A while back I posted because my sump pump would only work
sporatically. Sometime it would, sometimes it wouldn't-- which could
be a problem. After much analysis I discovered that the simple reason
was because the parts stuck sometimes. I sprayed them with silicone
and it worked fine for a long time.

Exactly what sticks? The float? The switch? Is something worn? Grease is
probably a better lubricant for this application but not knowing exactly
where it is applied, I can't say for sure.
