Dishwasher with no Garbage Disposal

[micalk]

How's it done? The instructions have the dw drain going straight into the plumbing, no air gap. Can it be run similar to a clothes washer drain, where the output of the dw is hooked over the edge of a drain pipe angled out of the wall with a P-trap at the bottom? What are my options? This is a Fischer-Paykel single drawer and will be used mainly for cups and silverware at the coffee bar, so I'm not concerned about any heavy waste, though my main dw is a little far from the kitchen sink, and may employ a similar technique there, if practical.

Air gaps are not always required by local codes. If one is not used, then the drain hose must be looped and attached under the counter top. It attaches to the sink drain with a special tail piece that has a pipe stub teed out of it that the hose clamps onto. If an air gap is required or desired, then it is install in the counter top. The hose attaches to the drain the same as described above.

Dishwasher Branch Tailpiece. Search for that. Add "tubular" as one more keyword if necessary.

As Gary said, an airgap may not be required. Check with the local plumbing authority in your jurisdiction. If you don't use one, just be sure to loop the drain hose and attach it to the underside of the counter.

Good luck

Thanks, RioHyde - That's exactly what I was looking for. AFAIK, I'll need an airgap too, but that's between me and my inspector....
