    Hi all - for some reason every example out there has the sink "downstream" of the WM standpipe.
    If you would, please let me know if there's anything amiss with this schematic - using UPC:

    Add a cleanout for the end of run and you're good.
    Kitchen sink also gets a cleanout.

    "1.5" in the lower right and the "2" above, are not compatible. Probable typo.

    Lower right needs to be a long sweep.

    Double-checking - am I ok with a 2" san-tee for the WM drain, into a 3" bushing at the floor - or do I need to carry the 3" up?
    Trying to keep the washer drain as low as possible.

    Not sure how to read the DFU sizing - is it max 10 dfu for a 2" vertical drain (aka stack <3 stories)?
    Do the kitchen sink and dishwasher count as 4 dfu?

    EDIT: found it

    Thanks,
