   1. You can use whatever fittings, or combo thereof, you need. So long as the joint is tight, it doesn't matter whether it's threaded or glued.

   2. Check with your AHJ. In my neck 'o the woods, glued transitions are not allowed, period. The inspectors require Ferncos for transitions. Always use primer.

   Are they specifying brand or style?

   Shielded couplings inside, non shielded outside is the UPC.

   Heck, if it just dumps into the crawlspace, you don't need any connections, do you?

   Don't laugh at that one...my little brother who thought he would get rich with rental houses tried to fix a plugged drain from the bathtub. He went in the crawl and saw a plug in the iron pipe, removed it to run a snake, and all the backup drained into the crawl. HE LEFT IT!! And when his tenat complained of the smell, weeks later he ask me to help him find the problem.

   One look, or wiff, in the crawl showed me the problem.

   I sent his skinny butt in there!!  And our father was a plumber!

   UPC allows either, but no transition glue, but that is changing not too far in the future.

   But threaded does not mean UNION. Those two piece plastic traps that are joined by a union must be accessible.
