Dishwasher in tricky location


I am installing a dishwasher in my kitchen. Because of the layout of the kitchen it can not be near the sink. It is 12' away.

I can not run a vent up inside the wall it will be on the center wall of a 1973 modular house. It is built in such a way that it is impossible to run a 1.5" pipe up it.
I will have a 12" cabinet beside the dishwasher, unfortunately there is a heating duct directly below it and I can not go down through the floor joists and into the basement here.
The floor joists under the dishwasher are open.

Here is my question. Can I run the 3/4" line with a high loop behind the dishwasher, through the floor and into a 1&1/2" line with a P-trap then over the 8' to the main stack.

The 3" main stack is 8' away.

I have attached a drawing of my idea.


(Sorry for the large size, I can not get it resized smaller)


Hope this helps.

Thanks

I realize with a bit more work I could run a re-vent.
Tie in a 1&1/2" line in the wall beside the 3" main stack. run that down and under the floor over to the dishwasher, tie in the 3/4" high loop line, then a p-trap, then into the main 3" stack.

Not sure which side of the P-trap the re-vent should tie in on, re-vent high loop P-trap or high loop p-trap re-vent (I think the second is right)

Here is a pic.

Im totally not a plumber and asking questions just like you.

However, fwig, that reventing is right and required. But it cant revent any lower than other fixtures drains (hey, doesnt your sink/vanity have a revent too?)

There's some allowance for wet venting in some codes now (Ontario Canada for eg) but only under very specific circumstances. i think it does not apply to you here (nor me in a similar situation).

Twelve feet is a long way to transport quick rinsed dirty dishes from the sink to the dishwasher. Dirty water and food particles can drip on the floor unless you use a deep tray to load the dirty dishes in for transport. The tray will be heavy and probably require multiple trips. I think that can get pretty old pretty quickly. Have you considered the human aspect of your plan?

I agree with Homerepairguy, no sensible kitchen design would have the dishwasher 12' from the sink. Whoever does the dishes will come after you with a frying pan.
