Lately the only sewer drain problem that a homeowner could not deal with himself/herself has been a failure of the main municipal sewer. This problem has been especially predominant in Toronto, Mississauga and Burlington due to the age, size deficiencies and constant repairs of the old municipal sewer and storm drain pipes. The only way to protect your property from the municipal sewer back up is to install a mainline sewer backwater valve (or also known as back flow prevention device).
Important facts to know about backwater valve installation:
Backwater valve unit is installed at the front foundation wall inside or outside (call us to find out what option suits you!)
Some of the municipalities in Ontario subsidize the installation of the backwater valve unit (for example the city of Toronto, City of Burlington (Halton Region), City of Mississauga (Peel Region)).
Backwater valve installation can lower your home insurance premiums!
When the unit’s floating stopper shuts due to the backup from the street you should stop using your own drain pipes (such as flushing the toilets, using sinks) since the backwater valve unit only protects you from the city’s sewage, but not your own! Be very careful with the unit alarm system – “mainline”, the producer of the backwater valves (the only brand approved for the rebate in Toronto, and the province of Ontario) DOES NOT manufacture any alarm systems for the unit.
