When there’s substantial precipitation coming down in Toronto, the city’s sewer lines can get overburdened. When this happens, and the pipes are taking in more water than they can handle, the end result, unfortunately, can be water backing up into homes.
One potential method to prevent this water backup is through the use of a backwater valve. The valve is installed on your sanitary and/or storm line in order to prevent water from “back flowing” into your home.
This type of backwater valve features a normally open gate design which makes the continual flow of water possible. The valve allows the free-flow of air through it, yet at the same time in the event of a city sewer backup, the gate floats into the closed position and prevents liquid from backflowing into the home.
The City of Toronto is offering a financial subsidy of up to $3,400 to homeowners of single-family residential homes for the installation of flood protection devices (backwater valves and sump pumps) through the Basement Flooding Protection Subsidy Program.
This subsidy program can help you lower your home’s flooding risk. In consultation with a DrainWorks® plumber – licensed by the City of Toronto – homeowners may determine that a back- water valve on the sanitary sewage and/ or stormwater connection would provide sufficient basement flooding protection. Available subsidy = 80% of the invoiced cost up to a maximum of $1,250 including eligible labour, materials, permit and taxes.
Backwater valves should always be installed by a professional, licensed plumber and should be regularly inspected and maintained.
