I just recently purchased a house that was built in 1979 with galvanized plumbing. The water main just outside the house looks like this:
I'm planning to replace it, but I want to make sure it's done right. Disassembly isn't going to be that tough (cut the PVC, spin the tee off the stub), but when I put it back together, I want to make sure I have the right fittings in place.
My thoughts are to do the same thing, but I'm wondering if I should have at least one union in there somehow. I was considering having one between the stub and the tee, then one between the shutoff valve and the tee, but I have a feeling that may be overkill.
Any advice on this would be much appreciated.
