Zoeller 50/90 Series switch is stronger than the float displacement, and not turning on.

My pump's switch got waterlogged and stopped working, so I ordered a new switch and it works as intended. The issue is that maybe it's a bit too stiff?

The float on the lever is fine, I hear no water in it, and it rises along with the water level as it should, but if it's a gentle rise in water instead of a rapid rise (no rain day vs rainy day), the float is not overcoming the force of the switch to turn it on, and the water will rise above the pump itself.

Funny enough, at that point the backup pump kicks on, which causes the water to fluctuate just a bit, then causing the main pump switch to finally switch over to take the rest of the water out.

Any ideas to make the switch a bit more sensitive?

You could eliminate the switch and use this. They work great.
No floats to hang up and no mechanical switches to go bad. There are two sensors so you can set the on/off height where it works best for your situation and to reduce short cycling.

I'll keep those in mind thanks.

After breaking in the switch a bit it's behaving as normal. I guess it just ships a bit stiff.
