What Is a Backwater Valve and Why Do You Need One?

A backwater valve is your first line of defense. This simple but effective device automatically closes when water tries to flow back toward your home, stopping sewage backups before they start.

​A backwater valve is installed on your main sewer line. Under normal conditions, it stays open to let wastewater flow out to the city sewer. But during a flood or sewer overload, it senses reverse flow and automatically closes a flap inside, sealing your home off from the city's backed-up sewer lines.

This is essential flood protection for any Toronto-area home with a basement. Without a backwater valve, your drains, toilets, tubs, and basement floor drains can all become entry points for raw sewage.

I had no idea how important a backwater valve was until a storm flooded our basement. I called DrainPro, and they explained everything clearly and helped us apply for the city rebate. The install was quick, clean, and professional. Now we feel protected every time it rains.
