Efficient Solenoid Valve (130258-I)
We have in our house a reverse osmosis water filter for filtering the tap-water up to drinking water quality. The filter fills a little reservoir of 25 liters. We used to manually turn on and off the tap of the filter, but of course, as it takes 4 hours to fill the reservoir, we usually forgot to close the tap, spilling lots of water.
