ABSTRACT:
A water reclamation apparatus for recycling water in a system including a reclamation tank for holding water to be recycled, a first conduit for conveying water to the reclamation tank, a second conduit for conveying water from the reclamation tank, an outlet hose extending from the second conduit to a point beneath the level of the water in the reclamation tank, the outlet hose including two check valves operatively connected in series to allow water to flow through the outlet hose from the reclamation tank, and to prevent water from flowing into the reclamation tank from the outlet hose under conditions where one of the check valves is held in an open position. The outlet hose is flexible and can be extended through an access portion of the reclamation tank to allow the check valves to be serviced.
