(A) Pump installation shall be in accordance with the following regulations.
(1) Hand pumps. All hand pumps, stands or similar devices shall be installed so that no unprotected opening connecting with the interior of the pump exists. The pump spout shall be of the closed downward-directed type. All hand pumps shall be bolted to a mounting flange securely fastened to the well casing. The top of the casing shall extend at least one inch above the face of the flange.
(2) Power-driven pumps. All power-driven pumps located over wells shall be mounted on the well casing, a pump foundation or a pump stand so as to provide an effective well seal at the top of the well. Extension of the casing at least one inch into the pump base will be considered an effective seal; provided, the pump is mounted on a base plate or foundation in such a manner as to exclude dust and insects, and the top of well casing is at an elevation at least two feet above any known flood water level.
(a) Where the pump unit is not located over the well and the pump delivery or suction pipe emerges from the top thereof, a water-tight expanding gasket or equivalent well seal shall be provided between the well casing and piping. A similar water- tight seal shall be provided at the terminal for a conduit containing a cable for a submersible pump. See § 52.03(B)(1)(g) for casing top above ground surface.
(b) All submersible pumps shall have one check valve located on the discharge line above the pump and inside the casing. If the discharge pipe is at least 12 inches above the ground and slopes to drain into the well, the check valve may be located in the house.
(c) Pitless adapters with below-ground discharge may be used. See § 52.03(B)(1)(h) for details of construction. The covered top of the adapter casing section shall extend 12 inches or more above the ground surface or 24 inches above maximum high water. There shall be no openings through the walls of the well or adapter casing for vents, wires, air lines or the like.
(3) Pumphouses. Unless the power-driven pump installation is of weather-proof and frost-proof construction, it shall be protected by a structure which permits access to the pump for maintenance and repair work. The pumphouse floor shall be constructed of impervious material and shall slope away in all directions from the well or suction pipe.
(4) Protection against freezing. Discharge lines and vacuum lines from the well to the foundation of heated buildings shall be protected against freezing.
(5) Well vents. All well vent openings shall be piped water-tight to a point not less than 24 inches above any known flood water level and, in any event, at least six inches above the well casing. See § 52.03(B)(1)(g). Such vent opening and piping shall be of sufficient size to prevent clogging by hoarfrost and in no case less than ¼-inch in diameter. The terminals of vent pipes shall be shielded and screened to prevent the entrance of foreign matter and preferably turned down. If toxic or inflammable gases are vented from the well, the vent shall extend to the outside atmosphere at a point where the gases will not produce a hazard. Openings in pump bases shall be sealed water-tight.
(6) Sampling faucets. In all pressure water systems, provision shall be made for collection of water samples ahead of chlorination, or any other treatment, by installation of a faucet on the discharge side of and as close as possible to the pump. The sampling faucet shall have a smooth turned-down nozzle. A hose bib shall not be used. All-brass pet cocks with 90-degree turned-down spigots may be acceptable as sampling taps.
(7) Suction pipes connecting pump and well. All buried suction pipes, unless deeper than ten feet below the ground surface, shall be enclosed in a pipe conduit having a minimum wall thickness equivalent to a casing of same size. They shall be located from sources of contamination in accordance with the distances specified in § 52.03(A). No suction line shall be located beneath a sewer. An exposed suction pipe, as in a basement room, shall be 18 inches or greater practicable distance above the floor but need not be kept any specified distance horizontally from a cast iron sewer.
(8) Materials prohibited. No material may be used in the well or pump installation that will result in the delivered water being toxic or having an objectionable taste or odor. Flexible or nonrigid plastic pipe shall not be used for suspending submersible pumps. Plastic pipe shall not be used unless bearing the approval of the National Sanitation Foundation and unless having the physical properties required to withstand the torque and load to which it is subjected.
(9) Offset pumps. Offset pumps or pressure tanks shall be located where they are readily accessible. They shall not be located in a crawl space unless the crawl space is drained to the ground surface beyond the crawl space, either by gravity or means of a sump pump, and a minimum of four feet of clear working space is provided between the floor of the crawl space and the floor joist overhead. If located in a crawl space, the pump or pressure tank shall be located within five feet of the point of entry. The access opening should be at least two feet high and two feet wide.
(B) All buried suction pipe shall be located from sources of pollution in accordance with the distances specified under § 52.03(A).
(C) Hand pumps shall be provided with a pump platform at least 48 inches square and four inches thick and reinforced with wire mesh. The upper surface of the platform shall be above grade and shall have a one-inch crown for drainage.
(D) A pressure tank with a minimum storage capacity of 42 gallons per dwelling unit shall be installed for each well. Storage capacity for buildings other than dwellings shall be approved by the Health Department on the basis of the use of the property.
(E) Pump bearing lubrication shall be designed to prevent contamination of either the water supply or the lubricating medium.
