Vent Issues

I am installing a Zoeller Ejecter pump system for a basement bath. I need to tap into my 3in copper vent and connect to a 2 in pvc pipe. Any ideas, because the flexible rubber tees seem too large for the copper. I think they are designeg for cast or pvc.

try posting your question to the plumbing forum, you will find more answers there.

Cut a tee into the 3" using Fernco Proflex Couplings # 3001-33

This vent must be tied in above any drains on the 3", It must be 6" above the flood rim of any fixture that drains into the 3".
