Frequently Asked Questions - Water Pumps

Setting up a 12V water pump system in a solar cabin or shed

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

12V pump choice for a single tap outlet

If you only have a single tap then you need the FL2202 12V pump 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. 

12V water pump choice for a cabin with 2 taps

A less basic cabin set-up may have 2 taps, a toilet and a shower.  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 – 12.5 L/min @ 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" 12V water pumps to service a range of outlets with different needs.

Or you can install a 12V "smart" water 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 "smart" water pump is more expensive you dont usually require a pressure tank as this ability is built into the smart water pumps. Smart pumps often come with a 3 year warranty. On the downside if the Smart Pump does have pressure switch failure your set-up is telling you that you require a pressure tank and a new pressure switch. 

How to select the 12V pump best suited to your needs

To select the best 12V 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.

Example:

HWS 35PSI and 10 L/min

2 taps, 1 toilet, 1 shower

1.5m to pump

4 m to last outlet.

Recommended options:

FL35 pump + Accumulator tank 

or Jabsco ParMax 2.9 or Shurflo Fresh 3

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 – Escaping Outdoors FL40  used with an accumulator tank for 4 outlets, Jabsco Par Max 3.5 delivers 13.2 L/min to 3 outlets or the Jabsco Parmax 4.3 delivers 16.3 L/min for 4 outlets or the Shurflo Fresh 4 delivers 15 L/min to up to 4 outlets as examples.
