I suppose it would depend on the company, but I can tell you that around here, they act like you're nuts if you ask them to find a liner leak. I called one of the two really reputable companies here, and they kept insisting that they couldn't guarantee that they'd find anything. When the guy got to the house, he kept saying that he REALLY thought it was the gasket behind the liner at the light fixture--I knew better, but the pool is 10 years old, so I figured a new gasket and him shutting up would be good enough for me, and I would wait for ALD.Originally Posted by Jeffski
The guys from American Leak Detection bring a weight to hold them under, a breathing apparatus, a syringe with yellow dye, and goggles. (Also a wet suit, if the water's cold.) They seem to really know what they're looking for, and can find them in no time.
If you can snorkel or scuba--in other words, if you can make yourself inhale while underwater--you can quickly find your own liner leak in warm water. Sure wish I could do it!
Do a test: call your pool builder and pretend to be an average Joe pool owner who has a liner leak. See what they say. Make sure you explain that the water has leaked down below all fixtures--say there is only 12 inches of water left in the pool. Their response to this will tell you a LOT.
