bathroom remodel need to bury copper
I am in the middle of a major master bath remodel. I removed a old fiberglass tub and installing a freestanding tub. I need to re-route the copper lines down into the wood sole plate (non bearing wall) and over into the tub area. The tub filler is also freestanding. The floor is slab.
The floor already has an area ripped out for drain pipe(which also neds to be extended to the center of the new tub).
The plan: route the copper down through the sole plate into the slab and run in along with the drain. The new lines will be soft copper and all fitting above slab. The copper will be fitted with Armorflax sleeve and heavy duty plastic.
My question:
1. Does the copper need to be set below slab (into dirt)? If I dont, and set the copper lines say half way into concrete slab then repour the area with quickcrete, will I comprimise the copper and PVC pipe(expansion/contraction) crush the pipes,etc.?
2. drain pipe, does the p trap need to set right at the drain the nslop to the plumbing stack?or can I leave the p trap where it is and slope it over approx 3 ft off the side?
thanks

can you run the pipes for water up and over or through the wall to the other side if you put in slab use tye L soft copper and if not in dirt I would put insulation on them . the drain is two inch and the p trap is just below the drain inlet
My "safe" option is to run the copper pipes along the wall(exterior) near the floor and make a box so the copper lines are above the slab. The tub filler would sit on this tiled box. This box and tub filler would sit behind the tub. Kinda feel like its cutting corner but a little nervous of burying copper.
other input?

Why not use PEX? Much cheaper than copper, easier to bend, and they put it in slabs all the time for heating.

if you use pex uderground you should put it in some sort of conduit because if there is any contaminet in the soil it can migrate through the pipe into the water
Didnt think of PEX, as far as the dirt we have here(Phoenix) we have alot of alkalinity.
Interesting to see the effects.
thanks
