Ottawa-approved Backwater Valves
A sewer backup can cause tens of thousands of dollars in damage to your home – not to mention the yuck factor. Thankfully there’s a simple, cost-effective device that can ensure you never have to face a basement full of sewage: a backwater valve.
This clever device allows one-way flow from your home to the sewer. As soon as backflow is detected, it closes up and keeps your home safe.
They’re so effective that the City of Ottawa now has a bylaw requiring all new homes have one installed. They also provide rebates for retrofits.

We Use Mainline Backwater Valves for Best Results
Mainline is North America’s most trusted brands when it comes to backwater valves. The innovative, multi-award winning Mainline Fullport design was the first backwater valve design to use the “normally open” gate concept. It can be installed on both storm and sewage lines (if your home was built before the 1960s they’re probably combined).

Backwater Valve FAQ
Sometimes the city sewer system can become clogged. Until people in the neighbourhood realize the problem, they will keep flushing toilets and running taps. When that happens the water will start to back up into any empty pipe it can find, including the pipes that provide drainage from the nearby homes. Any pipe without a backwater valve will allow sewage to rise up and flood the basement.
Backwater valves are recommended for any home, even homes on higher ground. A sewer backup can happen even if your home is at the top of a hill: it’s caused by a clog, not groundwater flooding.
Having a backwater valve installed will help protect your home against sewer surges.
Probably – if your home was built before the 1960s. In these homes, the sewer lines are often still tied into storm drain lines. If your home is in these areas, the backwater valve will protect your home. Homes in newer neighbourhoods, however, have separate storm and sewage lines, so you may need to install a backwater prevention device on the storm water line as well.
Yes – before you finish your basement or renovate. Installation of backwater valves is best done in unfinished basements because it requires a trench about 2 – 3 feet long to be dug in your home to provide room for the device. Depending on the pipe layout and construction of your home, the trench may need to be larger.
Backwater valves will protect your from blockages located outside your home – not inside your home.
Backwater valves cannot stop waste being added by the home owners. For example, if the backwater valve has been floated due to high sewage levels outside the home, any waste that is flushed in the home will cause a backup within the homes waste pipes as there is nowhere for it to go.
