Concerned that your pool may be leaking? Water leaks in your pool can cause serious problems. Here are a few tips of how to determine if your swimming pool has a leak and how to fix it. Keep in mind that Inground pools are connected with complex piping and plumbing that may cause leaks that can damage the pool and your property so it is crucial that pool leaks are dealt with in a timely manner. A tip to determine if your pool is leaking is to use the evaporation test. Turn off the auto fill on your pool and mark a line in your pool at the water level. Get a bucket and fill it half way with pool water. Use a permanent marker to mark the water line of the pool water in the bucket. If the bucket of pool water drops the same level as the pool you can conclude that evaporation is causing you to loose water in your pool, not a leak. If the pool water drops faster than the water in the bucket you probably have a leak. You will need to try to locate the leak, start by checking the above ground equipment and the skimmer. Most leaks are caused by cracked skimmers. If the skimmer is cracked, you will need to replace it. If after looking at your above ground equipment and skimmer and you cannot locate the leak, you will need to contact a leak specialist. They will use sonar for underground leak detection. Leak specialists have advance knowledge on the plumbing and pipes of swimming pools and should be able to locate the source of the leak and ways that the leak may be fixed.
