Rule 3701-28-08 | Pumps, pressure tanks, and other requirements for all private water systems.
(A) If the department or board of health determines that any private water system, any part thereof, or any appurtenance thereto, is being maintained in such a fashion, has deteriorated to such an extent, has been abandoned, that a safety hazard exists or contaminants might enter ground water or the potable water supply so as to constitute a public health hazard, the department or board of health shall order such work to be performed on the private water system as is deemed necessary to prevent contamination of the ground water or the supply to protect public health or safety. If there is known groundwater contamination in an area, the board of health or the department may require access be provided for sampling of a private water system in that area for such parameters as are necessary to determine if the private water system is impacted by or contributing to the contamination, and may order such work as is necessary to ensure that the existing private water system does not contribute to the transport of the contamination.
(B) All pipe and fittings utilized in the water piping system of a private water system outside and inside of a house or building, shall be of materials conforming to table 1 and 2 of this rule. All pipe and fittings utilized in private water systems shall also conform to NSF 61-2016.
(C) All pipes and valves shall also be protected from freezing or other physical damage. Valves shall be installed so that they are accessible from the surface of the ground by means of an open stack.
(D) All pipe fittings and nipples shall be approved for installation with the pipe material and shall conform to the respective pipe standards or one of the standards listed in table 605.5 or table 605.8 of rule 4101:3-6-01 of the Administrative Code.
