  • What is a backwater valve and how does it work?
    A backwater valve is a plumbing device installed on your main sewer line to prevent sewage from backing up into your home. During heavy rainfall or sewer overload, the valve flap automatically closes to stop water and sewage from flowing backward into your basement. It’s one of the most effective ways to prevent basement flooding in Toronto and the GTA.
  • Do I really need a backwater valve in Toronto?
    Yes if your home has a basement and is connected to the city’s sewer system, you are at risk during heavy storms. The City of Toronto recommends backwater valves to protect your home from sewage backups and even offers a subsidy program to help cover installation costs.
  • How much does a backwater valve installation cost?
    The cost typically ranges from $1,500 to $3,500, depending on your home's plumbing system, accessibility, and permit requirements. The City of Toronto’s Basement Flooding Protection Subsidy Program offers homeowners up to $1,250 back to help offset the cost.
  • How long does the installation take?
    In most cases, backwater valve installation takes one day. Our DrainPro team handles everything from initial inspection to concrete restoration, ensuring a smooth and efficient process with minimal disruption to your home.
  • Is a permit required for backwater valve installation?
    Yes most municipalities, including Toronto, require a plumbing permit before installation. Don’t worry DrainPro takes care of the entire permit process for you, ensuring everything is up to code and subsidy-compliant.
  • How do I maintain a backwater valve?
    You should inspect your backwater valve every 6 months. Open the clear cover and check for debris, wear on the rubber seal, and proper flap movement. DrainPro will show you how to do this during installation and offers maintenance services if needed.
  • Will a backwater valve stop all types of basement flooding?
    A backwater valve protects against sewage backups from city sewer lines. To protect against groundwater or stormwater flooding, you may also need a sump pump or weeping tile system. We offer full basement waterproofing solutions ask us about your options.
  • Can I get help applying for the city rebate program?
    Absolutely. Our team will guide you through the City Basement Flooding Protection Subsidy Program and assist with all necessary paperwork to help you get your rebate quickly and easily.
  • How do I book a free quote for backwater valve installation?
    You can call us at (647) 867-9779 or fill out our online quote form. One of our licensed technicians will visit your home, inspect your system, and provide a detailed estimate with no pressure.
