Abstract
A water flow regulation system includes a pair of water valves having turnable stems for controlling water flow through the valves and a pair of pinions, one fixed to each of the valve stems. A toothed rack is provided which is sized and configured for engagement with the pinions. A housing supports the valves and rack with teeth of both pinions engaging the rack teeth in order that translational movement of the rack causes simultaneous rotation of the pinions with concomitant simultaneous opening and closing of the valves. A remote control and a sheathed cable interconnecting said remote control and the rack are provided for operation of the system.
