Earthquake Gas Valve

Installs an automatic gas shutoff valve designed for seismic activity, matched to licensed local plumbers experienced with seismic safety devices.

How an Earthquake Gas Valve Protects Your Home

An earthquake, or seismic, gas shutoff valve automatically closes your home’s gas supply when it detects the kind of ground movement associated with a significant earthquake, helping prevent gas-fed fires in the aftermath. In many seismically active areas, it’s a straightforward, one-time installation that provides ongoing protection without any homeowner action required.

An earthquake shutoff valve does its job automatically, exactly when you’d have the least ability to do it yourself.

When to Consider an Earthquake Gas Valve

These situations are common reasons homeowners request installation.

  • You live in a seismically active area and don’t currently have one installed
  • You’re selling a home in a region where buyers commonly ask about this feature
  • Your homeowners insurance offers a discount for having one installed
  • You’re doing other gas line work and want to add this protection at the same time
  • A previous valve has triggered and needs to be reset or reviewed

What to Know Before Requesting Installation

This is licensed-only gas work, but understanding the basics helps.

  • Ask whether the valve is a mechanical type (no power needed) or requires electricity
  • Confirm the sensitivity threshold matches recommended seismic standards for your area
  • Ask what’s involved in resetting the valve if it’s ever triggered
  • Check with your insurer about any discount for having one installed
