A sump pump usually fails to turn on because it has lost power, the float switch is stuck or broken, the motor has failed, or debris in the pit is blocking the float. Checking these safely can help you understand whether you need a repair or a new pump.
Power Problems
Pumps often plug into a ground fault outlet, which can trip and cut power. A breaker may also trip during a storm. Only check outlets and breakers if you are standing on a dry floor and the area around the pump is not flooded. If there is water near the cord or outlet, do not touch it.
The Float Switch
The float rises with the water and tells the pump to start. If it is stuck against the pit wall, tangled in the cord, or broken, the pump will not know when to run. With the pump unplugged, you can check whether the float moves freely up and down.
Debris in the Pit
Dirt, gravel, and small objects can collect in the pit and keep the float from rising. They can also clog the intake. Keeping the pit clean is part of basic pump care.
A Failed Motor
If the pump has power and the float moves but nothing happens, the motor may have burned out. Pumps that are many years old, or that ran constantly during a past storm, are more likely to fail. A humming sound with no water moving can also point to a motor or impeller problem.
You can test a working pump by slowly pouring a bucket of water into the pit. It should turn on, empty the pit, and shut off.
If it does not, the pump can be tested and either fixed or swapped out. Drains, valves, and pipes in the same area can be checked during the same visit. Call JPR Plumbing at (833) 603-1840.
