Worried about basement flooding or sewer backups?

Whether you’re upgrading an existing system or installing a new one, we ensure fast, compliant, and reliable service.
A backwater valve is a critical component of your home’s plumbing system that prevents raw sewage from backing up into your basement through floor drains and lower-level fixtures. During periods of heavy rainfall, overloaded municipal sewer lines can cause water to reverse direction. Without a valve in place, this can result in contaminated water entering your home—leading to costly damage and serious health hazards.
By installing a backwater valve, homeowners in Toronto can significantly reduce the risk of sewage backflow, especially in flood-prone areas. These devices are designed to automatically close when reverse flow is detected, effectively blocking waste from re-entering your property. It’s a smart, preventative measure that helps protect your basement and your family’s well-being.
A backwater valve is a simple yet effective device that protects your home from sewage backups. It has a built-in drainage slope and a flap. When water flows out of your home, the flap stays open, allowing normal drainage. If water starts to flow back up the pipes, the flap floats up to block the backflow, preventing sewage from entering your home. Once the water pressure normalizes, the flap returns to its open position.
The City of Toronto offers a Basement Flooding Protection Subsidy Program, covering up to 80% of the cost for backwater valve installation or replacement, up to $1,250.
Many Toronto homes, especially those on slopes or flat land, are at risk of sewage backflow due to severe weather and floods. If you’ve experienced any signs of sewage backflow, like water returning through your pipes, installing a backwater valve is essential for health and safety.
Don’t wait for damage to occur; take advantage of the available subsidy for installation. If you’re unsure whether you need a backwater valve, we can assess your water pressure and backflow risk.
