I have a horizontal run of cast iron drain pipe underneath my basement slab (this section of slab has been removed) that I have cut and want to create new drain runs from PVC (for a bathroom). Before I have all my pipes laid out and refill the area with new concrete, I had a couple questions:
1) Where I have cut the cast iron pipe, should I apply some type of primer to the bare metal cross-section to protect it from corrosion?1) Can the no-hub/hubless/Fernco connectors that have the solid stainless-steel band be embedded either partially or wholly in concrete? Should the no-hub connectors be protected from the soil and concrete by surrounding it with gravel or wrapping it in visquene or something else?
