Motorhomes, being self-contained vehicles, have onboard tanks to hold a fresh water supply. Generally, the tank will contain between 80 and 120 liters of water, although some may have tanks that will hold up to 200 liters.
Motorhome users carry
their own food-grade water hose. The connection in general use across Europe is the common 3/4" BSP threaded outdoor tap connection.
A push tap is best for the application as it eliminates any incidence of water wastage due to a lever or spindle tap
being left in the on position.
