How to: Swimming Pool Leak Detection


If you happen to notice that the water level in your pool has decreased, the first thing you want to make sure of is if any leaks are causing it. 

When you notice that the water level in your pool has decreased, you’ll want to make sure a leak does not cause it. First thing to check if you have a leak is to do a bucket test. This is when you fill a five-gallon bucket with at least three inches of pool water, place the bucket on the first step of your pool (do not immerse the bucket), wait 24 hours if you notice that the level of the pool has lowered more than the bucket, chances are you have a leak. If the test proves you may have a leak, then it’s time for you to call the professionals. Here are some areas you could be experiencing the leak from:

Plumbing Lines

Once you have hired a professional pool leak detection plumber, they will inspect your pool’s extensive plumbing system. Our technicians at Plumbing Utah Heating & Air use a complex ultrasound system that pinpoints any cracks or tears in the intake or return lines of your pool. Usually, another clear sign that you have a leak is if there’s water on the pump room floor. This means you have a broken line or a loose fitting that leads to the filtration system. PVC piping is commonly used in pool plumbing. While PVC is durable, it can develop tiny cracks that could eventually lead to bigger tears if left unrepaired. A break in your pipes or lines can cause leaks and the pool will not fill, it could also allow dirt to enter the pool.

Pool Shell

Pools have a gunite or concrete shell that can crack. The plaster coating of these materials can peel or wear down with time. These small cracks can grow and lead to a leak. In these situations, our technicians at Plumbing Utah use red dye in swimming pool leak detection. The dye is drained through the leak, allowing our technicians to detect the leak. Afterwhich, an underwater safe epoxy is used to fill and seal these cracks. Our technicians also inspect all fitting and corners for leaks and cracks if your shell looks damaged. Another common problem area is the area where the skimmer is attached. 

Vinyl pools are prone to stretching and tearing around the area where the frame is attached. Fiberglass pool shells don’t often crack unless they sustained some heavy impact. For these pools, any fittings, including ladders and drains, should be checked regularly.
