ABSTRACT:
A pitless well adapter is provided having a main body portion with vertical and horizontal openings which are interconnected through the main body to provide a passageway for water from the well into a horizontal supply pipe. The adapter is secured in a well casing so that the horizontal opening is in registry with a hole in the side of the casing, and an outer connector member is secured around the outside of the casing to provide a means for connecting the horizontally extending pipe. The main body of the adapter is held in position inside the casing by thrust developed between the adapter and opposite sides of the casing wall. A pair of lever arms are pivotally interconnected and mounted on the main body opposite the horizontal opening with an end portion of one of the lever arms being secured to the main body and an end portion of the other lever arm being secured to a slide member mounted for vertical sliding movement on the main body and engaged with a threaded member rotatably mounted in the main body. Rotation of the threaded member causes the lever arms to be pivoted outwardly away from the main body so as to engage the side of the casing and develop thrust holding the main body in position.
