A failing sewer ejector pump is typically caused by a jammed impeller, a burnt-out motor, or a malfunctioning float switch. If you have a basement bathroom or laundry room in the Hanover area, addressing these issues immediately is essential to prevent raw sewage from backing up into your home.

Top 4 Signs Your Sewer Ejector Pump Needs Repair
Unlike a standard gravity-fed plumbing system, a basement bathroom relies entirely on your ejector pump to push wastewater up and out to the main sewer line. When the system struggles, it usually gives you a few clear warning signs:
- Foul Sewage Odors: If your basement suddenly smells like raw sewage, the pump’s seal may be broken, or the system is failing to properly vent and move waste out of the basin.
- Constant Cycling: A pump that turns on and off continuously is usually dealing with a broken float switch or a failing check valve. This forces wastewater to flow back into the pit, making the motor work twice as hard.
- Loud or Unusual Noises: While a low hum is normal, grinding, rattling, or screeching sounds indicate a mechanical failure. Debris or hard objects might be jammed inside the impeller, or the motor bearings are wearing out.
- Old Age: Most high-quality sewer pumps last between 7 and 10 years. If your unit is older than a decade and struggling to keep up with daily water usage, an upgrade is much safer than waiting for a complete breakdown.
When to Call a Hanover Sewer Pump Professional
