An embodiment includes a valve with a filter in which the flow of water through the valve is stopped by lowering a filter within the valve. This movement of the filter allows a poppet valve to close, stopping the flow of water. Subsequent raising of the filter holds the poppet valve in the open position, allowing the flow of water through the filter for further use. Embodiments are found in drinking fountains and facilitate the maintenance of the drinking fountain by allowing a technician to shut off the water using a screwdriver without requiring the removal of the fountain cover. |
