Abstract: A system for supplying water to a user at a wash basin from a main water line, the system including a splitter having a main water intake, a high flow output port and a lower flow output port. The high flow port is coupled to a high flow water line and a high flow outlet while the low flow port is coupled to a low flow water line and a low flow water outlet. First and second electrically controlled valves control the flow of water out of the high flow and low flow ports, respectively. A control unit is coupled to the first and second valves. The control unit is further configured to close both valves and to switch which of the valves is open and which of the valves is closed so that only one valve is open at a time.
