    How do I go from an odd size drain to a standard?
    Hello,
    This is my first time asking a question here so please be patient with me if I don't explain myself well.

    I had new kitchen countertops and sink installled yesterday and was hooking up the drain traps. I was going to install a regular inch and a half P trap. When I removed the old one, it appeared to have a two inch nut on it connecting it to the drain. The only thing that I could find that would fit was trap that was made for a mobile home but it reduced it to an inch and a quarter instead of inch and a half. The inch and a quarter does not fit the new sink drain. The old trap looked to be PVC that was all glued together. Since the sink is a different size the old one will not work. Is there a way to go from the 2" nut that attaches to the drain going out and end up with a inch and a half so I can use regular slip nut type fitting?

    Thanks everyone in advance.

    You're OK! Your 2" compression fitting, (see image) has a 2 X 1 1/;2" gasket,( that's the blue thingy) that will accommodate your 1 1/2" trap just fine.
    Go i8nto a plumbing store and ask for a 2 X 1 b1/2" nylon compression gasket. That will fit both the 2" compression nut and the 1 1/2 trap.
    Good luck, Tom

    Just FYI...

    In my area you would ask for a 2"PVC x 1.5" compression style desanco fitting

    Just one more way to say it in case the guys at the supply house decide to mess with you... ;)

    Good luck!
