There are a variety of factors that could cause your sump pump to run continuously, but regardless of the reason, a sump pump that runs without stop will burn out more quickly than a sump pump that runs intermittently. In other words, fixing a continuously sump pump is critical. In the majority of cases, the problem originates with the sump pump float switch, and can be fixed by the homeowner.
The sump pump float switch is a mechanical float that controls the power to the sump pump. When the float is tilted upward, the switch inside the float turns on, thus draining the tank. When the tank empties, the float tilts downward. When this happens, the switch inside turns off, and the tank begins to fill with water again.
There are many things that can go wrong with the float switch that could cause the sump pump to run without stop. In some cases, the switch will become tangled with or pinned to the edge of the liner by the sump pump itself. When this occurs, the floating switch may not be able to rise and fall with the water, which can cause it to become stuck in the “on” position. In other cases, the switch may break while in the “on” position. All of these problems will cause the sump pump to run continuously.

There are other problems that can cause your sump pump to run continuously. The sump pump check valve could be defective. Your sump pump could be too small, or the pit could be too large. There could also be a sewer leak under your house, or your sump pump could be poorly located in a location just below the water table.
