    I would use copper, but I know with copper almost as costly as gold now, you might want to use PVC. As far as the depth is concerned, it needs to be below the frost line, which I doubt is extremely deep where you are. Why don't you use the depth of the old line as an indicator?

    I would go with 1" PVC buried as deep or slightly deeper than the old line.

    I'd use 160 or 200 psi rated PE pipe that commonly comes in rolls up to 500'. It does not have any of the problems copper or PVC do, and it and the two SS male adapter fittings and 4 SS hose clamps you'd need are very affordable.

    I was thinking of going with 3/4" PVC.. but i'm not sure about the psi.. the pipe I looked at @ Lowes were 200psi and 400 psi... and they came in 10 foot sections..

    Default pipe

    Use only schedule 40 PVC. PVC is pipe size, PE is normally copper tube size so it is much smaller internally.

    The PE used for water lines and well/pump installations is IPS; only PEX etc. is CTS.

    PVC usually has expansion/contraction problems and breakage is much easier than with PE pipe plus PVC requires a coupler or other type joint every 10-20'. PE requires no joints and only one conection on each end of the run. And the friction/pressure loss is less with PE pipe than any other material.

    I would go with 1" P.E. It's what most of the older houses in the small towns by me ran from the mains. A lot of it is 30 years old and no problems yet.
