ABSTRACT:
A toilet for conserving water, the toilet having a water storage chamber which includes an expandable diaphragm wall that on filling under household water supply pressure conforms to a wall of a complimentary air chamber separated from the storage compartment by the diaphragm. The chamber communicating with a gated discharge cavity between a trap and a sewage line, wherein water in the storage compartment is released at a high flow rate into a bowl having sedentary waste water, the waste water being exhausted from the bowl into the discharge cavity by a partial vacuum action generated by the contracting diaphragm concurrent with the introduction of the supply water, the waste water being gated from the discharge cavity into the sewer line on reduction of the vacuum pressure, whereby the supply water replaces rather than flushes the waste water.
