Rerouting water supply into house

[Christopherjm]

Hello, I'm really glad I found this forum and I'm hoping you can help me clear up some unknowns, so first off, thanks for your time and sharing your knowledge.

I want to reroute the water supply into my house starting after the pressure regulator and going around the side of the house and into an exterior wall. The house sits on a slab and running it under the house is not an option for me.
I've been advised to use Type L copper, but that's where my knowledge ends.
I'm not sure how deep to bury the pipe, or when the piping comes out of the ground and into the exterior wall, if it's okay for copper pipe to be exposed, or if I have to use a different pipe (PVC, galvanized, etc.).

Thanks for your help.

Where are you located ? because the ambient temperatures throughout the year matter when you run pipe exposed on a building. Plastic pipes for domestic water are never to be exposed to UV. The uniform plumbing code allows copper type M for residential piping underground outside of the building. It must have minimum 12 inches of earth cover but that’s only if you live in a climate that does not freeze

I'm in S California.

Bump.

I've made some headway. Learned the underground joints need to be brazed instead of soldered.

Need to find out:
How deep to bury the copper pipe
How far from slab foundation
Can the pipe rest on the soil or does it need to be on sand or something else

Thanks guys

You can lay the copper pipe right in the ditch. Use K copper and be careful that you get no kinks when rolling it out. Depending on how far you are going you can get a roll in different sizes and then you have no fittings underground

In most all the major cities of California we use the CPC (essentially the UPC).
That allows soldered joints in the ground outside the building.
Copper type M is allowed for residential outside of the structure.
L is thicker and more durable but not required by the CPC.
We only use K for medical gas out here.
If you are not experienced and trained to solder, I would absolutely not recommend a do-it-yourself attempt. There is a lot to know and many pitfalls.
Save money by excavating yourself (cover the open trench with plywood) and hire yourself a licensed plumbing contractor.

Safe excavation proximity to slab foundation: Safe excavation is based on a 45 degree angle away from the concrete starting at the low point of the footing.

Thank you. There's no denying there's a lot to know.
