Hello all.....

Please bear with me, but I've got a very basic question......

I have 1-1/2 inch PCV Wall Tube from behind vanity. I am trying to connect Plastic P-Trap to the PVC. The PVC has no threads......just straight PVC coming out of wall.

What is best way to attach connector? 1-1/2 inch connector doesn't seem to fit correctly? Is the term "Desanki" familiar? Local plumbing supplier told me that I "cut off the Desanki", when I shortened the wall pipe......so now attempting to reconnect, but standard HD plastic doesn't seem to be a 'tight' fit? Don't want a leak problem later?

What am I doing wrong?

Thanks for info...

-Bill
