Hi all.

Need some advice on water filters for a camper trailer that I am finishing off.
I have a 12v flow pump 35psi and 12.5lpm.
I have been to two different places today and had two different answers.
1 was the pump won’t work because it won’t be able to pump the water through the filter.
2 will work fine just less pressure.
I have two taps, I will be for filtered drinking water and the other will be for washing up.
Could I please have some suggestions on what others are using as I am now confused
I would like to try and filter out as may nasties as possible.
The other option I had was a filter jug but that is just another thing I have to cart around.


Thanks in advance Pat

I would have thought that at 35psi you would get plenty of flow through the filter. If it's just for drinking purposes if the flow is a bit slow it wouldn't matter.

I use a filter on my van but it has a pressure pump and the filter really doesn't make any difference to the flow.

depends on the filter
the lower the micron number the higher the resistance

10 micron ..i dont think you'll get too much water at all when it giets a little dirty

100/200 micron...may be the go...

try to get onto a manufacturer of the filters for better advice...a name escapes at the moment

to ensure low health risks maybe better cost to take bottled (cask) water for drinking and use the camper trailer water for cooking (heat kill bugs) and washing

a 2.5" x 10" (Length) .5 micron you can expect around 8 psi pressure drop at a 2 GPM (US gallons)

try here for further info to help make up your mind ....look for info coarser filters

may be 100 micron might not be the go...try 50?

Hello Pat,
You have to decide what quality water you want.
If you want the very best (rainwater or distilled water quality)then you have to go for a Reverse Osmosis Unit – this produces the purest water. Common ones used in houses run at high pressure (around 50/60 PSI). They are not cheap and I paid $400 for one a few years ago.
You may be able to buy low pressure models - have a search on the net.
Filter units are much cheaper, and do not need high pressure but will only remove the heavier sediment and will not remove minerals.

Pat,

the pump you have should do the trick. I operate a dual filter water system with a prefilter then a .05 micron cannister (removes gardia and even tanin colouring from water). It's slow with a .05 but does a great job. I use the sureflo pump that goes with the twine shower under the bonnet so it's actually pushing the water through the heat exchanger as well.

Cheers,

Mick.

A neat filter for a camper is the BEST filter they come in I think 5 micron and 0.5 micron and also have activated carbon and silver to kill the bacteria they can be reversed to flush out etc.

I put one on my camper (0.5 micron) with a Surflo pump and is a bit slower but runs the shower etc and now saves a bit of water.

Takes out a lot of the bad taste
