Gday All

Just put a Twine under the bonnet. Only used in the backyard (till Easter) so far but am very happy.

Question: I want to pull water from a river where I am camping, How long a hose will the pump (larger model fitted) pull water through? and has anyone come up with an easy/smart way to do this and filter the inlet side other than the filter that comes standard in-line?

Any help appreciated.

I've found that distance, as such, isn't really the issue. It's the "head" (how far you are raising the water) that counts. With the 12lpm pump, I've drawn about 8 logitudinal metres, and about 1.5 metre head. You might need to prime the pump a little first (fill the hose with water and tip it back towards the pump) before you get going - even though the SureFlow and FlowJet pumps clain not to require priming. Run them too long without water and it shortens their life IMHO.

You're right about priming I reckon. I don't require a high 'head" as i always have water supply at road level. However, I have had issues with the pump not wanting to self-prime which has led me to fit a small rubber bulb (from outboard motor) to the intake end of the hose. This stays on there and sits in the plastic box which I fill with water. A couple of squeezes gets it primed and pumping ; no worries.

G'day John,

Don't have a twine but do like to pump from a creek or river. Use a filter made by the people that make the sand spear about the size of half a toilet roll (cardboard section only). It fits on the uptake end of the filler hose and is made from SS (there is some micron filtering capacity but have long forgotten this). Its main purpose (as you can imagine) is to stop sand like bits and will get clogged by leaves and mud.

Kind regards

I dont know what Filter comes as standard but I use a simple inline Garden filter. cheap and does the trick for me.

I've only seen it once , but I saw a guy pump from a river , with a Balloon tied to the hose , so it wouldn't drag in the mud.

Seemed to work.

I got a nice in-line filter from Whitworths boat supplies which is bigger than the standard Twine filter plus the body is clear plastic so you can see if it's getting blocked up. I think I read somewhere that the pump you are talking about which is the same one I have will draw up to a head of about 6 feet. As long as you are using a reasonable internal diameter tube, the horizontal distance it is drawing shouldn't make much difference at all, as the only work the pump has to do is to overcome friction of water with the sidewall of the tube.
Other than a long tube, I can't offer any great pearls, but I did also get a 100litre water bladder also from Whitworths. I drive down to the river, connect an inlet tube with the filter to the heat exchanger inlet and put the filter in the river. I connect the outlet of the pump to another hose which feeds to the bladder. Turn on the pump with the vehicle idling (charging the aux battery) and the pump sucks up river water, (optionally partially heats it if I want) and fills the bladder to about 90litres. The when I connect the bladder to the inlet of the exchanger, I've got 90 litres on tap.
I'd rather be able to draw continuously from the river though.

Hello Team,
This is a theory I've had for years and never actually tried it. My mate the pump guru says it will work, though he says its not a pump unless it's a metre in diameter.
Also, my heat exchanger is home made, 3" stainless tube, hand wound copper coil etc. Mate and I made 6 or 8 back before the Glind was a Glint in someones eye and when Twine was something my grandmother tied a brown paper parcel with.

Onto the idea, Get yourself a boaties bilge pump, submersible type. Approximately the same or very slightly higher flow rate than the shower pump.
Toss it in the river and use it as a lift pump in the same hose as the shower pump, it'll prime the shower pump.
Alternatively, use the bilge pump to fill some sort of drum and then use the shower pump to draw off the drum.
According to my mate the pump guru, will work best if the bilge pump has a higher peak flow than the shower pump.

Hope this helps,

John ,

An interesting post for me , as like you , I have had Twine installed by ARB but have a few questions before I use it . I tried to control the temperature by changing the heater settings , but it made only a small difference and the shower was really pumping the water through much to quickly and emptied a big bucket in minutes .

By adjusting the flow with the small valve on the head , I could get the water hotter by cutting the flow and also cut the water used . My question is - does cutting the flow like , that put an undesireable strain on the pump which is tyrying to force the water through ?

I built a neat set-up for the shower . I bought a telescopic two piece tent pole and attached it to the underneath of my roof rack with s/steel hose clamps . The pole had a flat section on the end and I put a s/steel bolt through this and put it on with a nilock nut . The bolt sticks up an inch and is the same diameter as the locating hole in the shower head , so this sits on the bolt and is held there by a s/steel butterfly nut.
I bought a shower tent for $79.00 from Boots and this sits nicely next to the car . The tent pole extends out over this . The bride is very pleased with this new addition .

Cheers ,

Willie .

If you are only getting a small amount of control over the water temp via the heater controls - the installers probably about-faced the hose route. I get great control over my Glind, and inserted the unit AFTER the heater core - i.e. on the return line back to the block. By operating the heater control valve, you essentially let water into the heater core in the cabin where it "radiates" heat - i.e. gets rid of excess temperature. I you get the hot water going through the core first, and then into your shower's heat exchanger, by simply closing the heater core off you get the hottest water going though the heat exchanger. If you fully open the heater core valve, then water is much cooler as it has already radiated heat into the cabin - and you get a cooler chower. Then you have a heap of control in between.

I use the FlowJet 4L/min pump in the shower I installed into the Patrol. I found that the 12lpm pump just shoves far too much water thought the heat exchanger and the result is a cold shower. If you restrice the flow via a hshower rose-mounted slide valve, then you will get the hotter shower - as you have said. I've spoken with FlowJet in the USA and they don't reccomend restricting the flow of the pump for too long.

How's your heater control sensitivity when you close off the shower rose valve?

Gday Willie

I've got a 100series TD and the ARB guys told me that they install a larger heat exchanger as this model idles slowly and cooler than required for optimum shower temp. They also told me that this "newer" model is not dependent on the cabin heater control and to simply alter the flow from the rose... and that the pump had a pressure switch so no harm done.

