Hi,
I am re-plumbing a dishwasher and have a problem with leakage from the airgap. It seems the DW outlet water pressure is quite high and water spews out through the airgap. It does partially flow through the 7/8 outlet to the disposal unit as well, but about 50% flows out through the airgap.
I have punched out the knockout on the disposal unit inlet and have also tried lenghtening the DW outlet tube to about 8ft with multiple loops to no avail.
Any ideas would be appreciated.

Rather than connecting your dishwasher outflow directly to the drain, some codes require the flow to be connected to an "airgap" mounted on top of the sink counter top. The idea is that it prevents waste water siphoning back into the dishwasher. That's all very well, but as you can tell from my question, it isn't functioning as it should!

The drain hose from the airgap to the disposer needs to go down hill with no sags or kinks in the hose. If you have those, food will collect in the hose, and create a blockage. Take the hose off the disposer, clean it out, hook it up the correct way and you should be good to go.

If your code allows, eliminate the air gap apparatus and run the drain line so a loop goes right up under the countertop. Use a nylon tie or wire to hold it up. Then hook it up to your disposal in the regular way.

It sounds like the 7/8" hose is clogged, bent or collapsed causing the problems you are having.
Inspect the Air Gap for obstruction.

Air gaps are required in California. Disconnect the hose from the disposer, point it at a bucket and see if the water still comes out the air gap. I also feel there is a restriction in the hose or air gap outlet nipple.

Problem solved! I actually did check the disposer hose for kinks and blockages and found none, which is why I was so confused. The problem turned out to be the air gap apparatus itselt. The air outlet or hole piece on the top was actually inserted incorrectly. Re-adjusting this solved the problem!
Thanks for all the help. This is a great site.
