Having a pool is fun but having a leaking pool is not. Water can be lost through evaporation and backwashing, but the result is the same. Leaks cost money and waste energy. Leak detection takes some time and involves a process of elimination by checking the pool lights, shell, plumbing, and equipment.

How to Fix a Leaking Pool?

To make sure that the problem is not evaporation, you first need to conduct a bucket test. Place a half-filled 5-gallon bucket on the first step in the pool and mark the level inside the bucket with tape. Mark the level of the water outside the bucket too and avoid any backwashing or splashing. Water lost from the bucket is evaporation, but any other water loss is evaporation plus a leak.

Vinyl pools are the most vulnerable when it comes to leaking shells but fiberglass and concrete pools can leak this way too. To find leaks in the pool shell, you first need to plug all plumbing lines and shut the pump off. Make sure the water is at a normal level first. Large leaks will drop water levels quickly and will stabilize in the problem area. If the water level continues to drop after lines are all plugged, then you are looking at a plumbing problem. Otherwise, the leak is within the shell, and this can be confirmed by using a dye test. Leaks in the pool lights are more common than people realize. The conduit that carries the light cord can become damaged or cracked when the ground shifts or freezes. If pool water drops below the skimmer and stabilizes at the top of the pool light, this is where your leak is. To fix this, you must seal up the opening where the light cord exits the housing and enters the conduit. Pool putty and silicone are the ideal materials that should be used to repair leaks in the pool lighting.

If all plumbing lines are plugged and you still see water dropping, then you have a plumbing leak. While this may seem like the worst news, most plumbing leaks can be easily fixed. The leak can be identified by a process of elimination. Remember that leaks in the return piping will lose more water when the pump is running and pool suction line leaks will cause more water loss when the pump is off.
Pool equipment leaks are also common, especially in areas of frequently changing climates. Water directly running out of the pump, filter, or heater will be the clearest sign of an equipment leak. When it comes to repairing the leak, you will need to plug the backwash line to stop water flow until you get the replacement parts you need. Most leaking problems can be easily fixed once detected. Plumbing leaks cause the most worry, so if you identify a plumbing problem reach out to an expert. They can help you locate the leak and confirm whether it is a plumbing issue or not. It is important to identify and repair leaks right away because not only do you lose and wastewater, you could also end up with rusted pool walls or erosion.
