    Hi all - working on a basement bathroom and am to the point of running my drain from the lav.

    I currently have it laid out with two long sweep 90s (top down view of the rough sketch attached). I recall something about 135° max turn on horizontal line but can't find any definite answer where that came from. If I end up having to use a 45 instead of the second long sweep, how far do I offset from center of the sink to tie into the p-trap.

    As always appreciate everyone's advice.

    That part of the code doesn't pertain to what your doing. As long as you use long sweeps youll be OK.
