Abstract
One embodiment of a sediment filter (10) includes a filter head (12) having an inlet opening, an outlet opening, a drain outlet (34) , and a sump connector, the sump connector includes a first opening in fluid communication with the inlet opening and a second opening in fluid communication with the outlet opening, a cylindrical filter (28) having a cylindrical screen, an upper end having a filter outlet opening, and a lower end having a tube opening, the filter outlet opening in fluid communication with the sump connector second opening, a sump receptacle (26) having a lower end having a sump and an upper end having an opened end, the open end having a head connector for coupling with the sump connector, and a tube (30) having a lower end and an upper end, the tube extends through the cylindrical filter, with the lower end ending into the sump and the upper end extending into the filter head, with the upper end in fluid communication with the drain outlet, whereby sediment may be drained from the sediment filter with water flow from the head inlet opening, down into the sump, up through the tube and out the head drain outlet.
