment. To make sure that the problem is not evaporation, you should conduct a standard bucket test. Place a half-filled 5-gallon bucket on the first step or rung of the ladder and mark the level inside the bucket with tape or waterproof marker. Mark the level of the water outside the bucket as well and avoid any backwashing or splashing. Any water lost from the bucket will be evaporation, but any other water loss noticed will be regular evaporation plus a leak.

Finding and Fixing Pool Leaks

All pools are susceptible to leaks, but vinyl pools are the most vulnerable. To find leaks in your pool shell, you first need to plug all plumbing lines and turn off the pump. Large leaks will drop water levels quickly and then will stabilize in the problem area. If the lines are all plugged and water continues to drop then you likely have a plumbing problem. If not, the leak is probably in the pool shell and you can confirm with a standard dye test.  Leaks in the pool lights are much more common than people realize. The conduit that carries the light cord is easily damaged whenever the ground shifts or freezes. If pool water drops below the skimmer and stabilizes at the top of the pool light, this will confirm that the leak is in the pool light system. To repair a leak in this area, you need to seal up the opening where the light cord exits the housing and enters the conduit using pool putty and silicone.

Searching for pool leaks

If all plumbing lines are plugged and water levels are still dropping, then you have a plumbing leak. While this may seem like the worst news, most plumbing leaks can be easily fixed so long as they are caught early enough. The leak can be identified by a process of elimination. Start with the return piping as this is a more common place for leaks, and more water will be lost when the pump is running. A leak in the pool suction line will cause more water loss when the pump is off.

Pool equipment leaks are also common, especially in areas of frequently changing climates. Freezing conditions, as well as humidity, can interfere with mechanics and equipment. Water directly running out of the pump, filter, or heater will be the clearest sign of an equipment leak in that specific component. To repair any equipment leak, you will need to plug the backwash line first in order to stop water flow until you get the replacement parts you need.
Most leaking problems can be easily fixed once detected. Plumbing leaks can be the most expensive to repair and cause the most damage if not repaired right away. If you identify or suspect a plumbing problem you are advised to reach out to an expert. They can effectively locate the leak and confirm whether it is a plumbing issue or not. It is important to identify and repair leaks right away to prevent wasting water, and to prevent any rust and erosion that excess water can cause to the pool and equipment.


Your pool is more than a fun place to hang out and relax. It is an investment that can add value to your home. Leaks can cost money by wasting water and can cause expensive damage if left untreated.
