Hands-free motorhome water tank filling
The Rheinland and Portland motorhome water filler caps fit most UK and European motorhomes. Please look at the product images to confirm which one fits your camper.
The Rhineland and Portland water filling caps fit in place of your locking water cap during filling. Connect your hose to the standard hose connector and easily refill your fresh water tanks without someone else holding the hose in place.
- The large Rhineland filler cap fits 8cm diameter inlets, to suit 55mm water inlet
- The small Portland filler cap fits 6.6cm diameter inlets, to suit 48mm water inlet
- Nether fit the Fiamma 2 bayonet filler cap
- See product photos for correct identification
Portland water filler caps probably fit the following brands: Arca - Chausson - Caravelair - Challenger - Silver - Streckeman - Benimar - Autostar - Vendome - Sublim - Fleurette - Dethleffs - LMC - TEC - Solifer - Polar. Most other brands will require a Rhineland filler cap.
How do I know when the tank is full?
These water caps fit securely onto your water tank filler point but, have pressure release systems that allow air and water to flow around the cap. You will probably hear burbling as your water tank gets close to full, in the same way that happens when fueling up. Once the tank is full water will leak out around the cap.
Heos water filler cap hose connectors are twice the price and do the same job.
