Backwater Valve Installation
Backwater valve installation is a complex job and will require professional services from a licensed plumber. Installing a backwater valve will involve a camera sewer inspection and acquiring local permits.
The backwater valve installation will require breaking through the floor and digging down to the main sewage pipe that takes all the wastewater from your home to the municipal city sewer lines. A piece of the main sewer line will be removed and replaced with the backwater valve – your last line of defense against basement flooding in case the city sewer system backs up.
Backwater Valve Repair
If you already have a backwater valve installed, but are noticing a sewer smell coming from your basement, it might indicate that your sewer backup valve is in need of repair. When your main sewer line backs up, it brings dirty water into your home that can cause that foul odour.
The life expectancy of most backwater valves will vary depending on several factors, such as the quality of materials used, the frequency of maintenance, and the level of usage and stress it will undergo. Generally, a well-maintained backwater valve can last anywhere from 5 to 20 years.
Improper installation, more frequent usage due to heavy rains or flooding, and poor quality materials will mean that your backwater valve needs to be repaired or replaced more frequently.
Backwater Valve Maintenance
Regular maintenance of the backwater valve helps ensure its reliability and effectiveness in preventing sewage backups, protecting property and occupants from potential damage and health hazards.
Proper maintenance of your backwater valve is crucial to keep your system flowing smoothly and free of sewage backup. Maintenance of your backwater valves might be needed if you experience:
- Debris buildup
- Blockages
- Wear and tear from heavy use
- Damage to the seal
- Extreme weather conditions or severe environmental factors
Why Is Backflow Dangerous?
Backflow is a plumbing term that refers to the reverse flow of water or other substances into the water supply system.
This can happen when the normal flow of water is reversed due to changes in pressure, such as a sudden drop in pressure within the water supply system or an increase in pressure in a downstream sewage system. Backflow can pose serious health risks and dangers to homes for several reasons:
Backwater valve installation is a critical component of protecting your home from the dangers of backflow.
How Do Backwater Valves Work?

Put simply, a backwater valve works by allowing flow in one direction while blocking flow in the opposite direction. When water is flowing in the proper direction, away from your home, the flap remains open. When backflow occurs, floaters built into the flap will raise it up and close the pipe to prevent water or debris from entering your home.
Backwater valves are installed within the plumbing system, usually in the sewer line or drain line where it exits the building or home. There are various designs of backwater valves, but they all function on the principle of allowing flow to pass through them in one direction only.
Depending on where you live, your plumbing permit or code may require you to install certain types or styles of backwater valve. It’s important to
When wastewater flows from your home’s plumbing system into the sewer or drainage system, it pushes the flap or gate open, allowing the water to pass through. However, if there is a reverse flow of water or sewage due to a backup or backflow event, the flap or gate automatically closes under the pressure of the incoming flow, preventing it from entering the building.
Like any mechanical device, backwater valves require regular maintenance and inspection to ensure they are functioning correctly. This may involve cleaning the valve to remove any debris or sediment that could interfere with its operation, checking for signs of wear or damage, and testing the valve’s functionality periodically to verify that it opens and closes properly.
