Changes

*23 March: some pumping test with a coffee pump. Two main issue have occured : the pump is not powerfull enough it can only withstand a water column of 2 meters. The flow is also not important enough.*24 March : Second try with the coffee machine pump. The flow seems to be sufficient with a little tube. We can maybe use a double reservoir approach, one up and one down. *18 April : Basic pump testingwith the coffee pump, it only need a nice box around it to secure the 220V connection. Apart from this, everything is working fine.
