The water system

More important than heating is the water supply. Of course you can keep it simple and take 5 liter bottles, but that is not very practical. Water from a large tank and using a pomp and tap is more convenient. 80 liter is for me the ideal amount of water considering the available space and the amount needed. It implies that you also need a waste water tank and an intake and an outlet. The clean water tank is integrated in the sitting area and the dirty water tank in the kitchen unit, the hose, pump and expansion vessel are mounted under the elevation, that is the transition to the cabine. The level in both tanks is monitored by the control panel on the wall.

The transition in height from cargo area to cabin is 20 cm. That space can be used for the waterpump and expansion vessel next to the heater and diesel pump. The hose is splitted in two leading to the sink en the shower head.

The intake of clean water from the outside occurs via a throughput at a right angle and the reading of the water level in the tank occurs via a monitor in the wall.  The tank can be opened from the inside and easily cleaned. 

In the lower part of the kitchen unit the water from the sink is collected.  The water can be discharged via a throughput in the bottom floor connected with a drain valve..

The hose runs behind the refrigerator to the tap at the sink.

The hole for mounting the water tap and the electricity connection of the refrigerator. I used a mold to be sure to make sure that the sink and gas burners fitted.
