How Do I Know When I Need Pool Leak Detection?

Pools will naturally lose water due to evaporation, and splashing, and can gain water as well due to rainfall. However, if you notice that you have to add two or more inches of water to your pool per week, you might have a leak. In addition, there are some other signs that you might have a leak. You need to add water more than once a week, your pool has air in the system, the pool deck is sinking or lifting, and/or there are soggy spots around the pool.


All swimming pools, old or new, may develop leaks due to ground movement, improper installation, faulty seals, and a host of other factors. Most people are surprised that a small hole of only 1/8-inch diameter can cause so much water loss, but one inch of water loss per day in a typical 20-foot wide by 30-foot long pool is equal to approximately 370 gallons of water. The longer water is allowed to leak, the greater the chance of major damage (and a high water bill).

How do you find out if you have a leak? A 24-hour measurement (like the Bucket Test) is the best way to determine this. When you are doing this test:

  • Do not swim in pool or use the spa while test is happening.
  • Make sure you test your system in the morning, before your system turns on.
  • If you have an auto fill, turn it off for the test.

Here is how you do the bucket test:

  1. Shut off auto-fill, if on
  2. Fill your pool to the normal level
  3. Mark the water level in the pool inside the skimmer or on the waterline tile.  A #2 pencil will generally do or you can use duct tape.
  4. Next, set a bucket of water on the steps of the pool or spa, leave some of the bucket exposed to catch any rain water.
  5. When the water in the bucket is completely still, mark the water level in the bucket in the same way you did the pool.
  6. Now you’re ready to allow the pool pump to run through its normal cycle.
  7. After 24 hours, and before the system comes on in the morning, compare the water level in the pool to the level in your bucket.

If the water in the pool has lost more than the water in the bucket, then you most likely have a leak and should contact Clearwater Leak Detection!


Pool Leak Detection Service

How can we help? With our specialized equipment, the bucket test is no longer necessary. In about 5 to 20 minutes we can determine if your pool is leaking and also the rate of gallons lost per minute, or inches per day. Equipment like this improves our ability to better diagnose your problem and quickly recheck the pool to see if we have truly fixed the leak – all while we are on site. Our pool leak detection equipment allows us to pinpoint your leak via pressure testing, using a dye list of leak equipment for testing and locating. Our technician is not afraid to get into the pool to make sure all areas that are leaking are identified and/or fixed. Once we have identified where your leak is, we also perform minor leak repair while on site or we can recommend professionals in pool repair.

If you do call for leak repair, please have the following information ready:

  • Is it a pool only or a spa as well?
  • How many gallons is the pool? (Estimate would be Length x Width x Average Depth x 7.5)
  • Is the pools equipment above or below ground?
  • How many pumps are there?
  • Is the pool constructed of fiberglass, gunite, marcite or vinyl?
  • How many skimmers are there?
  • Does it leak more with the filter on or with it off?
  • Are there any fittings in the floor of the pool other than the main drain?
  • How much water does it lose in a 24 hour period?
  • Any other previous leaks? Light, Skimmer, Main Drain, etc.
  • Previous repairs.
  • Installation of new equipment.

One of the first things to do before summertime is to have your pool checked. You can easily perform a pool leak test, but executing the repair should be left to us.

The Steps of Swimming Pool Leak Detection

It’s easy to overlook a minor leak in a pool full of water, until it becomes a daily maintenance. There are several ways to check for a pool leak by the bucket test, pressure testing or gauging the level.
