I use the pump as an isolated solution to wake up at home in the bathroom. Ie. From the 35-liter canister, which is also available from SVB, it pumps the water over a 13 mm hose "high" to the washbasin (about 1 m difference in height). The hose is provisionally attached to the tap with a cable tie. To wash your hands without soap it is enough to step on the pump once. With little soap you need 2 strokes. For heavily soiled hands more accordingly. The advantages of this solution are perfect hygiene after using the toilet, because no faucet has to be operated with the hands (keyword "EHEC") and an extremely low water consumption, because the water can be dosed exactly. It takes a bit of patience to fill the vessels with water. The specified max. 8L / min are unrealistic, because you can not step on the pump like crazy, but have to wait a short time (1-2 seconds) after a stroke, until the pump has reached the starting position again. During a test, I needed exactly 40 seconds for 1 liter of water. As a field of application I can imagine here also Plumpsklos (eg in the garden) to create better Hyghiene here.
