How to attach 1 1/2 PVC to P trap coming down from sink drain
Hi.
I put in a new sink/vanity top combo and cut off the old DRUM trap and now have just a 1 1/2 PVC stcking out from the wall under the sink. What do I attach to this 1 1/2 PVC so that I can attach it to the P trap?
Do I have to use cement and primer to the PVC or is there a way to use some type of compression fitting?
New to all of this, but having fun doing it!
Thanks

You probably will want the appropriately named trap adapter.

They make a couple sizes, depending on the size of slip joint trap you are using. Bigger is better.

Thanks. So will this allow me access to the 1 1/2 PVC that comes out from the wall (Drain pipe) in case it gets backed up someday in the future? I would guess that I'll have to cement that in? Do I use Primer with clear cement?

Yes.....you need to use primer and glue. The horizontal drain line from the trap will slide into the trap adapter. It can be removed in the future. A normal clog would usually involve just taking the trap down.

Thanks.
So the TRAP ADAPTER will glue (weld) into the 1 1/2 PVC coming out from the wall? Then the horizontal drain pipe that comes from the P trap will SLIDE into the Trap adapter and use a nut and washer (compression fitting)?

I used a flexible P trap (accordian style). It seems to work fine and there are no leaks. Are these ok? I heard they weren't code or something?
