Hi, I want to replace the tap in my bathroom sink and fit a isolating valves at the same time. How do I drain the hot water supply? I have a combi boiler. Do I just turn off the boiler, turn off the mains cold supply then turn on all the taps in the flat?
To refil, turn on mains cold water valve, refill boiler up to pressure with filling loop, then turn on boiler?
Anything else I have forgotton?
Thanks David.
