PRIMING WATER-SUPPLY WELL PUMPS

A pump that requires priming for ordinary use must not be installed on a water-supply well unless the well is only used for a water irrigation system. An irrigation well pump must be primed only with water free of contamination and carrying a measurable chlorine residual. An irrigation well equipped with a centrifugal pump may be primed without chlorination when the pump is filled with water taken directly from the well.
