Does your home need a backwater valve installed?

Every home is at risk of basement flooding, even if there has never been a flooding incident. If your home is newly constructed it should already have a backwater valve as it is now required by law on all new homes.

Help protect yourself against basement flooding

As the city continues to grow at a rapid pace, the sewer system remains old and can no longer keep up with today’s demand.

The City of Toronto is working to make improvements to its underground sewers but these improvements are slow and cannot protect a home from basement flooding.

The City of Toronto acknowledges that all home owners need to install a backwater valve to protect their home from flooding.

During a rainfall, Toronto sewers can become overloaded causing city sewage to backup and flood your house. Even if you have had your Sewers replaced, if you do not have a Backwater Valve installed on your mainline drain you are at serious risk of flooding.

It is important that you take immediate action and reduce your risk of basement flooding.

The City offers homeowners a subsidy of up to $1,250.00 for the installation of a Backwater Valve on your Main Sewer line by a licensed Plumbing Company like Priority Plumbing and Drains.