Chrispy and John ,

I really appreciate both your comments . I will investigate the hose routing and will check the make of the pump and see if the Company says it is OK to restrict the flow .

John , I also have a TD .

If the pump is a Shurflow or Flowjet , then stopping the flow of water is no problem.

They have an internal shut off.

These pumps are used for pressurised water systems on Caravans and boats.

Turn the taps on , the pump starts and water flows. Turn the taps off the pump stops.

I spoke to a guy from Glind Showers a couple of weeks ago about the exact thing

Hi John, I use a glind pump with about 10m of garden hose with a sand filter for when I draw water from creeks, rivers etc. Also inside the hose I have inserted a one way valve with makes lifting water up inclines much easier. The filter and one way valve are available from glind.

G'day fellow campers and 4WDer's,

Following the subject of portable showers, thought you might be interested in checking out a little ripper that I've stumbled across on the net.

A friend of mine advised me to purchase a Jimmy's Thunderbox portable camping toilet, and in the process of doing so on the website, I found a brand new portable shower concept!

It's called the 'RAINMAN HOT CAMP SHOWER' and does away with all the batteries, pumps, hoses and what have you for good!!

It's a totally self contained unit and all you have to do is fill her up, heat her up and away you go - nice hot streaming water at your fingertips.

The 'THUNDERBOX' people really have the camping market up their sleeves with the portability of their products.
Big thumbs up to them, and a big thank you for making our camping lives so, so much easier!

Check this little ripper out at or the direct link to the RAINMAN page is

Take it easy all and happy camping!

Interesting concept..... :)

Do you have one, or have you seen one in use? Looking at the figures, even at the highest flow rate (shower rose tipped right down) it goes through 15 litres in 5 minutes - which is 3 litres/minute - not a really high flow at all. Maybe the shower rose has really fine jets that still give good pressure and as such doesn't need to use as much water as the AAA water-saver head that I use on both my Glind and Coleman Hot Water On Demand systems.

The website doesn't tell me what you pay for one of these - but I'd be interested to take a look at one - I think it's a good concept.

I'll try calling today...

Thanks for the info!

I just rang the manufacturer. These units are still in the prototype stage - and won't be production-ready for at least another couple of months. No pricing yet either. Shelley (the manager?) will get back to me when they're ready to go - or at least when they put some photos up on their website showing one in use.

Gday all

Thanks for the replies. I went to Thornleigh Bunnings last night and bought an inline irrigation filter, some snap on connectors (the same ones used by ARB) and 15m of hose for $7.95..... so will put it all together and see what sort of a shower Twine and the Abercrombie river can provide over Easter.

If the inline $4.00 filter is no use, I'll fork out for the one on the Glind website.

John - be wary of the "Gardena" type clip-on hose fittings. If you use one on the suction side (i.e. "input"), then these fittings are a right royal PITA. After only a little while, they start to loosen and flex a little, letting air bubbles into the line. When this happens, you get a really on-off "spurty" cantankerous shower. Much better idea is to go to a Pirtek (or similar) store and grab yourself some air line pressure hose fittings that snap together, or use screw-together garden hose fittings in-line.

Fixed all my initial problems this way....

Cheers :)

I agree.

I've ditched the Garden hose stuff , and gone to Airline Hoses and Connectors. They work extremely well.

Also on the temp issue.

Another idea folks are using (and I'm about to change to) , is to run a seperate Heater Valve inline to the Heat Exchanger. Allows temp adjustments from under the bonnet , and , if need be , can be used in conjunction with the vehicles heater controls.

I guy I know actually has his setup , with the cable , so it can be adjusted whilst IN the shower.

I'm also toying around with the idea of a Mixer style set of taps to better adjust water temp (like glind use on boat instals).

John ,
Where are you going on the Abercrombie ? I own the land between the Isabella River and Abercrombie River Junction . It is very rugged with hardly a flat place to camp , but very beautiful .
In the winter the trout run up there out of the dam , but in summer, it gets to hot for them and we are just left with rotten monstrous carp .
I hope the weather is good for you - Easter is the most pleasant time of the year to go down there .
Cheers ,
Willie .

A mate owns about 750acres on the river near Tuena. We leave the council road about 2kms from Tuena and have an hours 4WD to get to the camp spot on the river. He had to put some track through and as you say it is pretty rough... but once there, brilliant. We end up camping below the Yarraman ridge near Morris point. As you say the carp are everywhere. We head up there most long w/e's and any other time we can get 3-4 days in a row minimum.... have been for some years now.

One thing I'm surprised nobody has mentioned in any of these posts is the desirability to NOT shower close to our water-ways.....not if you're using soap/shampoo etc anyway. The run-off will pollute the river/stream etc.

I prefer to collect my water in a bucket and take it to the shower set-up on the patrol, which I always park at least 30 meters from any river etc.

Not trying to give the impression that I'm some raving greenie lunatic, but I do care for the environment I love so much.

Yep, totally agree with ya Roachie...

There was a similar discussion here not so long ago, and I'm amazed that people continue to talk about drawing water directly from rivers/streams for washing/showering etc.. W-a-y too close!!
(In fact, anywhere below "high water" mark is too close for such activity, IMO)

I agree in general , but lets not jump to conclusions.

One , it wans't actually mentioned it WAS for showering purposes , just assumed. Plenty of people use these pumps to refill , tanks, bladders , jerrys etc , to take away to shower etc.

There are biodegradable soaps and shampoo that cause no problems.

But yes , I agree about showering to close to rivers/creeks.
