Washing Machine Drain Under Kitchen Sink
I'm about to test this setup by running the washing machine. Who thinks this won't work and why? What you are looking at is 9 feet of 3/4" SCH40 PVC from the washing machine drain to the 1 1/2" PVC tee and then through the p-trap and out to the main drain line.
I don't like to violate code but sometimes it's the only reasonable option.
