When replacing threaded fittings what should one use to ensure good seal?
All my prior experience with plumbing was with PVC using two part cement and Teflon tape on small stuff.
Use a good quality pipe dope. It doesn't harden and keeps corrosion away. I can't remember the name but there used to be a brand that was greenish in color and used by a lot of pros.
If you have to make a splice and I'd say you will it would probably be best to make it on the horizontal section and replace the 90 with a brass fitting also.
