Nowadays, intense rainstorms are becoming a new normal in Ontario due to climate change. During such downpours, property owners in the City of Mississauga have experienced basement flooding caused by sewer backup as well as penetration of water from foundation walls. Fortunately, there is an affordable and simple way to reduce the risk of flood caused by the wastewater or stormwater flowing back to the house: installing a backwater valve.

What is a Backwater Valve Used For?

Because of similar names, a backwater valve is very often confused with a backflow prevention device also called a backflow preventer valve or simply backflow preventer. Unlike the backwater valve that is installed in the basements to safeguard your home from backflow of sewage and flooding, a backflow valve protects the clean water supply line by preventing used water from your property flowing backward into the city’s freshwater system.

The backwater valve is a fairly simple but effective device that is used to prevent the sewer backflow. It allows water from sinks, toilets and tubs to flow out of your home and into the municipal sewer system. At the same time, it has a simple gate that closes shut if dirty sewage begins to back up from the city’s pipes into the basement.

Do I Need a Backwater Valve? 

The requirements for the installation of backwater valves on residential property depend on the municipality. The Region of Peel which consists of three municipalities: the cities of Brampton and Mississauga, and the town of Caledon, warns that the installation of a backwater valve might not be appropriate for all houses. Prior to installing these valves, homeowners are recommended to evaluate their needs and follow the extensive list of guidelines to determine whether a sanitary backwater valve is the right choice for their home. This process may require a significant amount of your time as well as specific knowledge and skills.

What is a Backwater Valve Rebate?

A backwater valve is not only a way to prevent basement flooding but it could also help you to save money.

To assist homeowners who are determined to decrease the possibility of basement flooding, The Peel Region implemented a basement flooding rebates program after seeing an upsurge in the occurrence of floods after heavy rainfalls called “Sanitary Backwater Valve Rebate Program”. Under this program, eligible homeowners in Mississauga can receive up to $700 plumbing rebate for backwater valve installation as a protection measure against flooding and its unpleasant consequences.

In order to successfully claim your subsidy, please follow this step-by-step guide.

  1. Check eligibility

    Confirm your eligibility with the City of Mississauga by calling 905-791-7800, ext. 4409.

  2. Find a professional Mississauga plumber

    A backwater valve is essential by being the defence line against the sewage entering your house. Decide on your own or hire a licensed plumber to assess your situation, check your drainage system and confirm if you require a backwater valve installation for your home.

  3. Hire a plumber to perform a plumbing inspection

    Once you hire a licensed plumber to examine the plumbing system of your home and downspouts, he will perform a thorough inspection of the following aspects:
    – The variety of connections to the sanitary sewer lines. Some of those could be sewer connections, however, there could be connections from sump pumps, weeping tiles, clean water sources or even unknown connections. After investigating all connections, you can request the detailed drawing of all identified connections for your reference.
    – The connection of weeping tiles to the sanitary sewer pipe (lateral) downstream of the valve. If this is the case, there is the possibility that sewage could be pushed into weeping tiles.
    – If it is possible to install a backwater valve directly onto the sewer lateral.
    – If all downspouts are connected to weeping tiles and if there is an option to disconnect them all. If not, could all eavestroughs and downspouts be rerouted and therefore, fully disconnected.
    – To investigate and give recommendations regarding the installation of the additional device (e.g. sump pump, pit) if such needed in order to prevent the possibility of flooding in the future.
    – To provide expert opinion regarding backwater valve installation outside or inside the home. If needed to be outside, should be installed as close as possible to the foundation wall.
    – To ensure that a recommended sanitary backwater valve is ‘normally open type’ and complies with the requirements of Section 7.4.6.4. Protection from the backflow of the Ontario Building Code

  4. Disconnect your downspouts

    Once the initial inspection is done and it is confirmed that a backwater valve can be installed at your property, the first thing you would need to do is to ensure that all downspouts are properly disconnected.

In addition, please check if you are eligible for the Downspout Disconnection Rebate Program (up to $100).
