Does the Automatic Watering System work with a rain barrel or gravity fed system?Updated a year ago

No, our Automatic Watering System requires a consistent pressure of at least 15 PSI to work correctly. That said, if you add a pump or some way to ensure that minimum, continuous PSI is met, then it should work, but we cannot guarantee it. That's because our AWS is designed to connect to a hose or spigot to work as intended.
