Detecting Pump Failure through High Level Detection

In any case that there is a problem in the sump - there is one common result - the water level rises above the pump. Level Sense uses a custom designed bracket which detects the water level if it comes over the pump. Other systems use a tethered float switch which has a potential to get caught on the pump or the walls of the sump. The mounting method keeps this magnetic detection device clear and uninstructive of the operation of the sump. Notifications are sent out immediately upon high water detection to contacts of your choosing. There are unlimited email and text notification destinations.
