WATERBLOCK is a safety valve that monitors water volume between 5 and 50 L (1 and 13 gal). Its main function is to measure the quantity of water, through a specific setting on the device. If the set value is exceeded, WATERBLOCK immediately blocks the water flow until the user manual resets the device. Installing WATERBLOCK on faucet taps protects equipment and appliances, as well prevents any leaks or flooding from happening.
