  • the handle 11 may also be rotatable in a generally horizontal plane, in order to control the temperature of water flowing through the tap 10.
  • the tap 10 also includes a valve assembly 12 which is moveable between an open condition, in which the outlet pipe 2 is fluidly connected to the transfer pipe 1, such that water is permitted to flow from the transfer pipe 1, into the outlet pipe 2, to be dispensed; and a closed condition, in which the transfer pipe 1 and the outlet pipe 2 are fluidly disconnected, so as to prevent the flow of water into and,out of the outlet pipe 2.
  • the valve assembly 12 is received in the opening 14 of the water transfer pipe 1, at an in use upper end thereof, and is movable between the open and closed conditions by operation of the handle 11.
  • connection device includes a substantially hollow connection screw 3, having a first end 31 and a second end 32.
  • An outer surface of the connection screw 3 is substantially circular in cross-section, and is threaded.
  • the connection screw 3 has an opening which extends through the screw, between the first end 31 and the second end 32.
  • the opening is substantially dodecagonal in cross-section, for engagement with a suitable Allen key. It will be appreciated that other shaped openings can be provided.
  • a substantially circular aperture 13 is provided in the perimeter wall of the water transfer pipe 1, for receiving the connection screw 3.
  • the diameter of the first end 31 of the connection screw 3 is larger than the diameter of the aperture 13.
  • connection screw 3 is receivable in the aperture 13 from the inside of the water transfer pipe 1.
  • the outlet pipe 2 is connectable to the transfer pipe 1 by virtue of the corresponding screw threads of the second end 22 of the outlet pipe 2 and the connection screw 3.
  • the fact that the connection screw 3 is substantially hollow means that the connection screw include an inner conduit for transferring water from the transfer pipe 1 to the outlet pipe 2.
  • the transfer pipe 1 and the outlet pipe 2 are further connected together by virtue of a connection formation.
  • Each of the second end 22 of the outlet pipe 2 and an outer surface of the transfer pipe 1 includes a pair of fixing holes 41.
  • the connection formation also includes a pair of fixing pins 4 which are receivable in the openings 41 of the transfer pipe 1, and the outlet pipe 2, so as to hold the transfer pipe 1 and the outlet pipe 2 together more securely than if the connection screw 3 is used alone.
  • a water sealing ring 23 is installed at the second end 22 of the outlet pipe 2 in the preferential option, with which better sealing can be achieved after connecting the water transfer pipe 1 and outlet pipe 2.
  • connection screw 3 In order to connect the parts of the tap 10 together for use, the substantially hollow connection screw 3 is inserted into the opening 14 via the in use upper end of the water transfer pipe 1.
  • the connection screw 3 is able to pass through the opening 14 to enable the second end 32 of the connection screw 3 to extend through the aperture 13 in the wall of the water transfer pipe 1.
  • the first end 31 of the connection screw 3 is larger than the diameter of the aperture 13, and therefore the connection screw 3 cannot pass out of the water transfer pipe 1 via the aperture 13.
  • connection screw The threaded outer surface of the connection screw is connected to the internally threaded second end 22 of the outlet pipe 2. Then an Allen key is inserted into the opening 14 of the water transfer pipe 1 from the in use upper end. An end of the Allen key is inserted into the opening of the connection screw 3 and engaged therewith, such that turning the Allen key, turns the connection screw 3 and firmly connects the connection screw 3 with the outlet pipe 2. Turning the Allen key repeatedly tightens the hollow connection screw 3 relative to the outlet pipe 2, until the water transfer pipe 1 and the outlet pipe 2 are firmly connected.
  • fixing pins 4 are used to affix the water transfer pipe 1 and the outlet pipe 2, so that when the Allen key is turned, the water transfer pipe 1 and outlet pipe 2 will not be turned relative to one another, which is better for attachment.
