ALC 1275


Out of Stock

This automatic water level sensor is designed to provide complete control of the pump and motor. As long as there is ample power to the pump, the ALC 1275’s automatic power function will turn the pump off when the tank is full and restart when water is needed. It also has a built-in time delay to prevent surging. This smart investment saves a lot of unnecessary wear and tear on the pump and greatly increases its life expectancy.
