Leak Detection Services
Leak Detection in the San Fernando Valley
Non-invasive leak detection for slab leaks, hidden pipe leaks, and water line issues. We find the leak before recommending a repair — so you know exactly what you are dealing with.
Professional leak detection that protects your home
A hidden water leak can cause serious damage long before it becomes visible. All Plumbing Services uses professional leak detection equipment to locate slab leaks, underground pipe leaks, and concealed water line failures without unnecessary demolition. We pinpoint the source first, then give you a clear picture of your repair options.
Leak detection and repair services
Slab leak detection
Pressurized water lines running beneath your concrete slab can develop pinhole leaks that go undetected for months. We use electronic listening equipment and pressure testing to locate slab leaks precisely.
Electronic leak detection
Acoustic listening devices and electronic amplification let us hear water escaping from pipes inside walls, under floors, and underground — without opening up your home.
Water line leak detection
Main water line leaks between the meter and your home can waste thousands of gallons and drive up your bill. We trace the line and isolate the leak location before any digging begins.
Underground pipe leak detection
Buried supply and drain lines can crack or corrode over time. We use pressure testing and ground-level detection equipment to find underground leaks without excavating your yard.
In-wall leak detection
Leaks inside walls from supply lines, shower valves, or drain connections are located using moisture meters and acoustic equipment so we open only what needs to be opened.
Slab leak repair
Once the leak is located, we offer repair options including spot repair, pipe rerouting, and full repipe — and we explain the trade-offs of each before any work begins.
Pressure testing
Pressure testing isolates sections of your plumbing system to confirm whether a leak is present and narrow down its location before we deploy detection equipment.
Camera inspection
After locating a leak, a sewer or pipe camera inspection can reveal the condition of surrounding pipe — helping us recommend the right repair rather than a temporary fix.
Camera inspection after every leak detection
Once we locate a leak, we often recommend a camera inspection of the surrounding pipe to assess its overall condition. A single repaired leak in a deteriorating line can be followed by another failure nearby. Camera inspection lets us give you the full picture so you can make an informed decision about repair versus repipe.
