I've been sent on a job in a United Utilities small pumping station to fit a toilet, sink & water heater.
While I was putting the copper runs in I wanted to change the ISO vavle because it was just coated in paint and I thought that would be alot easier than cleaning it up.
So I followed the pipe back till I got to a stoptap in the main pumping room, and I turned it clockwise, it was that seized up that the handle snapped out before the gate valve closed, then water spewed out from were the handle goes.
I jammed the handle in to stop the water coming out, and tomorrow I plan to replace the stop tap.

The stoptap I want to replace is the one on the cold feed to toilet, taps etc... (the labelled one)
To replace the stoptap I want to turn off the underfloor stoptap, but that is feeding a big gray box in the top corner of the room, and I don't know what will happen if I cut it's water supply off as I don't know what it is.
Can anyone identify it? I was thinking it may be air conditioning but it has big industrial 54mm (I think 54mm) steel pipe coming out of it, so I want to be sure first.
