A securing device for contents of a wheelbarrow for preventing the content of a wheelbarrow from falling out of the wheelbarrow. The securing device for contents of a wheelbarrow includes a generally flexible panel having a first end edge and a second end edge. A first hook is attached to the first end edge. A tubular member has a first end and a second end. A slot extends through a peripheral wall of the tubular member. A spindle is rotatably mounted in the tubular member. The second end edge extends through the slot and is attached to the spindle. A second hook is attached to the tubular member. The first and second hooks are attached to the upper edge of a wheelbarrow such that the panel is extended over the wheelbarrow. ring providing yielding frictional resistance to movement of said valve assembly relative to said passage to thereby dampen vibration of said valve assembly during a closing phase of the flush valve operating cycle and control the flow of water through the flush valve, and wherein the annular member is positioned adjacent to and held in place by the shoulder, and the refill ring is held in position between the annular member and said valve assembly. 2. The apparatus of claim 1, wherein the refill ring is an O-ring made from at least one of rubber and polymeric material. 3. The apparatus of claim 1, wherein the refill ring is integrally formed on an underside of said diaphragm. 4. The apparatus of claim 1, wherein the guide member is positioned within said passage and the refill ring positioned to co-act with the exterior of said guide member. 5. The apparatus of claim 1, wherein the annular member does not contact the passage during the flush valve operating cycle. 6. The apparatus of claim 1, further comprising: a plurality of guide member legs attached to said guide member; a second annular member attached to said guide member; and a resilient solid flow control ring, wherein the flow control ring is held in position between the plurality of guide member legs and the second annular member, and is configured to be in constant contact with said passage during the entire stroke of the valve assembly during the operation of the flush valve, whereby the flow control ring provides yielding frictional resistance to movement of said valve assembly relative to said passage to thereby dampen vibration of said valve assembly during the entire flush valve operating cycle. 7. The apparatus of claim 6, wherein the second annular member does not contact the passage during the flush valve operating cycle. 8. The apparatus of claim 6, wherein the guide member is positioned within said passage and the refill ring is positioned to co-act with the exterior of said guide member, the refill ring comprising an O-ring made from at least one of rubber and polymeric material, the refill ring held in place between an annular member co-acting with an exterior of said guide member and said diaphragm of said valve assembly and the flow control ring comprising an O-ring made from at least one of rubber and polymeric material, the plurality of guide member legs depending from the exterior of said guide member, the flow control ring held in place between the second annular member co-acting with the exterior of said guide member and the guide member legs. 9. The apparatus of claim 8, wherein the refill ring is integrally formed on an underside of said diaphragm. 10. A flush valve, comprising: a valve body defining an inlet connection and an outlet connection; a valve assembly positioned in the valve body and separating the inlet connection and the outlet connection, with the valve assembly configured to have a pressure difference applied across the valve assembly and positioned to control the flow of water through the valve body; the valve assembly comprising: an annular flexible diaphragm having a mounting portion at a peripheral edge for mounting the valve assembly within the flush valve, the diaphragm having a first side and a second side and defining an orifice extending from the first side to the second side and a sealing surface on the second side and adjacent to an inner edge of the diaphragm and an annular guide member having two ends, said guide member defining a shoulder, the first end attached to an inner edge of the diaphragm adjacent to the sealing surface and defining a relief valve seat and central opening, and the second end extending from the second side of the diaphragm; a resilient solid refill ring attached to the exterior of the guide member abutting the sealing surface of the diaphragm; an annular member configured to support and co-act with the refill ring; a relief valve resting above and extending through the c
