Float Switch triggers for Back Up Sump Pump is important because
Each backup system has a trigger that activates the non electrical power source to begin operation.
What are the different triggers?
For battery powered backup sump pumps, when the water level raises the float, the battery is activated into operation.
For water powered backup sump pumps, when the float raises, a valve allows pressured water to flow down to the pump. The flowing of the pressured water activates the backup system into operation.
An automatic start standby generator is activated when the transfer switch senses a utility power interruption.
A portable generator becomes operational when a human starts it.
What are the advantages and disadvantages of each trigger?
The transfer switch for the standby generator is the most reliable and quickest way to activate the operation of a backup system. The backup pump is operational as soon as the power goes out.
Battery and water powered systems are not activated until the water rises to the height of the float. That means water has already collected in the pit.
How dependable are the different triggers?
Batteries deplete and loose charge.
Municipal water pressure is not constant. A drop below 40 PSI means the backup system is not operational.
The float-switch mechanism, impeller or clogging of the backup sump pump plugged into a battery or standby generator source of power could fail.
Dual vertical switches offer twice the reliability.
