Find the hidden leak — without tearing up your home.

A slab leak is a leak in a water-supply pipe beneath a concrete foundation. Signs can include an unexplained water-bill increase, a moving meter with fixtures off, damp flooring, warm spots or the sound of running water. Those symptoms can have other causes, so detection comes before opening the floor. Once the leak is located, repair options depend on pipe condition and access and may include a targeted repair or rerouting. For active flooding, safely shut off the water if possible and keep clear of wet electrical equipment.

A smart shutoff is installed on the main water line and monitors water use for patterns that may indicate a leak. Depending on the model, it can close the valve automatically and send phone alerts; some systems also work with separate moisture sensors. Detection settings, connectivity and power requirements vary, so no device guarantees it will catch every leak. Installation includes reviewing normal household use and accessible shutoff operation. We help you choose a system that fits your plumbing and explain its alerts, limitations and manual controls.
