Arriving on site: Motorhome Water System
Understanding the Water System
Your motorhome has two main water tanks.
- The freshwater tank stores clean water for use inside the motorhome. This supplies the taps, shower, and toilet.
- The wastewater tank, often called the greywater tank, collects used water from the sink and shower.
Both tanks are mounted beneath the motorhome.
Water is delivered to the taps by an electric pump, which is controlled from the habitation control panel.
Filling the Fresh Water Tank
Using the Whale Aquasource hook-up
- Locate the water inlet socket on the outside of your motorhome
- Connect the Whale Aquasource plug. It should click into place
- Attach the other end of the hose to the campsite water tap
- The pressure regulator fits between the tap and the hose. This regulates the incoming water pressure
- Turn on the campsite water supply
- Water will flow through the Aquasource hose and into the motorhome’s fresh-water tank
- Inside the motorhome, you can monitor the tank level using the control panel display. As the tank fills, the indicator will show the increasing water level
- Some systems will provide a visual indication — and sometimes an audible alert — when the tank reaches full capacity
- Once the tank is full, turn off the campsite tap and pack away the hose
Using an Aquaroll or Portable Water Container
- If you don’t want to move your motorhome, you can fill the tank using a portable water container such as an Aquaroll
- Place the container near the motorhome and use a dedicated pump to move water from the container into the onboard tank
- Lower the pump into the container and connect the hose to the external water inlet
- Switch on the pump and allow the tank to fill
- Again, you can monitor the water level on the control panel display, and the system will indicate when the tank is approaching full
- Once the tank is filled, switch off the pump and disconnect the hose
Activating the Water System
Once the tank is filled, you can activate the water system in the motorhome.
- First, check that the drain down switch is closed and ensure the 12-volt system is switched on at the control panel
- Next, switch on the water pump using the pump control button
- The pump may run briefly as it pressurises the system
- Open the hot tap in the kitchen. Once the water heater has filled and water flows freely, gently open the cold tap
- Open the other taps, including the shower
The system will now supply water to:
- The kitchen sink
- The washroom basin
- The shower
- And the toilet flush system
Monitoring Water Levels
The control panel allows you to monitor both the fresh-water tank level and the waste-water tank level.
This helps you keep track of how much water you have available and when the waste tank needs to be emptied.
Tank readings may fluctuate slightly if the motorhome is parked on uneven ground, which is normal.
Calibrating the Water Tank Sensors
From time to time, the tank level sensors may need recalibrating to maintain accurate readings.
- To do this, start with an empty fresh water tank
- Then go to the control panel settings and calibrate the tank as empty
- Next, fill the tank. You may have to check the fill level via the access cap to make sure it doesn’t overflow
- Once the tank is full, return to the control panel and calibrate the tank as full
- This allows the system to measure water levels correctly between empty and full
The wastewater tank is calibrated in the same way.
Using Water in the Motorhome
When the pump is switched on, water will flow automatically whenever a tap or shower is opened.
Hot water is supplied by the motorhome’s heating and hot-water system, whether you have a Truma or Alde system.
Emptying the Waste-Water Tank
The wastewater tank collects used water from the sink and shower.
- When it becomes full, it should be emptied at a designated motorhome service point on the campsite
- Position the motorhome over the drain point and open the waste-water valve located beneath the vehicle
- Allow the tank to drain completely, then close the valve before leaving the service point
Emptying the Fresh Water Tank
Locate the freshwater drain valve under the vehicle and open it to allow the tank to empty.
Helpful Tips
- Always use clean drinking-water hoses for filling the tank
- Empty waste water only at designated disposal points
- Keep an eye on tank levels using the control panel display
