ABSTRACT:
In a pitless well adapter, an adapter insert from which a flow pipe and pump depends, is normally vertically, slidably and removably held by wedge ribs in an adapter housing. The top surfaces of the adapter insert and adapter housing are similarly formed such that sliding the adapter insert out of engagement with the adapter housing will enable the adapter insert to be deflected into the casing in a manner which will spare damage to the adapter insert. The bottom surface of the adapter insert and the adapter housing are of matching contours so as to permit proper seating of the adapter insert in the adapter housing. The uppermost portion of the wedge ribs are tapered to form a guide surface engageable with the adapter insert upon installation of the adapter insert in the adapter housing.
