Swimming pool Leak detection in Los Angeles


Southern California next to Arizona is an excellent place to own a swimming pool. Once installed, however, swimming pools are not without issues. With seismic activity, unstable soil conditions coupled with age, pool leaking is unfortunately commonplace her in Los Angeles.¬†Swimming pool Leak detection is a necessary component to determining if water loss is typical or otherwise atypical. A DIY pool leak test such as a bucket test is in our opinion, a good first step in determining where the water leaving the pool is via the sky, or the soil first step. ¬†Bucket tests are great not because it’s the cheapest way to go… but because you will rule out swimming pool leak verses evaporation fairly quickly and for the cost of one bucket.

Leak Detection Facts

  • 95% of all swimming pool and spa leaks are within a 3ft radius of the pool or spa itself
  • 12% of all new pools leak
  • 65% of all swimming pools leak within their first 20 years
  • 15% of all complete remodel jobs will leak
  • 5% of all swimming pools in total have a leak that has gone undetected (accidentally or purposefully)

Swimming pool Leak vs Evaporation

Swimming pool Leak vs Evaporation

Water loss comes in many different forms. What isn acceptable amount of water loss for a pool in Southern California? To answer this we need to first understand that water loss it typical. As a matter of fact, it’s expected. As pool professionals we see an average of quarter inch (1/4″) of water loss due to evaporation each day? For the most part, the determining factor in how much or how little swimming pool water loss is to be expected greatly depends on the climate. Things such as wind, sunlight and the humidity will greatly determine the average evaporative water loss.

On the other hand, leaking within the swimming pool is a whole other condition. There is no average to speak of when it comes to water loss due to the pool leaking. Anything over that 1/4″ average, we suggest you have someone take a look at the pool. Although a 1/4″ is considered typical, we’ve seen leaking up to and exceeding 3″ in a single day. As a matter of fact, I’ve actually heard of pools leaking even more than that.

First thing you will want to do if you suspect a pool leakis to perform a DIY do it yourself pool leak test or, the bucket test. Essentially, the DIY bucket test will rule out typical evaporation vs an actual leak. if anything, this test will provide a much needed baseline so when you hire a leak detection specialists, they will have more information than just, ” I think it leaks”.

Older Los Angeles Pool Leaking


Aging pools have aging issues. Pool piping, connections, interior finish, shell are all susceptible to age and thus deterioration. Not all old pools leak. Nor is it safe to assume new pools do not leak. In a word deterioration… it’s the second most common cause of leaking within pools and spas second to shoddy construction. It’s not safe to assume that all old pools leak, nor is it safe to assume that all new pools are intact water tight either.

Age plays in a huge role in how the underground piping as well as the pool body itself performs over time. Take the pool piping for example. Many years ago all pool pipes were all made of copper, installed underground. Back then there was no data on the longevity of copper piping exposed to the earth over long periods of time, like there is today. The result is a material which deteriorates, and leaks.

Another example is the skimmer. Back in the day, skimmers were made of concrete and then metal. Unlike the skimmers today which are plastic. These older versions of skimmers were susceptible to deterioration and thus leaking.

DIY Pool Leak Tests

The easiest way to rule out the possibility of evaporation rather than a pool leak is to first perform a simple bucket test. This test is very easy to perform and can be accomplished with a simple 5 gallon bucket.

Bucket Test Procedure:

  1. Bring the pools water to its normal level first.
  2. Turn off the auto fill device if you have one.
  3. Place the bucket on the first step. You may want o place a heavy object like a brick inside to keep the bucket stable.
  4. Fill the bucket as close to the top as possible. This is because we want the air to move across the bucket just as it will over the pools surface.
  5. Mark the water level inside the bucket.
  6. Mark the pools water level outside the bucket.
  7. Compare after 24 hours. Do not wait longer than 24 hours though.
  8. If there is a significant difference in the two water levels, you may have a leak.
  9. Re test the pool again but this time, leave the equipment off and compare those results.
