Spotto has a simple fresh water system built into her kitchen. It consists on a 40 liter container with a bottom brass fitting and a clear plastic hose connector to a small 12 volt electric pump. The pump pulls the water from the tank and pushes it through the faucet. The drain water is collected in a removable aluminum bowl set into the kitchen countertop. There is no drain. Drainage is performed by manually “picking up the aluminum bowl and tossing the water”. Like I said – it’s all very simple. The hardest part is refilling the 40 liter container which lives under the bed. I fill it with another 40 liter container that I keep next to the house battery compartment or from a couple 10 liter bottles we use for drinking water. I use a funnel to pour from one container to the other.
The only problem we have is that the pump loses its prime. There is an air leak that I can’t find so I solved the problem another way. I added another clear plastic tube to the top (fill point) of the 40 liter container. To re-prime, all you need do is blow into the tube. This adds pressure into the tank and forces some water into the line between the tank and the pump. This clear plastic pipe is easily accessible under the bed just behind the kitchen counter.
