1. The pumping capacity of the pump shall be consistent with the intended use and yield characteristics of the well. 2. The pump and related equipment for the well shall be conveniently located to permit easy access and removal for repair and maintenance. The base plate of a pump placed directly over the well shall be designed to form a watertight seal with the well casing or pump foundation. The r,•e•r g and elegy+rinal . . - used in connection with the pump shall meet all appliGable underwriters SpeG'f'Gat'GRs and all ether a p"Gahle state and- lenal ne.Jes 4. In installations where the pump is not located directly over the well,the annular space between the casing and pump intake or discharge piping shall be closed with a watertight seal. 5. The well head shall be equipped with a screened vent to allow for the pressure changes within the well unless a suction lift pump or single-pipe jet pump is used or artesian flowing well conditions are encountered. 6. The person installing the pump in any water supply well shall install a threadless sampling tap at the wellhead for obtaining water samples except: a) In the case of suction pump or offset jet pump installations the threadless sampling tap shall be installed on the return (pressure)side of the pump piping; and b) In the case of pitless adapter installations, the threadless sampling tap shall be located upstream of the water storage tank. The threadless sampling tap shall be turned downward, located a minimum of 12 inches above land surface,floor, or well pad, and positioned such that a water sample can be obtained without interference from any part of the wellhead.

In accordance with NCGS 143-138 (b17)the comment[VH65]:SPECIFIES THE ELECTRICAL scope of electrical work which may be performed by a certified well contractor WORK THAT CAN BE DONE BYA WELL CONTRACTOR-BY REFERENCE ONLY includes only the connection or disconnection of a well system to either the plumbing served by the well system or the electrical service that serves the well system: the well, the pressure tank,the pressure switch, and all plumbing and electrical equipment in the well and between the well, pressure tank, and pressure switch.An electrical box is required for wiring connected at the well head. 10. Only potable water shall be used for priming the pump. 30
