G'day all

The dried arrangement would like a water pump in the van.

I'm browsing the net and notice that there is a wide range of pumps and pressure.

I figure that 35-40 psi would be sufficient.

Am I on the right track?

That seems about it.....our Flojet is around 35psi and 12L/m*.uses pressure switching...once turned on, it simply responds to tap usage. *installations are unique though...
factors will vary and the pressure switch will probably need a tune.

Boo Boo,

Leaving the "dried arrangement" comment well alone...lol, try the websites for Flojet, as has been mentioned and also Shurflo. These guys make a variety of pumps driven from various voltages including 12v. There is a pretty broad selection of volumes and pressures to suit a wide variety of applications. Some even come with viton components to handle less than perfect fluids.
35-40 PSI should be all you would need if just for showers, toilet and kitchen supplies.

Thanks fellas

Looks like it will be a flojet or shurflo at around 35psi. It's only needed for the tap over the sink.

We are in Wagga for the next 5 weeks and noticed there is a "home and life style " show in Albury this weekend so we are going to have a look tomorrow as caravans etc are part of the show.

Might see something we like. lol

If there is a dealer for agricultural spraying equipment in Wagga have a wander in there as well. Those pumps get used where relatively small volumes of fluid need to be delivered. May be a better price than the show you mentioned. Not sure but maybe worth a look.

Well, we went to the show and I bought a seaflo pump.

35psi and 4.1 lpm. More than enough for the sink.

Oh, it also came with a tap. Total cost $65.

can't recall the brand, but have had 2 of the same type inline 12v pump(switch on/off type) fitted with a flow back stop valve. Extremely small too, but with more than enuf flow for the kitchen sink. One was fitted down by the tank and the other already came fitted right up near existing pump tap. both operate well as does the hand pump still. Has gone dry once only but unscrew plunger pour water down, replace and off it went again. Satisfies my "dried arrangement"perfectly.

Kevmac

You might be able to help me with this question.

If I fit it to the existing tap will I have a problem when the caravan is hooked up to the mains pressure at a caravan park, or does the water pump need to be on the hand pump tap?

Please note I am going to replace the hand pump with one of those plastic camec taps if its not a good idea to hook the pump onto the mains tap.

As I'm writing this I think I can see that it's probably a bad idea to hook it up to the mains tap. Guess I'll go to an irrigation centre to get a reduction connector as the tubing on the hand tap is larger than the inlet/outlet on the pump.

you hook it up in the existing hand pump line from your tank, usually as close to the tank as possible. I cut the handpump line, installed the anti flowback valve& then the pump. Then pick up your 12 volt feed from wherever and wire that in via a switch(pushbutton is best). Don't forget to physically secure the pump of course.
