Earthquake Gas Shutoff Valve or Excess-Flow Valve
The basic purpose of a gas shut-off valve is to cut off the gas supply to your house in the event of an earthquake or, depending on the type of valve, a potentially dangerous leak from other causes. Each device has a simple mechanism inside that activates and blocks the flow of gas. Different manufacturers have their own unique methods of restricting gas flow, but they all operate in essentially the same way.
These valves have grown increasingly popular in California homes and businesses to enhance safety during earthquakes. Some municipalities have begun to require the installation of earthquake shut-off valves. Whether you are required by law to install a valve or just want to ensure that your home or business is protected.
Earthquake Gas Shutoff Valve or Excess-Flow Valve
Safety is our priority. If an earthquake occurs and your natural gas pipe is damaged, it may place you and your family in grave danger. Do not risk the potentially deadly hazards posed by leaking gas. Take preventive measures with a shutoff valve to halt the flow of gas when necessary.
When it comes to natural gas, safety is crucial. A properly installed shutoff valve can make all the difference in your well-being and the safety of your property. Our team of licensed plumbers serves residential, commercial, and industrial property owners across Southern California.
Installing an earthquake shut-off valve can provide benefits and protections that include:
- Loss of life in fires or explosions after an earthquake
- Prevent loss of your valuables and sentimental possessions
- Some homeowners’ insurance companies offer a discount when a valve is installed
- Depending on the valve, your gas will be shut off in case they detect a gas leak
- Peace of mind in knowing that your home is protected, even if you are not home
Seismic Valve vs. Excess-Flow Valve
While it’s possible to shut off your natural gas manually, the following specialized valves are available that can automatically shut off your service in case of an emergency:
An 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 sufficient magnitude occurs at your home.
An excess flow valve (EFV) automatically closes and restricts the flow of natural gas in the event an underground pipe is damaged or if there is a significant increase in the flow of natural gas to the meter.
Do I Need An Earthquake Shut-Off Valve?
Earthquake shut-off valves are not universally mandatory across California for all homes, but they are legally required in specific situations, depending on your local city or county.
The rules are as follows:
- Statewide: Since 2000, earthquake shut-off valves have been required for all newly constructed buildings.
- Local Rules: Many cities and counties, such as the City of Los Angeles, have passed local laws that demand a valve before a property is sold, during major remodels, or when gas meters are altered.
- Utility Policies: Utility providers like SoCalGas do not install earthquake shut-off valves and prohibit them on their side of the gas meter. Any valve installed must be on the customer’s side by a licensed plumber
