The first step in successful leak detection is to gather information. Before calling JJM, find answers to the following questions:

How many inches of water is the pool losing over a 24-hour period?

Are there any visible cracks in the pool?

Are there any wet spots around the pool deck or around the pool area, such as constantly wet parking lots or wet spots in the grass?

Has there been any recent construction activity?

Does the pool have any in-floor cleaners, waterfalls, or fountains?

Could the loss of water be due to evaporation?

Once we arrive we will perform a complete pressure test of all underground plumbing to confirm that the leak is located on the underground plumbing. Each line will be tested individually at 20 PSI.
Pressure testing is a very time and labor-consuming test. Pressure test usually requires cutting some part of filter plumbing to install the pressure testing plugs or bypassing filters and motors that could affect testing results.

Suppose the pressure test confirms that the leak is located in the underground plumbing. In that case, our service technicians will pinpoint the exact location of the leak with our high-resolution underground sonic leak detection equipment.

JJM Pool Division has years of extensive experience in various leak repairs. A leak in the underground plumbing is usually the worst scenario for the pool owner. It will require excavating the pool deck or pool shell around the leak and replacing part of the underground plumbing. Leaks caused by structural cracks in the pool shell do not require excavation.
