Claim Text:
1. A water distribution system comprising: a water storage tank; a primary water treatment unit; at least one diverter valve; water conduits fluidly coupling a fill port to the at least one diverter valve, fluidly coupling the primary water treatment unit to the storage tank, and fluidly coupling the at least one diverter valve to at least one point of water use device; a diverter valve conduit fluidly coupling the at least one diverter valve to the primary water treatment unit; means for pressurizing water in fluid communication with the storage tank; and a four port fill valve and a water drain conduit fluidly coupling the storage tank to the fill valve, the fill valve having two bores and being movable between a fill position wherein a first bore is in fluid communication with the water conduit fluidly coupling the fill port to the diverter valve and a second bore is in fluid communication with a drain port and the storage tank via the drain conduit, and a supply position wherein the fill and drain ports are not in fluid communication with the system; the at least one diverter valve being movable between a fill position wherein water flows from the fill port to the primary water treatment unit in one direction through the diverter valve conduit, and a supply position wherein water flows from the primary water treatment unit to the at least one point of water use device in an opposite direction through the diverter valve conduit.
