Below is a pic of the drain pipe under my master bath vanity. My drain pipes are made of ABS.
About a 1/4" from the face of the escutcheon, someone has previously welded a straight coupling, and for God knows what reason, the trap has been glued together.
I am installing a new base cabinet and top, and the drain needs to be repositioned.
Should I cut along the yellow line, remove the escutchion, and slip on a Fernco coupling?
Or can I make a cut a little further out, and solvent-weld a PVC street coupling into the inner ABS pipe?
Orange has an "all-purpose" cement which works on both ABS and PVC, but it doesn't say on the label if it's okay for to welding together two different plastics together.
Just trying to ascertain a legitimate way to do this - preferably without tearing into the wall.
Thanks in advance,
Not a pro, but happy to share my lessons learned whenever I can. This forum has been a fantastic resource along the way.
There is a transition glue available, but in your case I wouldn't use it.
Cut on that yellow dotted line, and lose the bell-escutcheon, bore out the back of the cabinet enough to fit a new ABS coupling.
I'd be tempted to use a spigot-trap adapter, and use a tubular trap so you can avoid problems like this later on.
