Is it a slab leak?

A meter that moves with every fixture off, a rising bill or warm spots on the floor are common signs of a slab leak. Detection pinpoints the spot so less floor is opened. When a home has had several slab leaks, repiping is often discussed; our guides to slab leak repair cost and whole house repiping cost compare the options.

Common questions

How do I test for a hidden leak?

Turn off all water use and watch the meter for 15 minutes. If it moves, water is escaping somewhere.
