The U trap under a sink disintegrated leaving its threads rusted to the female nut on the horizontal pipe.
So I have to install a new horizontal stub to the wall.
I've unscrewed the nut on the wall side, and I find there is a nylon (?) seal bushing inside the waste pipe, stuck in with 40 year old plumber's putty or something.
I don't want to wrench the pipe because it will disintegrate making a mess. And I don't want to stress the joints beyond -- I can't support it because its inside the wall.
Can I use flame without melting the nylon / plastic ?
I cracked the old U when I tapped it doing a trial fit of the new 2.5 gal water heater. Very happy to have it happen now instead of noticing a stink at some point in the future.
But I AM getting tired of something breaking before I've finished fixing the last thing. Got my Uponor catalog today with part numbers for the PEX repiping job so I can start to get started on that... after I finish pulling electrical wiring... and if my good computer is successfully fixed (pulled a socket off the board, waiting for conductive epoxy to dry to see if I succeeded in salvaging a $300 laptop board...)
