I need to fit a replacement electric shower but im having a few issues isolating the water supply to the shower unit so im here for some advice.
The shower was here when i moved in and looks like it was an addition to the original plumbing work. Unfortunately there is no isolation valve on the pipe work that goes to the shower.
No problem as i thought i could turn off the mains water instead. In order to remove the old shower unit
upon turning off the mains cold water, the taps down stairs in the kitchen etc all have no water supply as you'd expect.
Upstairs however, the cold taps in the bathroom continue to flow hence im a bit reluctant to disconnect the shower inlet yet...
Up in the loft ive got three large tanks all connected up to each other as highlighted by the green lines
Tank A has the mains cold feed and a pipe has been tee'd off the cold feed directly to the shower unit using speed fit connections. No where along this "new" pipe to the shower unit can i find an isolation valve
I think that turning off the mains should safely cut off the supply to the shower since it comes off the mains feed into but id like to be a bit more sure of that before i go ahead and do it...any one able to provide a bit more knowledge on this?
On a less important note but something ill might need to know for the future is can anyone explain where the upstairs taps might being fed from? I guess it will be tanks b or c
The upstairs taps all have isolation valves near the taps which is good but if i want to change any pipe work in future it would be good to understand where they are being fed from and if i might need to completely drain those tanks in order to make any changes
(p.s I believe the system ive got is on open vented CH gravity fed domestic water.)
Thanks
