Submersible sump pumps are activated by a float switch. When the water in the sump basin reaches a certain level the float will activate the pump. When the water level comes back down, the float switch will turn the pump off.
Titan Submersible Sump Pump Float Action (shown in animation)
"Tethered" Float Switch Pump
"Vertical" Float Switch Pump
The sump pump float hangs from the pump and rests on top of the water
As the water level rises, so does the float which will activate the pump
When the float reaches the maximum appointed level, the pump activates to remove the water
The pump will continue to run until the water level lowers to the minimal appointed level
The submersible pump will shut off when the float again rests at the minimal appointed level
Float Switch Sump Pump Types
There are two main options when selecting the right residential electric sump pump. First option is the horsepower of the pump, which in part determines the water flow rate. The second option is choosing the submersible pumps float type. There are two different types of float switch sump pumps available, vertical and tethered.
The vertical float is the preferred type of switch because it has a very limited range of motion, meaning there is less chance of it getting stuck and not activating the pump.
The tethered float is the most common type of sump pump. The float is attached to the pump and floats on the water. As the water rises, the float rises to turn on the pump.
Tethered floats have been known to potentially get stuck on the pump or the inside wall of the sump basin, preventing the float to activate the pump, which could result in some flooding.
