In my situation there is not enough room between the galvanized fittings to cut and have a stub big enough to use a no-hub adapter. I am working with a 1-1/2" waste line. I am wondering if I can connect one side of a No-hub adapter over the female portion of a galvanized fittings (maybe use a 2" to 1-1/2" no hub?) And the other to the PVC? Or am I not allow to put it of a fitting and it NEEDS to be on a "regular" section of pipe? (the "regular" section is under the floor on the second story and I don't want to pull the floor up).
Or should I try using a PVC 1-1/2" male threaded adapter to connect the PVC to the female end of the galvanized fittings (could someone recommend the correct adapter?)
Thank you for your help in advance!
