Can you adjust a vertical float switch?

Adjusting a manual float switch is easy. Start by moving the rod or tether up or down based on the water level in the pit. Most systems can be adjusted by hand or with a normal sized screw driver. Shorter tethers and rods work best for lower water levels while higher tethers and rods are better for higher water levels.

How do you open a float switch?
