Backwater Valve Installation
Stop Sewage from Backing Up Where It Doesn’t Belong
When the city sewer system gets overwhelmed — whether from heavy rain, clogged mains, or unexpected blockages — it doesn’t care where the pressure goes.
And without the right protection, that pressure forces sewage straight back into your home.
We’ve seen it happen.
To finished basements. To stored family keepsakes. To homeowners who thought, “It’ll never happen here.”
That’s why at UPR, we don’t wait for backup to happen.
We install backwater valves — the small, powerful devices that block the flood before it starts.
What Is a Backwater Valve?
You might hear it called a backflow preventer or a sewer backup valve — but it all comes down to one thing: control.
This one-way valve is installed in your home’s main sewer line. Under normal conditions, it stays open, letting waste and water flow out. But when pressure from the city line starts pushing back? The valve flap automatically closes — and keeps the mess out.
No sewage. No smell. No disaster.
Why You Need One — Even If It Hasn’t Happened Yet
Most backups happen without warning.
One big storm, one blocked sewer, one overwhelmed main — and suddenly everything below grade is at risk.
Installing a backwater valve helps:
Prevent sewage backups during storms or floods
Block foul odors from creeping into your basement
Bring older homes up to modern code
Qualify you for rebates in Toronto, Mississauga, and Peel
Protect finished basements and valuable storage
Some cities even reimburse part of the installation. And yes — we’ll help you apply.
Our Process: Fast. Professional. No Guesswork.
Whether you’re installing in a new build or retrofitting an older home, we do it cleanly and by the book.
Here’s how it works:
We obtain the proper permits for your area
Our crew carefully excavates to access your sewer main
We install the valve using modern, code-compliant tools
We restore your floor, patch concrete, and leave the space clean
And through it all, we keep you informed — no surprises, no shortcuts, no stress.
Maintenance Matters — Here’s Why
Backwater valves are built to protect — but they’re not “set it and forget it.”
Over time, debris, grease, or even sediment buildup can prevent the flap from sealing properly. That means your defense could fail just when you need it most.
That’s why UPR offers regular maintenance plans to:
Inspect and test the valve
Clean and flush the chamber
Ensure smooth operation before every storm season
Catch issues before they cause damage
Think of it like an insurance policy that actually gets checked.
Smell Something Off?
If you’re getting sewer odors in the basement, your system is telling you something — and it’s not good.
Let us inspect your line and give you real answers. If a backwater valve is the right fix, we’ll tell you. If it’s something else? We’ll show you exactly what it is — no pressure, just facts.
