Is your sump pump humming non-stop? The culprit is usually a stuck float switch, a broken check valve, or a clogged discharge line. For homeowners in Montclair, high water tables following heavy seasonal rains often force these systems to work overtime. Here is how to troubleshoot the issue and when to call a pro.
3 Common Reasons Your Sump Pump Won’t Shut Off
A constantly running pump doesn’t just create noise it burns out the motor and spikes your electric bill. In Essex County, we frequently see these three specific failures:
- The Float Switch is Jammed: This is the most common failure. As water levels rise, the float triggers the pump. However, vibrations can wedge the float against the pit wall or tangle it in debris. If the switch stays “up,” the pump thinks the pit is full even when it’s empty.
- The Check Valve Has Failed: The check valve acts as a one-way gate, stopping pumped water from flowing back into the pit. When this valve breaks, water slides back down the pipe, triggering the pump again instantly. This creates a continuous, damaging loop.
- Discharge Lines are Clogged or Frozen: If dirt, roots, or ice block the exit pipe during a New Jersey winter, the water has nowhere to go. The pump will run indefinitely, fighting a losing battle to push the water out.
- The Pump is Undersized: Did you recently finish your basement? If your pump is too small for the volume of water entering the pit, it will run continuously just to keep up.
