Do I need to service my backwater valve yearly?

Yes, backwater valves should be inspected and serviced annually to ensure they'll function properly when you need them most. A malfunctioning backwater valve during heavy rainfall or sewer system overload could result in thousands of dollars in basement flooding damage.

Annual maintenance involves several key steps. A licensed plumber will remove the valve cover, inspect the flapper mechanism for debris or damage, clean out any accumulated sediment, and test that the flapper moves freely and seals completely. They'll also check that the valve housing isn't cracked and verify proper installation depth according to Ontario Building Code requirements.

In Ottawa's climate, backwater valves face unique challenges that make regular service even more important. Our freeze-thaw cycles can cause ground movement that affects valve alignment, while spring snowmelt and summer storms put extra stress on the city's sewer system. Many Ottawa homeowners have learned the hard way that a $200 annual service call is much cheaper than dealing with sewer backup damage.

Between professional services, homeowners should perform basic checks every few months, especially before storm season. Remove the cover (when safe to do so) and visually inspect for obvious debris or damage. However, never attempt to disassemble or repair the valve yourself - improper installation can void your insurance coverage and create liability issues.

Keep detailed service records as many insurance companies require proof of regular maintenance to honor sewer backup claims. Schedule your annual service in early spring before Ottawa's heavy rain season begins.
