Setting up a 12V water system in a solar cabin

You have found your cabin in the bush and now you want some little luxuries like running water! Here are some options for you.

If you only have a single tap then you need the FL2202 which will supply enough water for one tap at just under standard household pressure. You can even add another tap if you are happy to use them one at a time. If you want to be able to use the two taps at the same time then the Jabsco Par Max 1 will be the best pump for you.

A less basic cabin set-up may have 2 taps, a shower and a toilet.  Each of these outlets have different requirements for pressure and amount of water. For instance, you don’t want your shower to run as slowly and at low pressure like the toilet cistern tap!

The variation in demand means that you have two choices – install a pump which has a single output – 12.5lpm @ 35PSI (FL35) plus a pressure tank. The tank holds a reserve of pressurised water in a bladder to be used each time you turn on the tap. Once the bladder is 2/3 empty the pump will kick in and replenish the water in the tank.

This allows non-smart pump to service a range of outlets with different needs.

Or you can install a smart pump such as a Jabsco or Shurflo pump, which will match the required pressure and flow of your taps – no need for a pressure tank. While the pump is more expensive the saving on the pressure tank usually means you are already ahead. And the smart pumps often come with a 3 year warranty.

To select the best pump you will need to find out the following information:

  • The PSI and flow required by your HWS
  • Number of taps in your house
  • Distance and height from the water tank to the pump
  • Distance and height from the pump to the furthest tap.


HWS 35PSI and 10 lpm

2 taps, 1 toilet, 1 shower

1.5m to pump

4 m to last outlet.

Recommended options:

FL35 pump (RRP$99) + Accumulator tank (RRP$167),

or Jabsco ParMax 2.9 (RRP $169.50) or

Shurflo Fresh 3 (RRP$249).

 If you want to add in extra taps later then you might be wise to err on the side of being generous so that you will have enough capacity.  Each of the above pumps has a model up with a little extra flow – FL40, Jabsco Par Max 3.5, Shurflo Fresh 4.
