UPC requires a support with in 18" of a No HuB band. Over time your PVC/Cast Transition Bands will pull and sag.
That is a biggie here with our inspectors. Have to go out of your way sometimes to get the right amount of hangers in the right spots. Lots of extra strut in bar joists sometimes.

On LI NY. Certain towns you must have cast iron. We use transition bands on sizes 3" and up. The difference in size with 2" and smaller pipe with pvc, cast, and iron is smaller then the tolerance of transition couplings engineering. Now that is not going to fly but with me it does. A 4 band husky clamp is better then a fernco. And most supply house do not carry pk22's let Long 112 also. Those are 2 inch cast pvc x cast adaptors. The no hub works well. Yesterday did a repipe. Then got a call later that day. A 4 inch long sweep had hairline crack. And developed a leak. Pulled and replaced in 12 min. 123. 1 of the exact reasons why I use cast. Also I like to try to standardize as much as possiable. And for that. Around hear there is only one product that is always allowed, in any situation I come across. Cast is the answer every time. For 2 inch and smaller depending on the job but still 60% of the work is done in cast also. It is the same reason I use propress. We use copper copper copper. It is always code compliant, ridged allows for an easy install. Much easier to brace and work with. Espically when u do not need a torch.

I like the no hub cast pipe,in bldings and houses unfortunately it is not cost effective in my area,what I love about cast iron is you don't hear a waterfall each time a toilet is flushed ESP. In a basement,I love how you don't hear water gushing thru the pipe like pvc,also I love how cast iron looks after it is put in,nice and neat and strong,good job I say,collect your money and go to the next one
