Seismic Gas Shut-Off Valve Cerritos CA

Cerritos sits in a region where strong earthquakes are a fact of life. After a major quake, broken gas lines and loose appliance connections can release gas into a house, and fires that follow earthquakes are a serious risk. A seismic gas shut-off valve closes automatically when it senses strong shaking, cutting off gas at the meter before it reaches damaged piping.

Some Southern California cities require a seismic valve when a home is sold, remodeled or has new gas work. Even where it is not required, many homeowners choose one because it works when nobody is home to turn off the gas by hand.

Questions

Earthquake Gas Shut-Off Valves FAQs

What does a seismic gas shut-off valve do?

It closes automatically during strong shaking, stopping gas from flowing past the meter into the house. This reduces the chance of gas feeding a fire if lines are damaged.

Is a seismic shut-off valve required in Cerritos?

Requirements vary by city and by the type of work being done. We check what applies to your address and project when you call.

Will the valve close if a truck drives by?

Certified valves are designed to ignore everyday vibration and close only with strong ground motion. A hard bump to the valve itself can trip it, which is why it is mounted securely.

How do I reset the valve after it closes?

Before any reset, the house must be checked for leaks, because the valve closed for a reason. After that, the valve is reset and every pilot light has to be relit. We can do both for you.

What is the difference between a seismic valve and an excess flow valve?

A seismic valve reacts to shaking. An excess flow valve reacts to a sudden jump in gas flow, such as a broken line. Both stop gas, but they respond to different events.
