I was shocked to find in the basement of my 1950s home (last rennovated in 1991) that large sections of copper plumbing had not been supported with pipe hangers. Sections of up to 12 feet have been left without support.
I am now in the process of installing pipe hangers at intervals of no more than 6 feet. I have two questions.
First, will this make any difference? I assume this plumbing has been there since 1991 and if the joints were to break, then surely they would have done so by now.
Secondly, I am using copper pipe hangers for copper pipe. Is this correct or are plastic better (in terms of being semi-flexible and not damaging the pipe)?
