Earthquake Valves

About Natural Gas Earthquake Shut-off Valves

A natural gas earthquake shut-off valve automatically shuts off your gas service when an earthquake of a sufficient magnitude occurs at your home's location. After the quake has stopped and you have determined that it is safe to do so, follow the manufacturer's instructions for restoring your gas service. You will need to make sure no gas leaks exist and re-light your pilot lights. You must ensure that your appliances are safe before operating them. The Gas Company or a service agency can restore your gas service, but remember that it may take many days or even weeks before someone can come to your location in a major emergency. (The Gas Company charges a fee to reset valves and re-light pilot lights.)

Earthquake Valve Installation Requirements

If you choose to have an earthquake gas shut-off valve installed, or are mandated to have one by your insurance company or the local building code, the valve must be installed on the downstream side of the meter. The downstream side is the customer side of the meter. See picture:

NOTE: When you hire a licensed contractor to install your valve, it is important that you ensure that the valve is installed on the downstream side (that is, the customer side of the meter), not on The Gas Company's property. Earthquake valves are not permitted in utility curb meter vaults.
