Here, we explain the reasons your sump pump might be failing to shut off and what can happen as a result.

Why a Sump Pump Running Constantly Is a Problem
The purpose of a sump pump is to eliminate the threat of excess moisture. It also prevents water from damaging your home’s basement or crawl space. Sump pumps are designed to detect excess water and go into action. As water builds up, the sump pump begins pumping the groundwater away from the foundation.
If a sump pump turns on and runs constantly, it can result in serious problems. It can be at risk of malfunctioning and prematurely wearing out the motor. This decreases the system’s lifespan. If it fails, the downtime increases the risk of potential flooding. When this happens, property owners must have their systems repaired.
Reasons Your Sump Pump Won’t Turn Off
Sump pumps often show warning signs that a bigger problem is occurring. One of the telltale signs that a system is experiencing issues is a sump pump that doesn’t stop running. The reason a sump pump constantly runs can be any of the following:
Defective Float Switch
The float switch is what signals the sump pump to turn on. Situated atop the water, it moves up and down with the water level. When the water hits a certain level, the float switch starts the pumping process. The submerged pump pulls water in and moves it through the discharge pipe.
When a switch is defective, this can mean that the float and arm are stuck, and it can fail to pause after releasing water. This can cause the system to run constantly and not shut off.
Broken Check Valve
Above the sump pump is the discharge pump. That’s where you will find the check valve. This valve is important, as it keeps water from flowing down the discharge pipe and back into the sump pump. A malfunctioning check valve could cause the water to constantly move up and down the discharge pipe without being dispelled from the system. If this is the case, your sump pump will keep running.
Clogged Discharge Pipe
If the float switch and check valve aren’t the source of the problem, a clogged discharge pipe may be why your sump pump doesn’t turn off. Over time, dirt and other types of debris can make their way into the discharge pipe, causing a blockage. This clog prevents water from exiting the sump pump, causing it to run constantly.
Undersized Sump Pump
Sump pumps must be able to expel water at the same rate that it enters the system to be effective. However, an undersized sump pump can make this difficult. When a sump pump cannot keep up with the incoming water, it runs longer than it’s supposed to keep up with demand.
