    Recently I noticed water on the floor in my 1/2 bathroom. My question is can I replace the sink trap and the nut that is pictured or do I need to replace the plumbing in the wall too?

    Yes that nut should just spin right off. Plumbing behind the wall should be fine. Looks like it’s been leaking for some time.

    If it has been leaking for awhile it just started to leave clues on the floor lol. Should I replace it with metal or go PVC?

    You can see from all the junk on the pipe it’s been leaking for awhile. You can use ether. I normally use PVC on my sink installs.

    Those chrome traps are notorious for leaking. I’d switch it out for pvc or ABS

    We always use pvc whenever we install or replace sinks. You avoid the corrosion that can happen with metal.

    Did you change the trap? The trap doesn’t look as bad as the trap arm.

    Usually those nipples rot out and you have the challenge of cleaning it out of the threads. My plumber has a larger tap for that occasion. I don’t and when faced with the situation I tephlon the crap out of a PVC adapter.

    It really is an easy job, take old off, clena it al up, then install the new one and check for leaks.

    What’s the best way to clean off all the corrosion on the metal pipe?

    I use a little wire brush and dig the blade of a untility knife through the grooves.

    I still think the trap is the least of the problem.

    Get a little bucket or paint pan and put under the trap because it will be full of water. I would definatly use pvc .

    I’m sure your talking about the pipe in the wall. I would just use a wire brush and brush it off.

    This reminds of the traps at my Grandparents place. I pretty sure they never had any problems with them.

    Wasn’t uncommon for brass traps to rot out the galvanized nipple coming out of the waste line.

    I hope you don’t have to deal with that trap arm………

    Another hiccup I have run into is the sink drain location. Some of the older wall mounted sinks had tight bend/ close quarters traps that won’t fit s modern plastic bend without killing the nipple altogether and running an adapter right to the wall.
