Hi all. I just bought a 1980 mobile home and am changing out the bathroom faucets. It appears that the drain pipe is 1 3/4 in black pvc. But I cant find a store that carries it. I really don't want to cut it all out and replace it if I can avoid it. Any help?

Are you sure it isn't poly pipe?

I just left home depot and they said it is too big for 1 1/2 and too small for 2 inch so that is why I said 1 3/4 inch

Can you take out the drain trap and take it to the store, show them what you have, tell them what you need? If you are changing the faucets why are you also changing the drain? Are you measuring the 1 3/4 inches across the outside of the pipe or across the inside dimension?

Take it to a plumbing supply house. That will save you from the folks at the big box store giving you the wrong information.

I am going to try to post a pic of the drain. I had to loosen it to install the new drain pipe that came with the faucets.

Appears to be standard 1 1/2" ABS pipe. Looks like the union is missing from the trap. I'd cut that trap off, glue a trap adapter on the stub and use a 1 1/2" tubular p-trap in it's place.

Thank you for replying. I thought it was 1 1/2 too but went to home depot and bought a 1 1/2 ring to screw the pipe together and it was too small so I bought a 2 in and it is too big. So that is where my first post of 1 3/4 in came from.

But yes all I need is the ring to attach the two together. It was either glued on or something so we cut it off. The rest of the P trap is fine but just the threaded ring is no good.

Are you looking for a nut to connect the u-bend to the trap arm(red box)? That nut is not a standard size and is not replaceable. You would need to cut out the trap assembly and replace it.
