Abstract
A well water recirculation valve comprising an in-line check valve and a calibrated orifice through the body of the check valve. The orifice communicates through the body of the check valve into an unchecked end thereof. In use in a water well having a submersed pump, the recirculation valve is spliced into a well pipe at a location below the top of a well but above an average static water level in that well. The recirculation valve of the present invention recirculates a portion of the water pumped through the well pipe back into the well for preventing a stagnation of a head portion of that well.

In a well water aeration system having a submersed pump and a well water recirculator spliced into a well pipe at a location below the top of the well but above an average static water level in said well, for recirculating a portion of the water pumped through said pipe back into said well for preventing a stagnation of a head portion of said well, the improvement being that said well water recirculator comprises essentially an inn-line check valve and an orifice communicating through a body of said check valve into an unchecked portion thereof, said orifice being a calibrated opening, a dimension of which is relative to a depth of said in-line check valve in said well.
A water well recirculation valve for splicing into a well pipe of a well having a submersed pump, at a location below the top of a well but above an average static water level in said well, for recirculating a portion of the water pumped through said well pipe back into said well for preventing a stagnation of a head portion of said well, said well water recirculation valve comprising an in-line check valve and an orifice communicating through a body of said in-line check valve into an unchecked portion thereof, said orifice being a calibrated opening, a dimension of which being relative to a recommended installation depth of said in-line check valve in said well.
A manufacture of a well water recirculation valve comprising the steps of:
- obtaining a commercially available in-line check valve;
- drilling and tapping a hole through a body of said in-line check valve, into an unchecked portion thereof;
- mounting a 90.degree. street elbow fitting in said hole, with a female thread portion of said elbow fitting oriented toward an inlet end of said check valve;
- machining a calibrated orifice having a shape of a threaded hollow stem;
- mounting in said female thread portion said calibrated orifice.
