You were all helpful when I wanted to know about 3 way fridges, so hopefully you can help me out with this query. It's a bit more complicated than the last one :)

An idea has formed to attach storm water piping around the top of our cruiser canopy frame so that we can have shower water etc at will while away on the beach.

So far we have cut the piping down, joined them and put a 2 way tap on one side. Problem is, is that at the moment we've attached the piping(along the top inside of the canopy frame) roughly with rope to hold it up til we find something more suitable.

We have tried wire (obviously not the piddly stuff) but looked a bit risky (all up, the piping would hold roughly 40 L to 60 L of water), bought some extra thick zip ties but they fell a little too short.......thought about joining them together but a bit wary about that as well. I did think of getting clamps but am thinking that after a while they might rub through the pipe and put holes in it.

So right now, we're at a dead end. It was an experiment to begin with but now we've gone this far and the clocks ticking down the time to when we leave, I'm starting to panic a tad!

Anyone have any suggestions?

I'd use the steel hose clamps as you have mentioned. Just line them first with a strip of inner tube rubber about 5mm wider than the clamp. Don't do them up too tightly or you'll crack the pipe.

Also be very aware that you carry an additional 60kg of weight up there..... and the inherent instability you'll suffer.

go to a plumber shop and get some proper mounts with backing plates. bolt the 2 piece mounts together and bolt into the veticcal uprights of the cage. simple as.
the cable tyes will work but get nice and thick ones. there is no prooblem in joining them togther . however get some garden hose to cushion the PVC pipe from rubbing in the roof rack. go go around the car 2 twice a day and retighten the zip ties to they settle.

Try Unistrut...can even get mounting blocks so that pvc pipe is fully supported before using clamps if you want....should be available Aust wide

The pvc pipe should be either sewer (new of course hahaha) or pressure piping ....not stormwater as its too thin.

kyako.

One additional point now you have the mounted solved. Make sure you install an additional tap located in the top of the pipe to allow the air to get out while filling the pipe.

kyako,
Binder engineering make a range of Pipe Supports, Guides and Clamps I have there cattle dog I can email to you if you like all you have to do is make sure you pick the right clamp they come lined too and I totally agree with using the Sewer or Pressure Pipe for the job.
The other thing you could do is use Pressure pipe and put a one-way hose fitting at one end then you could slightly pressurize the System to make the water come out easier? Just my idea some one correct me if I’m talkingbleepe.

I made some mounting brackets for the 100mm pipe we have at the front of our roof rack that haven't moved at all in 6 years. I used threaded 5/16th steel rod. Covered it with some 5/16th rubber hosing and then bent it to the shape of the pipe using a wooden former. A pipe bender would also do. The rubber hosing ensures that it can't move when tight. Then made a backing plate from 1" steel strip and mount with lock nuts. You would probably need 3-4 of these down each side and 2 at the front or back.

Are you planning on showering directly from the piping or is that just a storage tank? If the former how do you intend to heat the water? If by the sun you may want to consider painting the pipes with matt black paint to absorb more heat. Also if you've joined the pipes with the normal "cement" I'm sure that the water will not be suitable for drinking so be aware of that, especially with kids who are probably not averse to having a dring under the shower.

It's just really for storage purposes. We have a separate operation for the shower, as well as for the drinking water.

About what you said about painting the pipes black though - I heard something today about how the pipes may get brittle from heat/sun which may cause pipe to crack. They suggested that we paint the pipe to prevent this. Is this something you have heard also or were you just referring to heating the water in the tank?

Thanks

Kyako

All "plastic" goes "off" over time if left in the sun. My comment was about heating. Depends on how thick your pipes are, and the time they will spend in the sun, as to whether you need to worry about it. Sorry I have no specific info on that aspect - maybe ring the pipe manufacturer - they should have data on it.

Not only that but standard PVC tubing in not suitable for storing drinking water as it contains lead.

Definetly keep an eye on the weight one way or the other. My Rhino racks allow 25kg per rack. They also said to allow a factor of 1.5x when on corrugated roads. So max loading is 33kg for two racks to keep it on the safe side.

Cheers,

Glenn.

40 to 60l is roughly 40 to 60 kg. A lot of weight to be carried "up there".

Might be worth fitting some sort of baffles , to stop the half empty pipes , from sloshing around too much. May not be enough to upset the balance though.

yes baffles would be a definite must I would think to carry water in this manner.

I would use sewer not storm water its stronger.

All the best

Eric is correct.

The 90mm diameter stormwater grade pipe is quite weak and become brittle quickly as it is not designed to be in sunlight.

The 100mm diameter sewer grade pipe is more durable.
