Grease interceptor connection question
Grease interceptor connection question
(OP)
Dear Members,
Model plumbing codes require indirect piping (air gap) when connecting food handling fixtures to the plumbing system. Typical arrangement for restaurants is: triple sink - grease trap - plumbing system. My question is - where it is preferable to put an air gap - upstream or downstream of grease trap. I saw recommendations to do it immediately after sink (which means upstream), but I doubt if it is going to work, because typical grease trap has flow control fitting upstream. Is it regulated by code?
Any suggestions?
Thank you very much in advance!

Thank you very much for the response. I am in New York City, so the plumbing code is a little different and does not have illustrations. I saw the Illinois code but I believe that it does not describe this specific situation. As we know, codes are sometimes unclear.
BTW, if it looks like I violate somehow the rules of the forum (if so, it is really unintentionally), I will stop this thread immediately. Thank you very much again for your help.

I have on one my drains from the kitchen sink just to prevent any grease going into my septic system.

The other thing with these items, is to watch the material they are made from. Corrosion and rust through is very common on these, after they are put in service.
