What is seismic shut off valve?
Earthquake natural gas shut-off valve (also known as a seismic natural gas shut-off valve) automatically shuts off your natural gas service when an earthquake of a sufficient magnitude occurs at your home.
What does an earthquake valve do?
Earthquake valves, or seismic shut-off valves, are used as a safety device to shut off natural gas lines in the event of an earthquake. They generally are installed on the exterior of a residence or business in order to stop gas flow when an earthquake of significant magnitude transpires.
Do I need an earthquake shut off valve?
Every building that’s connected to gas in California should have an earthquake shut-off valve. That means every Californian should understand how an earthquake gas shut off valve works. Here are the important things to know, including how to update your home and be prepared if an earthquake does rattle your gas line.
Who can install a seismic shut off valve?
licensed plumbing contractor
If a customer installs an excess flow gas shut-off valve or earthquake-actuated gas shut-off valve, the valve must be certified by the State of California. A licensed plumbing contractor must install it according to the manufacturer’s instructions.
How do you reset a earthquake gas shut off valve?
To reset, all you need is a screwdriver. Insert the screwdriver into the reset slot and rotate clockwise. You should be able to see the color switch from red to green to indicate that the valve is now open.
How do you reset a little firefighter earthquake valve?
To reset valve: Close wrench-operated meter inlet valve. After waiting five minutes, reset the valve by turning the “reset” shaft with a screwdriver 1/8 turn (45°) in the direction indicated. The slot on the reset shaft should spring back to its original, vertical, position when the screwdriver is removed.
How much is an earthquake valve?
Prices generally range between $250 and $750, including parts and labor. If you’re in an earthquake-prone area, a seismic shut-off valve is an important safety measure to prevent fires and explosions from your gas line during a seismic event.
Are earthquake valves required in California?
About one in four fires after an earthquake is related to natural gas leaks. The California State Architect is required to approve automatic gas shutoff valves to be installed in the State of California, pursuant to Section 19202 of the State of California Health and Safety Code.
How do you turn off the gas during an earthquake?
Turn off the gas service shutoff valve typically located near the gas meter, if it’s safe to do so. Evacuate the building if leaking gas starts to burn. Do not try to put the flame out. Call 9-1-1 immediately and then call PG&E at 1-800-743-5000.
How much does it cost to have a gas shut off valve installed?
between $300 and $500
Installation of a gas shut-off valve costs between $300 and $500. Depending on the pipe size, the valves cost between $100 and $300. You’ll pay an additional $150 to $200 for labor and other supplies.
Should you turn off your gas after an earthquake?
Turn off the gas service shutoff valve typically located near the gas meter, if it’s safe to do so. Avoid turning off your home’s gas without a clear sign that it is leaking. It may take a long time for PG&E to turn your gas services back on. Check for downed or damaged electric utility lines.
What is the difference between an earthquake valve and seismic valve?
Unsourced material may be challenged and removed. An earthquake valve (or seismic valve) is an automatic method to shut off the low pressure regulated gas supply to a structure during a major earthquake and/or if a pipe is broken. These are applicable both to utility-supplied natural gas and to gas from liquefied petroleum gas (LPG).
What is an earthquake natural gas shut-off valve?
Earthquake natural gas shut-off valve (also known as a seismic natural gas shut-off valve) automatically shuts off your natural gas service when an earthquake of a sufficient magnitude occurs at your home.
Where can I find additional information about earthquake valves?
Additional information regarding earthquake valves and natural gas service restoration after a valve activates can be found in Tariff Book, Rule 10, Section G, “Earthquake Valve Service.” If you have questions about earthquake and excess-flow valve installation requirements, contact your local Building and Safety Department.
What is the maximum pressure for a seismic valve?
Seismic valves are available with pressure classes (7 psig and 60 psig max). An upstream pressure regulator can reduce the gas pressure below 60 psig before the seismic shut-off valves. A valve is closed when the flow exceeds a certain limit that is appropriate to the application.
