Plastic Jerry Can Flood

Drill out the hole to suit a rain water tank outlet, the brass type that has the male threaded piece and a seal on both sides/ nuts that clamps to the wall of the tank.
Robust, servicable, versatile.

Ps, cant use firefox to reply, and even explorer has issues with this java stuff.

One of our "never go anywhere without it" products Shoo Goo , will solve that problem Stan.

Where they the cheap one or the better Rheem ones?

This is made exactly for your situation, ask a plumbing or rural supplies .......
BLIND FIT OUTLET

G,day Stan

I use these. Those drum taps are hopeless as they break all the time as you have found out!

Lid Tap

Two very good solutions there Shaker and Bushranger. Just logged them into the good ideas book

Thanks, Bruce.

Ended up fitting an agricultural barb fitting into the can, with some teflon tape, as that was all the nearest plumbing place could offer. It was the thread on the tap that was gone not the can. Then a hose clamp, a short length of 13mm pressure pipe and an agricultural 13mm tap: works well. Thanks everyone.

Safari Can with pump in lid in a Toyota

Can send to you, anywhere in Australia one of our new Australian built Safari Cans with a manual water pump fitted to the lid. Go to www.safarican.com.au to view.
They are a roto molded rain water tank storage container with a food grade silicon seal, designed to go into a jerry can holder.
The Safari Can if completely full may weep a little around the seal under the lid in serious offroad or heavy braking but it won't leak out the bottom as it has no holes there. And when you want water just use the caravan hand pump, bonus is you can use Safari Can for other uses like esky and general storage as well.
They are $225 for a standard grey can. And $275 fitted with the pump and drinking water hose, plus $25 postage anywhere in Australia.
Good luck and enjoy your trip.
