Abstract

PURPOSE: To obtain a tap equipment capable of preventing occurrence of bacteria, by so constituting that a pure water may return via a return pipe when the pure water is checked to flow into a pure water supply opening by a tap opening/closing valve disc which moves up and down in a pure water intake pipe. CONSTITUTION: In the condition that a lever 5 is not pressed down, a supply by-path pipe 11 is closed by a blocking part 15 of a tap opening/closing valve disc 12; a pure water coming in through a pure water intake pipe 7 passes through a return by-path pipe 10 through a pure water supply hole 14 and returns from a return pipe 8 to a return pipe 2. With the lever 5 pressed down and a valve disc 12 made to move down so as to agree the pure water supply hole 14 with an opening of the supply by-path pipe 11, the pure water flows to a pure water supply opening 4 via a connection pipe 13.
