If you hear water running when fixtures are off, see your water bill climb, notice warm or wet areas on the floor, or suspect a hidden plumbing leak beneath the slab, Leak Tech LLC can test the system and pinpoint the source before unnecessary concrete or flooring is opened.

We isolate the suspected plumbing and pressure test the line to confirm whether it is actually losing pressure. This separates a real plumbing leak from unrelated water use or surface moisture.
Hot and cold water lines are isolated as needed so the leak can be narrowed to the affected section of the plumbing system instead of guessing where the problem is.
Sensitive acoustic equipment is used to listen for the sound created by escaping water or air beneath the slab and help narrow the leak to a smaller search area.
Once the test results point to the leak area, we mark the location and explain what was found before any access or repair work begins.

We explain the test results and the identified leak location so the property owner understands what was found and what the next repair step is.
A slab leak is a water-line leak beneath or within the concrete foundation. Because the pipe is hidden, the first sign is often not visible water. Many homeowners first notice a higher water bill, a meter that continues to move, warm flooring from a hot-water leak, or the sound of water when nothing is running.
Opening the wrong area can create unnecessary damage and cost. A proper slab leak inspection is designed to confirm which line is leaking and narrow the source before flooring, tile, or concrete is removed. Leak Tech LLC focuses on testing first, then opening only the area that makes sense based on the findings.
The same company that locates the leak can also perform the plumbing repair. This keeps the diagnosis and repair under one scope, reduces confusion between separate contractors, and gives you one team responsible for explaining what was found and how it will be repaired.
Leak Tech LLC provides professional slab leak detection and plumbing repair throughout the Phoenix metro area. If you suspect a hidden leak under the slab, schedule an inspection so the plumbing can be tested and the leak location identified before the problem causes additional water loss or property damage.
Get the plumbing tested and the leak area identified before the problem causes more water loss or unnecessary damage.
