Summary: | A bypass orifice and filter for use in the diaphragm of a toilet room flush valve includes an orifice member adapted to be mounted in the flush valve diaphragm, and a filter element attached to the upstream side of the orifice member. The orifice member has a metering restriction to limit the flow of water therethrough and the filter element has a plurality of openings therein in communication with the orifice member metering restriction. The smallest dimension of the openings in the filter element are less than the smallest dimension of the metering restriction so that any particle in the water passing through the filter element will pass through the metering orifice. In some embodiments the orifice member and filter element are an integral unit. |
