Auto Tank Fill

Auto Tank Fill

Do you have an operator constantly monitoring your water tank, and concerns of high hydrant pressure?

Free up your operator and stop being concerned with high hydrant pressure with the Waterous Auto Tank Fill System!

Waterous designed this system to solve both of these problems, and it maintains a constant low pressure water supply at the pump intake by automatically filling the water tank and maintaining a water level between 20 and 80%.

The Auto Tank Fill is designed for any of the Waterous electric-actuated ball valves (sold separately).
