Abstract
A water recycling system primarily adapted for use in shower facilities enabling the user to increase both the time duration of a shower and the quantity of water experienced by a user, by maintaining water in a semi-closed system, while both maintaining water and energy conservation. The system preferably operates with fresh and recirculated hot water. The system utilizes spent hot shower water located in the catchment area of a shower or tub and recycles this water to one or more spray heads located at or in the proximity of the regular water dispensing head or so-called "spray head" of that shower. A selected water temperature can be maintained by periodically introducing fresh water or continuously introducing the fresh water at a very low flow rate from a fresh water source, and mixing that water with the recycled water from a water catchment area. Recycled water can also be re-heated and issued again. The apparatus of the system may be provided with an adapter for quick connect and disconnect such that the apparatus can be moved from shower to shower. A manifold forming part of the apparatus includes a check valve arrangement to preclude gray water or spent hot water from ent…
