How Do Sump Pump Floats Work?
Before we move on to why you need to adjust your sump pump float, let us understand what a sump pump float and sump pump float switch are.
A sump pump float switch detects whether there is flooding in your tank or not. Therefore, it deactivates and activates the sump pump according to the water present in the well.
The device relies on a round ball that measures the liquid level, like a beach ball afloat on the water surface.
When water starts to rise, the float also rises with it, and once it reaches a specific height, the switch inside closes.
Why Is Sump Pump Float Adjustment So Important?
Without float adjustment, your sump pump might not efficiently carry out operations, and it might even lead to flooding or excessive strain on your unit.
One of the main reasons float adjustments are required is that sometimes the sump pump float is entangled inside the basin.
Often it is trapped between the basin wall and the pump, and it cannot drop or rise to desired levels. However, you can easily repair this.
Another cause is the mechanical failure of any switch components. If that is the case, your switch must be replaced.
