TITLE Water Disinfecting System ABSTRACT OF THE DISCLOSURE A method and apparatus for delivering disinfectant in a liquid form to a well of a water system is disclosed including a venturi having a suction side in fluid communication with a source of disinfectant such as chlorine. A flow of water is provided through the venturi between the pressurized side of the water system and the well when a pump is drawing water from the well and delivering the water to the pressurized side of the water system. Specifically, a solenoid valve is provided in the lines between the pressurized side of the water system and the venturi and is electrically controlled by the pressure switch which also controls the pump. In the preferred form, a timer is provided electrically intermediate the solenoid valve and the pressure switch to allow water flow through the solenoid valve only during selected times of pump actuation to allow adjustment of the rate at which the disinfectant is delivered. To prevent freezing of the output line, a bypass line may be provided between the pressurized side of the water system and the output line bypassing the solenoid valve and the venturi and providing a continuous flow of water therethrough. In an alternate form, a heat tape for conducting heat to the output line may be provided as part of or within a conduit in which the output line is slideably received. A check valve may be provided to prevent backflow into the source of disinfectant when flow is interrupted. Further, a flow meter may be provided to indicate proper operation of the water disinfecting system.
