Abstract

An automatic flush water distribution system for use in an evaporative cooling system includes a water distribution pipe adapted to be connected to a source of pressurized water. The pipe has a plurality of water distribution ports formed therein and a vertical flush pipe is connected at a first end to the water distribution pipe in liquid communication therewith. The flush pipe includes a second lower end and contains at least one valve seat and at least one buoyant float valve located therein between the valve seat and the water distribution pipe. The float valve and valve seat have mating surfaces so that when pressurized water is applied to the water distribution pipe, the float valve is held by water pressure against the valve seat, and when the water pressure is relieved, the float valve floats in the flush pipe, opening the valve and allowing the water to be discharged through the second end of the flush pipe, thereby creating a partial vacuum in the water distribution pipe to draw atmospheric air through the port to dislodge debris therein.
