The main drain is one of the most difficult pool leak locations to diagnose because it sits at the deepest point of the pool and connects to plumbing that runs entirely underground. A failed main drain cover gasket, a cracked sump, or a separated joint in the main drain pipe can each cause significant water loss that is nearly impossible to detect without targeted testing. Pipe Leak Detection Pros provides main drain leak detection for residential and commercial pools throughout Sherman Oaks, CA.
Our technicians begin main drain diagnosis with a dye test at the drain cover while the pump is off, observing whether dye is drawn into the drain housing or through any visible gaps around the cover. We follow this with a pressure test of the isolated main drain circuit at the equipment pad to determine whether the pipe itself is holding pressure. If the line fails, acoustic detection equipment is used above the buried pipe path to locate the specific failure point.
Main drain leaks can also introduce air into the system, causing pump cavitation and reduced circulation efficiency — symptoms that pool owners sometimes attribute to equipment malfunction rather than a plumbing defect. Diagnosing and documenting main drain integrity is an important part of any complete pool leak investigation and is a required step before major drain cover upgrades or SVRS (Safety Vacuum Release System) installations.
