(a) The licensee shall inform the landowner and well
owner that the landowner and well owner are responsible for complying

casing and the pressure tank. Either a check valve or an air gap,
as applicable, shall be required on all irrigation well pumps whenever
a pump is installed or repaired. All wells shall have either a check
valve, or an air gap as applicable.
(c) Wells shall be vented with watertight joints except

(1) The casing vent shall be screened and pointed downward.
(2) Vents may be offset provided they meet the provisions
of this rule.
(3) Toxic or flammable gases, if present, shall be
vented from the well. The vent shall extend to the outside atmosphere
above the roof level at a point where the gases will not produce a
hazard.
