I am thinking of getting some sort of 12V water pump, to pump water from a creek or tank into my caravan tanks when required. Naturally I would only be using good quality water sources and the source would have to be filtered somehow.
I have
battery power to stay somewhere for about a week, but only enough water in van to stay for about 4 days, maybe 5, hence the need to get water into van.
Was thinking that as I already have all the hoses etc in my van anyway, this might be a better idea than carrying a couple of 20 litre plastic water containers that would only get used infrequently.
Was thinking of a shureflow similar to whats in my caravan, but cant seem to find any specs on it. I want to be able to pump from no more than say 10 metres distance and then up about 1 metre into the vans water fillers. The height of a river or creek bank would probaly have some effect on the ability of the pump to do the job as
well i would imagine.
Does anyone know if this idea is feasable and if so, are there any suggestions as to what brand/model of pump would do the job.
Thanks
Cruiser

Bilge pumps used in boats are good to use

Thanks, but will they pump over that distance and height without having to buy something that will break the bank or be suitable for the QE2

Yes, easily.
They come in a range from 550 gallons per hour (gph) to
well over 2500gph for less than $175. This rating is calculated over a lift height of normally 2m. If they need to lift higher then this figure will come down (obviously) but they do produce a fair squirt of water so just find your flow rate then go to a chandelery and talk to the guys in there (just avoid
places like BCF, they know absolutely nothing about thier products, a smaller store is often the go but you pay a premium for the service and knowledge).
Most have a clip on protector to stop crap getting into the impellor housing and are incredibly reliable. Have two 550 gph 12v pumps in my fish tanks that have continually run for almost four years without a problem, would get the brand for you but they are buried right in the bottom of it and coral dont like being moved.
When you make the connections for your power supply, be sure to make them waterproof (either vulcanising them or find a waterproof connection holder) as though the pumps are completely sealed on the outside, water can still force its way through the gaps between wire strands and plastic sheath of the cable into the pump.
Have fun :)

Hi Cruiser.
I use a flojet pump(originally a bilge pump!) for my shower system.It can pump from a drum or direct from a creek. Sorry I can't tell you the flow rate. I have seen similiar pumps on ebay with various flow rates.

Hi
Second that place, buy a lot from there. Have a look for non return valves, the one I use is the little one that fits in the hose, the advantage to it is if the pull is a bit higher you can prime the pump from a bucket then walk down to the river. They also have non return valves with filter ( bilge area ). I have a large pond filter on the end of
mine and it works a treat.
Have fun

Hi
Forgot these pumps hate grit so you need a good filter near the pump have a look at the one on this unit Site Link if you got one of these pumps you could wash your rig at the same time, I have this one and use it for lots of things as
well as the shower, kids reckon it hurts them.
Have fun

I don't want to sound like a Luddite, but have you considered a bucket and a funnel? At least then you can see what you are getting. With a pump you have to make sure that the hose doesn’t drop into the sediment on the bottom, can push water to the height you want (the higher, the slower it is) and that the pump can prime it’s self at the height it is at, as you don’t want to stuff around with foot valves. Then there is the setup and knock down time.
Get the pump for the shower, but sometimes for moving water a bucket is easier and less trouble.
The Flowjet and Sureflow diaphragm pumps are great though, much more versatile and reliable than a bilge pump. If you have the time to rig up a pressure tank and a pressure switch they are like having mains pressure camping and the pump doesn’t have to run all the time if you only need low flow.

G'day hoyks
I totally agree. 2 plastic buckets, a,funnel, a willing wife who needs a shower, a can of VB & a can of Beam, and a spare 15 minutes can deliver all the water you need for a couple of days.
The Kiss principle works for us.
Also if the water is a bit cloudy leave it in the buckets for a couple of hours whilst the silt settles so that you can qualify for a can of beer in similar timing.

I've used the pump from my Jaycar 12v shower to fill jerries from a
bore hole (water only about a metre down). Just removed the shower head. Worked fine, took only a few minutes per jerry, and beat dropping billies on a string down the
bore casing.

Cruiser,
We use a submersible pump of reasonable quality (cost about $139.00) to lift water from creeks. They have more tolerance to grit and algae than diaphram pumps and can pump at a good rate. They are also easy enough to clean. I tie a chux cloth around the intake just to give extra protection against "floaties".
This pump is similar to those that you may have seen in those 12V shower kits, only it is more rugged and able to deliver more water. It is a lot quieter than a diaphram pump and uses less electricity. They have a simple bearing assembly and when they wear out you have to throw the entire pump away, but they have a reasonably long life.
We then use a diaphram pump to push that water through a reverse osmosis setup to make the water drinkable.
Cheers,
Russ.

Bias Boating has a 12V, 11 litre per minute pump on special at the moment for $99.90.
Details: Jabsco Par-Max 2.9 12V Pressure Pump, Cat. 5054JX, BIAS Price $99.90
It is a special listed on their
home page. Not sure what head of pressure it is rated to but for the situation you describe, I believe it will handle the job admirably.
Alternatively you could buy a couple of Y-Valves ("Plastic 'Y' valve for hose ID 25 or 38mm, part # 1233X and 1234X respectivley, price $29.90) and use your existing van pump to fill your
water tank. Switch the valves so inlet is external and not tank and outlet is tank and not tap.
Regards
David

Grungle,
I like the sound of the Y Valves. I must admit that I had not concidered that possibility.
Thanks, I will look into that idea.

Cruiser,
Try a whale brand inline submersible pump from whitworths, can pump water,fuel and other products with good flow and will pump a good head. (up the creek bank) It has 1/2 tails each end of the pump. Have known people who drop them into 44's of Diesel for transfer.
