Professional Leak Detection for Water Supply Lines
A leaking water line can cause low pressure, higher utility bills, surface damage, and water loss inside or outside the property. We diagnose leaks in interior supply piping, main service lines, and other pressurized water lines so the repair can be based on evidence instead of guesswork.
Finding Leaks in Pressurized Water Piping
Water-line leaks may develop at fittings, valves, joints, or damaged sections of pipe. The line may be visible and accessible, or it may run behind a wall, beneath a slab, through a ceiling, or underground between the meter and the building.
We begin by confirming water loss and checking accessible plumbing. Depending on the system, we may isolate sections, monitor the meter, perform pressure testing, trace the line, and use acoustic or thermal equipment. After locating the likely source, we explain the findings and discuss repair or replacement options.

How We Locate the Problem
- Verify the leak symptoms and inspect fixtures, valves, and accessible piping.
- Determine which section of the water system is likely affected.
- Use appropriate pressure, meter, acoustic, tracing, or thermal tests.
- Identify the suspected location and review repair or replacement choices.
California Code and Permit Considerations
A confirmed water-line repair affects potable-water service or distribution piping. The completed work should use approved materials and fittings and address potable-water protection, valves, joints, support, pressure testing, flushing or disinfection when applicable, and required inspection.
Elk Grove lists water-line repairs and replacements as minor-permit work, and Sacramento provides a minor-permit pathway for water-service and other residential plumbing scopes. The exact requirement should be verified for the property address and repair plan.
