How do you find a leak in a pool? If you are thinking you want to find the leak yourself instead of hiring a pool leak detection company to come out and look for it this video will help you to understand the first steps that you should be taking. Most leak detection companies offer locating services not repair services so finding the leak is only the first part of the leak detection and repair process. It will not hurt anything for you to attempt to isolate and find the leak for yourself first before you call in the professionals.
Through some simple tests you can very likely determine whether the leak exists in the plumbing system for the pool, or within the pool structure itself. You will also likely be able to estimate the amount of unexpected water loss you are experiencing daily. Right away this is enough information that start making more informed guesses as to where the pool is potentially leaking and where you should focusing your efforts on looking.
The most common leak locations for swimming pools - Pools tend to leak in predictable ways and this can help you focus on where you should be looking for the leak in your pool. Plumbing system leaks can be determined by seeing if the pump running affects the rate of water loss in the pool. It won't with any kind of structure leak. If a plumbing leak is suspected then a suction side leak would allow air into the pump chamber and should be easily visible that the pump is drawing air on the suction side. Likely the pump could be hard to prime for this reason. If the leak is on the pressure side quite often you will see air bubbles returning to the pool through the return connected to the problem pipe. The point where the return pipe connects to the pool wall is always a high potential for leaks due to any movement in the ground causing a leverage point where the pipe meets the wall. Pipe inspection cameras are helpful for locating leaks like this. Suction side leaks will often be at the skimmer body connection. Skimmers could be ABS but they can also be PVC. Some have threaded connection ports and some are solvent cement welded. If a technical error is made with connection materials, solvent cement, thread sealants or any other problems during installation you can develop leaks at the skimmer connection point long in the future. Pool structure leaks could be cracks or holes in the interior surface for vinyl pools, concrete pools and fiberglass pools. Light niche failures are very common and one of the most likely places to look for a structure leak in a pool, especially the point where the wires exit the light niche.
First steps for finding leaks in pools - You need to perform the bucket test and monitor your pool water level in relation to a known sealed vessel like a plastic bucket. Both should evaporate at the same rate. If the pool loses water faster than the bucket, you have a leak in your pool. If tuning the pump on or off affects the rate of water loss over 24 hours in any way this indicates the plumbing system is likely where the leak is. If the pump changing on or off has zero effect on the rate of water loss, likely the leak would be somewhere within the structure of the pool itself.
