  • the first tubing 27 is arranged inside the second tubing 30 is maintained in the second groove 42 and locked by the locking part 43. This is also shown in the side view of the leak-safe water tap system 100 shown in Fig. 19 .
  • connection box 2 ensures that the first pipe 3 is sealingly connected with the water supply 26. This may be provided via the connection box 2 itself, via a connection part 21 arranged in connection with the connection box 2 or via an interface part also being in connection with the connection box 2.
  • the water supply 26 comprises a first tubing 27 having a first tube end connected with the connection box 2 via the connection part 21 and a second tube end connected with the water supply 26.
  • the system 100 also comprises a second tubing 30, the second tubing 30 has an inner tube diameter being larger than an outer tube diameter of the first tubing 27 like in same manner as shown in Fig. 2a in relation to the first pipe and second pipe.
  • the second tubing 30 has a first tubing end being in a leak-tight manner connected with the connection box 2, the second tubing 30 having a tubing extension extending from the first tubing end 31 towards a second tubing end, wherein the second tubing 30 circumferences the first tubing 27 at least along a tubing part of the first tubing 27 arranged within the wall for ensuring that any leak of water will not leak into the wall.

  • the present invention according to the third embodiment ensures this possibility. This may be performed by unscrewing the locking screw 20 so that the first pipe 3 is freely movable. By pulling the tap 4 with a force higher than the force for maintaining the snap-click connection 24 in position it is possible to pull the first pipe 3, the connection part 21 and the first tubing 27 out through the second pipe 9 as shown in Fig. 21b . Obviously, the first tubing 27 has been released from the water supply in the opposite end in relation to the connection part 21. Also, the first tubing 27 is made of a flexible material, such as a polymeric material.
  • first tubing 27 When the first tubing 27 has been completely removed a new first tubing may be guided in through the opposite direction meaning that the first tubing may be introduced via the second pipe 9 and therefrom into the second tubing 30.

  • This third embodiment is a flexible system which both provide the possibility of changing a first tubing 27 while providing a leak-safe water tap system 100.
  • first pipe, the second pipe, the first tubing or the second tubing may be made of a rigid material such as metal or composite, or the first pipe, the second pipe, the first tubing or the second tubing may be made of a polymeric material.
  • at least the first tubing is made of a flexible material such as a polymeric material.
  • connection part is made of a rigid material such as metal especially when it has an internal thread.
  • connection box may be substantially square-shaped and may have a height of between 60 mm to 100 mm and a width of between 40 mm to 70 mm.
  • the inner diameter of the second pipe may be between 25 mm to 40 mm.
  • the outer diameter of the first pipe may be between 20 mm to 35 mm.
  • the second pipe may have an aperture near the second pipe end 11 and outside the wall for allowing potential leaked water to escape out of the second pipe without entering into the wall.
  • the plate member may have a leaking groove extending from the aperture and downwards so that leaked water in the second pipe may flow out of the second pipe and into the leaking groove defined by the plate member and the exterior wall.
  • the second pipe is sealed off at the first pipe end 10 in relation to the connection box 2 so that any leaked water from the first pipe only will leak into the second pipe and therefrom flow towards the second pipe end 11.
  • the present invention also relates to a building having a wall wherein a leak-safe water tap system as described above is arranged.
