Hello,
I had a question/concern. I have a 60 year old house that I recently had the majority of the plumbing replaced on. The house is small with just one bathroom/kitchen/spicket/utility tub to supply. This weekend, I had everything replaced but the horizontal pipes, since they were all in good shape and made the job much quicker/easier (cheaper). The charge was only $1200 to install the new copper, and now I'm a bit concerned after reading about connecting galvanized pipes to copper. There are four spots where this was connected directly - the kitchen (hot/cold) and the shower (hot/cold). The water main and the water heater both have dielectric unions to prevent the materials from corroding.
Anyway, everything is working great and in most areas, the pressure is noticably better. I've read in some spots that connecting the two metals will cause the galvanized pipes to deteriorate quickly, even if the entire plumbing system is grounded. I have seen several cases like mine where the connection was done in the same fashion (directly), but reading phrases like "rapidly speeds corrosion" has me a bit nervous and wanting to just have the remaining pieces converted.
Any suggestions/input would be greatly appreciated.
Thanks! Eric
