Protect Your Home from Sewage Backups
Proper backwater valve installation provides essential defence against sewer overflow, keeping raw sewage out of your home.
Backwater Valve: A New Layer Of Water Security
In Nova Scotia, where heavy rain and unpredictable weather are part of life, protecting your home from sewer backflow isn’t optional — it’s essential.
At Mechanical Flood Protection, we specialize in backwater valve installation, helping homeowners across the province prevent the unsanitary and costly damage caused by sewer overflows. Inspired by flood prevention systems used in major cities with combined sewer systems, our solutions add a critical layer of defence, keeping your home dry, safe, and sewage-free.
What is a Backwater Valve?
A backwater valve is a critical flood protection device that prevents sewage from flowing back into your home during heavy rain, rapid snowmelt, or storm surges.
It contains an internal “flapper” that automatically closes when it detects backflow, blocking sewage from entering. Once the risk passes, the valve reopens to allow normal wastewater to exit your home safely.
How Does A Sewer
Backflow Valve Work?
The operation of a sewer backflow valve is simple but highly effective. When heavy rain or a sewer system overloadoccurs, the valve’s internal flapper automatically closes, blocking sewage from reversing into your home’s plumbing.
The backward pressure itself triggers this proactive response — no manual action required. Once the pressure normalizes, the flapper reopens, allowing wastewater from your home to flow out as usual, keeping your living space protected and sanitary.
Our Sewer Backwater Valve Installation Package
SEWER FLOOD PROTECTION
- Stops sewage backflow during heavy rain
- Prevents contaminated water from entering home
- Increases property value with added protection

Benefits of Backwater Valve Installation
Installing a backwater valve is more than just a preventive measure — it's a smart investment in the health, safety, and long-term value of your property. Here are the key benefits:
Cost Savings
Avoid the high costs of sewage cleanup and restoration — often ranging between $2,000 & $10,000.
A backwater valve helps you steer clear of these unexpected and expensive repairs.
Damage Prevention
Prevent flooding caused by sewage backups and heavy water flow. A properly installed valve keeps your basement, belongings, and home interior safe from unsanitary and destructive water damage.
Increased Property Value
Homes equipped with advanced flood protection systems like a backwater valve are significantly more attractive to potential buyers and may ultimately command a higher market value.
Peace of Mind
Enjoy the confidence of knowing your home is equipped to automatically prevent sewer backflow, providing 24/7 protection — especially during storms or infrastructure overloads.

5 stars – Outstanding work from Jake and his entire team
Jake and his team (Jared, Luke, “Diddy/Daddy”) did a wonderful job on my recent basement plumbing and flood‑protection project. Jake wears many hats – CEO, estimator, communicator, and plumber – and he does all of them extremely well. His quote was detailed and clear, and he responded to what felt like a million questions from me quickly and with great patience. He addressed my doubts professionally, walked me through every step, and always took time to explain options.
What impressed me most was his attention to detail and his commitment to doing the work to code. Jake and his wife Jacqui clearly care about quality and customer satisfaction, and it shows in how they run Mechanical Flood Protection. Jake is very active on social media and it’s obvious he values his reputation – and he earns it.
Of course, he couldn’t do it without an amazing team. Everyone on site was polite, respectful, and professional. They know what they’re doing, they work well both independently and together, and they were punctual every day. They did their best to protect my property during the work; for example, Luke even cleaned dust off my walls as soon as he could.
It was also a pleasant surprise to see Jacqui, the CEO, come to the worksite. When I struggled to follow some of the technical explanations, she put things into plain language so I could truly understand. Jake also took my insurance needs seriously and worked closely with me so that the final setup would help me get better coverage and peace of mind.
Another big plus: Jake recommended a carpenter, Devon, to handle the drywall and flooring after the plumbing. Devon came the very next day, rearranged a larger project to fit me in, and agreed to restore my basement as soon as possible. That was a huge relief, because plumbers usually don’t put everything back together after they open walls and floors. I even suggested to Jake that teaming up with carpenters like this is a great way to bring basements fully back to normal.
Overall, I’m extremely happy with the work and the experience. I highly recommend Jake, Jacqui, and the whole Mechanical Flood Protection team – 5 out of 5!

