I am in the process of installing a dishwasher in my home. Because of the layout of the kitchen it will be 12 feet away from the sink on another wall. I can not run a vent line up inside this wall as it is the centre wall in an 1973 modular house.
Also because of a heat duct in the floor joists I can not run a 1 1/2" drain line in the 12" cabinet beside the dishwasher.
1. The main 3inch stack is 8feet away. Can I run the discharge hose with a high loop behind the dishwasher below my floor joists on the basement ceiling and wye straight into the main stack? This would come in below all the other plumbing fixtures (sink, lavatory, toilet, tub.)
2. What size of line - 3/4" or go to something larger?
3. Would I need a P-trap in this line. as the high loop keeps water in the pump which acts like a p-trap.
I have used loop vents and re-vents in the past and because of obstructions and layout these are not possible. I had also thought of an AAV vent in the 12" cabinet beside the dishwasher but because of the heat duct in the joist space directly below it that is not possible.
Thanks for any help.
