Hello all,

I have been searching on the Internet to find out if I can use PVC to replace my resting steel main water line. So far nothing definitive came out.

I live in San Jose California, so cold weather is not much of a factor.

San Jose has a nice office that you can all to find out the
answers to such questions. Or you can call valley water (or great oaks
in parts of south SJ) and ask them.

I'm aware of at least one home in SJ that replaced the
feeder from the main water valve to the house with 1" PVC
35 years ago.

My main goal is to get something that does not rust.

Are you talking externally or internally?
