Threaded faucets and threaded drain valves may not be installed in place of a smooth end sample faucet even if the threads have been filed off. Petcocks may not be used as sample faucets. Any faucet used for recirculation shall be installed with a hose connection vacuum breaker.

NR 812.34(1)(c)1.1. When a buried pressure tank, a pitless receiver tank or an above ground discharge unit is installed, the sampling faucet shall be installed immediately following the point of entry into the building or building basement.

NR 812.34(1)(c)2.2. When an approved above ground discharge unit is used and the pressure tank is in the basement, the sampling faucet shall be installed in the service pipe from the tank at least 12 inches above the floor. The sampling faucet may be placed in the pump discharge line if there is no loss of air from the system when the faucet is opened.

NR 812.34(2)(2) An entry point sample faucet shall also be installed for a non-community water system after treatment or chemical addition, if any, but prior to the distribution system for sample collection and compliance with the monitoring requirements of ch.

All backflow prevention devices shall comply with ch. SPS 384 and shall be installed and maintained in accordance with ch. SPS 382.

NR 812.35(1)(b)(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.

NR 812.35(2)(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.

NR 812.35 NoteNote: 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.
