Common signs of a slab leak include an unexplained jump in your water bill, warm or wet spots on the floor, the sound of running water when everything is off, low water pressure, and cracks in flooring. If you suspect one, request professional slab leak detection before it worsens.
Slab leaks happen in pipes beneath a home's concrete foundation and are common in Arizona due to soil and hard water.
A quick test: with all water off, check your meter - if it's still moving, you may have a hidden leak.
Detection (acoustic, pressure, or thermal) locates the leak so repair can be targeted.
