Best solution to changing out plumbingI'm most likely to buy a house with a galvanized water system. So I will have to think about replacement for homes in the 70's and 80's. I'm thinking of using pex in the walls and copper on anything exposed. Is this o.k.? I really don't want to have to cut too many holes in the walls seeing as I will be doing the work myself. Is pex a turnoff to new buyers?November 18 2010 - Los Angeles0YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
