Waterblock is a water fuse that shuts off the flow to the dishwasher or washing machine if the filling exceeds normal. The fuse is mounted between the hose to the dishwasher and the mixer. If a refill is greater than the set value, the water is automatically turned off. After each refill, the Water-Block is reset and a new refill can be made. Can be set between 5 and 50 litres.
