The shutoff for your house is at the gas meter! The shutoffs otherwise are at each individual fixture. If you shutoff the main and do some work, you will have to purge the air and light every pilot on the individual fixtures as well. Better to get a licenced gas fitter for safety and insurance sakes.
usually outside the building, inside or under the gas meter cabinet.
Install in gas line to shut off gas to building after gas meter, or to isolate an appliance off a gas line.
An Earthquake Shut-Off Valve is a device designed to automatically shut off the flow of natural gas to a building in the event of an earthquake to prevent gas leaks and potential fires.
An air-intake engine shut-off valve regulates air-flow to the motor, and operates as an emergency shut-off valve. There are also shut-off valves on water hoses, so shut-off valves really control the inflow of any liquid or gas.
On any water heater, the shut off is on the incoming cold pipe.
CO, Natural Gas and LPG Detectors are available to configure any desired protection system. Wirless signal from the detectors is sent to a Control Panel and that powers a gas shut off valve.
If electric shut off the current to the elements, if gas shut off the gas valve. Open a hot water faucet to give it air, open the drain valve on the bottom of the heater.
It operates based on seismic activity detection. When an earthquake occurs, the valve senses the vibrations and triggers its mechanism to shut off the gas supply to the building, minimizing the risk of gas-related accidents.
so when the pilot goes out the gas valve is shut off
No, there is no built-in shut off valve, but one could be added to the gas line as an after-market addition.
This depends what shut off valve is in question here. Where the leak is and what type of material is the shut off valve made of.
It shut off water.gas or oil ..... It stop water.oil or gas from coming out of a tank it work just like a water hose
If you want to shut it down completely, turn off the cold water stop going into the hot water tank. If it is an electrical tank shut the breaker off to the HWT. If it is a gas HWT, shut off the gas valve as well.
