Is Your Pool Losing Water? You May Need Some Leak Detection!

To determine if your pool is losing water or if it’s just normal evaporation you can do a simple “bucket test”. Note: If your swimming pool is losing an inch or more a day you may want to skip the bucket test and Call Sparkle Pools ASAP!  This is an indication of a pretty good leak and a large daily water loss.

Here Are Some Indicators That You May Have A Pool Leak:


1.  Filling the pool more than once a week.

2.  Water level regularly falls below skimmers and pump loses prime.

3.  Air bubbles coming out the return jets or air bubbles entering into the pump housing as seen through the clear pump lid.

4.  Swimming pool deck sinking.

5.  Wet spots around swimming pool deck.

Bucket Test Steps:

1.  Make sure water level in pool is at its normal



2.  Get a 5 Gallon Bucket, add weights to the

bucket such as a few softball size rocks and

fill to 3/4 full of water and set on first or second

step in pool.  Make sure bucket is at least 5″-7″

submerged in pool water.


3.  Mark the water level inside the bucket and

the water level of the pool water outside the

bucket.  If the water is not calm, shut the pump

off and wait a few minutes before marking the

outside of the bucket.


4.  After the bucket has been marked, continue with normal pump operation for 24 hours.


5.  After the 24 hour period, compare the water level inside the bucket with the water level outside the bucket in relation to the marks on the bucket.  If water levels inside the bucket and pool water levels outside the bucket are the same in relation 

to the mark on the bucket then only evaporation has occurred.  However, if the pool water level has dropped more from the mark on the outside of the bucket than the mark on the inside of the bucket, it’s a safe bet the pool has a leak somewhere.


6.  Perform a bucket test with the pump running and a bucket test with the pump off. Two separate testsin two different 24 hour periods.  What you are trying to determine is if the leak is in the swimming pool or in the pool plumbing.  A lot of times if there is a crack in a return pipe, the pipe will not lose as much water with the pump off because water pressure has not expanded the pipe or forced the water out as fast.  So doing two bucket test will give some insight into whether you have a static water leak or a pressure side leak.

Normal Evaporation Rates Of 1/8 To 1/4 Inch In A 24 Hour Period Are Normal.

Things That Will Affect Bucket Test:

1.  Rain.  If it rains within the 24 hour period of your bucket test, the test will have to be done again when it’s not raining.

2.  Make sure there are no holes in the bucket you are using for the test.


3.  Auto water fill line not turned off on pool  A lot of times this is over looked.  So make sure if pool is equipped with an auto fill line that it is turned off.


4.  Pets.  Another over looked thing is pets running around the backyard drinking the water out of the test bucket.  Make sure pets are kept away from the pool and the test bucket for 24 hours.
