I need to install a dishwasher at my nephew's new (old) house. It needs to be placed NOT ADJACENT to sink. (Two cabinet bays away).
I'm thinking that I should erect a standpipe drain behind the dishwasher, with a trap below floor level in the basement. Then have the discharge hose go into the top of the open pipe the way a clothes washer's does. Standpipe needs to fit behind washer, in front of wall.
Question: What is minimum size for standpipe to be used in this situation?
Or should I be approaching this in some other way?
Thank you.
