Trying to switch off the hot water so I can change the Bathroom taps. Never 100% sure of what we actually have but its a cold water tank in the loft, feeding a cold water tank in an airing cupboard. Theres three Red Valves in the airing cupboard, I've tried each one in turn to close it off, then gave the hot water tap a quick run, each time the hot water flows freely and shows no sign of stopping, although it was only 20 seconds or so that i ran it for.
Am i missing something obvious that i should/could be doing?