I had a stairwell & interior drainage system installed in a small apartment building for the Affordable Housing Association of Nova Scotia.
Jake & staff were great during the project. They didn't oversell while quoting and used high quality components. The system has been working great since installed (1 season in & no more flooding!!) Thanks!

Jakes' team recently installed their Sump Pump system at our house. We found the installation teams work to be very professional. They were happy to answer any questions we had. Overall we are very pleased with this new system, our basement is drier and we no longer worry about the basement flooding.

Jake and his guys are fantastic. Nothing but good things to say. I would recommend anyone pay a bit more than to get the work done by a less experienced company. I did, and Jake had to come fix their work. He has the full package, and does things right. Other companies who have done work for me cut a lot of corners and It cost me more money in the long run. We will be using Jake for all of our waterproofing needs moving forward.

From start to finish Mechanical Flood Protection was one of the most professional and expedient businesses we've worked with. They were quickly able to determine a solution to our problem and in less than a week from our initial quote we had an installation date for the sump pump we needed. Their team worked diligently throughout the day and installed a clean and minimally invasive system in our home, walking us through every step of the process. They left the site cleaner than when they entered to boot! Would highly recommend their services.

We recently hired Mechanical Flood Protection to upgrade the drainage system and sump pump in my mom’s older home, and we had a great experience.
Because my mom isn’t very comfortable speaking English, I communicated with Jake Allemang by text and phone before the project started. He was always responsive, patient, and clear in explaining everything to me.
When the team arrived onsite, they were extremely professional and took the time to carefully explain the issues and solutions to my mom in person, while also keeping me updated to make sure there were no communication gaps. That meant a lot to us.
They even worked over the weekend to avoid disturbing the Airbnb guests staying at the house, which shows how considerate and customer-focused they are.
The whole team was friendly, warm, and highly professional. They responded quickly, offered different upgrade options, and tailored the solution to meet the specific needs of the house.
I highly recommend Mechanical Flood Protection to anyone looking for reliable and thoughtful service.

Our 75 year old home had a pump less pit that drained underground and basement moats that were an eye sore and no longer able to handle today's rainfall events. After a year of trying to remedy the water ourselves, we met Jake at our local home show and we knew immediately he could help us. First impressions were knowledge, honesty, no sales tactics and cares about clients. His quote after visiting our home proved the validity of our impressions and the price was unmatchable. The quality of work was outstanding. After completion, Jake called and asked if we were 100 percent happy which we are and we are confident our basement will be forever dry. Sump pump is top quality and the plumbing work is completed by Jake. Warranty and annual inspection is also included which is unbeatable. Thanks Jake and team for your values of honesty and integrity.

I had a great experience with Jake and his team at Mechanical Flood Protection here in Dartmouth, Nova Scotia. I first connected with Jake after coming across one of his social media videos where he was educating homeowners about flood protection. From that first inquiry through to our initial discovery call, he was thorough, professional, and a really clear communicator. He took the time to understand the challenges I was dealing with and what the right outcome looked like for me. On the day of the work, Jake and his team showed up on time and kept me in the loop as things progressed. When they wrapped up, it was obvious they take pride in their work. Everything was clean, well finished, and thoughtfully buttoned up. I would absolutely recommend these guys. Great service like this can be rare these days, and it was a breath of fresh air. Thanks again, Jake.

