Backwater Valve
How Does It Work?
Designed with an open gate mechanism, a backflow valve in Montreal allows unrestricted airflow through branch lines, including the main sewer backflow line, while preventing reverse flow during sewer backups. This ensures that wastewater cannot enter your basement during heavy rain or municipal sewer surges. Proper installation and regular maintenance of the valve help protect your home from costly water damage and keep your plumbing system functioning efficiently.
