Residents can help prevent basement flooding with a few simple changes around the home:

• Seal window wells and cracks in floors, walls and the foundation.
• Slope ground away from the foundation to allow rainwater to flow away from the home.
• Direct downspouts from eaves troughs away from the foundation (minimum of 1.2 metres) or to a rain barrel.
• Disconnect downspouts from the sewer system or foundation drains.
• Ensure foundation drains direct water to the storm sewer or sump pump. Foundation drains should not be connected to the sanitary sewer.
• Ensure the sump pump is connected to the storm sewer or discharges to the ground at least 1.2 metres from the foundation.
• Install protective plumbing devices, such as backwater valves which protect against surcharging in City sewers. The City’s Residential Protective Plumbing Program offer rebates to qualified homeowners.
• Maintain existing protective plumbing devices according to the manufacturer’s instructions. A protective plumbing device should be maintained periodically or before a forecasted heavy rainfall to ensure it is free of debris, functioning properly and that cleanout caps and access covers are firmly secured.
  • In older homes, especially those with cast iron pipes, additional maintenance may be required, as rust can accumulate at the hinge and prevent proper closure of the backwater valve during a surcharge event.
  • For more tips on backwater valve maintenance, refer to a video on Backwater Valve Maintenance from the Institute for Catastrophic Loss Reduction.
