What is a Backwater Valve?
When heavy rain overwhelms the municipal system or a blockage occurs, a mainline backwater valve can prevent flooding, keep harmful waste out of your living space, and reduce the risk of costly repairs. The device is placed directly into the sewer lateral at the foot of your basement wall, and allows sewage to flow in only one direction – out of your house.
When sewage begins to move toward your basement, the valve closes to protect your system. If your property has experienced water issues in the past or you’re concerned about aging infrastructure, installing a backflow valve in your basement is a smart, preventative step.

Backwater Valve Installation
Municipal Guidelines and Insurance Considerations
Some municipalities offer rebates or subsidies to help offset backwater valve installation costs, but only if the installation meets their specific requirements. Most require a normally open (or open-port) mainline backwater valve installed directly into the sanitary sewer lateral. This type of sewer backwater valve protects all home plumbing fixtures from potential backup.
In many cases, installing this valve may lower your home insurance premiums or be required for coverage. We’ll help you understand your options and ensure your system meets both local rules and insurance expectations.
Professional Sewer Backwater Valve Installation
The valve should be installed based on the manufacturer’s installation instructions, which have specifications for placement and grading. Proper placement and sewer backwater valve installation are essential – if the valve is installed in the wrong spot relative to other plumbing fixtures on the sanitary lateral, it could be bypassed entirely. This can result in sewer backup pressure, cracks in the basement floor, and eventual flooding.
If your weeping tiles are still connected to the sanitary sewer lateral downstream of the valve, sewage could be pushed back into the tiles. This may cause structural damage to your foundation and lead to infiltration flooding.
Using Your Plumbing After Backwater Valve Installation
If you’re not sure if the valve is closed, check it to be sure – you should be able to see it through the clear, plastic top.
Backwater Valve Repair
You might notice signs like slow drains, sewer odours, or water collecting around basement drains. If anything feels off, we’ll take a look. Our technicians will inspect the valve, clear any blockages, and make the necessary repairs with clear communication every step of the way. If the valve needs more than a quick fix, we’ll talk you through your options so you can decide what’s best for your home
