Earthquake Gas Shut-Off Valve Installation

An earthquake valve closes the gas line automatically when the ground shakes hard enough, so a broken line does not turn a quake into a fire. We install and test them.

Why Bay Area homeowners install one

Gas keeps flowing after a quake unless someone shuts it off by hand
Required by some cities at sale or on permitted work, and by some insurers
Installs on the house side of the meter, usually in under a day
No power or batteries needed; the valve is purely mechanical

How we handle it

Check your meter and line

We look at the meter setup, the pipe size and where the valve will sit.

Install the valve

A certified seismic valve sized for your line, installed to code and permitted where required.

Test and show you the reset

We test the installation and walk you through how to reset the valve after it trips.

Questions we hear

Is an earthquake shut-off valve required?

It depends on the city. Some East Bay cities require one when a home is sold or when gas work is permitted. We will tell you what applies to your address.

What happens after the valve trips?

Gas stays off until the valve is reset by hand. Once you have checked for leaks, or had us check, the reset takes a minute.

Can I install it myself?

Gas work should be done by a plumber, and most cities require a permit and inspection. We handle both.
