Grease interceptor Q.

[SCBO1]

Is it code that the bathroom sanitary sewer connect to the Grease Interceptor or can it by-pass the GI and re-connect to the SS line after the GI before entering the City sewer main?

Any code section to reference?

It is a grease interceptor not a septic tank. The sanitary sewer does not connect to the grease interceptor

1003.3.1 Grease interceptors and automatic grease removal devices required.
A grease interceptor or automatic grease removal device shall be required to receive the drainage from fixtures and equipment with grease-laden waste located in food preparation areas, such as in restaurants, hotel kitchens, hospitals, school kitchens, bars, factory cafeterias and clubs. Fixtures and equipment shall include pot sinks, prerinse sinks; soup kettles or similar devices; wok stations; floor drains or sinks into which kettles are drained; automatic hood wash units and dishwashers without prerinse sinks. Grease interceptors and automatic grease removal devices shall receive waste only from fixtures and equipment that allow fats, oils or grease to be discharged. Where lack of space or other constraints prevent the installation or replacement of a grease interceptor, one or more grease interceptors shall be permitted to be installed on or above the floor and upstream of an existing grease interceptor.

Going with MT...The AHJ for sewer or septic should be the one to say what goes where...Never seen a WC go to grease...

"Grease interceptors and automatic grease removal devices shall receive waste only from fixtures and equipment that allow fats, oils or grease to be discharged."

That's the key phrase........

Thanks for the feed back,

Best comment I heard so far is; "It's not a septic tank!"
