Why slab leaks are common in the Valley
Most Phoenix-area homes are built on concrete slabs with copper or PEX lines running beneath them. Shifting expansive soils, hard-water corrosion and pipe abrasion against concrete can open pinhole leaks you can't see.
Warning signs
An unexplained jump in your water bill, the sound of running water when everything is off, warm spots on tile floors, cracked flooring, or a water meter that keeps spinning with all fixtures off all point to a hidden leak.
Repair options
Once a leak is pinpointed with acoustic and thermal equipment, options include a spot repair through the slab, rerouting the line through walls or attic, or a full repipe for homes with repeated leaks. A good plumber explains the pros and cons of each.

Leak & Slab Leak Detection FAQs
How do I check for a leak myself?
Turn off every fixture and watch your water meter's leak indicator. If it moves, water is going somewhere.
Does homeowners insurance cover slab leaks?
Policies differ. Many cover resulting water damage but not the pipe repair itself — check with your insurer.
Is rerouting better than breaking the slab?
Often, because it avoids jackhammering floors, but it depends on the home's layout. Ask for both quotes.
