How We Find Slab Leaks

Pressure Testing

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.

Line Isolation

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.

Electronic Listening

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.

Pinpoint & Mark

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.

Restored After Repair

When access requires opening concrete, flooring, or surrounding finishes, Leak Tech LLC restores the repair area as closely as reasonably possible to its original appearance.

Detection Fee Applied to Repair

When Leak Tech LLC performs the slab leak repair, the slab leak detection fee is applied as a credit toward the repair.

1-Year Repair Warranty

Leak Tech LLC slab leak repairs include a one-year warranty on the completed repair workmanship.

Slab Leak Questions Homeowners Ask Most

How do I know if I may have a slab leak?

Common warning signs include an unexplained high water bill, a water meter that keeps moving when fixtures are off, the sound of running water, warm areas on the floor, wet flooring or carpet, low water pressure, or water appearing near the foundation.

Do you have to break concrete to find the leak?

No. The goal of leak detection is to confirm and narrow the leak location before access is opened. Pressure testing, line isolation, tracing, and electronic listening are used first.

Can Leak Tech LLC repair the leak after locating it?

Yes. Leak Tech LLC is a licensed Arizona plumbing contractor and can handle both slab leak detection and the plumbing repair under AZ ROC #360185.

What repair options are available?

Depending on the leak location and condition of the plumbing, options may include direct access repair, rerouting or bypassing a line, or replacing a larger affected section.

Do you provide documentation of the finding?

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.

Common Signs of a Slab Leak in Phoenix Homes

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.

Why Precise Leak Location Matters

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.

Detection and Repair Under One Company

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.
