Scott replacing part is quite possible. I had replaced what was in my
basement and let the risers in the walls and other areas for later. Fittings
to go from pex to copper can be soldered or compression so anyone can do it
with a little diligence. The assortment of compression fittings is really good.
Last year I installed a manifold for all my lines with each having a
shutoff on the manifold distributor panel. The main lines to it are all
compression from the meter service. Matter of fact, all fittings on the
manifold are compression and are blind friendly along with copper to pex
compression fittings. The standoffs for mounting are also quite easy to
install. Depending on how much you want to do will determine expense according
to which fittings you choose for your own personal convenience.
