ABSTRACT:
A root feeder for dispensing a hydro-fertilizer solution is provided. The head of the feeder includes a dual handle body formed integrally with a fertilizer mixing bowl. A back-flow preventer valve and a manual cut-off valve are connected in series inside the hollow body of one of the handles providing flow control of the water. A stepped bore is provided in which the valves are securely seated and sealed. A cap on the end of the handle includes an integral sleeve to provide additional support for the valves. The flow path for the water is through the sleeve and the valves directly into the mixing bowl. The back-flow preventer valve is sealed by an O-ring in the bore and is positioned adjacent the bowl so that full sealing force around the valve is obtained and prevention of back-flow is assured. A flow plate and elastomer diaphragm form the back-flow preventer valve; whereas, the cut-off valve is a ball type. The sleeve formed on the cap retains the ball in position in the cut-off valve and secures the position of the valves in the bore. The cap is retained by a snap action connection on the sleeve and at least one resilient prong with a hook that seats in an aperture in the handle.
