Performance Requirements for Plumbing Aspects of Residential Food Waste Disposer Units
ANSI Approved: September 2020
This standard applies to the plumbing aspects of residential food waste disposers intended primarily for installation in the residential kitchen sink outlet. When supplied with water from the sink supply faucet, these devices discharge into the sanitary drainage system.
These devices shall be designed to reduce food waste particle sizes for discharging into the sanitary drainage system. Devices shall include a means of self-cleaning and means to protect against mechanical shock. When a dishwasher discharge connection(s) is incorporated in the device, the device shall be designed so that if the discharge connection becomes blocked, backflow into the dishwasher shall not occur.
