p trap in bathroom?

lance70 · 07-02-2010, 09:43 AM

Hello, I'm trying to replace our p trap in the bathroom and we have an older house with the metal pipe coming out of the wall. Is there a fitting you recommend for connecting to this pipe or will the plastic fittings and plastic washer work that comes in the kits? Thank you!

Use a brass slip joint nut not plastic

Thanks! So it's okay to use the brass slip joint nut with the plastic pipe or should I use all brass?

Yeah that's fine. Metal to metal, plastic to plastic. Use some pipe dope on the threads.

ohhh okay, thanks! one more question, what about the pipe that comes down from the sink itself, the top part is medal and has threads in there, should I use a brass pipe to thread back into that, so I have medal to medal? Then from that pipe I go into the pvc with a plastic nut? Sorry I just want to do this right, wife and I really appreciate your help!

Your new plastic P-Trap will fit over the chrome tailpiece that comes down from the pop-up assembly. The bottom of that should just be smooth (no threads). The new plastic nut and washer is like a compression fitting. Will seal against the chrome. The top part of the tailpiece threads into the pop-up assembly.

Question for you actually - Is the chrome tailpiece missing from the pop-up assembly?

is that the piece with the threads? The male fitting? I do have the original piece if that's what it is. I wasn't sure if I should replace that too since I'm doing the other pieces or just leave that chrome piece screwed in?

Yes, the chrome piece with fine threads at one end will screw into the bottom of the pop-up assembly. If it's in good shape, not rusting out, I would re-use it. If you've taken that apart use dope and tape before you thread it back in. Use your hand not a wrench.

Make sure your new plastic washers are facing the right direction. The beveled end will be facing and away from the nut.
