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.
If you have any questions about your insurance company requirements, contact your insurance company or agent.
