I'd like to drain the overflow from an aquarium (self filling) to the
waste water pipe in the basement. The most convenient place to access the
pipe is the dishwasher connection from upstairs. There is a Wye in the
main drain line, with a reducer and a threaded barb, which attaches to the
DW upstairs. I was thinking I could put a Tee on this reducer and use that
to hook up my aquarium.

I see several problems here, including possible backup of the dishwasher
drain into the aquarium (dead fish) or back up sewer gas into the aquarium
(dead fish). So what's the right way to do this?



I would run the excess water to the garden....it should be good for the
plants.....Ross
