What Is a Backflow Prevention Device?

A backflow prevention device, also known as a backwater valve, is installed on your main sewer line to stop sewage and stormwater from flowing back into your home.

When municipal sewer systems become overloaded during heavy rain, blockages or sudden pressure changes, wastewater can push back toward your property. Without a backwater valve, raw sewage can surge through floor drains, sinks, toilets and showers, flooding your basement.

A properly installed backflow prevention device acts as a one way gate. It blocks contaminated water from entering your home while still allowing your household wastewater to flow out safely.

Why Backflow Prevention Is Essential

Without backflow protection you risk:

• Basement flooding from sewage entering your home during storms or sewer backups
• Health hazards from exposure to harmful bacteria, mold and contaminants
• Property damage to drywall, flooring, furniture and valuables
• Expensive repairs, with restoration costs that can reach tens of thousands of dollars

Installing a backwater valve is one of the most effective and affordable ways to protect your home and basement, and in many cases it is required for new construction and major plumbing renovations.
