- Extend gutter downspouts at least 10 feet away from your foundation.
- Clear your gutters twice a year to avoid overflow.
- Ensure your yard slopes away from the house to direct water outward.
- Keep storm sewer connections and outdoor drain lines clear.

Install Backflow Prevention Devices
Anti-backflow valves reduce the risk of sewage backing up into your basement. Options include:
- Check-valve: Allows flow out but blocks reverse sewage flow.
- Gate-valve: Manually closes to seal off water flow during a surge.
Ask a licensed plumber which type is right for your home and plumbing setup.
Maintain and Test Your Sump Pump System
- Install a sump pump to remove groundwater around your basement.
- Choose from single or dual-level systems depending on risk level.
- Test your pump monthly and inspect for signs of wear or clogs.
- Use a backup battery or generator in case of power outages.
- Never connect the pump outlet to your main plumbing line.
Protect Basement Belongings from Water Damage
- Keep personal items and storage boxes elevated off the floor.
- Use shelving units and avoid placing furniture near floor drains.
- Place furniture on casters or shims to minimize water contact.
It’s also a good idea to have a water sensor or alarm system that alerts you to leaks or flooding in real-time.
Review Your Homeowners Insurance Policy
Standard homeowners policies may not cover all types of sewer and drain backup damage. Talk to a local insurance agent to:
- Understand what’s included in your current policy.
- Consider adding sewer or water backup endorsements if needed.
