dishwasher air gap Huntington Beach California

afiore · Feb 28, 2007, 12:38 PM

Is the installation of a dish washer air gap above the counter a code requirement in Huntington Beach California? I would like to eliminate as many above counter items as possible in my new kitchen installation with granite countertops and undermount stainless steel double sink.
Can the dishwasher discharge hose be air-gapped directly into the sewage vent pipe? Currently the kitchen walls are open and such an installation can be made.
Thanks for your help.

is there an odor that comes out of that airgap? does that airgap contaminate any food placed near it?

Here are some pics of a recent installation, the craftsmanship is somewhat dubious, and the installer has been chastised.

The part you see going through the plywood is the air-gap, and has a round, perforated trim piece that is open to the atmosphere.

As for the standpipe backing up, this has never been an issue in all the time I've used them, bear in mind that the 1/2 copper tube is similar in diameter to the dishwashers drain hose, which is 5/8 I.D.

Thanks for the pics and he explanation about the air gap being exposed to the out side air. I have never seen an air gap installed in this manner and wish I had because of the many times that I had to either drill a cast iron sink or bring the air gap up through the counter top and if it ever stop up then it was all over the counter,,,,,thanks again.
