All exterior interceptors shall be designed and constructed in accordance with this paragraph, so as to constitute an individual structure. The code does allow the interceptor to serve as a trap (assuming that this interceptor is intended to serve as a fixture trap) thus adding a trap to the fixture upstream of the interceptor creates a double trapped fixture installation. Section 890.510 - Grease Interceptor Requirements. Since the interceptor comes with a flow control in the inlet, if your drainage flow rate exceeds the rating of the interceptor the waste will back up and end up on the floor.

Most inspectors would say yes because the unit itself is trapped and a trap needs a vent, but if you ask the inspectors in Los Angeles City, they would say no, due to the fact that each fixture upstream of the trap is individually vented. Proper maintenance is the key to meeting these limits. PDI G101 and ASME A112.14.3 Type A certified interceptors are required to have a vented external flow control installed upstream of the interceptor. (a) in no case be less than 1 in. Again, there is nothing wrong with this installation, though it may not be immediately obvious as to why.

If you are designing in the UPC, there is a table in the Code for sizing the interceptors based on pipe size and associated peak flow rate, and then assigns interceptor sizes based on one-minute and two-minute drain down times. To separate them from water an interceptor provides a separation chamber which allows FOG to rise to the surface.
