Hi--I've been here before over the years but haven't really established myself. I have been a kitchen and bath remodeler for several years after mostly building new construction. I've been around an awful lot of "interesting" plumbing situations, to say the least, but I have never seen anything this unusual.
Situation: replacing a sink/disposal. Problem: 1 1/2" pvc threads on new trap simply DO NOT mate up with threads on old elbow coming off the y pipe. I have looked at this from every angle, and played with all kinds of possibilities, but it comes down to this--did PVC manufacturers actually make a change within the last 25 or so years, and make these things slightly (and boy, do I mean slightly) different? the new part matches perfectly to threads on other fittings I have, and the old one does not. The new pieces are definitely wider, meaning stronger, than they used to be.
I'm hoping all the old hats will chime in and tell me this is common knowledge and the parts are available, but thought this to be so strange since the pieces look Identical, and everything is right, except they won't work.
Help!
Thanks!
