Why You Should Have an Earthquake Valve on Your Gas Meter

An earthquake valve is a device that automatically shuts off the flow of gas to your home in the event of an earthquake. This is a crucial safety measure, as gas leaks are one of the leading causes of fires following an earthquake. In addition, having an earthquake valve can give you peace of mind, knowing that your home and family are protected in the event of a natural disaster.

What is a Gas Meter

Gas meters are devices that measure the volume of gas that is supplied to a particular property. They usually consist of a dial and a pointer that rotates as gas flows through the meter. The position of the pointer indicates the amount of gas that has been used. 

Meters are typically located in a box outside the property, often on the pavement or near the boundary. The box is usually marked with a warning sign telling you not to touch it as it contains high-voltage electrical equipment. 

Gas meters are read periodically by your gas supplier so that they can send you a bill. Most meters these days are what’s known as “smart meters.” This means they can automatically send readings to your supplier, so you don’t have to worry about manually taking them yourself. 


Types of Gas Meters 

There are two main types of gas meters: positive displacement and rotary. Positive displacement meters measure the volume of gas passing through them by trapping a fixed volume of gas in a chamber and then releasing it as more gas flows in. Rotary meters measure the volume of gas passing through them by means of two or more rotating gears that turn in proportion to the flow of gas. The most common type of rotary meter is the spiral-type meter.

How Earthquake Valves Work

An earthquake valve is a device that automatically shuts off the flow of gas to your home in the event of an earthquake. They are usually installed near the meter where the main gas line comes into your house. There are two types of earthquake valves: mechanical and electromagnetic. Mechanical earthquake valves use a weight or spring inside the device to detect when an earthquake has occurred. Electromagnetic earthquake valves use sensors to detect seismic activity. Most earthquake valves are triggered by a sensor that detects seismic activity; when the sensor goes off, it signals the valve to close. Some valves can also be manually turned off in case you need to shut off the gas for any reason other than an earthquake. 

Earthquake valves are not required by law, but many local building codes recommend or require them in new construction. They typically cost between $500 and $2000, depending on the size and type of valve. So, are they worth the investment? That depends on a lot of factors, including how likely it is that your home will be damaged by an earthquake and whether or not your insurance company offers a discount for having one installed. 


Where is the Earthquake Valve Located? 

The earthquake valve is typically located near where the natural gas line enters your home, often near the water heater or furnace. In some cases, the valve may be located outside near the gas meter. If you’re unsure of the location of your home’s earthquake valve, contact your local utility company for assistance. They will be able to send someone out to help locate the valve and show you how to reset it after an earthquake. 


Why Are Earthquake Values Important? 

If you live in an area that’s prone to earthquakes, then having an earthquake valve installed on your gas line is a wise investment. Gas lines are often damaged during earthquakes, which can lead to dangerous leaks. In fact, one of the most devastating fires following the 1989 Loma Prieta earthquake was caused by a broken gas line. By having an earthquake valve installed, you can rest assured, knowing that your home and family will be protected in the event of an earthquake. 

Where Are Earthquake Valves Placed? 

  • On the Main Gas Line: If you have a natural gas service line running to your home, there will likely be an earthquake valve installed on this line. The valve is usually located where the gas line enters the house. In many cases, it will be located near the meter. In other cases, it may be installed on an outdoor faucet or in the basement near the main shut-off valve for your home’s gas supply.


  • On Individual Appliances: Some homes have individual appliances that are supplied by their own dedicated gas lines. These appliances might include a stove, dryer, or water heater. If your home has any appliance that uses natural gas, there should be an earthquake valve installed on the line supplying gas to that appliance. These valves are usually located near the base of the appliance.


Installing an Earthquake Valve

Installing an earthquake valve is typically a job for a professional plumber or gas fitter. The installation process itself is not very complicated, but it is important to make sure that it is done correctly in order to ensure its proper function. Once installed, earthquake valves require very little maintenance; they should be inspected annually to ensure that they are in good working condition.

Protect your Home Today!

Earthquakes are a part of life in California, so it’s important to be prepared. Part of being prepared is having the proper supplies and equipment in your home, like earthquake valves. Earthquake valves are installed on your gas meter and automatically shut off the flow of gas if there is an earthquake. They should be placed as close to the ground as possible so that they can easily shut off the flow of gas if there is an earthquake. If you don’t have earthquake valves in your home, make sure to get them installed by a qualified contractor as soon as possible.
