Earthquake Shut-Off Valve for Gas Installation in Los Angeles
Protect your home and family with expert installation from Over Under Plumbing.
Why Earthquake Shut Off Valves Matter in Los Angeles
Los Angeles is no stranger to earthquakes, and even moderate shaking can damage gas lines. When pipes break or fittings loosen, gas leaks can spark fires or explosions. An earthquake shut off valve for gas—also called a seismic gas shut off valve—is designed to prevent that danger by automatically cutting off gas flow at the gas meter during strong seismic activity.
This simple device has saved countless properties from disaster. In fact, many Los Angeles municipalities and insurance companies now require or recommend a gas earthquake valve for safety compliance. Whether you own a single-family home, rental unit, or commercial building, installing a seismic shut off gas valve is one of the smartest investments you can make for your property.
Benefits of Installing a Seismic Shut Off Gas Valve
Adding a gas meter earthquake valve isn’t just about checking a box on city code. It delivers lasting protection for you, your family, and your property.
Automatic Protection: Valve shuts off gas instantly during strong quakes.
Reduces Fire Risk: Stops gas leaks that could ignite after pipe damage.
Insurance Benefits: Many carriers require or discount homes with valves.
24/7 Safety: Works even if you’re away from home.
Peace of Mind: Know your family and property are safer every day.
Easy Manual Use: You can shut the valve off yourself if you ever smell gas.
How Earthquake Shut-Off Valves for Gas Work
An earthquake shut-off valve for gas is a small device installed on your gas meter that provides automatic protection when danger strikes. It’s designed to sense conditions that could indicate a leak or rupture and shut off gas flow instantly to prevent fire or explosion.
There are two main types used in Los Angeles homes and businesses:
- Seismic Gas Valve (SGV): Reacts to strong ground vibrations (around magnitude 5.4 or higher). When shaking is detected, it automatically closes and stops gas flow.
- Excess Flow Valve (EFV): Responds to sudden surges in gas flow—such as when a pipe breaks or fitting disconnects—and immediately shuts off the supply.
Once triggered, the valve stays closed until it is manually reset. After an earthquake or suspected leak, we recommend having a professional plumber inspect your lines before restoring service.
Many property owners choose to install both SGV and EFV for maximum safety. At Over Under Plumbing, we’ll help you decide which option best fits your property, insurance requirements, and local city codes.
