Re: Main Waste under footing?
From the Commentary in my previous post:
"A relieving arch or a pipe sleeve can be used to provide this protection."
That, to me, means that the pipe used for the sleeve (used to provide the protection intended - "must be protected structurally from any transferred loading from the foundation wall or footing" - would thus need to be at least sch 40 steel pipe.
Even PVC, being must stronger than PEX in providing protection, *will not* protect from the loads being described.
