I need to change the stopcock on my workshop - it seems to have fallen apart inside but because it’s boxed in, it’ll be a major job to replace the whole thing. I can get to the main part of it though - see pictures. Could I just change the centre part over from the new stopcock? I need to either freeze the pipe somehow or do it live. There is another tap on the system on the way to the workshop stopcock and I’ve carried out a simple test. With just a workshop tap running it takes 13 seconds to fill a 2 litre jug. With the other outside tap running, it takes 28 seconds so considerably lower. Do you think it would be possible for me to change the centre bit over working live? If I did, would it be best to do it with all upstream taps open and the main stopcock on so that there's not too much pressure when I'm trying to screw the innards in, once the guts are changed over, then turn the stopcock off?
