Leak Detection in Lathrop, CA
Hidden leaks in Lathrop homes and commercial properties don’t announce themselves. Instead, they accumulate. A slow leak under a slab or inside a wall runs undetected for weeks while water bills skyrocket, building materials absorb moisture, and mold begins establishing itself in spaces no one ever looks at. Knights Plumbing & Drain locates hidden leaks throughout Lathrop and San Joaquin County using professional detection equipment. We find the source precisely before recommending any repair, so you will not pay for exploratory demolition.
Call (209)-319-1703 to schedule your leak detection appointment.

Our Leak Detection Techniques
Thermal Imaging
Infrared cameras identify temperature anomalies in walls, floors, and ceilings caused by moisture. They reveal both the leak point and the extent of water migration within the structure.
Electronic Acoustic Detection
Professional-grade listening devices pick up the acoustic signature of water escaping under pressure through concrete slabs, finished walls, and underground line runs. We locate the leak without opening surfaces until we know precisely where to look.
Pressure Testing
Systematic pressure testing isolates sections of the plumbing system to confirm the presence of leaks and narrow the location when used alongside acoustic and thermal methods.
Lathrop's Leak Risk Profile
Lathrop’s newer construction gives many homeowners a false sense of security. Modern PEX plumbing is durable, but connection points at manifolds and fittings can develop slow leaks if the installation wasn’t to standard during construction. These leaks often go undetected for extended periods because they’re small, located in walls or under slabs, and don’t cause obvious visible damage early on.
Older Lathrop properties face the harder version of the problem: aging supply lines running through clay-heavy soil that shifts seasonally, creating mechanical stress on joints and fittings that eventually results in failure. San Joaquin County’s hard water accelerates internal pipe corrosion, making pinhole leaks in copper lines a consistent finding in leak detection calls throughout the area.
Fixed Price. No Surprises
Your Lathrop plumber starts by finding the leak. You receive a precise location and a fixed repair price before any surface is opened. All services are backed by the Knights Worry-Free Guarantee.
