A pitless adapter assembly for a water well system or the like operable by a pump suspended in the well below the pitless adapter assembly to pump underground water upwardly through a plastic supply pipe to a feed pipe through a fitting in a well casing, and including a housing having a generally right-angle flow path therein defined by an housing inlet and a housing outlet for interconnecting the supply pipe with the feed pipe through the well casing. The housing includes an integrally-formed eyelet for receiving and retaining a safety cable to which the pump is suspended in the well and a plurality of annular serrations formed in the walls of the housing surrounding the housing inlet for receiving and retaining an upper end of the feed pipe. Interior walls of the housing defining the flow path extend between the housing inlet and the housing outlet and are curved to provide right-angle turn which reduces turbulence in the water flowing through the housing from the supply pipe to the feed pipe.
