Water recycling device for flush toilet use
First Claim
1. A compact, modular control and reservoir unit water recycling system for storing and reusing gray waters for providing flush toilet water supply, the modular unit comprising a full enclosure for the control and reservoir unit having a volumetric capacity sufficient to store adequate water for pattern family toilet use;
- water flow connection means for connecting the enclosure interior with a source of gray water;
flow filtration means within the enclosure in direct flow relationship with the water flow connection means for providing an initial filtering of said gray water;
overflow outlet means connected to the enclosure for draining gray water from the enclosure in excess of a predetermined maximum level;
discharge pipe means for connecting the interior of the enclosure to a flush toilet tank;
an electrically operated pump within the enclosure and in fluid flow connection in said discharge pipe means for pumping said gray water from the interior of the enclosure; and
outlet filter means in said discharge means located within the interior of the enclosure for providing an auxiliary filtering of said gray water prior to entering said pump; and
first electrically operated signal means within the interior of the enclosure for actuating the pump in response to a decrease of water level in the toilet tank to below a designated level; and
flow means for connecting a potable water system of a house to the interior of the enclosure, including electrically operated potable water inlet valve means for controlling the flow of potable water into the enclosure and second electrically operated signal means within the enclosure and operatively connected to the potable water inlet valve means and designed to cause the potable water inlet valve means to open in response to a decrease in water level within the enclosure below said predetermined maximum level and the absence of gray water from said gray water source to said enclosure; and
electrical connection means designed to connect said electrically operated components to a source of electricity.

Abstract
A compact, modular gray water recycling system includes a control and reservoir unit for storing gray water, which is received from a source such as a sink drain, and pumping it to the household toilet as necessary. The single unit houses a pump, flow signals, filters, and an overflow. The system may also utilize a second storage reservoir and separate control unit for added gray water storage. The secondary storage and control units may also be adapted to receive water from an outside source such as rainfall runoff.
