Oil lubricated lineshaft turbine pumps may be used for potable wells when the pumping water level is deeper than 250 feet except when the pump operation is expected to lower the water level in the well to a depth less than 5 feet above the bottom of the well casing pipe. Oil lubricated lineshaft turbine pumps may be used for wells provided the lubricants are USDA or FDA approved food contact grade formulations.
NR 812.32 Note Note: Such formulations are usually based on National Formulary white, food grade mineral oil.
NR 812.32 Note Note: The department may allow the installation of oil lubricated lineshaft turbine pumps for potable wells when the pumping water level is less than 250 feet deep when unique circumstances warrant such installation.
NR 812.32(6) (6)Discharge lines from lineshaft turbine pumps.
NR 812.32(6)(a)(a) Pressurized. Discharge lines from lineshaft turbine pumps that are maintained under system pressure at all times shall contain an air-vacuum relief valve preceding a check valve. A well vent shall be installed in the pump base. High capacity well pump installation is depicted in Figure 3 of ch. NR 812 Appendix.

NR 812.32(6)(b) (b) Nonpressurized. Discharge lines from lineshaft turbine pumps shall contain an UL approved check valve and an air-vacuum relief valve near the pump, and prior to any buried portion of discharge pipe.

NR 812.32(7) (7)Hand pumps.
NR 812.32(7)(a) (a) Hand pump heads shall be designed and fabricated so there are no unprotected openings, other than the spout, to the interior of the pump. The water spout shall turn downward and be closed on top. If a separate watertight port is provided for priming, it shall be sealed watertight when not being used. Unsealed openings may not exist in the pumpbase. If the pump is installed outside, a concrete crack-free watertight pump platform at least 6 feet in diameter shall be provided. The top of this platform may be at ground grade, but in any case the platform shall be mounded so that water does not accumulate around the well. If excess water flow from the pump spout is channelized, it shall be directed to a point at least 8 feet from the well with a drain pipe or watertight channel.
NR 812.32(7)(b) (b) Hand pumps shall be connected firmly to the well casing pipe by threading in small diameter well casing pipe or by bolting the pumpbase flange to a well casing pipe flange with a gasket to seal the top of the casing. Other types of hand pump bases may be used if they meet the approval requirements specified in s. NR 812.091 for vermin-proof caps and seals.
NR 812.32(8) (8)Casing not part of pump installation. The well casing pipe for any drilled well greater than 2 inches in diameter may not be used as a delivery pipe in the pumping operation, except when the well casing pipe is under continuous pressure as with a packer-jet pump installation.

NR 812.32(9)(a)(a) Underground pipe connections. Underground pipe connections may only be made to a flowing well with an approved pitless adapter.
NR 812.32(9)(b) (b) Unprotected suction lines. An off-set shallow well pump may not be connected directly to the buried pipe exiting a pitless adapter or unit of a flowing well or to a pipe extending out of the seal at the top of the well and redirected back into the ground. Buried piping from the flowing well shall discharge to a surge tank having either an overflow pipe or an air-vacuum relief valve installed in the top of the tank. A booster pump shall be connected to the surge tank and discharge into a pressure tank.
NR 812.32(9)(c) (c) Overflow piping.
NR 812.32(9)(c)1.1. When a flowing well is placed in use, the flow from the well shall be regulated by means of a control valve with a screened outlet or with a restricting orifice to prevent waste of water. The control valve shall be restricted as much as possible and closed if the flow ceases.
NR 812.32(9)(c)2. 2. A controlled overflow pipe or other means shall be installed for a flowing well to prevent damage from overflowing water or to prevent freezing of the top of the well.
NR 812.32(9)(c)3. 3. When necessary, overflow piping shall be installed to prevent flow of water up the outside of the well casing pipe or to prevent freezing of water inside the casing. When installed, the flow of water from the discharge pipe shall be limited to a minimum so as to preserve groundwater and water pressure. The overflow pipe shall be installed to extend through the well cap or seal or shall extend off a surge tank in the basement. The overflow pipe may be attached to the outside wall of the well casing pipe if both the point of exit from the well casing pipe and the terminus of the overflow are at least 12 inches above the ground grade and the connection to the well casing pipe is watertight. The overflow pipe shall terminate at least 2 pipe diameters above any drain inlet at the well site, in a building or in a building basement. If the overflow is installed at the well head, the overflow shall extend at least 2 feet above the regional flood elevation and a free air gap of at least 2 pipe diameters above the drain shall be provided. The receiving drain shall discharge to the ground or to a gravel pocket at a point at least 8 feet from the well. A funnel receptacle shall be installed on the inlet of the drain to accept all of the overflow water, to prevent splashing and prevent ponding of water around the well casing pipe. If a pump is installed in the well and the well stops flowing during pumping, a screen shall be installed on the overflow pipe.
NR 812.32(9)(d) (d) Complying installations. Illustrations of complying pump installations for flowing wells are shown in Figures 4 to 6 of ch. NR 812 Appendix.

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.
