What Gas Shut-Off Valves Do. The basic purpose of a gas shut off valve is to cut the flow of gas to your house in the event of an earthquake (or, depending on the type of valve, a potentially dangerous leak due to other causes.) Each device has a simple mechanism inside which activates and blocks the flow of gas.
.
Simply so, where is the main shut off valve for gas?
Houses with natural gas have a main shutoff valve (Fig. A) located just before the gas meter. This valve, often called the street-side valve, is normally a rectangular nub (Photo 1). When the long side of the nub or handle is parallel to the incoming gas line, it's open and the gas is flowing.
Also Know, can I turn my gas back on myself? Once the valve is turned off, do not turn it back on by yourself. It must be turned on by a gas company technician. The gas company will likely perform a pressure test on the system and relight all pilot lights in the house as part of turning the gas back on.
Similarly, you may ask, how do I find my gas shut off valve?
The gas meter and gas service shutoff valve is usually located on the side or in front of the building. If the building has a breezeway, it could be located there.
Is it safe to disconnect a gas stove?
The safe way is to first turn off the gas. This can be easily done with the gas meter or the shut-off isolation valve. If there is no other shutoff valve found on the supply line close to the appliance, you will need to turn off the gas supply to the entire house.

When gas lines are repaired and service is restored, the valve automatically resets itself.What is an excess flow valve?
Excess Flow valves are in-line valves through which pressurized gas or liquid flows in either direction. These are spring-loaded flow shut-off valves, which will only close when the flow through the valve exceeds a predetermined closing flow rate in the direction marked on the valve.Where is the hot water shut off valve?
