Sump pumps have an average lifespan of 7 to 10 years but can malfunction and stop working earlier if not maintained properly. With that said, do you check on your sump pump regularly?

Out of sight, out of mind—there’s no shame in answering “no” because it’s normal for homeowners to forget about sump pumps. However, we’re here to remind you that sump pumps need proper installation and TLC to ensure your basement stays dry during the rainy season. 

How long sump pumps last depends on quite a few factors, that we will dive into in this blog. Keep on reading to learn more about these and the common telltale signs for replacement!

Factors Affecting a Sump Pump’s Lifespan

While a sump pump’s average lifespan is 7 to 10 years, the following factors can shorten its service life:

  • Size & Capacity: Size matters when choosing sump pumps for your home because a wrong choice may overwhelm or underwhelm the unit and cause issues.
  • Usage: Overusage or dormancy shortens a sump pump’s lifespan. This device requires regular testing to ensure proper operation.
  • Maintenance: Routine checkup, cleaning, and professional maintenance matter in sump pump lifespan extension.
  • Installation: Incorrect sump pump installation may lead to poor electrical wiring and components management, putting your household at risk.

5 Signs You Need to Replace Your Sump Pump

You must be proactive when it comes to your sump pump’s condition. Instead of waiting for it to reach its predetermined lifespan, it’s a better idea to learn its warning signs. Doing so prevents unexpected breakdowns and a flooded basement

When you notice any of these signs happening to your sump pump, it’s time for a replacement:

1. Constantly Running

A sump pump runs continuously when its switch and float arm components are unresponsive. It occurs when a sump pit shifts or its installation is done incorrectly. This causes the sump pump float switch not to detect water changes, causing the pump to run non-stop. 

Fixing a sump pump’s float switch placement can fix this issue. But if it doesn’t work, you’ll need to replace your unit since it won’t be able to manage water loads effectively.

🛠️ Pro tip: A running sump pump leaves your basement prone to flooding. Instead of keeping water out, the pump brings it in. Call an expert ASAP!

2. Strange Noises and Excessive Vibrations

Sump pumps emit low hums when activated, so hearing loud clangs means trouble. When you hear strange noises, it could mean that the sump pump has busted parts. Its motor usually wears out first due to a failed bearing, but a jammed or damaged impeller could be another reason why the pump is noisy. 

Look out for excessive vibrations or rattling because it could mean a bent or blocked impeller. When this part is compromised, the pump will wobble and shift out of place. 

3. Heavy Rust Buildup

Submersible pumps are made with corrosion-resistant materials, meaning it’s meant to stay underwater without any problems. When you start seeing rust on its surface, it could mean your pump has failing components or a non-toxic bacteria has taken over. 

The metallic gunk can build up and clog your sump pump, making it unreliable and inefficient. We highly suggest calling a plumbing expert to inspect your pump as soon as you start seeing rust on its surface.

4. Frequent On-And-off Cycles

Abnormal power cycling in sump pumps happens when the sump basin is too small to handle the water volume. The pump will alternate from its off and on modes to drain all water, but this operation leads to overwork and sump pump failure.

🛠️ Pro tip: Avoid this issue completely by seeking expert advice from plumbers. They can inspect your basement and determine what sump pump size you need.

5. Stops Working Completely

The last thing you want to see is a flooded basement floor because it means the sump pump has stopped working completely. Pump motor failure is the reason why this issue happens. Wiring problems, clogged drains, and frozen drain pipes cause the motor to short-circuit and shut down. 

A sump pump’s performance relies on routine maintenance done by professionals. They can expertly open submersible and pedestal pumps and see how they can preserve the working conditions. That’s why you should schedule regular check-ups!
