Welcome to IRV2! We're sure glad you joined the gang!
That may be a tough one if you've got all the pipes apart! Sure would have been great if you had taken some pics before starting the repair.
Are you at a campground or somewhere that other RV'ers may be able to help you?
Good luck, happy trails, and God bless!
