Hi, I have used is website many times before and it has got me out of stuck a few times, this time I am positing with the hope of a little help!
I am fitting a replacement shower at my parents,
The hot water system is an indirect system, there are 2 header tanks in the loft and these are vented.
I need to knock off the hot water before disconnecting the shower.
My understanding was that if I knock off the cold water feed to the copper cylinder and drain the hot water at a tap downstairs (shower is upstairs by the way) this would empty the system to a point where I can work on the shower.
The hot water seems to run out downstairs at a considerable rate still after even 10 minutes, am I missing something? need I isolate other parts of the system?
I have done work on my own hot water system, this is a basic system with no boiler involved though.
I know I am capable of the physical changing over of the shower unit if only I could isolate the hot water!
Any help is appreciated!
