I have been attempting to install a hot and cold feed pipe extentions at a care home where I work. I located 2 x 22mm pipes in the false roof, each marked with red and blue tape to identify. The cold (blue) pipe has a normal stop cock and the hot pipe has a gate valve.
I turned off the cold water stop tap, which in turn stopped both hot and cold water outlets at the existing taps. I then 'tee'd into the pipe and fitted the required extension. So now I have the cold supply.
My problem is that it would appear the other pipe marked with red tape and constantly hot on both sides (even when I turn off the gate valve) disallows my being able to attach a tee piece and as such, I have no idea how to connect to a hot water supply.
There is no mass pipework in the roof area - only the two as described.
The current systems in use are a mixture of three different boilers and hot water water storage tanks - all added to over the years as the home has been altered, extended etc.
Any ideas ?
