Backflow Testing & Prevention Services -Saskatoon

Protect Your Water Supply. Stay Code Compliant.

In commercial and industrial settings, backflow prevention is essential to protecting Saskatoon’s municipal water supply from contamination. Backflow occurs when water flows in the wrong direction—allowing potentially harmful chemicals, waste, or other contaminants to enter clean water lines.


At MNS Mechanical Limited, we provide certified backflow testing, installation, and repair services to help your building stay safe and compliant with city regulations.

Why Backflow Prevention Matters

Backflow can pose serious health risks to building occupants and the broader community.

City of Saskatoon regulations—and many insurance policies—require annual backflow testing for commercial and multi-residential buildings with pressurized systems.

Common sources of backflow include:

Irrigation systems and sprinkler lines

Fire suppression systems

Boilers and hydronic heating loops

Commercial dishwashers and food prep areas

Car washes, workshops, and industrial chemical lines
