Water well case head adapter

A water well case head adapter attaching to a casing head of a newly installed water well casing further providing an air tight seal to secure a pressurized air hose to purge the water well casing of unsanitary water prior to use for drinking water, said water well case head adapter comprising:

• a pair of identical half cylinder bodies, each body defining a lower threaded outer surface, an upper outer surface, a lower smooth inner surface, an upper expanded inner cavity, and a pair of lateral edges;
• a clamp recess defined within said upper outer surface providing for the installation of a clamp to join each of said half cylinder bodies together along said lateral edges, said half cylindrical bodies forming a cylinder;
• a lower ridge defined between said lower smooth inner surface and said upper expanded inner cavity, wherein said upper expanded inner cavity provides a larger diameter than said lower smooth inner surface;
• a pair of half cylinder baffle segments, each said-baffle segment defining a lower surface, a plurality of flexible horizontal wafers, each wafer defining an inner semicircular notch, the notches vertically aligned to form a linear bore when said baffle segments are joined together and securely installed within said upper expanded inner cavity, with said lower surfaces of said joined baffle segments seated upon said lower ridge and forming an air-tight seal against said upper expanded inner cavity and said flexible horizontal wafers pressing against one another forming an airtight seal except for said linear bore, wherein said lower threaded outer surface of said joined half cylinder bodies engage inner threads of said casing head of said water well casing and said air hose is inserted within said linear bore forming an air-tight seal between said baffle segments and an outer surface of said air hose introducing pressurized air from an attached air compressor through said air hose into said well casing, forcing said unsanitary water within said well casing upward at phasic depths to be purged through a water outlet tube within said well casing until such time as said unsanitary water has been evacuated from said well casing with only sanitary water left within said well casing.
