4 The defi nition of Plumbing fi xture has been modifi ed to include fi xtures such as waterless code : Plumbing Fixture. A receptacle or device that is either permanently or temporarily connected to the a water distribution supply system or of the premises and demands a supply of water therefrom; discharges wastewater, liquid-borne waste materials or sewage either directly or indirectly to a the drainage system of the premises; or requires both. Such receptacles or devices require a water supply of water; connection and a or discharge liquid waste or liquid-borne solid waste; or require a supply of water and discharge waste to a the drainage system of the SIGNIFICANCE: The previous defi nition of Plumbing fi xture was outdated and incomplete. The defi nition now includes receptacles and devices that do not necessarily require connection to a water supply.

Any one of a special class of Plumbing fi xtures Water-connected or drain-connected devices intended to perform a special function. Included are fi xtures having the These devices have their operation or control dependent on one or more energized components, such as motors, controls, or heating elements or pressure or temperature sensing elements.

6 Such fi xtures devices are manually adjusted or controlled by the owner or operator, or are operated automatically through one or more of the following actions; a time cycle, a temperature range, a pressure range, a measured volume or SIGNIFICANCE: The modifi ed defi nition of Plumbing appliance provides a better distinction between appliances and fi xtures. The revised text updates and simplifi es the defi nition, now recognizing these two classes as different. Examples of Plumbing appliances include dishwashers, clothes washers, garbage disposals, water softeners, water purifi ers, and water garbage disposalInternational code Council 56/29/11 12:54 PM6/29/11 12:54 PM6 PART 1 International Plumbing Code202 Grease Interceptor Defi nitionCHANGE TYPE: Modifi cationCHANGE SUMMARY: The defi nition of grease interceptor has been modifi ed for consistency with current industry terms for the two general types of grease interceptors being used in Plumbing code : Grease Interceptor.

8 The new terminology now makes a clear distinction between the two types of grease interceptors, hydromechanical and gravity. The revision to the defi nition along with the changes made in Section place the IPC in better alignment with product standards and industry terminology. Both types of grease interceptors require diligent effort by restaurant facility managers and staff to ensure that they are regularly maintained and properly serviced. For a grease collection device to work correctly, it must be properly designed, installed, maintained, and serviced 76/29/11 12:54 PM6/29/11 12:54 PM8 PART 1 International Plumbing , Identifi cation and Third-Party Certifi cationCHANGE TYPE: Clarifi cationCHANGE SUMMARY: The identifi cation requirements for Plumbing products and materials have been clarifi code : Identifi cation.
