Abstract
An automatic flushing device for an evaporative cooling system contains a water sump, circulating pump, and float-operated water makeup source. A small, adjustable portion of the return flow enters a separate timing reservoir. When the timing reservoir is full, water from the well and the sump are flushed from the system through a siphon tube which communicates with both chambers.
