Lesson fifteen: water tanks in your Benimar

This article explains how to fill your fresh water tank and how to empty your grey water tank

Fresh Water Tank Instructions

To fill your fresh-water tank:

  • There is a flap on the outside of your motorhome.


  • Lift the flap and you will see a blue water cap.
  • To open the cap, you push it in and turn (cap lock must be in an unlocked position).
  • Pop in your hose and fill it up.
  • When it's full, water will back-splash back from the inlet.
  • Replace the blue cap by again pushing in and turning. You can lock this cap if you wish.  


Please Note:

  • Empty the water from the fresh-water tank if you are not using it for a while. 
  • To do this you roll under the motorhome driver’s side and you will see a blue tap – turn the handle anti-clockwise to dump the water from your freshwater tank – see photo below of what it looks like:

Greywater Tank Instructions 

To empty your grey water tank:

  • Locate the brown hose from the plastic container in your boot or locker.
  • Locate the greywater outlet on the outside of your motorhome.
  • See below video clip of what it looks like and how to attach the hose and open the outlet: 

Please Note:

  • Always empty your grey water after your travels or whenever you can. 
  • Please only empty your grey water at dedicated grey water dumping stations. 
  • Ensure you rinse the brown hose after you have emptied the tank and keep it in the plastic container. 
  • To ensure your grey tank does not start smelling, be careful what goes down your sink drain. Wipe down greasy plates with a paper towel then wash them and don't let food waste go down the sink.
