Moin,

I am fininishing my project for a convertible auxiliary fresh water storage tank. My design goal was to design a system that is user friendly in which one can select which of the two water tanks to draw water from. The auxiliary tank adds about 49 litres of fresh water capacity. It can also be easily removed if cargo capacity is desired. Total project cost of about $300 USD.

tank shopping


fittings shopping


initial fit check


a key component of the dual tank system


each tank has its own pump is the key to a simple dual tank system


consulting to the water system diagram - no much help there due to lack of electrical circuit schematic


experimenting with many different ideas for filling and draining


the break through ideas came with the excellent Colder PLC series quick connect fittings


a marine deck plate is fitted for accessing of the pump parts as well as serves for gravity filling if necessary


bench testing of many design ideas



old toilet waste drain (only in NAFTA JC) is to be re-used for overfill drainage


design concept bench test was a success



the assortment of Colder PLC fittings - these make the convertible design elegant and user friendly


the quick disconnect for the pump hose with the Colder PLC fittings


the main pump shut off switch is replaced to select which of the two tanks to draw water from

the new switch for - Primary, Off, Auxiliary


connectors for the auxiliary tank pump cable


modifying the steel cover under the wet cell


the tank is secured by 3 cleats and one tie-down strap for easy removal - no tool required


this is what the finished auxiliary water tank looks like


I wrote a 7-part blog posts for this project from the initial idea to final configuration of the almost finished project. http://eat-drink-men-women.blogspot.com ... art-1.html

Also ich finde, dass die 100 Liter im Cook echt lange reichen.
Gut, ich lasse beim Zähneputzen auch nicht das Wasser laufen und giesse meinen Vorzelt-Rasen auch nicht zweimal täglich

Aber ein netter Umbau.

Martin,

Thanks for the comment. I agree 100 litres is quite a lot of water. I treasure the water when I am camping, and a tank often last me over a week, and this including cooking all the meals. Some times I visits cities or travelling on long journey, it can be hard to replenish the water and this auxiliary tank will come in handy. I was staying in New Orleans last winter for over a week, and eventually I have to leave the city to find a state park to refill the water. Having more water capacity I can reduce the need of driving around to find water. Also it is a good feeling that you know you have two full tanks driving into the Death Valley https://en.wikipedia.org/wiki/Death_Valley infested by thirsty German tourists . It is rather like riding into Das finstere Tal https://de.wikipedia.org/wiki/Das_finstere_Tal with a superior Yankee Winchester rifle .
