Hi, I have a leak in a galvanized half inch pipe, and I want to replace some of this old pipe with pex. I will try to unscrew the 90º elbow (as in photo), and connect the pex directly to the threaded galvanized pipe. The problem is the fittings for pex are brass which isn't compatible with the galvanized pipe, but I have doubts about using dielectric fittings after reading some opinions online. Do you know of some good way to make the connection that would be ok for a potable water supply?
But If for some reason, I can't remove the old elbow, I was thinking of cutting the half inch galvanized pipe and using a coupler (rubber?) fitting to connect to the 20mm pex, but I suspect that those couplers are not approved for potable water? Thanks.
