What are the criteria for inspecting grease traps?
Grease trap and grease interceptor inspections follow the same standard guidelines. The inspector will check that the system is functioning properly. The depth of the sediment and grease layers will be checked. If the combined grease and sediment layers equal or exceed 25% of the trap or interceptor capacity, the device will need to be cleaned. The inspector may also ask to see the maintenance and cleaning records for the trap or interceptor.
