What Is a Backwater Valve?
A backwater valve — also known as a sewer backflow preventer or check valve — is a one-way valve installed on your home’s main sewer lateral. It allows wastewater to exit while automatically blocking reverse flow that can force raw sewage back into your basement drains, laundry tubs, or floor sumps. Professional backwater valve installation in St. Catharines safeguards your home from health risks, foul odors, and costly water damage. For long-term protection, pair this system with sump pump installation and sewer camera inspection to keep your drainage system working at its best.

● Lake-Effect Storms: Heavy rain and sudden surges around Lakeside Park can overwhelm municipal sewers.
● Historic Infrastructure: Many Glenridge and Fourth Avenue homes rely on undersized or aging sanitary mains.
● Tourist Demand Seasonal wastewater spikes near the waterfront can trigger backflow into connected residences.

How a Backwater Valve Works
