This indicated that we should suspect suction side plumbing. Since the pool water level was already below the skimmers we dove down to check the main drains. A dye test confirmed that the main drain line was drawing dye from both of the two main drains.<\/p>\n<p><iframe loading=\"lazy\" src=\"https:\/\/www.youtube.com\/embed\/vScCWaPY6R8\" width=\"560\" height=\"315\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/p>\n<p>We set up our\u00a0<a href=\"https:\/\/www.leaktools.com\/pressure-testing.html\">pressure\u00a0testing equipment<\/a>\u00a0to start pinpointing the location of the leak and ran a quick pressure test with water first to confirm that what the dye was showing was accurate. Once we started inducing air and purged all the water from the line we were able to hear a good leak noise in two spots with the\u00a0<a href=\"https:\/\/www.leaktools.com\/hydrophones-and-adapters.html\">Hydrophone<\/a>\u00a0(attached to the\u00a0<a href=\"https:\/\/www.leaktools.com\/xlt30h-electronic-listening-device.html\">XLT30H<\/a>). The first noise was right at one of the main drain bowls and the other was in a corner of the pool. While we had the main drain lines plugged we also ran another\u00a0<a href=\"https:\/\/www.leaktools.com\/the-leakalyzer.html\">Leakalyzer<\/a>\u00a0test, which verified the water loss had stopped in the pool so there was no need to run a LeakTrac on the liner or dye test the fittings, skimmers, etc.<\/p>\n<p><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter size-large wp-image-1246\" src=\"https:\/\/www.leaktools.com\/blog\/wp-content\/uploads\/2019\/03\/HydrophoneXLT30_web-640x401.jpg\" alt=\"\" width=\"474\" height=\"297\" srcset=\"https:\/\/www.leaktools.com\/blog\/wp-content\/uploads\/2019\/03\/HydrophoneXLT30_web-640x401.jpg 640w, https:\/\/www.leaktools.com\/blog\/wp-content\/uploads\/2019\/03\/HydrophoneXLT30_web-150x94.jpg 150w, https:\/\/www.leaktools.com\/blog\/wp-content\/uploads\/2019\/03\/HydrophoneXLT30_web-300x188.jpg 300w, https:\/\/www.leaktools.com\/blog\/wp-content\/uploads\/2019\/03\/HydrophoneXLT30_web-768x481.jpg 768w, https:\/\/www.leaktools.com\/blog\/wp-content\/uploads\/2019\/03\/HydrophoneXLT30_web.jpg 883w\" sizes=\"(max-width: 474px) 100vw, 474px\" \/><\/p>\n<p>In order to determine which noise we were hearing was actually the leak, we slid an <a href=\"https:\/\/www.leaktools.com\/inflatable-plugs.html\">inflatable plug<\/a> 8\u2019 into the line from the main drain bowl and re-pressure tested. The pressure test still failed, so we knew the leak had to be farther than 8\u2019 away from the main drain bowl. With this information we decided that the place we heard noise in the corner of the pool was the leak location. Another confirming factor was that while we were inducing air, there would occasionally be a bubble that came up\u00a0behind the\u00a0liner to the surface of the pool. Before leaving we also ran pressure tests on skimmer and returns to verify the rest of the plumbing was good.<\/p>\n<p><strong>Learnings:<\/strong><\/p>\n<ol>\n<li>Pressure testing helped us identify actual problem when the\u00a0 noise was heard in multiple locations.<\/li>\n<li><a href=\"https:\/\/www.leaktools.com\/the-leakalyzer.html\">Leakalyzer<\/a> verified that pool shell was leak free, saving us time during the isolation phase.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"<p>Type of Pool: Vinyl Liner Equipment Used: Leakalyzer, Pressure Testing Equipment, XLT30H,\u00a0Hydrophone,\u00a0 Dye Situation: Customer reported that the pool was leaking 1-2 inches per day and that a new liner was installed recently.
