Three signs of a slab leak in a Central Texas home

A warm patch on a tile floor, a water bill that jumped without a change in habits, and the sound of running water with every tap off. Any one of them is worth a pressure test. All three together is a slab leak until proven otherwise.

Clay soil around Austin moves with the seasons, which is why copper lines under slabs fail here more than in most of the country. A reroute through the attic is often cheaper than opening the floor and avoids the next failure on the same line.
