The Everpure EV9503-00 Water Block Overflow Safety Device measures the number of gallons of water that have passed through it. If the volume exceeds the set value (between 1.3 and 13.2 gallons), the Pentair Everpure Water Block stops the water flow and maintains this safety condition until it is reset. If the water volume does not exceed the set value, the WaterBlock mechanically and automatically resets the measured volume and is ready to start a new measurement cycle.
