On the back of the farm, you will find two spigots located directly below the electrical box. The right spigot is used for filling the tanks. The left spigot is used for draining the tanks.
To allow the farm to operate year-round, the water must be hard plumbed with piping running underground. The section of pipe protruding from the ground connected to the spigot must be insulated and wrapped in an electric heat cable to prevent freezing.
Flush out newly installed piping thoroughly before making connection to farm to ensure no pipe debris enters container, which could lead to fault in the solenoid valves.
