Hi. Quick question about joining copper pipes and other copper plumbing
fixtures. I know sweating is an obvious way, but last year we had to have
the shoe on our drain line from our bathtub replaced as it was leaking onto
the ceiling in our den. I swear the plumber used some sort of goo (sorry,
not a technical term to join the copper drain pipes and the new shoe, I know
for a fact he didn't sweat them. I am asking because I have a 1 1/2 inch
copper drain line running from my laundry sink, and the tailpiece that
connects the drain line with the trap is corroded beyond repair (I can't use
an of the rubber sleeves, etc. it is too weak). Is there a way I can join
a new one (metal) to the copper drain without sweating it since it is only a
drain line and not under pressure like a supply line? Or even better yet,
is there a way I can go from the 1 1/2 inch copper to a pvc tailpiece that
would connect to the trap? I know there are pieces to go between copper and
pvc, but I don't know if they are made in 1 1/2 inch size? Thanks for any
help or ideas anyone has.

Use what's usually called a "fernco" adapter. Hook on to the drain pipe
that the trap ties into, then install a new trap and tailpiece. If your
laundry tub is the old cement type, then you can probably put another fernco
on the threads that the tailpiece ties on to. Get the 11/2" pipe X 11/2"
tubing size. It's probably called a fernco trap adapter. Make sure you cut
out the section that's too weak to work with a fernco.
If your plumber used some sort of goo, then he really didn't repair the
problem (though, I've epoxyed some things myself before).
Tell me if this is permanent, or if I should change it sometime. I had
to hook on to a meter yoke that was formed out of 3/4" OD copper. I was in
a pinch, so I noticed that 3/4" OD slides tightly inside 3/4" ID tubing, so
I reamed a piece of tubing and soldered. Then I soldered the 3/4" ID into
the ball valve. I turned on the water and everything seemed fine. I even
shook it vigorously.
Must I track down a reducing coupling, or will it be fine???

as long as the ends were cleaned well, but not beveled or unevenly
reduced, your solution should be fine, and permanent
