Plumbing

In the van there will be a small plumbing system. Since I don’t have a shower, and also don’t need an outdoor shower, its limited to the kitchen area only.

I also don’t have water tanks underneath the van, since I don’t need huge amounts of water. Also, I don’t think it’s hard to get water, so no need to take huge amounts with me.
So i went with 2 small portable water cans of 20 Liter each (5.3 gallon). If needed, I can fill a 3rd one and store it in the back.
Both of them can fit in one of the kitchen cabinets. One will be used for fresh water, the other one as grey water.

I use a small submersible pump, which is connected to the kitchen faucet. Inside the faucet is a small microswitch.
This switch is connected to a small relay, which switches the actual pump.
Some people are reporting issues with the small micro switch switching the inrush currents of a pump, so I added a relay, to save the microswitch.

I also installed a small 12V / 200W boiler. This can hold 6L water (1.6 gallon). I also added a switch so I can disable the boiler if needed to save some power. (I calculated the boiler to use approx 35Ah battery capacity, so it’s quite a heavy user…

The boiler is a plastic one, with rather crappy insulation. I’ve installed it below my bench. In order to add some insulation I’ve wrapped it in some 9mm Armaflex leftovers, made a small box around it, and filled that with sheep wool.
And it did fit perfectly, I had just enough to run the duct from the Webasto heater through this compartment as well.

Both the boiler and the water tanks are in separate compartments. I’ve covered both with Vinyl floor liner. Also made all sides fully watertight for at least 3cm (about 1 inch). On the back, there is a gap of 5cm widht (2 inches), so if anything starts leaking, it will leak into the structural framing of the van, which has holes in it so it will drop straight to the ground, instead of damaging my floor.
