How to Reset Your Seismic Shutoff Valve

How to Reset Your Seismic Shutoff Valve

The seismic valve might be one of the most important pieces in a home. The “in case of emergency” switch is one that many homeowners are not aware of – but they definitely should be. The valve is also known as the “earthquake valve,” for reasons you’ll see below.

What Is the Seismic Valve?

This valve is used to shut off gas whenever there is a break in a pipe. You may also use the shutoff when there are severe natural disasters, such as earthquakes. What makes this so valuable is that it is designed to automatically shut off whenever an earthquake occurs.

The valve is most common in states like California that have a higher risk of earthquakes. In these areas, the “earthquake valve” is placed on the outside of the home. The seismic valve attaches to the gas meter on the outside of the home and looks like an extension of that. In California, it’s a law that every home has working equipment in case of emergency.

How Do You Reset the Seismic Valve?

The gas shut off valve has colors indicating whether gas is still flowing or not. The red color on the valve indicates that the gas has been shut off. To double-check this, look at the tube to ensure that no gas is moving through. The green color represents a reset. To reset you would close the wrench-operated inlet valve. After waiting a couple of minutes, you turn the green knob to reset the gas line.

Seismic valves are a vital resource in states prone to earthquakes, like here in California. Our trained technicians can help with seismic valve installation and resetting your shutoff valve whenever a pipe breaks, an earthquake hits, or another natural disaster occurs.

Quick Response Time

The response from Gotelli Plumbing was excellent. The next time Tom arrived right on time and the quality of his work was outstanding. When he finished he walked me through everything he had done and I could not have been more pleased with the results. I’m so thankful to have such professionals available when need and on such short notice.

Excellent Service

Tom provided excellent service. He is obviously experienced- and quickly solved the problem. Our gas had to be shut off, so we were without our stove to cook, furnace to heat and hot water. Our home is happy again!
