      I’m running a 1″ copper supply line up through a concrete slab. What do you recommend to use to protect the pipe from the concrete.

      Is this recommended for PVC also?

      Thanks,

      Jim: If the copper is going to be used for water distribution, it is common practice where I live to sleeve it along it’s entire length with black poly irrigation tubing,
      and turn it up through the concrete pour. This works out quite well when the need to repipe occurs…it is a simple matter to pull the old copper line out and a new one in simutaneously. As for the PVC: If it is going to penetrate a bearing wall or foundation, it will require sleeving with a metal pipe(sch.40)
      that is one pipe size larger than the carrier pipe. The annular space between the inner and outer pipe needs to be made rat and water proof. If it is simply going to be stubbed up through a poured concrete slab, it requires no wrap or sleeving.
