The idea behind this design was to be able to carry a
relatively small amount of water (about 5 litres) on the
vehicle with easy access. This particular design may not be
appropriate to all vehicles with a rear mounted wheel and
dimensions will need to change dependant on your set-up.
details' diagram shows the different bits of plastic pipe and
fittings. I used ordinary plumbers pipe as we did not intend
using it for drinking water. If you want to use it as drinking
water see your plumbing supplier to get the right pipe. I used
90mm pipe as I was cautious about carrying too much
water/weight on the wheel carrier.
drilled a small hole in the plastic filler cap to prevent air
lock and secured the cap with a retaining wire so it did not
get lost. I put a circle of rubber from an old inner tube in
the cap to prevent spillage but someone said you can get these
caps with a waterproof seal now. I fitted a metal screw cap on
the threaded end of the outlet tap and drilled some small
holes in it to reduce the flow of water out of the tap and
'Bracket details' diagram illustrates how the pipe assembly is
attached to the vehicle. I used a strip of steel at the ‘back’
and secured two lengths of threaded rod so that they pass
through the spare two holes in the wheel rim when it is
mounted on the wheel carrier. You could weld the threaded rod
but I drilled two holes in the plate and secure the threaded
rod with nuts on either side of the plate. This back bracket
is put behind the spare wheel before it is attached to the
‘front’ bracket is made of angle, I used aluminium. It has two
holes corresponding to the bolts on the back plate. I glued
rubber on the back of this so it did not mark the wheel rim.
The tube assembly is simply bolted onto this angle along the
top edge, I used 4 of the circular tube clamps. The whole
assembly is then mounted onto the bolts on the back plate and
held in place with two nyloc nuts and washers.
painted mine black to help protect the pipe which can become
brittle over time in the sun. The soap dish was a joke I added
because my wife Christine said that was all it needed to make
though it is only a small amount of water we find this most
useful for camping, picnics, rinsing hands after fitting on
the trailer, etc.
