What is the function of a float switch in sump pumps?

• A. To manually activate the pump when needed
• B. To activate the pump when the water level rises to a set height
• C. To provide continuous monitoring of groundwater levels
• D. To control temperature in the sump basin

Answer: (B)

The function of a float switch in sump pumps is to activate the pump when the water level rises to a set height. This is crucial for preventing flooding in basements or other areas where water accumulation can occur. The float switch operates on a simple mechanism that responds to changes in water level. When the water reaches a certain level, the float rises and triggers the switch, turning on the pump to remove excess water. This automatic operation helps maintain safe water levels without manual intervention, making it an essential component in effectively managing water in areas prone to flooding.
