A backwater valve is one of the most effective ways to protect your basement from a sewer backup. When wastewater starts moving the wrong way through your sewer connection, the valve closes to stop it from entering your home. John The Plumber & Drain Cleaning installs, inspects and repairs backwater valves throughout Ottawa.
Whether you want to add protection before a problem happens, need an older valve looked at, or are noticing signs of a drain or sewer problem, our licensed Ottawa plumbers will inspect your setup and explain your options clearly.
A backwater valve sits on the main sewer line leaving your home. As long as wastewater flows out normally, the valve stays open. The moment sewage starts moving in the wrong direction, the valve shuts to block it.
Your drains rely on gravity to carry wastewater downhill into the municipal sewer. A backwater valve adds a mechanical safeguard in case that flow ever reverses.
Under normal conditions, wastewater passes through the open valve on its way to the city sewer.
Heavy rain, sewer blockages and other issues can push wastewater back toward your property.
As reverse flow reaches the valve, the internal flap closes and helps keep sewage from travelling back into your home.

A sewer backup is far more than a messy cleanup. Wastewater in a basement can ruin floors, walls and furniture, and it can leave behind contamination that makes parts of your home unsafe.
Contaminated water can destroy finished basements, flooring, drywall and anything else it touches.
Items kept in the basement are often impossible to salvage after contact with sewage.
A correctly installed valve helps block reverse sewer flow at the point where your home connects to the city sewer.
Combined with a sump pump and good drainage, a backwater valve is a key part of protecting your basement from flooding.
Day to day, the valve does nothing but let wastewater out. Its job starts the instant flow reverses: the flap closes and helps stop wastewater from pushing back into your home.
The City of Ottawa offers financial assistance for eligible flood-protection work through the Residential Protective Plumbing Program. Confirm eligibility and requirements before any work begins.

Eligible Ottawa property owners may qualify for rebates toward the installation of sanitary or storm backwater valves, sump pumps with battery backup and related plumbing permits.
The amount available depends on the type of protective plumbing being installed and the cost of the work.

Here are answers to some of the most common questions Ottawa homeowners ask about backwater valve installation, maintenance, sewer-backup protection and rebate eligibility.
A backwater valve is installed on your home's sewer connection and is designed to help prevent wastewater from flowing backward into the plumbing system during certain sewer-backup conditions.
Not every home has the same sewer-backup risk. Factors such as the home's plumbing layout, basement fixtures, previous backups and the condition of the sewer connection can all matter. A licensed plumber can inspect the setup and explain whether adding a backwater valve makes sense for your property.
A properly installed backwater valve can help reduce the risk of wastewater flowing backward through the building sewer connection, but no single device can guarantee that a property will never experience flooding or drainage problems.
Yes. John The Plumber & Drain Cleaning can inspect existing backwater valves and provide repair or replacement recommendations when the device is damaged, obstructed or no longer operating properly.
Backwater valves should be kept accessible and inspected periodically so the flap and internal components can move freely. If you are unsure about the condition of your valve, our plumbers can inspect it as part of your home's plumbing maintenance.
Yes. The City of Ottawa's Residential Protective Plumbing Program provides financial assistance for certain eligible protective plumbing installations, including qualifying backwater valves. Eligibility, rebate amounts and requirements are determined by the City and should be confirmed before work begins.
Protective plumbing installations that require a City building permit must have the applicable permit in place before the work begins. This is especially important if you plan to apply for assistance through Ottawa's Residential Protective Plumbing Program.
If drains are slow, several fixtures are backing up or wastewater is entering the home, the immediate problem should be diagnosed first.
