Gas Shut Off Devices

Automatic gas shut off valves are designed for earthquakes, accidents and any event of impact. We have installed hundreds of automatic gas shut off valves to the manufacture’s specification. Non-emergency shut offs will occur if the automatic gas shut off is not installed according to manufacturer’s specifications. For example, the impact of heavy vehicles can trigger a non-emergency shut off.

Some cities and counties have regulations that require the installation of automatic gas shutoff devices, which may include excess flow gas shutoff valves and/or earthquake actuated gas shutoff valves. Regulations vary, but generally apply to new building construction, or significant alterations or additions to existing buildings. Check with your local city or county agency to see if regulations apply in your area.

If a customer installs an excess flow gas shutoff valve or earthquake actuated gas shutoff valve, it should be one that is certified by the State of California and it should be installed by a licensed plumbing contractor in accordance to the manufacturers instructions. PG&E does not install or service seismic actuated or excess flow gas shutoff valves, or recommend specific contractors for customer applications.

The State of California is required to approve all excess flow gas shutoff valves and earthquake actuated gas shutoff valves used in the State of California. The State of California is required to approve all excess flow gas shutoff valves and earthquake actuated gas shutoff valves used in the State of California. A list of approved valves is available on the DSA Gas Shut-off Valves Certification Program webpage.

Gas Service Shutoff Valves

Manually turning off the gas service shutoff valve is the most common method to stop the flow of gas serving a building, or part of a building, in case of an emergency. Gas service shutoff valves are installed by PG&E at all gas meter locations or outside locations if the meter is not accessible from the outside.

Excess flow gas shutoff valves and earthquake actuated gas shutoff valves must be installed on the buildings gas houseline piping (the gas pipe connecting your appliances to the gas meter) downstream of the utility point of delivery; i.e. after the PG&E gas shutoff valve, pressure regulator (if installed), meter(s), and the service tee. No attachments or connections of any kind are allowed on utility facilities prior to the point where the service tee connects to the gas houseline piping. Once installed, the valve must not obstruct the operation or serviceability of PG&E’s piping, gas service shutoff valve, gas meter or gas pressure regulating equipment.

In the event that a gas service shutoff valve or an automatic gas shutoff device is closed, there may be a considerable delay before PG&E can turn your service on, but do not turn it on yourself. PG&E or another qualified professional should perform a safety check, restore gas service, and relight any appliance pilots, even if the closure was not caused by an earthquake.
