Expert Backwater Valve Installation, Nova Scotia & Beyond

Shield Your Home –  The Essential Defense Against Sewer Overflow

A New Layer Of Water Security

In regions like Nova Scotia, where weather patterns can be unpredictable, safeguarding your home against sewer backflow is crucial. Mechanical Flood Protection specializes in the installation of sewer backwater valves, offering homeowners protection against the unsanitary and costly consequences of sewer overflow. Inspired by flood protection solutions employed in cities with combined sewer systems, we bring critical defense mechanisms to your home, ensuring it will stay dry, safe, and sewage-free.

What is a Backwater Valve?

A backwater valve is an essential component of modern plumbing systems, designed to prevent the backward flow of sewage into your home during the overflow of water caused by heavy rainfall, rapid snowmelt, or a storm surge. It features an internal mechanism known as the “flapper,” which automatically closes in response to backflow, protecting your property from the hazards of sewer overflow. Once the risk subsides, the valve reopens, allowing normal wastewater discharge from your home into the sewer.

How Does A Sewer
Backflow Valve Work?

The operation of a sewer back-flow valve is straightforward yet effective. During periods of heavy rainfall or sewer system overload, the valve’s flapper closes, preventing sewage from reversing into your home’s plumbing. This proactive closure is triggered by the backward flow itself, ensuring immediate response to potential threats. After the overflow, a change in pressure automatically reopens the flapper, resuming normal flow from your home to the sewer, safeguarding your living space without any manual intervention.

The knowledge Jake has with flood protection is second to none. The system he’s built is the Cadillac of flood protection systems and a very great price for what you’re getting! My companies done quite a few flood renovations since the massive floods last year and every one has gotten his system installed. The peace of mind you get knowing your basement is safe is worth its weight in gold! 10/10 cannot recommend more!!

There is no better feeling than knowing your home is protected! We have lived rurally for over 25 years. We've had our share of flooded basements, ruined equipment and ruined personal belongings. When I learned about the system the Mechanical Flood Protection team was installing, I knew we needed it! The piece of mind knowing that we now have a back system as well as a monitoring system that alerts us to any issues is amazing!

After my basement flooded I discovered the Mechanical Flood Protection system and decided to explore further. Jake was very professional and answered all my questions so that I could understand things. The battery backup for the system in case of power outage was a great contributing factor in my decision to get the system. The installation was quick and clean, and Jake showed me how to add the app to my phone explaining how to monitor the system 24/7. The comfort I have knowing this system will help protect my home from future flooding (without or without power) is amazing, just like Jake and his team. I highly recommend this system to protect a home, especially with the way the climate is changing.

Sewer Back-Up Protection FAQ

If you live in an area prone to heavy rainfall, near a water body, or in a region with a combined sewer system, installing a backwater valve is highly recommended. It’s an essential defense mechanism that protects your basement and property from sewage backflow during sewer overflows, safeguarding your home from potential health hazards and costly damages.

The legal requirement for backwater valve installation varies by location. Some municipalities, especially those prone to flooding or with combined sewer systems, mandate the installation of backwater valves in new constructions and may offer incentives for retrofitting existing homes. Check with your local building codes or consult with Mechanical Flood Protection to understand the regulations applicable in your area.

The installation of a backwater valve typically takes between 2 to 8 hours. The duration depends on the accessibility of your home’s drainpipes and the complexity of the installation. Mechanical Flood Protection ensures a swift and efficient installation process, minimizing any disruption to your daily routine.

If you suspect your backwater valve is not functioning correctly, it’s important to act quickly to avoid potential sewage backup. First, check if the valve is accessible and try to see if there is any visible blockage. However, for safety and to prevent damage, we recommend contacting Mechanical Flood Protection immediately. Our experts can conduct a thorough inspection, perform necessary maintenance or repairs, and ensure your valve is in optimal working condition.
