If your home has a basement, chances are you’ve heard of a sump pump—or already rely on one. These essential devices are your first line of defense against water intrusion and flooding. But here’s the critical question: Do sump pumps fail? Unfortunately, the answer is yes, and when they do, the consequences can be costly.

In this article, we’ll explore the most common causes of sump pump failure, how you can prevent them, and why proactive maintenance is key to protecting your basement. If you’re a homeowner in Southeastern Pennsylvania, this guide is especially for you.

What Is a Sump Pump and Why Do You Need One?

A sump pump is a submersible device installed in a sump pit at the lowest point of your basement or crawlspace. Its job is to automatically pump out water that accumulates in the pit, preventing basement flooding during heavy rains, snowmelt, or rising groundwater.

A functioning sump pump protects your home from:

• Water damage
• Mold and mildew growth
• Foundation deterioration
• Ruined belongings and furniture

But what happens when your sump pump doesn’t do its job?

Yes, Sump Pumps Can Fail — Here’s Why

Sump pumps can fail for several reasons, and they often go unnoticed until it’s too late. Below are the most common causes of failure:

1. Power Failure

During severe storms—when you need your sump pump most—your home may lose power. Unless you have a backup system (like a battery-powered or water-powered backup pump), your main unit won’t function.

2. Lack of Maintenance

Just like any other piece of equipment, sump pumps need regular maintenance. Clogged pumps, dirty float switches, and blocked discharge lines can all lead to system failure.

3. Old Age

Most sump pumps have a lifespan of 7–10 years. As they age, parts wear out, motors weaken, and performance degrades. If your pump is nearing the end of its lifespan, it’s time to plan a replacement.

4. Improper Installation

If a sump pump is installed incorrectly—wrong pit size, poor drainage design, or a misaligned float switch—it can fail when it matters most.

5. Overwhelmed Pump

If your area receives unusually heavy rainfall (like July storms in Southeastern PA), your pump may not be powerful enough to keep up. In some cases, a secondary pump or upgraded system may be necessary.

6. Frozen or Clogged Discharge Lines

If the water your pump pushes out has nowhere to go—due to a frozen line, debris, or blockage—it will back up into your basement.

How to Prevent Sump Pump Failure

Prevention starts with awareness and routine care. Here are some practical steps you can take:

Test Your Pump Regularly

At least every 3 months, pour a bucket of water into the sump pit. Your pump should turn on, discharge the water, and shut off properly.

Schedule Annual Inspections

Have a waterproofing specialist inspect your sump pump each year—ideally before spring or during the rainy summer months.

Install a Battery Backup System

Power outages happen. A backup battery can keep your pump running even during extended blackouts, giving you peace of mind.

Keep Discharge Lines Clear

Make sure your discharge pipe is clear of dirt, mulch, or ice. Adding a sump pump check valve also helps prevent water from flowing backward.

Upgrade When Necessary

If your pump is more than 7 years old or can’t keep up with heavy storms, it may be time for a replacement or secondary unit.
