A tap head device comprising a pipe body with a first canal where the fluid passes through, wherein the pipe body enables the fluid flow to exit of the tap head device vertically downwards when in closed position, and a head with a union nut with a thread inside the union nut that enables the tap head device to be mounted on a tap system characterized by a junctional body connecting the union nut to the pipe body, wherein the junctional body and the connected pipe body comprise a lateral passage allowing for a fluid exit and a central screw hole, a rotating main body encompassing the pipe body and being rotatable around the pipe body, the pipe body and the rotating main body are kept together by a screw inserted in the screw hole and preventing the rotating main body from falling apart from the pipe body, while at the same time enabling the rotating main body to rotate around the pipe body, a second canal and a third canal of the rotating main body that enable to deviate the fluid flow laterally and upwards in an open position disabling a vertical fluid exit, wherein the rotation of the rotating main body moves the tap head device from the closed position that enables a vertical fluid exit and that closes a connecting aperture of the second canal hermetically, to the open position that enables to deviate the fluid flow laterally and upwards and that closes a forth canal disabling the vertical fluid exit; a trench milled in a base part of the rotating main body, said forth canal being part of the trench thereby providing for a smooth transition of the fluids flow between the closed and open position, and the aperture being situated vis-à-vis or at least offset to the trench, wherein for the open position, the main body is rotatable in such a way that the aperture communicates with the first canal inside the pipe body. a junctional body connecting the union nut to the pipe body, wherein the junctional body and the connected pipe body comprise a lateral passage allowing for a fluid exit and a central screw hole, a rotating main body encompassing the pipe body and being rotatable around the pipe body, the pipe body and the rotating main body are kept together by a screw inserted in the screw hole and preventing the rotating main body from falling apart from the pipe body, while at the same time enabling the rotating main body to rotate around the pipe body, a second canal and a third canal of the rotating main body that enable to deviate the fluid flow laterally and upwards in an open position disabling a vertical fluid exit, wherein the rotation of the rotating main body moves the tap head device from the closed position that enables a vertical fluid exit and that closes a connecting aperture of the second canal hermetically, to the open position that enables to deviate the fluid flow laterally and upwards and that closes a forth canal disabling the vertical fluid exit; a trench milled in a base part of the rotating main body, said forth canal being part of the trench thereby providing for a smooth transition of the fluids flow between the closed and open position, and the aperture being situated vis-à-vis or at least offset to the trench, wherein for the open position, the main body is rotatable in such a way that the aperture communicates with the first canal inside the pipe body.
