I designed and built a twin auto-changeover Aquaroll system on our last van over 20 years ago. That caravan was sold about 18 years ago and we only bought our next caravan in 2019 to return to the hobby/pastime. Our new van is a 2019 Swift Elegance with all kinds of clever controls and water supply options so I assumed that building a new changeover system wouldn't be necessary. On our first trip I changed my mind. Yes we could fill the inboard tank and get an alert if it needed refilling, but I found the onboard pump noisy and I didn't warm to its pulsing delivery. There was also the need to drain the inboard tank of surplus water before leaving site . The second option of drawing water direct from an aquaroll still used the same pump and limited the volume available. I will post pictures if any interest, but my system is as follows: 2 Aquarolls with 2 Truma submersible pumps fitted to 2 Truma Compact inlets on the side of the caravan. The Aquarolls have float switches fitted into them and low voltage electrical connectors/cables entering the van by the water inlets. Function: Fill both Aquarolls, fit both pumps and connect cables. Inside van is a control panel which shows a Blue LED for each Aquaroll to show if they have water in them. Whichever Aquaroll is connected first also has a red LED showing it is selected. Use the taps/shower as normal. When the first Aquaroll is empty, the water supply is automatically switched to the other full one (if showering for example only a momentary splutter is felt during the changeover). The control panel now shows the second Aquaroll is selected and the first Aquaroll's blue LED goes out showing it needs filling. The exterior pumps are nice and quiet in the van. Just keep refilling the identified empty Aquaroll at your leisure for a constant water supply. If using a serviced pitch just connect the one Aquaroll - it just never empties so is never switched out. The original swift system is still selectable for Arctic trips and caravan warranty purposes. As I indicated, will post pictures if any interest, otherwise will carry on with other mods (Eg: thermostatic shower, shower extractor fan, A/C install, new sound system, etc, etc).
