Replacing bathroom sink - questions about tools, drain pipe


I'm replacing my bathroom sink and vanity & have questions about the drain pipe (I already have info about the water supply lines):

I'm going to use new PVC piping; assuming the following: Wall pipe --> drain pipe --> p-trap --> tail piece --> pop-up assembly
Therefore, need to buy p-trap kit and pop-up assembly (unless, of course, need extensions)? Anything else in terms of pipes?

How do you know what diameter size p-trap kit and pop-up assembly to buy?

If 2 pipes have the same diameter, how are they connected -- I know slip nut but does one pipe have to fit inside another?

If one pipe is smaller diameter than other, I have to use a reducing slip nut w/ a reducing rubber bishing?

Assuming I should buy a bunch of extensions, elbows and slip nuts and return the ones not used?

Good place to buy all this?

Most faucet sets come with a pop-up---

All vanity drains are 1 1/4"---new vanities tend to be taller than the old ones--so this is what you need---
(all 1 1/4")
One-tailpiece extension-one P-trap set---possible a 1 1/2" nut and a 1 1/2" to 1 1/4" reducing washer washer to go into the wall---

What size is the wall pipe ? That threaded fitting is called a 'trap adapter'---if it's 1 1/4" you are not going to need that reducing washer and larger nut---but you will need another 1 1/4" nut and washer.

Replacing bathroom sink - questions about tools, drain pipe


Thanks, Mike. I'm trying to gather all the info I need for when I get the time to do this (I bought the vanity w/ sink + the faucet). I've watched a few videos on youtube and, in another post, someone said that I would need primer and glue. In the videos, I haven't seen anyone using glue or primer so ... And, I am still unclear about how 2 pipes will connect if they're the same size: e.g. if I cut a 1 1/4" PVC pipe and I need to connect it to another 1 1/4" PVC pipe, I assume just one of the pipes has to be threaded? And I just connect them by using a washer and a slip nut that goes on the pipe with the threads? The pipe without the thread doesn't fit into the pipe with the thread?

Take your self to the store and look at the parts---the P-trap and extension are larger at the top so the end can slip inside--the tighten up with the plastic nut---This will also give you some adjustment as the 'pocket' is deeper than needed---

OK. And what about gluing? I've watched some videos on bathroom sink drain pipes and didn't see anyone use glue. Is it needed?

No glue needed---you will need a small tub of plumbers putty to use under the top chrome ring of the pop-up.

If it was glued there would be no way to disassemble it to cleanout the trap and drain.

You will need to glue on a trap adapter at the wall if you do not currently have one.
