ABSTRACT:
An apparatus for dispensing a water treating composition into the recirculating water of an evaporative system, such as an evaporative cooler. The water treating composition is contained in a container that is suspended in an inverted condition within the housing of the evaporative cooler with the outlet of the container facing downwardly. One end of a drip line is connected through a sealed closure to the interior of the container, and the opposite end of the drip line terminates above the level of water in the reservoir of the evaporative cooler. A manually adjustable needle valve is connected in the drip line and controls the gravity feed of the liquid composition through the drip line to the reservoir. Through the addition of the treating composition, scaling problems in the evaporative system are minimized, corrosion is eliminated and growth of bacteria and algae is inhibited.
