On any water heater, the shut off is on the incoming cold pipe.
Not plugged in? Gas valve shut? Oil ran out? Thermostat /aquastat not calling for heat?
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 heats up the thermo couple which opens up the gas control valve allowing gas to flow to the main burner. if the pilot goes out the thrmo couple will cool and shut the gas valve so gas does not come out
A thermocouple on a gas heater operates by generating a small voltage when heated by the pilot flame. This voltage signals the gas valve to stay open, allowing gas to flow to the burner. If the pilot flame is extinguished, the lack of voltage from the thermocouple will cause the gas valve to shut off, preventing a gas leak.
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.
Shut off the gas valve feeding the heater until a qualfied service person diagnoses and repairs the problem. The valve should be just outside the heater, turn the handle 90 degrees until it is perpendicular to the pipe.
You clean bricks in a gas wall heater by turning the gas off and scrubbing them with a non flammable cleaner.
Yes you need to shut off the Main water valve. Usually found in the basement or outside the house near the meter. Also you need to shut off the Gas valve located at the water heater, or the Breaker located in the breaker box/ fuse panel. Sometimes the water heater will have its own Switch box, located on the power wire
No because water heaters have a safety valves and when the pilot light goes out the safety valve shuts off the gas
YES and No Yes if you are going to be working on the gas water heater and No if you are working on a cold water line and if you are working on a hot water line you can shut off the gas or electric to the water heater so in case your water heater drains but what I usually do is just turn the water heater's water supply valve off.
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.
