Backflow Prevention in Markham
The Importance of Backflow Prevention in Markham, Ontario

Safeguarding Ontario’s Water Systems
Backflow prevention is critical for ensuring the safety of Markham’s water supply. Backflow can occur when water flows in reverse, potentially allowing contaminants like chemicals and bacteria into the clean water system. Ontario regulations require properties with potential cross-connections to install certified backflow prevention devices. Regular testing and maintenance are essential for keeping the system operational and compliant with local laws, ensuring the safety of the community’s drinking water.
Certification and Compliance
In Ontario, backflow prevention device installation, inspection, and maintenance must be performed by certified professionals. The Ontario Water Works Association (OWWA) offers comprehensive certification and recertification programs to ensure that professionals remain updated on best practices and regulations. Additionally, property owners must ensure their systems are regularly inspected and compliant with local bylaws.
