Type of Pool:<\/strong><\/p>\n

Vinyl Liner<\/p>\n

Equipment Used:<\/strong><\/p>\n

Leakalyzer<\/a>, LeakTrac<\/a>, Dye Tester Cones<\/a>, Pressure Testing Equipment<\/a>, Electronic Listening Device,<\/a> Hydrophone<\/a>, Tube Level<\/p>\n

Situation:<\/strong><\/p>\n

We were called to examine a new build that was losing 4\u201d of water per day. It hadn\u2019t been leaking for the first four days that it was filled but recently started rapidly losing water. When we arrived to the pool the water level was down below the skimmers, but the skimmer bowls were still full of water \u2013 indicating that those lines were not leaking.<\/p>\n

Solution:<\/strong><\/p>\n

Suspecting that the problem was in a plumbing line, we did a quick dye test of the returns and cleaner line with the dye testing cones<\/a>, but they also were not drawing water. Our Leakalyzer<\/a> test had been running during these initial observations, and indicated a loss of 3.5 inches per day. A quick scan with the LeakTrac<\/a>\u00a0showed no leaks in the liner, so it was time to dive down to the main drain. A dye test with the dye testing cones<\/a> showed that line was the source of our water loss.<\/p>\n

We then plugged the main drain lines while we were diving and ran a pressure test<\/a> from the equipment back to the pool. The water pressure test confirmed the line was leaking, so we then started inducing air for sonic location. It took a while for the air to reach the leak, indicating that the leak wasn\u2019t close to the equipment where the air was being induced. So, we used a hydrophone<\/a> attached to our XLT30H listening device<\/a> to start listening along the main drain lines where they ran close to the shell of the pool. We could hear the loud bubbling\/gurgling noise of air escaping into water saturated soil near the base of the wall in the middle of the deep end.<\/p>\n
