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.b.
b. Obtaining water quality samples of the water supply system or any portion thereof; or
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.
SPS 382.41(3)(c)1.1. For sewerage treatment facilities which are required to conform with
ch. NR 110, in addition to the cross connection control required for each potable water usage or water outlet, a reduced pressure principle backflow preventer shall be installed:
SPS 382.41(3)(c)1.b.
b. In the private water main upstream of all water services serving the facility; or
SPS 382.41(3)(c)1.c.
c. In the water distribution system upstream of all water outlets and in the process piping network upstream of all points of use, if both a water distribution system and a process network is contained within the same building or structure.
SPS 382.41(3)(c)2.
2. For marinas, wharves and docks where potable water outlets are provided to serve boats or ships, in addition to the cross connection control required for each potable water outlet or usage, a reduced pressure principle backflow preventer shall be installed in the water supply system to limit backflow into the water supply source.
SPS 382.41(3)(c)3.
3. The installation of a cross connection control device in the water supply system for a building or structure shall not alleviate the requirement to provide cross connection control for the connection of each plumbing fixture, piece of equipment, appliance or other piping system.
SPS 382.41(3)(d)
