    Hello,

    I took the trap off my bathroom sink and it was so old that it just tore the metal when I tried to put it back on. So I went to the hardware store and got a new one (1.25" by 1.25"). The problem is that the distance shown in the picture is too short, so that when I put the new one on the bottom part is about 3/4" below where it needs to be. How do I specify this dimension when ordering a new one, as I didn't see it listed anywhere. Thanks.

    You need to cut the piece that slides over. They dont make traps with what your showing at different dimensions.

    Thanks, CT18. I guess they used to make them with different dimensions, because the old one fit better.

    So how would you cut this pipe? Dremmel? Pipe cutter?

    ?
    Not sure I follow this.
    What piece is to be cut? The tail piece, that fits inside the trap?
    Or is the top of that new trap too low and he needs a longer tail piece?

    EDIT: Or did you mean to say, "You need to cut the piece that it slides over.

    A hack saw with a bi-metal blade will cut it
    the correct way would be with a pipe cutter like a rigid #20

    They require extension pieces that you cut to fit with a pipe cutter or hacksaw.
