Abstract: Described is a method for installing a gray water reclamation system in an existing plumbing infrastructure. A flexible conduit 26 is connected to the drain of a gray water source by moving the flexible conduit through an access 36 in the plumbing infrastructure and through the drainage conduit 41 to the drain where one end of the flexible conduit is coupled thereto. The other end of the flexible conduit is located adjacent the access and is in fluid communication with a filtration apparatus 27 and a storage vessel 28 so that the gray water may be filtered and then stored. A plumbing snake may be used to move the flexible conduit through the existing plumbing infrastructure.

Abstract: An apparatus for reclaiming gray water includes a drainage conduit (41), a main drainage conduit (35), a gray water conduit (26), a filter apparatus (27), and a storage vessel (28). The drainage conduit is coupled to the drain (40) of a source of gray water (21) and to the main drainage conduit. The gray water conduit extends from the drain into and through the drainage conduit and then into and through a predetermined length of the main drainage conduit to the filtering apparatus. The vessel is provided for receiving and storing filtered gray water from the filtering apparatus. Preferably, the gray water conduit includes a funnel (45) for conducting gray water from the drain and into the proximal end of the gray water conduit. The funnel includes a grating (50) and at least one opening (51) for permitting the gray water to flow into the drainage conduit, bypassing the gray water conduit, in case the gray water conduit becomes obstructed.
