Submersible water pumps
In most caravans, submersible water pumps ensure that the water flows. These pumps are simply suspended in the water tank and, with a 12 V motor, they pump the water from the tank to the points of consumption. When you open a tap in your caravan, a microswitch starts the pump.
Advantages
Easy to install as the pump is suspended directly in the water tank Very few breakdowns caused by small dirt particles in the water Runs quietly Relatively inexpensive Won’t freeze if the water tank is emptied in good time
