💧 Water leaking under the camper and cold protection valve - Camper Castle (Knaus Sky Wave)

If water leaks from under the vehicle, this can have various causes:

  • Please check whether the levers of the two tanks are closed.
  • It may be that the cold protection valve is open. It is located behind the service flap, next to the fresh water tank:

The cold protection (or anti freeze) valve automatically drains the boiler when there is a risk of frost. This prevents the drain from freezing. 

The system measures the temperature inside the van. As soon as it is around 3 degrees or lower the system is activated and lets all the water that was in the boiler and the fresh water tank out. To deactivate the system, the room temperature has to be a least 7 degrees, otherwise the blue button will jump out again.

To ensure that the water supply continues to function and the valve is switched on, the blue lever must be turned clockwise and then the blue button must be pressed in.

Only a few litres remain in the tank and everything else flows out?

There is a rather hidden setting to keep just a 20-litre fill for light driving.

  • Open the service box and unscrew the large red cap of the fresh water tank (the tank should be quite empty!).
  • Find this blue rod inside, push it upwards until it clicks into place – then only 20 litres will remain in the tank.
  • Pull it down to be able to fill the tank completely again.
