Leak Detection in Stockton, CA
The most expensive water leaks in a Stockton home are the ones you can’t see. A pipe leaking inside a wall, under a slab, or beneath a yard doesn’t announce itself. It shows up slowly as a higher water bill, a patch of discolored drywall, or a section of flooring that feels soft underfoot. By the time those signs appear, the leak has often been running for weeks or months. Knights Plumbing & Drain uses professional leak detection equipment to find hidden leaks throughout Stockton and San Joaquin County. We locate leaks precisely, without tearing open walls or floors until we know exactly where the source is.

How Knights Detects Leaks in Stockton
We use professional-grade detection equipment to locate leaks without unnecessary demolition. These include electronic leak detection, thermal imaging, and pressure testing. The goal is to give you a precise location and a fixed repair price before any wall, floor, or slab is touched.
Electronic Leak Detection
Sensitive listening equipment picks up the acoustic signature of water escaping under pressure through pipe walls, even through concrete slabs and finished walls. This allows us to pinpoint the leak location before opening anything.
Thermal Imaging
Infrared technology identifies temperature anomalies in walls, floors, and ceilings caused by moisture by mapping where water has traveled, even beyond the immediate leak point.
Pressure Testing
Isolating sections of your plumbing system and testing pressure drop confirms the presence and general location of a leak when other methods need supplementing.

Why Stockton Homes Are Prone to Hidden Leaks
Stockton’s older neighborhoods in Lincoln Village, Del Rio, and Miracle Mile contain homes with original copper and galvanized steel supply lines that have been corroding from the inside after decades of hard water exposure. Pinhole leaks in copper are one of the most common hidden leak causes in Central Valley homes. Galvanized pipes that have scaled and corroded develop small failures at fittings and joints long before they fail catastrophically.
Even newer Stockton homes aren’t immune. PEX connections at manifolds and fittings can develop slow leaks that don’t surface visibly for months. When these small failures suddenly worsen without warning, prompt emergency plumbing response like Burst Pipe Repair in Stockton helps stop active water damage and prevent further structural issues
Upfront Pricing & No Demolition Until We Know Where to Look
You get a fixed price before any plumbing repair begins. We locate the leak first, tell you exactly what’s involved, and give you a clear number before anything is opened up. All work is backed by the Knights Worry-Free Guarantee.
