I have put a 55 litre water tank in the back of my dual cab, and was looking for a small in line pump to out provide the water a bit quicker than gravity. Is anyone aware of s amll pump to do the job which doesnt cost a small fortune

Hi VCBB

There are heaps of pumps around that will suit your purpose. I have a Johnson on my camping trailer for about 3 years and has never missed a beat. Cost was arount $100. Got it from a fishing tackle shop.
Would imagine there would be some on EBay also.
Good Luck

Flojet or similar would be the go.

My vote goes with the Whale, amazingly reliable and robust. I use one for my football field line marker when the expensive one breaks down and for quick jobs. Been going 3 years now and sits unused in the 6 month off season every year.

I know people who've used teh Whale pumps and been really happy. $50 from Whitworths (boat shop):


Wouldn't discount gravity. I've always used it for water. My current 75litre undertray tank has 1/2 inch hoses and fittings and a high flow tap (like rainwater tank tap) that is mounted on the back of my cab, just below the tank, and flow is very good.

Beware the Whale.
I have one in my setup and they will allow flow withot power.
My outlet is above tank level, but given a fairly full tank and a steep incline it can drain (even if only partly) through the pump.
I installed a 24vAC irrigation solenoid valve (Yes, to my surprise it does work) wired into the same switch as the pump and this has solved the problem.
I have had mine for 4-5 years without trouble and as others have said, they take up little space.
Given the option I'd go for gravity.

Do you have to prime the Whale Pumps , or self priming like the Flojets etc ?

I personally like the flojet pumps for this type of thing

The Whale is the go. Cheap, effective and takes up bugger all space. Use one of those push to operate type of switches so that you don't waste water. Can get them at SuperCheap for a few dollars.

Go to Bias Boating Superstores. They're a chain store with very good prices.

I use a Jabsco which is as powerful as the mains and cost about $130 from memory.

Yes as Roachie has posted Flojet, No 1 reason is that they are not cheap Chinese crap , and if you don't mind me asking , what type of water tank did you get, I have an 80ltr under the bed in my Troopie . like this one but inverted.

And that of course is the problem with electric pumps versus a gravity or hand pump when using precious fluids - they can be wasted.

You're dead right there. When I was setting up my set-up I quickly discovered that I need an in-line tap at the point of use as after turning the pump off syphon gravity took over withwater continuing to flow.

Rod,

Being an old offshore racing yachtsmen, it is notable that very few boats have electric pressure pumps for water supply but use manual types.

The reasons for this I suppose are two fold in that race yachts don't carry that much water in the first place so its pretty precious stuff and hand pumped water is less wasted and of course the other is as you describe with syphoning a real threat on tipping and rocking boats.
