12/14/2010 – Do the ULTRA Pumps have an automatic shutoff if the water level drops below the required level.
Response From TJB-INC: No. They will continue running until no more water goes into the intake side of the pump. Rule of thumb ... try not to let any pump run dry. The water acts as a lubricant and also keeps the motor cool. If the pump runs dry, damage can be done to a pump.
We do sell a separate low water pump shut off switch.
