The only point that must be taken into account when making a decision to install automatic crane cranes is the minimum working pressure of these mechanisms. The specifics of the operation of the locking mechanism of these cranes are such that the water is finally locked by water pressure in the water supply. Manufacturers of Poland and Italy in the characteristics indicate the minimum working pressure of 0.5-0.6 atmospheres (for German production cranes 1.2 atm). If the pressure is lower — the crane of the dispenser will not completely overlap the water and it will drip from the spout. At the same time, some models make a specific hissing-visual sound. From the experience of work, I advise you to install automatic cranes of Italian and Polish manufacturers on a water supply with a minimum pressure of 1 atm. Then you certainly will have no problems with operation. For the Germans, respectively, 1.2 atm.
