(A) Water supply.
(1) Potable water from an approved source shall be available at all times in residential buildings. The domestic water supply system of the building shall be connected to such approved source and shall not be subject to contamination. When supplied from a public source, the potable water supply system shall not be connected to private or unsafe water supplies.
(2) Water supply systems shall be installed and maintained so as to provide at all times a supply of water to plumbing fixtures, devices and appurtenances in sufficient volume and at pressures adequate to enable them to function satisfactorily and without undue noise under all normal conditions of use.
(3) Water supply systems shall be installed and maintained so that water used for purposes of cooling or heating shall not be reintroduced into the domestic water supply system nor be distributed through such equipment to plumbing fixtures.
(4) Hot water supply systems shall be provided with safety devices arranged to relieve hazardous pressures and excessive temperatures.
(B) Cross-connection.
(1) The city adopts by reference the Water Supply Cross-Connection Rules of the state’s Department of Environmental Quality being Mich. Admin. Code R. §§ 325.11401 to R 325.11407.
(2) It shall be the duty of the city’s Water Department to cause inspections to be made of all properties served by the public water supply where cross-connections with the public water supply is deemed possible. The frequency of inspections and reinspections based on potential health hazards involved shall be as established by the city’s Water Department and as approved by the state’s Department of Environmental Quality.
(3) The representative of the city’s Water Department shall have the right to enter at any reasonable time any property served by a connection to the public water supply system of the city for the purpose of inspecting the piping system or systems thereof for cross-connections. On request, the owner, lessees or occupants of any property so served shall furnish to the inspection agency any pertinent information regarding the piping system or systems on such property. The refusal of such information or refusal of access, when requested, shall be deemed evidence of the presence of cross- connection.
(4) The city’s Water Department is hereby authorized and directed to discontinue water service after reasonable notice to any property wherein any connection in violation of this section exists and to take such other precautionary measures deemed necessary to eliminate any danger of contamination of the public water supply system. Water service to such property shall not be restored until the cross-connection(s) has been eliminated in compliance with the provisions of this section.
(5) All testable backflow prevention devices shall be tested initially upon installation to be sure that the device is working properly. Subsequent testing of devices shall be conducted at a time interval specified by the city’s Water Department and in accordance with State Department of Environmental Quality requirements. Only individuals approved by the city’s Water Department shall be qualified to perform such testing. The individual(s) shall certify the results of his or her testing.
(6) The potable water supply made available on the properties served by the public water supply shall be protected from possible contamination as specified by this section and by the State and the City Plumbing Code. Any water outlet which could be used for potable or domestic purposes and which is not supplied by the potable system must be labeled in a conspicuous manner as: “WATER UNSAFE FOR DRINKING”.
(7) This section does not supersede the state’s Plumbing Code and the city’s Plumbing Ordinance, but is supplementary to them.
