Abstract: A flow control washer for use in a plumbing fixture such as a shower head is formed of a distortable rubberlike material and has a generally cylindrical shape. There are a plurality of independent water passages through the washer, with the passages being axially aligned. A distortable projection is positioned between each pair of passages. The pressure of water upon the washer causes the projections to distort, partially restricting the openings into the passages, thus controlling the flow of water through the plumbing fixture.
