How to Prevent Common Sump Pump Failures During Heavy Rain

Heavy rain is the worst time for a sump pump to fail. Learn how Westmont, IL homeowners can prevent common sump pump failures and protect their basement from flooding.

Why Sump Pumps Fail When You Need Them Most

When a heavy storm rolls through Westmont, your sump pump becomes one of the most important systems in your home. Its job is simple: collect and remove excess water from around your foundation to prevent basement flooding. But ironically, the time you rely on it most is also when it’s most likely to fail.

Sump pumps that aren’t properly maintained—or systems that aren’t designed for heavy water volume—can quickly become overwhelmed. When that happens, the result is water in your basement, damage to your home, and a major cleanup bill.

The good news? These failures are preventable. Here’s how to keep your sump pump system running strong—especially when the rain won’t stop.

1. Test Your Sump Pump Before the Storm Hits

One of the easiest ways to prevent failure is to test the system in advance.

  • Lift the float manually to ensure the pump turns on.
  • Pour a bucket of water into the sump pit and watch to make sure it activates and discharges properly.
  • If it hesitates, runs without pumping, or makes strange noises—it’s time to service or replace the unit.

Regular testing, especially before Westmont’s spring rains or fall storm season, can catch problems before they become emergencies.

2. Keep the Sump Pit Clean

A clogged sump pit is one of the most common reasons pumps fail. Dirt, gravel, and debris can block the intake or jam the float switch, preventing the pump from turning on or pumping efficiently.

  • Clean the pit every few months
  • Remove any visible sludge or buildup
  • Check the float switch for free movement

A clean pit helps your pump work at full capacity when water levels rise quickly.

3. Check and Maintain the Discharge Line

Even if your pump works perfectly, it won’t help if water can’t exit your home.

  • Make sure the discharge pipe is clear and angled away from the foundation
  • Inspect the pipe for cracks, blockages, or disconnected sections
  • In winter, keep the exterior end of the discharge pipe clear of snow and ice to avoid freezing

For Westmont homes with clay soil, extending the discharge line at least 6 feet away from the house helps reduce pressure and prevent water from cycling right back into the foundation.

4. Install a Battery Backup Pump

Power outages are common during storms—and without power, your sump pump can’t operate. A battery backup sump pump activates automatically if the main pump fails or if the power goes out.

This is one of the smartest investments Westmont homeowners can make. It ensures your home stays protected during the worst weather, when the primary pump is most vulnerable.

Accu-Dry installs reliable backup systems that provide peace of mind during extended storms or blackouts.

5. Don’t Rely on a Single Pump for High-Volume Situations

If your primary pump is undersized—or if you live in an area with a high water table—you may need a more robust system.

Options include:

  • High-capacity sump pumps for larger homes or deeper basements
  • Dual pump systems where two pumps alternate or run together during peak water volume
  • Secondary pumps at different elevations to handle overflow if one unit can’t keep up

During intense Westmont storms, this kind of setup ensures your system can move more water without being overwhelmed.

6. Schedule Routine Maintenance and Inspections

Even the best sump pump will eventually wear down. To avoid surprise failures:

  • Have your pump inspected annually by a professional
  • Replace pumps older than 7–10 years
  • Check for corrosion, frayed cords, or signs of wear
  • Ensure the check valve is working correctly to prevent backflow

Preventive maintenance costs far less than a flooded basement—and gives you peace of mind when the rain starts falling.
