Your earthquake shut-off valve installation includes a California State Architect-certified valve that meets all ASCE 25-97 and ANSI Z21.70-1981 standards. These aren’t generic products—they’re specifically designed and tested for California’s seismic conditions.The valve activates automatically when it detects earthquake motion of 5.4 magnitude or greater. It doesn’t need electricity, batteries, or any external power source. It’s purely mechanical, which means it works even when the power’s out.In Meyers, where we’re surrounded by fault lines and seismic activity is a constant possibility, having this protection isn’t just smart—it’s essential. The valve protects your entire gas system, including your stove, water heater, furnace, and any other gas appliances. One device protects everything.After installation, you’ll receive documentation for your insurance company and local building department. Many insurers offer discounts for homes with earthquake shut-off valves, so this investment often pays for itself over time.
