One little thing, the far left float should not be in the up starting position. So there should be no spring holding it up.

After the middle float drops (water low), pump goes on, middle float goes up, then left float goes up causing the pump to go off. This is wired in a latch fashion with the relay, prevents the issue of bounce due to wave disturbance action. If left float fails to go up due to snail or just failure, the right switch is a backup to shut pump off. There is a separate circuit for audible alarm if right float activates. Audible alarms use 555 timers.

Willing to make another to sell?

[TooManyHobbies58]

I'm working on another project right now. I don't have the parts either. Was going to buy the parts and make a parts kit to sell but I am not at that point yet.
