A natural gas seismic shut-off valve automatically shuts off your gas service when an earthquake of a sufficient magnitude occurs at your home's location. An excess flow valve automatically shuts off your gas service when a significant gas leak or overpressure surge occurs at a pipe or appliance located beyond the point where the valve is installed.
If an earthquake or other significant event causes your seismic shut-off or excess flow valve to close, you may follow the manufacturer's instructions for resetting the valve so that gas flows again. However, The Gas Company recommends that you contact a licensed, qualified professional or The Gas Company to reset the valve, and to verify that no gas leaks exist, to ensure that all of your gas appliances are safe before being placed back in operation and to re-light your pilot lights. Remember that following a major emergency it may take many days or even weeks before someone can come to your location. (The Gas Company charges a fee to reset valves and re-light pilot lights.)

Seismic and Excess Flow Valve Installation Requirements
If you choose to have a seismic gas shut-off or excess flow valve installed, or are mandated to have one by your insurance company or the local Department of Building and Safety, the valve must be installed on the customer’s houseline. If installation requires gas service closure, you must contact The Gas Company to shut-off the service and restore service when installation is completed.
Under the regulations of the California Public Utilities Commission (CPUC), General Order 112-E, only The Gas Company or its certified contractors are authorized to operate the gas service shut-off valve.
Gas service shut-off and restoration of service orders can be scheduled by contacting the gas company at 1-800- 427-2200.
NOTE: When you hire a licensed, qualified professional to install your seismic or excess flow valve, you must ensure that the valve is installed on your houseline, not on The Gas Company’s facilities. The Gas Company’s facilities include all of the pipe fittings installed and maintained by The Gas Company, up to and including the last elbow or tee connecting to your houseline. All unauthorized valve installations found on The Gas Company’s facilities will be removed. In addition, Seismic or excess flow valves are not permitted in utility curb meter vaults.
