Can someone help.
I need to try to change leaking/old bath taps.
The boiler system is conventional - hot water tank and cold tank in the attic.
I understand that I need to turn the cold water tank off using the tap attached to the tank. That sounds quite easy for the cold tap.
There's oddly no isolator tap however between the hot water cylinder and the bath tap. I have never seen this before - there are no isolator taps at all attached to the cylinder. Does this mean then that I have to completely drain the hot water tank first? Sounds like an obvious question but it does seem odd that there would be no way of isolating the tank.
