I am not a fan of CD’s Jeff, call me old school but I like my code books to be books. I bought the spiral bound book with tabs.
Joe, Larry is correct the picture is wrong. Here as long as the hose loops up near the flood rim it is ok as Jeff said.
Don’t forget, an air-gap is also an anti-bacterial device, which a high loop cannot provide. At least that’s what I think, but have no scientific data to back that up.
Perhaps. Wouldn’t dishwasher waste water still be in the upflow drain line to the air gap, or the high loop in either case? Even if it’s from the final rinse, that tube isn’t too pretty after a couple years of use…yuck.
I think Keith is referring to water/waste going the other direction - from the disposal to the DW. This creates some pretty nasty conditions and a horrible odor over time.
I went by what the local inspectors said. they had the final say.
Either they follow and enforce the UPC, or they don’t. Apparently, in your case, they don’t.
Here, Jeff, they follow Charlotte County, which ain’t California, ICC, IBC, UPC, UBS or anything else. It seems that pretty much, for better or worse, it depends upon which inspector checks what on any given day, and what the inspector feels like.
Local jurisdictions often permit a high loop and consider it equivalent to a backflow device. I’ve found it risky in terms of irritating clients to make a very specific call. I agree with noting the condition and suggest consulting a qualified plumber or the local building department for a specific local interpretation.
We’ve got areas in CA that like to make their own “calls” as well. In any event, a high-loop and an airgap fitting are not the same.
The IRC, in this case, contradicts itself with regards to the requirements and definition of “indirect waste” discharge, while the UPC stands firm.
IRC P2706.3 Prohibited waste receptors. Plumbing fixtures that are used for domestic or culinary purposes shall not be used to receive the discharge of an indirect waste.
Exceptions:
- A kitchen sink trap is acceptable for use as a receptor for a dishwasher.
P2717.2 Sink and dishwasher. The dishwasher waste line shall rise and be securely fastened to the underside of the counter before connecting to the sink tailpiece.
Commentary: Dishwashing machines may connect directly to the drainage system and do not require an indirect connection by drainage air gap or air break.
As far as I’m concerned, the Pope is God’s annointed deputy on earth, and that’s it. Pope wins.
At least Jeffrey Pope I can understand.

Nuther stupid question (I ain’t no plumber). The air admittance valve is not an air gap. Right??? The air gap is the little thingy that sits on top of the sink? Correct?
An AAV is simply a “vent” system, different from an airgap fitting or device.
The airgap FITTING is that little “thingy” on top of the sink. The air gap is. . . well. . . an air gap - the space (air) between (gap) the discharge pipe and a receptor.
Joe,
I see you are a NACHI Member, but your questions here are so elementry that I wonder - did you complete a comprehensive training course as preparation to become a Home Inspector? If so, can we have the name of the provider of the course so as we can advise that it may be a poor value as a training course? Please don’t be offended - we (well most of us) have gaps in our training. And, Joe, if I am out of line here you can be sure that many of our NACHI member will jump all over me - I am curious myself as to when we want to learn more for the benefit of the whole?
Great article Michael. Thanks. That clears it up.
