calibrated orifice through the body of the check valve. The orifice communicates throughthe body of the check valve into an unchecked end thereof. In use in a water well having asubmersed pump, the recirculation valve is spliced into a well pipe at a location below thetop of a well but above an average static water level in that well. The recirculation valveof the present invention recirculates a portion of the water pumped through the wellpipe back into the well for preventing a stagnation of a head portion of that well.
