10 Signs That Your Sump Pump is in Need of Repairs
10 Signs That Your Sump Pump Is in Need of Repairs
Winter in Chicago means freezing temperatures, snow, and sleet — and while you’re busy preparing your roof, gutters, and furnace, there’s one basement appliance that can’t be forgotten: your sump pump.
Sump pumps are your first line of defense against basement flooding and water damage, especially during snowmelt or heavy winter rain. If yours isn’t working properly, you could end up with more than just cold feet — you could face ruined flooring, mold growth, and expensive repairs.
Here are 10 warning signs that your sump pump needs repairs — and why now is the time to act.
🔊 1. Strange or Loud Noises
Your sump pump should produce a steady, low hum when operating. If you hear rattling, grinding, or squealing, there could be a mechanical issue with the impeller, fan, or motor. These noises usually signal worn-out parts or debris inside the pump.
⚠️ 2. It Won’t Turn On
If your pump doesn’t activate when water rises in the pit, check the float switch — it might be stuck or broken. If adjusting it doesn’t fix the issue, it could be a failed motor or internal electrical issue that requires a professional diagnosis.
🔁 3. It Runs Constantly
A sump pump that won’t stop running could mean:
- A faulty switch
- An undersized pump
- Improper drainage or constant inflow of water
This issue increases wear on the unit and shortens its lifespan. If your pump never stops, it’s time for an inspection.
🌊 4. It Vibrates Excessively
Excessive vibration often means the impeller has been bent by debris. This part can’t usually be repaired — it needs to be replaced. If not addressed, the imbalance can lead to motor failure.
💤 5. It Sits Too Long Without Use
While it's good news that your sump pump hasn’t had to work recently, infrequent use can lead to unnoticed failures. Test your pump between heavy rains to catch problems early.
🧪 6. Visible Rust or Corrosion
If you notice rust on the pump, it could be due to:
- A corroded battery
- Iron bacteria buildup (which can eventually clog your plumbing)
Rust or discoloration is a sign that your sump pump may be deteriorating and in need of attention.
📆 7. It’s Over 7 Years Old
Sump pumps typically last 7–10 years. If your unit is older, it's more prone to failure — even with good maintenance. Consider replacing it proactively to avoid unexpected breakdowns during winter.
🔌 8. Motor Stops Working
If the motor fails completely, it might be due to:
- A tripped circuit breaker
- Damaged wiring
- A clogged filter or blocked hose
Always have a professional check the electrical system and drainage components before replacing the unit.
💧 9. No Water in the Pit
If your sump pump runs but there’s no water in the pit, it could be an installation error or a disconnect from your drainage system. This is a clear sign something is wrong and a repair or reinstallation may be needed.
🔌 10. It Trips the Circuit Breaker
Your sump pump should not regularly trip your breaker. If it does, the cause might be:
- A short circuit
- A damaged float switch
- Inadequate power supply
This issue could pose a fire hazard and should be evaluated by a licensed plumber right away.
