초록 ▼

A water pump normally used in a system circulating pool water through a filter cartridge 26 is used to clean the filter cartridge by coupling a 3-way or inline valve 32 and a tee 36 in the piping 12 between the pump 16 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 52 secured to a first water discharge wand 58. A circular ring-shaped manifold 64 with an array of discharge apertures 66 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. 5) is then connected to the hose and used to direct water streams onto the outer periphery of the filter cartridge.

1. In a water filtering system having a pump coupled in piping configured to circulate water from a body of water in an open-topped structure, through a filter cartridge in one flow direction to a centrally located discharge chamber within said filter cartridge, and then back to said body of water, comprising in combination therewith:a valve coupled in said piping between said pump and a filter housing of said filter cartridge, said valve having a first position wherein said filter housing receives the entire water output from said pump and a second position for diverting the entire water output of said pump from said filter housing; a flexible conduit for receiving the entire water output from said pump when said valve is in said second position; and a first water discharge wand joined to said flexible conduit for receiving the water output from said conduit, said first water discharge wand having an elongated handle with an internal duct communicating with a circular ring-shaped manifold having an array of water discharge apertures, wherein said flexible conduit and said wand is configured to be manually manipulated such that said manifold can be positioned within said centrally located discharge chamber for directing streams of water radially outward into said filter cartridge in a direction opposite to said one flow direction to hydraulically flush debris from said filter cartridge using the entire pressurized water flow of said pump.
