Roof Rack Water Storage Pipe

Hi all, I'm thinking of extra water storage for our CSR trip.

We currently have a 50 litre tank behind the second seats, plus we carry one or two 20 litre containers on the roof basket. However, I'm not really happy with the two containers for this trip as they take up a lot of much needed basket space.

Has anyone any experience with setting up a pipe storage solution for carry bars. The Cruiser has 3 bars with space for a pipe, and I am thinking that a 2 metre length of 20mm int. diam would give me a very useful 63 litres capacity.

Cheers.

Err, John. You seem to have slipped a decimal point.
2 metres of 20mm pipe would hold only 0.63 litres.
Did you mean 200mm pipe?

Cheers

....errrrr...... Yes, sorry, meant 20 cm, but I've since looked at some pipe and I am now thinking 15cm internal.

Cheers.

Use or paint the pipe black & you'll have hot water!!

John, if you sre thinking of poly stormwater pipe with the blue glue for the ends there have been cases in the past where, after prolonged time in the sun, the glue has poisoned the water and people have become very sick drinking it.

cheers

Spent about 20 years making PE and PVC pipes ... I know what goes into then, and not all are safe for Potable water.

Avoid stormwater and DWV/sewer pipes as the stabilisers used in manufacture are lead based and will leach into sitting water.

White PVC pressure pipe is generaly OK as they phased out lead stabilisers in these in the early ninetys.

As for the glue tainting the water, never heard this one.

Water kept in these types of roof top "pipe tanks" is the perfect breeding ground for nasties. Stitting water, warmed by the sun will breed some nice bugs.

Drain it between uses, fush before use, and maybe consider a flush with with bleach as well.

John,
Gone Bush is right ,the blue glue is not suitable for pipes used for drinking water,but there is a glue that is green made for contact with drinking water that is suppose to be safe according to labelling. you will find it generally in the same place in hardware stores as the glue glue.
cheers John.

Hi John,
I have read somewhere that the PVC glue becomes toxic when heated and contaminates water stored in contact with it.
I don't know it for a fact but it is worth checking with someone(Google??). Maybe I will do that now.

John,

63 litres of water moving on the roof rack is not going to last the trip. I have seen full length steel roof racks give trouble on the CSR because of the load moving about. Take 10 liters of water out of the pipe and you will have approximately 50 kg moving from front to back every time you go over a sand dune.

I can understand your need to carry water but I have also found that many of the wells have good water for washing and cooking. Evan after boiling the well water it is OK to drink in moderation.

I would be looking at trying to get 10 lt water containers spread around the vehicle. A 10 lt container is small and not as heavy to pick up from in side a vehicle.

Keeping the weight off the roof bars as much as possible will make the trip less stressful.

Wayne

Thanks Wayne - good considerations.

I am now thinking that if I do go the pipe route, I might put two 10cm pipes up side by side against the basket (which is half width) which would go to solving the major sloshing issue of a bigger pipe size.

I'm not too worried about the extra weight because I'll have most of my heavy weight down low with only lighter bulk up top (apart from the water). I will be well inside the 150kg Rhinorack load rating.

With all the other stores, I'm going to have difficulty putting extra containers inside behind the cargo barrier unfortunately and I really don't want heavy stuff on the people side of the barrier.

I know the water won't last the trip and I'll be topping up periodically. I want to carry the extra in case of breakdown (I'll be hitting the CSR at well 23 after getting there by the remoter tracks (Eagle Hwy, and eastern Talawana).

But I may resort to a 35l water bladder as supplied by ARB if I become convinced of the downsides as you and others advise.


Cheers.

go for the bladder mate, weight down nice and low, must be safer and no need to worry about toxicity, thats the way I go and no worries about rack strength ether.

I would also heed Waynes advice if you dont use the bladder, he is a veteran of many CSR trips, and has seen it all over the years.

Cheers Colin.

On our CSR trip some years back, we just had 4 jerries of water mostly inside and a small quantity on the roof. (Two adults+4kids). I put a label on each jerry and as it was refilled from a well, that info was put on it. That water was just used for washing cooking etc and the original was the drinking water. At the end of the 3 weeks we still had plenty of 'drinking' water left and the rest was well water. This system has worked well (so to speak).
