Improve Water Drainage Around Your Home

  • 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.
