Selecting the right 12 volt water pump for your caravan, bus or cabin in the bush is as simple as getting a 12V water pump that will service the number of taps (outlets) you have. EG: Toilet, shower, bathroom sink and kitchen sink = 4 outlets
For the budget conscious with 4 outlets the Escaping Outdoors 12V FL40 is a great choice. A great diaphragm water pump for caravans, best used in conjunction with an accumulator tank. The 24V model often used in buses is the FL44.
The Jabsco 12 volt Parmax 4.3 is equivent to the FL40 in output and has the addition of a built in bypass within the pump which means you rarely require a pressure tank with this caravan pump. Also available in 24V.
The Shurflo 4.0 and Shurflo 5.0 fresh water pumps are available in both 12V & 24V models. The addition of a built in mechanical by-pass function enables these pumps to vary their flow rate for any on-demand condition, including low flow, without cycling and without the need for an accumulater. A brilliant quiet caravan pump!
