How to drain hot water

[domiles1]

I need to replace a hot tap in my bathroom so need to stop the flow of water. I have a fairly old hot water system - a tank in a cupboard upstairs, heated by a boiler downstairs. Do I need to just turn off the mains water and drain all the hot from the tank or is there likely to be a valve or tap on the outlet of the hot water tank?

Thanks

Buy a pipe freezing kit, ensure your hot supply pipes are cold, follow the instructions with the kit and freeze the pipe. No draining down, no fluffing around with leaky stuck valves. Job done.

What do you prefer to use instead, Jase158?

yep lever valves.

much better but still not fool proof
