Had a new plumber join the firm and he had to tee in to a 1.5" galv hot supply, for a new cleaner sink. School wanted freeze as old system runs like orange soup for days after refilling once drained. Froze pipe with 2 freeze machines, cut pipe and he went and sat in van and had lunch.. Wtf! Obviously lost the ice plugand came back to one all mighty leak (cold tanks on roof of 5 storey block) had to drain down, there's your soup. Flooded various classrooms, new carpets text books etc nightmare
Think he learned a lesson that day never cut a frozen pipe and leave unattended. Valve off or get the job done

😀 did he turn the secondary pumps off as seen that before (domestic plumber) went to a call out in a school he had to t into the line was inch so turned all the Andrews off and put freeze cans on and started to freeze 5 mins later it was frozen opened tap further down the line to confirm,

All good there so he starts cutting his piece out first cut ok second cut ok, poped the piece out and then heard a grumble, thinks nothing of it 30 seconds later the ice plug comes shooting out the cut end of the pipe and landed on a Window and cracked it, and hot water starts coming out like a fountain 😀 so what does he do crushes the end of the pipe and legs it,

To be never heard of again

So moral of the story domestic plumbers, don't try and do commercial plumbing unattended 😉

Personally i woundt have bothered to crush the pipe. But I would have been found easily enough by the trail of crap pouring out my R'send

All was isolated by the other plumbers changing all the iron trvs on the cast rads all over school. I was an apprentice then and working on trv's. Remember coming down the hall to see a waterfall. When the pipes cut open ambient tempreature comes in to play (summer holidays). I don't like freezing. Had a firm come in to do a liquid nitrogen freeze at a job once. Welder missed a big gap round the back of a 5" flange and 'pee'd' out. Nitrogen still froze it again under flow really impressive
