Some valve that is not taken care of might just break at the time when the situation requires it the most.
Through this guide, the author has covered the backwater valve maintenance checklist that every Canadian homeowner needs to adhere to to ensure that the property is not affected by the expensive sewer backup.
What Is a Backwater Valve?
A backwater valve refers to a safety measure that is installed in your sewage.
Its task is very straightforward but of high importance: it enables the wastewater to go out of the house and does not permit sewage to go back in.
Wastewater can be sent in reverse when sewer systems of municipalities become overloaded because of storms or obstructions.
This sewage could find its way in your basement through drain pipes without a valve.
Well performing backwater valves for sewer systems are automatic and close when back flow pressure is observed.
This will avoid the entry of polluted water into the house.
The use of these valves has been encouraged by most of the municipalities in Ontario, like City of Mississauga, Oakville, Hamilton and Niagara, to secure residential properties.
Why Backwater Valve Maintenance Matters
Installing backwater valve is a clever move towards flood prevention and it is maintenance that makes them dependable.
With time, there is a possibility of the deposition of debris, grease and sediment in the valve.
In case of the impossibility of the proper closing of the valve flap, the sewage might still get into the home.
Regular maintenance provides several benefits:
- Prevents basement flooding caused by sewer backups
- Extends the lifespan of your plumbing system
- Reduces the need for costly Plumbing Repair services
- Keeps the backflow valve sewer system operating correctly
- Helps homeowners avoid emergency plumbing situations
For homeowners in older neighborhoods, maintenance becomes even more important because aging sewer systems are more prone to backup issues.

Backwater Valve Maintenance Checklist for Homeowners
Homeowners can follow this simple checklist to ensure their valve stays in good condition.
1. Locate the Valve Access Cover
The majority of backwater valve sewer systems of sewage systems have an access cover within the basement floor.
The access point can be a little larger or a little smaller depending on the type of backwater valve installed in your home.
Always ensure that the cover is always easy to access.
Make sure not to place furniture, flooring, or storage over it.
Inspection and cleaning are much easier by seizing the opportunity easily.
2. Clean Debris from the Valve
Dirt, grease, residue in soap and small particles may be accumulated in the valve chamber over time.
When there is an accumulation of debris around the mechanism, this can even result in the inability of the valve to close.
The cleaning is done on a regular basis to maintain the performance of the both backwater valve types as well as other back flow valves that are utilized in residential sewer protection systems.
Cautiously wipe off the cover and scrape off any debris.
This guarantees that the valve flap has free movement.
Do not use other harsh chemicals that may destroy the valve parts.
3. Check the Valve Flap Movement
The flap on the inside of the sewage back flow valve should be able to open and close without any problems.
In the event of a sewer overflow, wastewater can leak into the house in case the flap becomes stuck or does not close fully.
A rapid check will make the mechanism operational.
4. Inspect for Blockages in the Sewer Line
Unnecessary pressure on the valve may be created by a blocked sewer line.
The symptoms to watch out for include slow drains, or odd sounds in the pipes.
Such symptoms suggest the accumulation in the sewage line.
Clearing out drains is a way of preserving the cascading plumbing system.
5. Test the Valve Periodically
Even though the sewer backflow condition cannot be completely simulated by homeowners, periodic visual inspection can be used to detect the possible problems in time.
When the valve seems to be damaged or worn, it can be necessary to make a professional service.
6. Avoid Pouring Grease or Waste Down Drains
The most frequent causes of sewage blockage are kitchen grease, oils, wipers and hygiene products.
These substances may be deposited within the backflow valve sewer mechanism and cannot work.
Open drain strainers and place grease in containers rather than sinks.
7. Schedule Professional Inspection
It is advisable to have the valve checked by a skilled plumber after every one year despite the regular homeowner maintenance.
Professional checks make sure that the valve, sewer line, and other aspects of the residential plumbing system are in proper condition.
