Do hot water heaters have a shut off valve?
Turning the Water off at the Water Heater A water heater has two shut-off valves. A cold water inlet valve (often identified by a blue handle) feeds cold water from the main supply into the water heater. This is the valve to shut off if you need to repair or replace the water heater.
Will a hot water heater burn up without water?
If water pressure is lost on the cold water side, the tank can siphon down through the cold water inlet till it reaches the bottom of the dip tube. Then since there’s no water in the tank to absorb heat, the dip tube can melt and the tank can be damaged.
Should I turn off my hot water heater if my pipes are frozen?

Should I keep my water heater on all the time?
It’s better to leave the hot water heater on all the time, rather than turning it on and off. Your immersion heater or boiler will heat up hot water which is stored in a tank. As long as the tank has a good insulating jacket, it will keep the water hot all day, without needing to be constantly reheated.
How do I turn the water off to my bathroom upstairs?

How do you drain a hot water tap?
Draining the hot water supply Turn off and/or extinguish your water heater/boiler. In a direct system, simply close the valve to isolate the boiler, then run the hot tap to drain the pipework. In an indirect system, close the valve between the cold water tank and the hot water cylinder, then run the hot taps.
What happens when water tank is empty?
An empty tank will close the downstream pipe, since it cannot drain any more and a full tank will close the upstream pipe, since it can’t fill any more. Once the opposite conditions occur in the system, the pipe(s) will automatically open back up.
What happens if I turn off the water to my house?

What do you do if your hot water heater pipes freeze?
Wrap your external pipes with heat tape, fiberglass, or polyethylene wrap for the best protection. In case your pipes do end up freezing over, try thawing out the pipes by turning up the heat. If you have metal pipes, call a plumber who has an electric pipe-thawing machine.
