Nev. Admin. Code § 446.435 - Drains

Current through March 28, 2022

1. A direct connection must not exist between the sewage system and a drain originating from equipment in which food, portable equipment or utensils are placed, except where floor drains located in refrigerated spaces are constructed as an integral part of the applicable building.
2. If a dishwashing machine is located within 5 feet (1.52 meters) of a floor drain with a trap, the waste outlet for the dishwasher may be connected directly to the drain on the side containing the inlet if the trap is properly vented.
3. Every drain, overflow or relief vent from the water supply system must have an indirect connection to the waste system. Drain lines from equipment must not discharge wastewater in a manner that floods any floor or causes water to flow across any work area or area which is difficult to clean.
4. All indirect waste piping must discharge into the drainage system of the applicable building through an airgap or airbreak. Where a drainage airgap is required by the health authority, the minimum vertical distance as measured from the lowest point of the indirect waste pipe or the fixture outlet to the flood-level rim of the receptor must not be less than 1 inch (25.4 mm).
5. A floor drain must be provided in any area where meat, fish or poultry is processed.
6. As used in this section:
(a) "Airbreak" means a physical separation, including, without limitation, a low inlet into an indirect waste receptor from a fixture, appliance or other device indirectly connected thereto.
(b) "Drainage airgap" means the unobstructed vertical distance through the free atmosphere between:
(1) The lowest opening from a pipe, plumbing fixture, appliance or appurtenance conveying waste to a receptor; and
(2) The flood-level rim of the receptor.
