A cleaning mechanism for a filter cartridge is described, which includes a tubular flow duct, having a series of flow ports, spaced along its length. One end of the flow duct is closed, while the other, open end of the flow duct, has a hose coupling, that can be screwed onto a conventional hose, so that pressurized water, or other cleaning liquid, can be admitted to the flow duct. An annular filter cartridge, is mounted on the flow duct, between two circular disks carried at opposite ends of the flow duct. One of these disks, is removable from the flow duct, in order to permit the filter cartridge, to be installed onto the flow duct, or removed from the flow duct. When a pressurized cleaning liquid is admitted to the flow duct, the liquid pressure forces the liquid radially outwardly, through the filter cartridge, so as to dislodge contaminants from the annular filter body.

A mechanism for cleaning a filter cartridge, wherein the filter cartridge comprises, an annular filter body, having two opposing end caps, an inner annular surface, and an outer annular surface; said cleaning mechanism, comprising, an elongated tubular flow duct, having a number of ports, located at spaced points therealong; said flow duct having a first closed end, and a second open end; said first closed end, being externally threaded; a first annular disk, having internal threads matable with the external threads on said flow duct, whereby said first annular disk can be screwed onto said first end of said flow duct; a second annular disk affixed to said flow duct, near its second end; a hose coupling having a swivel fit on said second end of said flow duct, whereby a hose can be connected to said flow duct to deliver a pressurized stream of liquid into said flow duct; said flow duct and said annular disks, being manually positionable as a unit, so that an annular filter body can be telescoped onto said tubular flow duct, after which said first annular disk can be threaded onto said flow duct, to cause said annular disks to exert clamping pressure on the end caps of said filter body; and the external diameter of said flow duct being less than the corresponding diameter of the inner annular surface on said filter body, so that when the filter body is telescoped onto the flow duct, pressurized liquid can flow outwardly from said flow duct, through the filter body, thereby forcing contaminants from said filter body through the outer annular surface of said filter body.
