ABSTRACT:
A device for use in a swimming pool to continuously dispense chlorine for sanitizing the water is disclosed which has a metering valve designed for precise adjustment of the rate of dispersion of the chemical contained in the feeder. The metering mechanism is made of two segments, with a metering valve cap fitting over a metering valve body to adjust the apertures in the metering mechanism. Precise control is afforded both by a screw-type adjustment of aperture size and by a prevention of inadvertent readjustment of the metering mechanism caused by the device being bumped.
