The Water Block valve is an overflow safety device, which controls the maximum continuous flow of water between 1.3 and 13.2 gallons. Its function is to measure the number of gallons of water that have passed through it. If this quantity exceeds the set value, the Water Block stops the flow and keeps this safety condition until user intervention. If the water volume does not exceed the set value, the Water Block mechanically and automatically resets the measured volume and the Water block is ready to restart a new measurement cycle. The Water Block does not require power, simply water flowing through it.
