My sister's building (she lives with her fiance whos father owns the 6 family building) has been plumbed properly but the connection is wrong in the boiler room. I haven't been there to see but every apartment in her building is reverse hot water and cold water. The connections are 'right' at every fixture including the shower but hot comes when you turn the cold water handle and vice versa. If it was only the sinks I'd say just switch the speedy connections but it's also the showers and she wants it fixed.
My question is, if it is indeed only connected incorrectly in the boiler room and an easy fix, is it advisable to reconnect, putting cold water into the copper pipes that previously held hot water? if so, how long should I wait until running water through the line? I don't want to damage the pipes and leave them with an even bigger project. It's a fairly old building but it may have been replumbed somewhat recently
To answer any obvious questions, No I would not do anything without a permit and licensed plumber stamp, and I would never do anything unless I was 2000% sure I knew exactly what I was doing which is why I'm asking here.
Am I correct in assuming I would just have to wait the usual time you would after installing new copper?
I don't even use a wet rag when cleaning my joints because I'm paranoid about stressing the joints too soon and really you don't need a wet rag. A dry one works fine.
Thank you
