ABSTRACT:
A liquid filtering apparatus which reduces or eliminates the need for regular manual cleaning or backwashing. Backwashing of the filter occurs automatically in response to sensed conditions of filtering. The filtering apparatus includes a chamber, and a filter element in the chamber, a valve for directing liquid through the filtering element in a first direction to filter the liquid. The valve reverses the direction of liquid flow through the filtering element when excessive resistance to flow through the filter element occurs.
