Wis. Admin. Code NR § 812.35

Current through May 28, 2024

Section NR 812.35 - Yard hydrants

Yard hydrants may be installed in a water system provided they are not installed in or on a well and have been approved by the department of safety and professional services for this purpose. All backflow prevention devices shall comply with ch. SPS 384 and shall be installed and maintained in accordance with ch. SPS 382.

(1) Yard hydrants having hose threaded outlets shall either:

(a) Have a hose connection vacuum breaker installed on the hose threads.

(b) Have a reduced pressure principle backflow preventer or a backflow preventer with intermediate atmospheric vent installed in the water supply pipe which serves only the yard hydrant or hydrants.

(2) Yard hydrants without hose threaded outlets may be installed without additional backflow protection if the outlet of the yard hydrants complies with the air gap requirements in s. SPS 382.41.

Note: Chapter SPS 384 requires that backflow prevention devices such as hose connection vacuum breakers, backflow preventers with intermediate atmospheric vent and reduced pressure principle backflow preventers must be reviewed by and receive device approval from department of safety and professional services. Chapter SPS 382 requirements do not allow backflow preventers to be buried or installed in a pit. Installation of hose connection vacuum breakers in areas subject to freezing must be of the type that allows draining. Department of safety and professional services plan approval must be received prior to the installation of a reduced pressure principle backflow preventer. Reduced pressure principle backflow preventers must be installed by a plumber licensed under ch. 145, Stats. and listed by department of safety and professional services to do such work. The device must be tested at least once a year by a department of safety and professional services listed backflow prevention device tester.
