SPS 382.41(3)(b)4.b. b. A water supply faucet, wall hydrant or other outlet which terminates with a serrated nipple allowing a hose to be attached;
SPS 382.41(3)(b)4.c. c. A water supply faucet, hydrant or outlet serving a sink used for building maintenance in a public building;
SPS 382.41(3)(b)4.d. d. A chemical pot-feeder or automatic chemical feeder is installed to serve a boiler, cooling tower or chilled water system; and
SPS 382.41(3)(b)4.e. e. In the water supply piping connecting to the outlet of a fire hydrant for any purpose other than fire suppression.
SPS 382.41(3)(b)5. 5. A cross connection shall not be considered to exist at the hose threaded outlet installed for the sole purpose of:
SPS 382.41(3)(b)5.a. a. Draining a water supply system or any portion thereof;
SPS 382.41(3)(b)5.b. b. Obtaining water quality samples of the water supply system or any portion thereof; or
SPS 382.41(3)(b)5.c. c. Connecting individual residential automatic clothes washers.
SPS 382.41(3)(b)6.a.a. A high hazard situation shall be considered to exist for the connection of 2 water supply systems one supplied by a public water supply and the other system supplied by a private well.
SPS 382.41 Note Note: The interconnection of a public water supply system and another source of water is addressed in s. NR 811.09 and must be approved by the Department of Natural Resources.
SPS 382.41(3)(b)6.b. b. Except as provided in subd. 7., a low hazard situation shall be considered to exist for the connection of a piping system, including but not limited to automatic fire sprinkler systems, standpipe systems, and processing purposes, which provides potable water for nonrequired potable water uses.
SPS 382.41 Note Note: Cross connection control devices used in conjunction with automatic fire sprinkler systems are to be listed by an acceptable testing agency for such an application under the standards governing the design and installation of automatic fire sprinkler systems.
SPS 382.41(3)(b)7. 7. A cross connection situation shall not be considered to exist when a multipurpose piping system serves a one- or 2- family dwelling provided the sprinkler system is constructed of materials and joints suitable for water distribution systems as specified in ss. SPS 384.30 (4) (e) and 384.40, respectively.
