Claim 5:
6. The apparatus of claim 1 wherein said fluid diverter has a cylindrical body including an upper face, a lower face and perimeter surface, said cylindrical body having a open central lumen;
a. said diverter upper surface is adapted to be securely associated within said housing about an upper portion thereof; said diverter upper surface is provided to associate with a fluid diverter controller disposed external to said housing;
b. said diverter lower surface is adapted to receive and be in fluid communication with said spine assembly about said second end; said diverter lower surface having a central opening that is in fluid communication with said open central lumen; said central opening is surrounded by a peripheral channel disposed about the perimeter of said lower surface; said peripheral channel configured to received and securely couple with said spine assembly second end, wherein said central opening is configured to be in fluid communication and continuous with a spine assembly inner lumen; and wherein said peripheral channel is configured to be in fluid communication with a plurality of spine legs defining said spine assembly inner lumen;
c. said diverter perimeter surface having a flow inlet portion defined along said surface, and at least three apertures extending from said perimeter surface including two open apertures and a pressure relief aperture;
i. said flow inlet portion configured to be opposite an inlet opening so as to allow the flow of the upstream un-filtered flowing fluid into the filter housing within a peripheral lumen during the filtering phase;
ii. a first open aperture is configured to align with and provide fluid communication between an outlet opening and said central opening defined about said diverter lower surface through said open central lumen, wherein during the filtering phase said first open aperture receives and conveys the filtered flowing fluid out of filter housing through the outlet opening;
iii. a second open aperture configured to provide fluid communication to said spine legs via said peripheral channel, wherein said second open aperture is utilized during self-cleaning to facilitate cleaning the disc filter media and;
iv. a pressure relief aperture having an opening featuring a pressure relief piston assembly, wherein the piston assembly configured to equalize pressure between said first open aperture and said pressure relieve aperture by opening or closing said opening.
