A chemical dispensing apparatus for use in delivery of a treatment solution includes a housing configured to be mounted to a wall surface and main fluid passage fitted with an inlet hose coupling at one end and fitted with an outlet hose coupling at an opposite end. A control valve is disposed across the main fluid passage at an upstream location and a flap valve is disposed across the main fluid passage at a downstream location of the control valve. A chemical mixing fluid passage is connected at one end to the first control valve and connected at an opposite end to the flap valve. A siphon tube connects a fluid accumulator and the chemical mixing fluid passage such that a flow of fluid through the chemical mixing passage results in a quantity of liquid chemical contained in the fluid accumulator being drawn through the siphon tube and into the flow of fluid through chemical mixing fluid passage. |
