A water conservation device, kit and method of using is disclosed for use in capturing gray water generated from a drain of a fresh water utility apparatus operationally interconnected connected to a fresh water source and for recycling the captured gray water to a gray water utility apparatus. The device comprises the operationally connected elements of a T-junction pipe, a first shutoff valve, a filter entrance pipe, a water filter apparatus, a filter exit pipe, a storage tank, an overflow pipe, an air vent stack, a second shutoff valve, a bypass pipe, a fresh water feed pipe, a third shutoff valve, a fresh water drain pipe, a fourth shutoff valve, a grey water drain pipe, a water pump, and a primary grey water feed pipe. The kit comprises the unattached elements of a T-junction pipe, a first shutoff valve, a filter entrance pipe, a water filter apparatus, a filter exit pipe, a storage tank, an overflow pipe, an air vent stack, a second shutoff valve, a bypass pipe, a fresh water feed pipe, a third shutoff valve, a fresh water drain pipe, a fourth shutoff valve, a grey water drain pipe, a water pump, and a primary grey water feed pipe and a float valve. The method comprises the steps of adjoining, affixing, associating, attaching, binding, bonding, cohering, combining, conjoining, connecting, consolidating, joining, linking, mating, obtaining, placing, putting, tying, and uniting.

The fluid pressure reduction device of claim 9, in which the inlet section is aligned along the radial disk reference line and includes an inlet recovery zone. 11. The fluid pressure reduction device of claim 1, in which each flow path outlet section includes first and second sub flow outlets fluidly communicating with an associated flow path intermediate section. 12. A fluid pressure reduction device comprising: a plurality of stacked disks having a perimeter and a hollow center aligned along a longitudinal axis; each disk having at least one through-cut flow path extending between the hollow center and the perimeter, the flow path including an inlet section, an outlet section, and an intermediate section extending between the inlet and outlet sections; each flow path intermediate section having a generally spiral shape wherein opposing walls of the flow path intermediate section gradually diverge from one another as the flow path intermediate section advances from the inlet section to the outlet section, and further including a pressure reducing structure and a recovery zone positioned immediately downstream of the pressure reducing structure; and each flow path outlet section includes first and second sub flow outlets fluidly communicating with an associated flow path intermediate section. 13. The fluid pressure reduction device of claim 12, in which the generally spiral shape of the flow path intermediate section is formed by a plurality of flat leg portions. 14. The fluid pressure reduction device of claim 12, in which the pressure reducing structure comprises a restriction. 15. The fluid pressure reduction device of claim 14, in which the restriction comprises a first ridge extending from a first wall of the flow path. 16. The fluid pressure reduction device of claim 15, in which the restriction further comprises a second ridge extending from a second and opposite wall of the flow path. 17. The fluid pressure reduction device of claim 16, in which the first ridge extends farther into the flow path than the second ridge. 18. The fluid pressure reduction device of claim 17, in which the first and second ridges are offset so that the first ridge is positioned upstream of the second ridge. 19. The fluid pressure reduction device of claim 12, in which each flow path comprises multiple pressure reducing structures in the intermediate section and an associated recovery zone positioned immediately downstream of each pressure reducing structure, wherein each pressure reducing structure and recovery zone pair effects a pressure drop stage.
