Frequently Asked Questions
Preparing your home for Ottawa's unpredictable weather is essential. Our comprehensive FAQ section is designed to answer your most pressing questions about backwater valve installations, municipal requirements, and how to protect your basement from costly water damage.
A backwater valve is a protective device installed on your sewer lateral line. It allows wastewater to exit your home but automatically closes if municipal sewer lines back up, preventing raw sewage from flooding your basement during heavy rains or rapid spring thaws.
Yes, the City of Ottawa offers financial assistance through the Residential Protective Plumbing Program. Eligible homeowners can receive rebates to help offset the cost of installing a backwater valve and sump pump, significantly reducing your out-of-pocket expenses.
While we recommend a professional plumbing inspection to assess your specific risk, backwater valves are highly recommended for homes in low-lying areas, older Ottawa neighbourhoods like The Glebe, or any property with a history of basement flooding.
Most standard installations are completed within a single day. Our licensed Red Seal plumbers will excavate a small area in your basement floor, install the valve, secure the concrete, and clean the workspace thoroughly before departing.
To ensure reliable operation, you should inspect the valve at least once a year. This involves removing the access cover, clearing out any accumulated debris or grease, and checking that the gate moves freely to block reverse flow.
