A homeowner in Clewiston, FL woke up to find her fiberglass pool had lost a foot and a half of water overnight. We found a cracked wall fitting pouring water straight into the ground around the pool.
The Finding
Clewiston is well outside our normal service area, but no other pool leak detection company would make the trip, so we did. The homeowner's fiberglass pool was losing water so fast she couldn't keep it filled, and she was worried about the pump running dry.
Using the H.U.N.T.E.R. Method, we checked the fiberglass shell, fittings, and plumbing systematically. We found the source: a cracked wall fitting, the part in the pool wall where water returns or lights and other features connect. The crack was letting water pour directly into the surrounding ground, which is why the pool was dropping 18 inches a day.
Broken wall fitting found in fiberglass pool, confirmed as the source of the 18-inch daily water loss.
What We Did
We applied an emergency patch on the spot to stop the water loss immediately. The permanent repair, removing the broken fitting, prepping the fiberglass surface, and installing a new fitting, will follow on a return visit.
Fiberglass Pools Need a Different Approach
Fiberglass pool leak detection has to account for construction that's different from concrete or vinyl liner pools. Cracked wall fittings, like this one, are one of the most common sources we find on fiberglass pools, along with damaged skimmers, pool lights, shell cracks, and plumbing line breaks.
