Seismic Gas Shut-Off Valves: What They Do

A seismic gas shut-off valve, also called an earthquake valve, closes off the gas supply to your home on its own when it senses strong ground motion. The idea is simple: if shaking damages a gas line, the gas stops flowing instead of building up.

Why think about one here?

We constantly get tremors and earthquakes in this part of Southern California. Shaking can damage gas lines, and a leaking gas line is a fire risk. If you think you already have a leak, start with our gas leak detection page.
