Abstract

A diatomaceous earth filter cleaner for cleaning flex tubes attached to a tube sheet of a diatomaceous earth filter. The diatomaceous earth filter cleaner has a hollow tube, a blast jet housing, an inner diameter scrub brush, and a fitting at an end of the hollow tube for coupling a hose connected to a water supply. The hollow tube of the diatomaceous earth filter cleaner has a length with a first end and a second end for receiving a flex tube. The blast jet housing is attached to the first end of the hollow tube and comprises an angled lip and a restricted orifice formed by an inner circumference of the blast jet housing for receiving a flex tube. The inner diameter scrub brush is received within the inner circumference of the blast jet housing and has an orifice for cleaning an outer circumference of the flex tube.
