Abstract
A water pump normally used in a system circulating pool water through a filter cartridge is used to clean the filter cartridge by coupling a 3-way or inline valve and a tee in the piping between the pump and the filter. In a first valve position, the filter housing receives the entire water output from the pump, and in a second position, the entire water output of the pump is diverted to a flexible hose secured to a first water discharge wand . A circular ring-shaped manifold with an array of discharge apertures directs streams of water radially outward into the filter cartridge in a direction opposite the normal flow of water for hydraulically flushing debris from the filter cartridge. A second wand with a C-shaped manifold (FIG. ) is then connected to the hose and used to direct water streams onto the outer periphery of the filter cartridge.
