My dishwasher is 20 years old and needs to be replaced and does NOT have an air gap.
My association maintenance 'guy' says that I need to install an air gap before he will install a new dish washer.
I am in Southern California, (Orange County).
It seems that if it worked for 20 years WITHOUT an air gap, then the high loop that is installed is working.
(I don't have a knockout free into which I might install an air gap)
Ideas???

the place where you buy it should have an installer, (in some cases they even do it for free).

if it is a code requirement then you have to do it.
if it is not then get someone else to do it.

Even IF it were a code requirement, it is something that is "ignored" more often than it is followed.

aparently the OP is part of a condo association. most that i am familiar with want the code followed not ignored. if people start ignoriong all codes then it hurts everyones property value and that is why the associations are formed.

California Plumbing Code has required an air gap for a long time. Have an air gap installed with the new DW.

Codes requiring air gaps are put in place to protect YOU. It eliminates the possibility of sewage being drawn into YOUR dishwasher. Now...Why would YOU not want it?

paul, the dishwasher air gap regulation puzzles me. as restrictive as our plumbing codes are in MA, we are only required to use a high loop in the dishwasher drain. as far as i know, no one has died from the bubonic plague.

I assumed it was in place to eliminate the possibility of water siphoning back to the dishwasher and flooding out and causing property damage.

In the olden days, in a land far far ago:
The 'high loop' was required to be 1" minimum above the flood level of the sink.
There were actual counter mounted loops for this purpose (not air gaps, merely 'decorative' return bends).
or
A loop of copper tube inserted into and up a slot in the wall behind the cabinet for a hidden appearance.
(said loop would be permanent and used for future DWs)
While this may not prevent actual siphonage from the DW, it will prevent backflow from an overflowing sink (whether due to water overfill or stoppage).
As 'high as you can' inside the cabinet is a modern cheat (albeit legal in some jurisdictions).
There ..... showing my age and training ..... again.
