WaterBlock
“Excess Water Flow Shutoff System”
WaterBlock Automatic Water Shutoff System
WaterBlock is an excess flow, safety shut-off valve which controls the maximum continuous flow of water through it. Its function is to measure the number of gallons of water that passes through it and shut off if this quantity exceeds the preset value until you reset it. If the water flow volume during a continuous run does not exceed the set value before it stops normally, WaterBlock automatically resets to zero and starts a new measurement cycle when the flow begins again.
For example: WaterBlock is installed into the water line feeding an auto-fill coffee maker or ice machine and it is set for 1 gallon because this appliance normally uses less than a gallon per cycle. If the appliance operates normally, it fills the reservoir and shuts off and WaterBlock resets to zero till the next operating cycle. However, if the appliance malfunctions or the water line ruptures, and the water continues running, WaterBlock will shut off when the usage reaches 1 gallon and will stay off till someone resets the valve. This prevents the damage that could have happened if the water had been allowed to keep running.
