In this episode of Turning Leak Detection into Repair Work, we are showing a very quick leak detection finding a skimmer leak using the Pro Complete Leak Detection Kit by LeakTronics on a fiberglass pool in Northridge, CA. Skimmer leaks aren’t uncommon, but lots of times it means a repair or replacement on the skimmer. Ground shifting, pipe damage, cracked plastic – all these are reasons a skimmer might leak, but a proper leak detection will tell you exactly why.

On this job, even though it was initially found that there was a skimmer leak, in the skimmer seam, we kept listening to the rest of the pool to discover if any other leaks were occurring. It’s quite possible that if a pool has aged with time, that a second leak might show in the pool. By listening throughout the entire pool, we are able to hear any leaks using the highly sensitive equipment and powerful LT-1000 Amplifier found in the Pro Complete leak Detection Kit.

Listening and finding leaks is the first part of the leak detection. If we’ve identified leaks in the pool, we then back ourselves up to verify what we heard. This may include static testing, using dye, listening at all returns, lights, drains, side suctions and areas where plastic protrudes through the pool. Once cleared of other leaks, we were left to just hearing the leak at the skimmer.

In the video, you’ll see where we identified the leak at the Skimmer Throat and you can hear the sound that the technician heard suing the PoolScope hydrophone. The sound is similar to, well, almost like a train rushing by. When the pool is quiet, and the equipment is off, the sounds of leaks become very apparent and non-invasively, we can work through the entire pool environment to locate them and prepare to make repairs.

On this fiberglass pool, after finding a skimmer leak, we replaced the skimmer and returned the pool back into service leak free.
