I have a leak spraying out of my main water shutoff coming into the worries it only leaks when u turn it to shut it off (it is open all the way right now and not leaking). The house is plumbed to be a maze of galvanized pipe. I am not comfortable with that as if something were to go wrong I don't know how to fix galvanized and I cannot afford a plumber. So my objective is to cut the galvanized out before the main shutoff, convert to PVC and replumb ( I have used PVC many many times before and am very comfortable using it). The only hangup is I have never had to connect PVC to galvanized and don't know if there are special fittings for that. Someone suggested a compression coupling, but I didn't think that would works since it will be under pressure. Also, I do have the town's number to call and have water shut off before doing the work (i know someone will remind me on I do not want to leave the galvanized either because I do have some rust deposit coming from the pipes and I know swapping to PVC will help. Thanks in advance!

First you need to use CPVC no PVC. At least for the hot.

To make the transistion you use a PVC fitting with a MALE pipe thread that you screw into a female pipe thread on a valve or a coupling.

I am not sure about the problem with the shutoff vavle. If it is leaking around the stem or won't completely shut off the flow.

In either case the valve can usually be fixed. If it is leaking around the stem it sometimes it just need tigthen the packing bonnet.

But I would replace it with a full port ball valve.


Or if it is not practical to replace the existing one then install the ball valve downstream.

Sorry for not using the Cpvc. I would use CPVC for all of it both hot and cold. I plan on installing a ball valve as the main shutoff. Thanks much!!!!!!!
