Air Gap Question

Greetings to all!

I have a new restaurant going in to an existing tenant space and they have

installed a new 3 compartment sink (along with the other restaurant stuff).

The plumber-of-record has installed pvc drain lines from each drain outlet,

in each sink compartment and in to an above grade grease interceptor and

then in to a floor sink (i.e. - direct connection of the sink drain lines in to

the grease interceptor). I am challenging this type of type of connection.

It is my belief that the 3 comp. sink should have an air gap type of connection

before going in to the above grade grease interceptor.

What say ye? Please cite, either for or against, this type of drain connection.

We are using the 2006 Edition of the IPC.

Thanks ya`ll!

Check with the health department. We went through this about a year ago. The UPC allowed a direct connection and the health department rules did not. We now tell the plumbers they need the air gap to get approval from the health department. Consistency in enforcement is a good thing no matter who has the most restrictive rules/codes
 
Thanks "pwood" & "mtlogcabin" for the input! I agree that that an air gap

probably should be required, but the IPC Commentary did not even require it,

because of "the already dirty environment" in which is present in the 3 comp.

sink.

Not sure of what the Health Dept. here is going to say about the connection,

if they even notice it. :eek:
