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:
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?
