Troubleshooting Sump Pump Problems

Check the float switch. A sump pump functions like a toilet in reverse. When the water level reaches a certain height, it triggers the float switch to turn the machine on. If the switch is broken, the unit will not turn on and the water continues to rise. Take the float in your hand and move it up. If the unit does not turn on, it is likely the float switch that has malfunctioned. It will need to be replaced.

Check for debris in the unit or in the pipe. If the sump pump has sucked in something such as organic material, it will create a clog and water will not be able to get through. Turn the unit off, put on a glove and check the pipes and the unit. If the pipes are small, use a small metal rod. Feel around for a clog and if you find one, remove it and dispose of it.

Look at the check valve arrow. The check valve's purpose is to make sure that water does not enter the sump pump when the unit turns off. If the arrow is facing the sump pump, this is will not work. Turn the check valve arrow away from the sump pump.

Check the weep hole. The weep hole is a very small hole that you will find between the check valve and the sump pump. If no water appears to be weeping out of it, insert a small toothpick and carefully move it around a little. This should clear out the weep hole.

Check the power source. It may be something as simple as the plug for the unit has come undone, or the breaker controlling the sump pump has flipped. Check the cord and the breaker box.
