Just wondering if anyone has used the PVC Conduit method on vans for extra water storage and if so, how they went about it. Also a rough idea on diameter and length used............

Thanks in advance people

Hi Kevmac,

Do you mean the 6 inch white PVC.

If you go down this track remember algae will start to grow if water is stored for some length of time. lets sunlight through.
Painting the PVC thoroughly with black paint should help.

Keep in mind that it is not a food grade PVC so I would not use for drinking but fine for anything else.
I don't know how much storage you are looking for but the larger (6 inch ish) sizes can get get pretty expensive with the cost of the fittings etc. have a look at them in Bunnings to get an idea.
There are a lot of poly tanks available on eBay and through 4wd shops that are only a couple of hundred dollars and may be a more suitable alternative ?

You would have to install some sort of baffle inside it or the water will slosh around, I also would not use it for drinking water, but for showers it would be ok

Do your maths on storage volumes. PVC piping does not store that much water for its length.
You would be much better off fitting another poly tank into your system under the van or ute if possible.

Hi kevmac, I'm thinking you will need to be careful if you are thinking of putting this water storage high up on your van ie. on the roof, as it will change the C of G, this combined with water surge and the transfer of weight could have you in all sorts of trouble when rounding corners or stopping.

G`day Kevmac,
Not what you asked, but as others have said an additional caravan poly tank will supply a larger amount of quality water with less hassle.

A rough calculation is that a 6" pvc pipe X 2m long will only hold approximately 36.5 ltrs.

I don`t know where i`m going but i`m enjoying the journey.

Thanks to all respondents for their advice, but have since decided against this method after calculating sizes of PVC pipes that would be needed. In for a trip down to my local caravan dealer to see if he has any 2nd hand poly tanks, as I do have room behind the rear axle. May even get them to fit it for me...............

Thank you once again.

I would check out Cameron Caravans near Bunnings and also the Plastics place on Alb Hwy just near Albany Belts, they have had suitable tanks there too.
I wouldn't bother chasing up a second hand one, new 55 Ltr ones were under $100 last time I was looking.
