To test a sump pump float switch, pour water into the pit until the float lifts and the pump kicks on. But the pump only sees water the drains deliver, which is why this clip starts in a window well.

A tech in a black shirt and khakis kneels down inside a basement window well beside a brick house, scooping gravel into red buckets. The camera looks straight down into the round drain opening at the bottom of the well.
Buckets of gravel line up outside as the drain gets cleared, and on camera he says he's testing the pump once the path is open. In many homes, a window well drain ties into the footing drain that feeds the sump pit.
Yeah, that's what you want here. What happened is you can do something like this. We there in a minute. It's the full turn date.
All right, so what I'm doing is testing the pump.
Pour water into the pit. If the float rises but the pump doesn't start, or the pump starts and never shuts off, the switch is the likely suspect. Also look for a float rubbing against the pit wall or tangled in its cord. Switches can be replaced, but on an older pump it often makes sense to replace both together.
