Frequently Asked Questions (FAQs)

1. What is a float on a sump pump?

A sump pump float switch acts as a level sensor to alert your pump to rising water levels in a sump pit. As the water level rises to a certain point, a pump's float switch will open a circuit which allows the pump to begin pumping water up and out of the basement.

2. Where should the float be in a sump pump?

The Float Switch should hang a few inches above the top of your sump pump motor. The exact height will vary depending on the size of your sump pit and the power of your sump pump motor.

3. Can you add a float switch to a sump pump?

Installing a new float level switch will turn a regular sump pump into an automatic one. You simply need to use a float level sensor with two switch points (High and Low) such as the FLE series, and a powered pump relay such as the inexpensive RCU-7000.

4. How does a sump float work?

A sump pump float switch detects flooding in the sump; it's what turns your sump pump on and off in response to the amount of water in the sump pit. The device relies on a round float ball to measure liquid level, like a beach ball that floats on top of the water. When the water rises, the float rises with it.
