The Water Lock is an automatic water meter and a locking device for use on bathtub taps. What you need to do is simply set the desired volume of water for the bath and let the bathtub fill up unmonitored. You generally know how much water you would like to fill in for your bath, so after the set amount has been filled, the flow automatically stops. So you end up avoiding overspill, wastages and have the freedom to do other stuff while you run up your bath water.
Water Lock simultaneously records and displays the water volume. When the water is flowing, it is ‘on’. When the flow is terminated, Water Lock is ‘off’. It uses the principle of a combination padlock for its operation and doesn’t require electricity.
Water Lock is a 2012 red dot award: design concept winner.
