A valve flush apparatus includes a rigid base designed to removably attach to a body of an irrigation valve. A stem extends outwardly from the base and away from the body of the irrigation valve and may be centrally located on the base. The stem and an aperture in the base may define a water passageway through which water may flow through the body of the irrigation valve and through the valve flush apparatus. A hose may also be included which removably attaches to the stem so as to extend the water passageway of the valve flush apparatus. A method includes flushing a clogged irrigation valve through use of the valve flush apparatus.
