ABSTRACT:
A water filter includes a main housing defining a primary filter chamber in which is disposed an elongated tubular inner or secondary filter. Media arranged in the direction of flow includes, within the primary filter, layers of relatively coarse and fine flint gravel followed by a substantial layer of packed charcoal. The inner filter includes a substantial layer of packed charcoal and discrete layers of fine and coarse gravel near the outlet of the inner filter. The arrangement of media provides for repeated backflushings without contaminating the primary filter media. The main filter housing includes spaced apart head members which are interconnected by cylindrical tubular liners and an outer tubular shell disposed around the inner liners. The filter inlet and outlet conduits are provided with self-sealing quick disconnect coupler members for coupling the filter to a diverter circuit from the main water line or to a suitable circuit for backflushing operations.
