No Hub Coupling Under Slab Floor

Sum fl i used a no hub coupling proflex the one with a rubberized sleeve and a rigid metal sleeve outside of that tightened by two screens.

No hub coupling under slab floor. Engineered to connect no hub cast iron pipe in applications replacing the less efficient hub and spigot. No hub rigid coupling can it be in concrete. Strong back rc 5000 series couplings. A mechanical joint shielded coupling for hubless cast iron pipe and fittings shall have.

1st question is yes install a pvc wye use fernco or plastic to no hub adaptors with no hub bainded couplings for the connections. All of these are generically referred to by all the plumbing supply.

No hub couplings.

The no hub coupling has a patented shield design that provides maximum transfer of pressure from the clamps to the gasket and pipe. The coupling is about two inches below grade and i will be filling back with some concrete. Engineered to connect no hub cast iron pipe. As defined in the uniform plumbing code section 705 4 2.

Flexible coupling is shielded flexible coupling. Connect service pipe to any solid wall profile closed profile or corrugated pipe. Next questions clamps are non corrosive but pipe is not so it can not be directly embedded in concrete anytype of wrap will do you only need the barrier between the concrete and pipe. Everyone says proflex pvc to pvc shielded couplings are the way to go for under slab wye tie in for a new basement bathroom but i keep reading they are not rated for direct dirt contact as they will be under at least 12 inches of dirt with a 4 concrete top poured back over them.
