These one-way check valves keep the water in a drip system from flowing back into your home water supply if there is a sudden loss of pressure.

Check valves can also be installed on the downward slope of a hill to prevent water from draining back down the hill and over watering lower areas. They are also commonly used in pump systems to eliminate back pressure.
