A tap connection unit, to which an auxiliary feed water connection tube is connected, is provided to reduce installation cost by integrally forming an auxiliary feed water connection unit to the tap connection unit. In a tap connection unit, to which an auxiliary feed water connection tube, is connected, a tube(T) for feeding service water to a water purifier/softener or a bidet is installed between a water outlet side of a water pipe(P) and a tap and is connected to the tap connection unit of a crank type with a stop valve. In the stop valve, a valve disk(320) is attached to the front end of an empty valve stem(310). Auxiliary feed water inlets(330), a male screw part, an O-ring groove, a male screw part(370), and a handle(380) are formed to the rear end from the front end to the outside of the valve stem. The male screw part is screwed to a female screw part(132) in a stop valve installation unit(130) of the tap connection unit. An O-ring(352) to be adhered closely to the inside(134) of the stop valve installation unit of the connection unit is fitted into the O-ring groove. The movement-preventing nut(360) for preventing movement after controlling an opening and closing state of the stop valve is screwed to the male screw part, and the handle rotates the stop valve from the outside. A connection part(390), to which the tube for feeding auxiliary feed water to be connected to the water purifier/softener or the bidet is combined by a one-touch method, is arranged to the rear end of the valve stem.
