So here's the setting:
So my question is pretty simple, what material should I build my manifold out of? PVC? Copper? Galvanized? If PVC, can I use those cheapo PVC ball valves, or do I need to go all in on the brass versions? This is the southern side of the house, so it'll get a lot of sun so if you say PVC, I'm sure I'll have to paint it. Any suggestions on insulation so I don't blow things up on one of those infrequent Tucson "deep freezes" (where it get's into the 20s at night Brrrrr.)
P.S. For those with a keen eye, I know that's the wrong type of backflow prevention device for the irrigation system in the second picture. It's all getting ripped out and replaced anyway..
- I'm in Southern AZ. We get about 5 nights a year below freezing.
- House is slab on grade with flat roof so changing any plumbing inside the house is a PITA.
- Currently the house is supplied with 1-1/4" PVC underground, transitioning to copper as it comes out of the ground, through the main shutoff valve and into the house. See pictures here.
- I've got a trench dug to put in utilities to a future outbuilding. At some point I'd like to put in a water softener. Frequently those are put outside down here due to #1 and #2 above.
