The Free-Flo® Anti Siphon Water Valve is a replacement valve designed to automatically maintain water level and help prevent water overflow in livestock tanks and troughs. The valve mounts through the sidewall near the bottom of the tank, keeping it out of reach of livestock, and provides an adjustable water level from 4" to 20" above the valve. It can also be installed directly into a Freeland drain and is the preferred water valve for Varnan Waterers.
