ABSTRACT:
A chemical injection apparatus for injecting chemicals into a toilet having a tank, a bowl, an overflow pipe and a refill hose. In one embodiment, the apparatus includes a housing having an inlet adapted to couple to the refill hose to receive refill water and an outlet that provides chemically treated water, an inner chamber, disposed within the housing, that is adapted to contain a chemical tablet, and a first tube coupled between the inlet and the outlet of the housing, the first tube having a dispensing hole that dispenses at least a portion of the refill water from the first tube into the housing, the dispensing hole being constructed and arranged such that the water dispensed from the dispensing hole contacts the chemical tablet to dissolve a portion of the chemical tablet to create chemically treated water, the first tube also having a venturi near the outlet end and a suction hole near the venturi. The apparatus further includes a sump area disposed within the housing such that at least a portion of the chemically treated water collects in the sump area, and a second tube having a first end disposed in the sump area and a second end coupled to the suction hole of the first tube. The venturi is arranged within the first tube such that the flow of the refill water through the first tube causes the chemically treated water to be drawn from the sump area through the second tube and mixed with the refill water in the first tube.
