Zilmet WATER-PRO Expansion Vessels 5 Litres Compact design with seamless diaphragm inhibits bacterial growth. Zilmet WATER-PRO tank leaves the factory already tested and pre-pressurized. When the pump starts, water enters the tank as system pressure passes the minimum pressure pre-charge. When the pressure in the chamber reaches the maximum system pressure, the pump stops working. The tank is filled to maximum capacity, and when water is needed again, the pressure in the air side will push the water into the system.
