I'm replacing some galvanized 2" drain/vent. Comparing these two types of couplers, is there a time I shouldn't use one over the other? When piecing last bits together it is not possible to use the one with the rib on the inside mid section. Seems like it wouldn't be a problem on the vents. Is that true? And what about elsewhere?
Thanks, Clark
