All,
Thanks for the feedback. In all things I do I want to do it right, and at this age am not afraid of doing extra work to achieve this end. I'm really grateful for everyone taking the time to help.
That being said-
Aside from my tireless efforts to solder the cheap chrome elbow to the waste pipe in the wall, all other advice was from 'experts' with at least 10 years from HD and my personal plumber. While an expert is a subjective term these days it seems they were misguided. My plumber said NJ laws now allow the boot in this scenario. While this may be a not too expensive job to hand over to some 'pro', I figured aside from the wall pipe to the elbow, the rest was within my 'competence level' as I've done a a few faucets and drain installs. Plus the plumber I used stopped by to remove the soldered trap and has since gone on vaca for a few days.
HJ - Moderator and Master Plumber - totally respect your position and expertise.
Small note, your reply below was mistakenly to Reach4 but assume it was meant for me, the OP. I was offended actually by this post at first, but figure you just loathe anyone trying but not seemingly having the expertise at the time and making a mess of things. Actually from post 14 is where is got advised from others in store etc. and just carried on from there.
I've gotten (too much misguided) advice from a number of folks in store, but this thread knows the best story with pictures. I would like to fix/replace the waste pipe in the wall ($$ factor for me now) but for now can I use a banded coupler and connect the trap to the drain w/o the flex crap as it might still be offset? Please be specific.
TIA
HJ - The "proper thing" would be to quit jacking around with that piece of pipe in the wall and install a new one with a proper straight tailpiece. Everyone wants to "do it themselves", but you violated my first rule for doing so. You were supposed to stop at least a minute before you reached your level of incompetence, but you kept on going.
