  • Want to switch from copper to pvc

    I'm installing a basement bathroom. The current water lines are 3/4"(I think) for cold and 1/2" for hot. The existing lines are copper. I would like to tap into the copper and convert to CPVC. What size should I go with for each? I'm putting in sink, toilet, and shower. Can I go to 1/2" for both?

    Thanks

    Provided your pressure is ok 1/2" for both should be fine.

                  It wasn't you. It was Miller's question.

                    NONE



                    Especially when there is no problems with the current copper piping in the home.


                    One thing is for sure,

                    When homebuyers, real estate agents, insurance companies, real estate appraisers see the commingling of numerous or different pipe systems in a home, meaning the existing piping is one type and the add-on work is done in another,

                    it's frowned upon, it takes away from the original piping *doesn't matter if it is pex/copper/galvanized/cpvc* and lays into a casting doubt that the work is done by a professional or not.

                    Switching to another product for improvements spells the reasoning of inexperience to follow what's there or following the dreaded cost factor.

                    If you're going to work in a house piped entirely in CPVC, keep it that way when you add to it.

                    Same goes for whatever piping goes in there. But when you mix it up, it now becomes the questionable work practice of someone saving a buck and that theory usually proves haunting when **** goes wrong and the last homeowner is long gone, not responsible for that half ***ed glue joint or not tightening a water line connection tight enough.

                    I swear if some people could get away with it, they'd use garden hose in their home to save a buck. I would know, work for these types on a regular basis.

                      Listen to the experts and don't make your house look like crap. Have you checked to see if you need a Certificate of Occupancy for that bathroom? Most towns will want the blessing of a licensed plumber and inspector that the work was done to code, things like proper venting of the toilet! Why not hire a pro to rough out the plumbing and save money on installing the fixtures and tiling? Don't cheapen your investment and open yourself up to legal problems to save a few bucks.
