Oslo Support: Water Leakage Under the Vehicle

Modified on Fri, 20 Sep at 3:27 PM

If you notice water leaking from your vehicle, you should first check whether both the fresh water and grey water tanks are properly closed and whether the frost guard may have been triggered.


To check the fresh water tank, open the small cabinet between the sink and bed, directly at floor level. Remove the cover on the floor and look for the red lever underneath. Ensure that it is in the closed position. Also, check the nearby valve to ensure it is also closed.


The grey water tank is located on the outside of the vehicle on the driver's side. You should check whether the tank is properly sealed.

If water continues to leak, the frost guard might have been triggered. This mechanism protects the water system from freezing damage in cold temperatures. The frost guard can be found under the rear seat, opposite the kitchen area. To reset it, turn the blue wheel 90 degrees until it clicks into place, and press the blue button at the bottom of the device. This will close the water lines and make the system operational again.
