How to plumb in a dishwasher

There is a little rubber "Y" thing that goes under the kitchen sink drain. Since the dishwasher pumps, water flows uphill. You also nned to "T" off the hot water line and provide a separate shutoff (one for the sink and another for the dishwasher).

Then there is the electric service.

There is more to it than that. If you have a garbage disposal, it is best to run the dishwasher drain to the fitting on it. You also need to prevent the sink drain from ever backing up into the dishwasher. Usually a ''high loop'' running the drain hose up to the underside of the counter works, but your local code may require a special valve. Since the plumbers here disagree on that issue, I will only point out that it exists and suggest checking to see what they say later.

If you use the disposal as a drain be sure to remove the knock out plug inside the disposal inlet.
