Slab Leak Detection
A leak in the pipes under your slab can hide for months. We find it without tearing up your whole floor, then fix or reroute the line so it stays dry.
Most Phoenix homes sit on a concrete slab, with water lines running underneath. When one of those pipes leaks, the water has nowhere to go, so it hides. The clues are a hot spot on the floor, the sound of running water when everything is off, a spike in the water bill, or a crack that keeps growing. Left alone, a slab leak can undermine the foundation.
How We Find a Slab Leak
We do not start by breaking concrete. We use listening gear and pressure tests to pinpoint where the leak is first. Once we know the exact spot, we open only what we must. Depending on the line, we repair that section or reroute the pipe so it no longer runs under the slab, which is often the smarter long-term fix.

FAQ
Slab Leak Detection, common questions
Where can I find slab leak detection near me in Phoenix?
Rapid Rooter Plumbing traces and repairs slab leaks across Phoenix and the Valley. We pinpoint the leak first, keep the concrete work small, and fix it for good. Call (602) 555-0119 for an upfront flat-rate quote on detection and any repair.
Is it better to repair a slab leak or reroute the pipe?
A single leak in otherwise good pipe can be spot-repaired. But if the line is old or has leaked before, rerouting it above the slab costs more now and saves you from breaking concrete again later. We find the leak first, then tell you honestly which fix makes sense for your home and your budget.
How do you find a slab leak without tearing up my floor?
We use electronic listening tools and pressure tests to pinpoint the leak before we open anything. That tells us the exact spot under the slab, so we cut only where we must instead of guessing across the whole floor. Finding it first is what keeps the mess, and the cost, small.
What are the signs of a slab leak?
Watch for a warm spot on the floor, the sound of running water when every tap is off, a water bill that jumped for no reason, cracks in the floor or walls, or a musty smell. Any one of these is worth a look. Catching a slab leak early is far cheaper than fixing foundation damage later.
Are your slab leak repairs guaranteed?
Yes. We are licensed in Arizona as ROC 339021 and insured, and we stand behind the work. Because we pinpoint the leak before we dig and fix the real cause, the repair holds. If something we did fails, we come back and make it right. You get the flat price and the plan before any concrete is touched.
