Ergo, do all boats need a bilge pump? Bilge pumps are that last line of defense against your boat sinking. Unfortunately, most boaters believe that one pump is sufficient. That is actually the bare minimum required, and three or four pumps per craft is recommended.

For that reason, how does a bilge pump float switch work?

Bilge-pump switches have two jobs: turn the bilge pump on when there's water in the boat and then turn it off again once the water's been pumped out. ... Water in the bilge raises the float and turns on the pump. As the level drops, the switch returns to its rest position and turns off the pump.

How do you replace a float switch on a bilge pump?
