    Default Copper to PVC

    I have a new bathtub installed, and I am trying to connect the plumbing underneath. The current setup is a copper 1.5" ptrap with some threading on the end.

    I went to Lowes, and found a PVC fitting that would screw into that. I just want to know if I screw it in and done, or if I need to apply an o-ring or glue or something to get it going.

    Thanks for the help!

    Teflon tape. If you can find the stuff in the pink roll, it is thicker than the regular stuff and is less likely to tear apart on the threads.

    there is an O-ring that goes around the pvc pipe and sits under the nut. that O-ring gives you your water tight seal. make sure the O-ring, the tapered part, is facing down into the trap. no teflon tape is needed at all on the connection.
