If your pool has a crack in it, it will leak. This is a big deal, as water can affect the soil beneath the pool, causing it to shift. In turn, this leads to even more cracks in your pool. Depending on where your pool is situated, a pool leak can also drain toward your home, causing foundation problems. Finally, pool leaks can affect the plumbing underneath your pool, shortening the lifespan of pipes and fittings. Unfortunately, since you cannot see under your pool, it can be hard to determine if your pool is leaking. Here are a few of the most common signs that are indicative of a pool leak.
You Are Using More Water in Your Pool
One of the most common signs that indicates you may have a pool leak is using more water in your pool. If you feel like you are filling your pool up more often than you normally do, you may have a pool leak. If your pool self-fills, look at your water bill to see if you are using more water. When possible, compare your water usage to past summers to see if you are using more water.
You Notice Cracking Around the Pool Deck
Another sign of a potential pool leak is cracking around the pool deck. As water leaks from the pool, the ground and soil beneath the pool begin to erode away, which can cause the concrete pool deck or apron to shift and move. In turn, you may see cracks around the pool deck.
Your Pool Has Failed the Cup Pool Leak Detection Test
The final sign of a pool leak is failing a cup or bowl pool leak detection test. It is recommended that every pool owner conduct this test on their own at the start of pool season and the end to check for potential leaks. Simply select a bowl or cup that is larger than the depth of your pool and place it on the first or second step. Fill it so the water in the bowl or cup is level with the water level in your pool. The water in the bowl or cup should evaporate at the same rate, if not slightly faster, than the water in the pool. If the pool level drops below the level of the water in the bowl or cup, you likely have a pool leak. This test should be done on a day no one is using the pool to ensure splashing doesn't account for the water loss.
If you suspect you have a pool leak, it is important to contact a swimming pool professional to test for a pool leak and find out where the leak is. This process is commonly referred to as pool leak detection. Detecting if there is a leak and where it is can help a pool repair company determine the best way to repair the problem before more damage is done. Contact a company as soon as possible if you suspect you may have a pool leak.
