How to Prevent Basement Flooding During Heavy Fall Rains

As Michigan heads into the rainy season, one of the biggest concerns for homeowners is basement flooding. Heavy fall storms and clogged drainage systems can lead to costly water damage, mold growth, and ruined belongings. The good news? With proper preparation and maintenance, you can prevent basement flooding before it starts.

1. Inspect and Maintain Your Sump Pump

Your sump pump is your first line of defense against flooding. It automatically removes excess water from your basement during heavy rain. However, if it’s not working properly, you could be facing a major mess.

  • Test your sump pump by pouring water into the pit to make sure it activates.
  • Clean debris from the pit and discharge line.
  • If your pump is over 7 years old, consider replacement.
  • Add a battery backup system to protect against power outages.

Putman & Son’s Plumbing recommends testing your sump pump each season—especially before fall storms hit.

2. Clean Gutters and Downspouts

Fallen leaves are beautiful, but they wreak havoc on gutters. When gutters or downspouts get clogged, water overflows and seeps near your foundation. This increases hydrostatic pressure, which can lead to cracks and basement leaks.
Be sure to:

  • Clean gutters at least twice per season.
  • Extend downspouts 6–10 feet away from your home.
  • Consider installing gutter guards to reduce buildup.

3. Seal Foundation Cracks

Even small cracks in your foundation walls or floors can allow water to sneak in. Check for visible cracks and seal them with waterproof epoxy or hydraulic cement. For larger issues, schedule a professional inspection.

4. Install or Test Backflow Prevention Valves

If you experience frequent flooding, installing a backflow prevention valve on your main sewer line can stop sewage from backing up into your basement. These valves automatically close during heavy rain events, protecting your home from contamination.

5. Schedule a Professional Drain Cleaning

Over time, debris, grease, and sediment can build up in your drain lines, slowing water flow. A professional hydro jetting service clears these blockages safely and efficiently—keeping your system flowing freely all season long.

Stay Flood-Free This Fall

Preventing basement flooding is all about proactive maintenance. A quick inspection and a few preventive steps can save thousands in water damage.
