Don’t Let Fall Showers Flood Your Basement: The Sump Pump Checklist

September in West Michigan is a season of transition. As we trade beach days along Lake Michigan for crisp autumn air and cozy sweaters, our weather takes a noticeable shift. While most homeowners are focused on raking leaves and getting ready for furnace season, there’s another critical fall event to prepare for: heavy, sustained autumn rainfall.
After sitting mostly dormant through the drier summer months, your sump pump is about to be called back into action. If it fails during a heavy September downpour, you could wake up to a flooded basement, ruined belongings, and thousands of dollars in water damage.

Before the fall storms roll through Grand Rapids and the surrounding communities, take 10 minutes to run through this essential September Sump Pump Checklist.

1. The “Bucket Test”: Is Your Pump Actually Working?

Just because your sump pump was working last spring doesn’t mean it’s ready for fall. Electrical components can fail, float switches can stick, and motors can freeze after sitting quiet all summer.

How to perform a quick bucket test:

  1. Locate your sump pit in the basement or crawlspace.
  2. Slowly pour a 5-gallon bucket of water directly into the pit.
  3. Watch the float switch—as the water level rises, the float should rise naturally and trigger the pump to turn on.
  4. The pump should quickly discharge the water outside and shut itself off smoothly once the pit is empty.

If the pump doesn’t turn on, makes a grinding noise, or runs continuously without pumping water out, it’s time to call in a professional plumber right away.

2. Clear Out Debris & Clean the Screen

Over time, sediment, dirt, gravel, and small debris can wash into your sump pit. If this debris gets sucked into the pump’s intake screen, it can clog the impeller, overheat the motor, or jam the float switch in the “off” position.

  • Disconnect the power to the pump before reaching into the pit.
  • Remove any visible debris, dirt, or rocks from the bottom of the pit.
  • Inspect and gently clean the intake screen at the base of the pump.
  • Check the exterior discharge pipe outside your home to ensure leaves, mulch, or dirt aren’t blocking the exit point where water flows out.

3. The Absolute Necessity: A Battery Backup Sump Pump

West Michigan fall storms frequently bring strong wind gusts, falling tree branches, and sudden power outages.

Here’s the catch: Standard sump pumps run on electricity. If a heavy autumn thunderstorm knocks out power to your Grand Rapids neighborhood, your primary sump pump stops working at the exact moment you need it most. Water will continue filling your pit, with nowhere left to go except across your basement floor.

Installing a battery backup sump pump system provides crucial protection:

  • Automatic Kick-In: If the primary power goes out—or if your main pump fails mechanically—the battery backup automatically takes over.
  • Pumping Power During Storms: High-capacity battery backup systems can pump thousands of gallons of water on a single charge, keeping your basement completely dry until main power is restored.
