Following on from my "shower too powerful" question, and thanks for your help with that one, I'm on to the next one. Buddy needs to install a stop cock in a 22 mm mains pressure pipe near one of the apartments so they can isolate that room since it's rarely used.
But they can't turn off the water supply to the whole building and "someone" told him, "all he needs to do is freeze the pipe so there's no water flow, cut it and fit the new stopcock and then let it thaw out". Is that so? And is this something we really can reliably do easily from some kit we can hire or what?
TIA
