True or False: A grease interceptor's inlet and outlet connections follow the same vent-distance principles as any other trapped fixture connection.
Not quite. The answer is A: True
An interceptor's larger size doesn't exempt it from ordinary trap-seal physics — its inlet and outlet are still vulnerable to siphoning if run an excessive distance without a vent, so the same distance-based venting logic that applies to a sink trap applies here too.
Reference: UPC 2021 §1014.1.1 (Fixtures discharging to an interceptor must be trapped and vented)
