💧 Fresh water and waste water / grey water - Cozy Cottage (Knaus VAN TI PLUS)

Fresh water

The fresh water tank (100 L) is located on the driver's side and supplies the sink, toilet, and indoor/outdoor shower. To open it, you need the medium-sized key. Open the flap and look for the blue cap:

The refilling of the fresh water tank works with a canister with an attachment or with a hose. Please ensure that both the fresh water and waste water tanks are closed. They might still be open from the previous rental.
To empty/open or close the fresh water tank, operate the lever next to the blue sticker:

Note: Fresh water is not drinking water!

Waste water

The waste water tank (73 L) is also located in the service box on the driver's side. To empty it, set the lever next to the grey sticker horizontally.

Watch the video:

You can see the levels of the fresh and waste water tanks on the control unit (display varies depending on the model):

Troubleshooting

Water leaking under the vehicle

If water is leaking under the vehicle, this can have various causes:

  • Please check if the levers of both tanks are closed.
  • It might be that the frost protection valve is open. It is also located in the service box on the driver's side - far right:

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.

  • Boiler valves accidentally open? 
    These can be found in different places depending on the model:
VW 
  • There are two of them. You can find them in the lowest kitchen cupboard, under a cover. Turn them clockwise to close them:
MAN or Fiat Ducato
  • There are two of them. You can find them in the cupboard next to the bathroom:

  • Remove the plastic cover to expose the valves. Turn them clockwise to close them:

No water flowing

If you turn on the tap but no water flows, this can have several reasons:

  • First, check the level on the control unit to see if the fresh water tank is sufficiently filled.

    There should be at least 20 litres of water in the fresh water tank so that the pump is completely covered and filled with water, allowing it to automatically unlock after running dry!

  • Check if the water pump is switched on at the camper display (display varies depending on the model): 
  • The fuse of the water pump might be damaged.

Before any fuse is pulled, following safety measures is required:

  1. Turn off the engine and remove the key from the contact.
  2. Unplug the car from any external power supply.
  3. Pull carefully on the fuse by pulling from the sides.
  4. A damaged fuse can be burnt or have the connector broken (see picture). If so, please replace it. You can find them at petrol stations and hardware stores. 
  • The fuse box is located on the driver's side in the boot. Check and replace this 10A fuse (fourth from the left):

Only one of two water taps is working?

If the water pump does not activate when you turn on the tap, the micro-switch on the tap lever is probably defective.

To still put the water pump in the ready state, follow these steps:

  1. Test the other tap (e.g. kitchen or bathroom).
  2. If another tap works, open it just a little so that you can hear the water pump, but no water flows.
  3. Now open the tap with the defective micro switch. The water should now run.

Attention: Don't forget to close both taps completely afterwards!
