Though pools naturally lose water due to evaporation, to water splashing out (during pool use) or to excessive filter backwashing, these occurrences can never be done away with. If lost water necessitates you to add more than two inches of water into your pool every week, though, then it may be likely that it has a leak.

Watertight. This is how pools are meant to be. Sealants, however, eventually deteriorate while other parts of the pool, including the shell, the plumbing system and its fittings or accessories, just wear out. If there is a leak, it is very important to repair it as this will not only save water, chemicals, and heat, but also prevent the washing away of fill dirt and the weakening of a pool’s structural components.

Determining if your pool has a leak or if you are just losing water due to evaporation is not as easy as it seems. While, on average, a pool loses about a quarter of an inch of water every day, rate of water loss can drastically change due to variations in humidity, wind intensity and sunlight. One way to determine the cause of water loss in your pool is through the Bucket Test. This test requires the following steps:

1. Bring the pool water to normal level. Fill a 5-gallon bucket with pool water to approximately 2″ from the top.
2. Place the bucket on the first or second step of the pool. Ensure the bucket is immersed in the pool at least five inches.
3. Mark the water level inside the bucket.
4. Shut off the pump and auto fill and mark the pool water level on the outside of the bucket.
5. Resume normal pool pump operation.
6. After 24 hours, compare the two water levels. If the pool water (outside mark) goes down more than the bucket’s water level, there is probably a leak. If levels are the same, only evaporation has occurred. (

If, through this test, you find out that your pool has a leak, then you need to realize that a leak can be destructive; it can also cost you hundreds of dollars every day. Thus, save your pool and yourself from all the trouble and costs associated with a leaking pool; maybe it is time to call the experts.
