Hi everyone, I've bought a shower mixer tap and would like to install it but I'm not quite sure how I can turn off my hot water supply. I have shut off the main water supply valve which stops water going to the cold tap but hot water still flows from the hot water tap. I don't have a combi boiler, I have a conventional boiler where you have to heat up the water with gas. Do I just have to run the hot water tap until the tank empties or is there any other steps I should take? I also heard that you can create a vacuum when draining the tank and it could rupture it, is this true? If so how do I prevent it?
Any help would be appreciated as I'm no plumber and I'm not clued up on this sort of thing.
