Advanced Leak Detection in Sonoma County
Water leaks behind walls, under slabs, and inside ceilings can go undetected for months while silently causing rot, mold, and structural damage. Action Plumbing uses electronic listening devices and thermal imaging techniques to locate leaks accurately — often without opening a single wall.
Types of Leaks We Find & Fix
- Slab leaks — pipes beneath your concrete foundation
- Hidden wall leaks — pinhole leaks in copper or galvanized pipe
- Under-slab drain leaks
- Pool line leaks
- Irrigation and supply line leaks
- Water main leaks between meter and house
Slab Leak Warning Signs
- Water bill suddenly spikes with no obvious cause
- Warm or hot spot on your floor (hot water line leak)
- Sound of water running when all fixtures are off
- Cracks appearing in floors or walls
- Mold or mildew smell coming from floors
- Low water pressure throughout home
