Sonic Leak Detection is used in conjunction with Pressure Testing for finding leaks in your plumbing. It is used to listen for escaping air or water from the pipes that run under your decking. It will not find leaks in your liner as some will have you believe. We can find leaks in your lines quickly and accurately using this test. We also have certified divers ready to tackle any minor underwater repair fast and efficiently, without the need to drain your pool, and the crew and experience to fix any leak.
