Undeground Separation - Water to Drain

[THomes]

I am relocating a sink to a new island in the kitchen and need to sawcut the slab to run the plumbing. Can anybody tell me if there is a code requiring a minimum separation between the hot /cold water and the drain line? I assume I can route them in the same trench.

Thanks!

they can not touch, my opinion would be to insulate the watr pipes to protect them from rocks rubbing or concrete

Thank you Frodo. I will most certainly wrap the drain in foam and cover the copper lines with Armaflex. I just wasn't sure about needing to have them a certain distance form one another.

Appreciated!

the drain does not need to be wrapped. sorry if i implied that, just armaflex the hot/cold
