Black pipe to PVC connection
Black pipe to PVC connection
(OP)
Hi,
On a design-build project, the DB has proposed using schedule 40 pvc pipe for the plumbing works. The MEP review consultant recommended schedule 80 pipe. As a compromise, the DB has offered to use schedule 40 black pipe (ductile iron?) with schedule 80 PVC bends which the reviewer has said is ok. This just does not seem right.
Any comments?

In any case, I agree with the young cat that supplying a stronger metal pipe but with weaker pvc at the fittings (if that is what they are talking about), is a quite unusual (and perhaps as he infers not normal/or best practice).

Thought this didn't make sense. Is would seem to me that sch 80 pvc pipe would be much cheaper to install than this "black pipe" so the material cost of the iron pipe must be significantly lower for the DB to be recommending its use.
