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

Vinyl \/ In-ground<\/p>\n

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

Leakalyzer<\/a>, XLT30H<\/a> Bigfoot and Ground Probes, Hydrophone<\/a>, Pressure Testing Kit<\/a>, Dye<\/a><\/p>\n

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

We received a call about a pool that had just had a new liner installed, but was still losing lots of water. The customer suspected the water loss was in the main drain line. When we arrived to the pool the Leakalyzer<\/a> confirmed the reported water loss.<\/p>\n

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

The main drain lines were plumbed separately up to\u00a0the equipment, so we put an open plug in each of the main drains to see if they would draw dye. One line did, but the other did not. To confirm, we pressure tested the line that drew dye with water and it failed. In order to pinpoint the exact location of the leak, we then induced air into the line and began to listen with the hydrophone for a leak under the pool, but didn\u2019t hear any significant noises. We then switched to using the Bigfoot microphone with the XLT30H<\/a> to listen through the concrete around the pool and still didn\u2019t hear anything that\u00a0indicated the leak location. Only when we started using the XLT30H<\/a> ground probes in the soil between the pool deck and the equipment were we able to get close enough to the leak to pick up a great noise and find the exact location of the leak.<\/p>\n
