    Default Which coupling for 3" PVC to 4" Cast Iron

    I need to connect my new 3" PVC drain line to the old 4" cast iron drain. The pipes are on the horizontal in the basement. Which Fernco coupling would be preferred? The 1056-43 Flexible coupling or the ProFlex 3000-43 ? It looks like either coupling would accomplish the same thing but it seams like the ProFlex would be more resistant to shear since it's banded.