I couldn’t be happier with the service and product I received from Jake and his crew. From the very first consultation, he and his team were professional, knowledgeable, and genuinely committed to helping me protect my property. He explained the mechanical flood system in detail, answered all of my questions, and customized a solution that perfectly fit my needs.
Installation was smooth and efficient, with minimal disruption. The system itself is incredibly well-engineered—durable, reliable, and designed with safety and peace of mind in mind.
What sets this company apart is not just their technology but their dedication to customer care. Jake provided clear guidance on maintenance and even provided an extension for one of my downspouts from my gutters to help prevent future issues free of charge! It’s rare to find a business that combines innovation with such a high level of service.
I highly recommend this company to anyone looking for a dependable flood protection solution. Their system is an investment in security, and their professionalism makes the entire process stress-free.

Jake and team are quite simply some of the best plumbers and flood protection in NS. I have worked with a bunch as a contractor; and Jake is always the one I try to book in for my clients. Now - unless there's a really good reason - I won't bring in a different plumber. For the egos who might get bruised thinking "hey I'm a good plumber... How can Jay say Jake is one of the best..." Truth is - he is. Once I explain what I get from Jake and my expectations on a project - I haven't had anyone meet the bar set by Jake. My clients rave about him. Price is decent - on a scale of 1 - 10 - 10 being the highest and 1 - you will need a pro to come fix what they did - Jake is around a 6-7 on pricing and worth every penny. If you want the project done perfectly, when he says he will do it he does... Book Jake. Trust me the quality and professionalism are worth gold. DM me for a reference or pictures if needed.

Working with Mechanical Flood Protection was a fantastic experience from start to finish. Jake and his team were very professional with excellent communication throughout the process. Jake thoroughly explained the scope of the work to us, made sure we understood how the installed system works, completed the work on time and left the basement tidy and clean. It looks better than when they arrived. The job required heavy work during two of the hottest days of the summer and we appreciate the extra commitment it took Jake and Jared to work in those conditions. They were very well organized, arrived on time, efficient and very easy and pleasant to interact with. Everything we were hoping for with this project. We highly recommend Jake and his team at Mechanical Flood Protection.

Jake at Mechanical Flood Protection is probably the most conscientious professional I have met. He installs the highest quality equipment available, and he stands behind his work. And with his personable approach he has no trouble explaining in detail exactly what he is doing, and why.
As a Radon Mitigation contractor that sometimes is faced with water problems in basements, I feel confident that no matter how complex or difficult those water problems may be Jake and his team can solve them - and I have no problem at all in recommending them to anyone in the province.

I recently had a new sump pump installed by Mechanical Flood Protection, and I can’t say enough about the outstanding service they provided. From the first conversation to the final touches, their team was prompt, professional, and incredibly efficient. They communicated clearly every step of the way, making the entire process smooth and stress-free.
What truly set them apart was the extra mile they went—taking care of additional repairs at no added cost. That level of care and integrity is rare, and it didn’t go unnoticed. As someone who’s run their own business, I deeply understand the value of a sincere testimonial. This one is well-earned.
If you’re in need of trustworthy, high-quality work with a personal touch, I wholeheartedly recommend Mechanical Flood Protection.

Though we have been managing with a stand up pump, any time it rained or got a bit windy we were worried about power failures and floods. We’ve been talking about upgrading but weren’t sure where to start so we were happy to meet Jake and Jacqui at the Home Show. The install went great - no mess left behind and the work was well done with quality equipment. Billing was easy, no extra charges or ‘up-selling’. We would highly recommend Mechanical Flood Protection.

It was a pleasure to work with such a professional and dedicated expert as Jake. Our case was quite complex, but Jake was extremely patient and thorough, eager to fully comprehend what was going on in our basement. He gradually found a solution, taking into account both the effectiveness and the costlessness. Our basement is now properly protected against flooding by a modern and upgraded system (sump pump, inside drain). He communicates clearly and explains everything. His entire team is also fantastic. His professionalism made a great difference when choosing his company. We will 100% recommend his work. We are very impressed and grateful. Thanks again, Jake! Florence and Pierre

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.
