Service Area

We are experienced working with various municipalities across Ontario and ensure our clients meet the unique requirements of each backflow prevention program. We take responsibility to remain current with any changes to municipal by-laws.

Types of Properties

Backflow protection is required in industrial, commercial, institutional and multi-residential properties, where there is a greater potential for contamination to the public’s water supply. These properties must have a backflow prevention device installed after the water meter on the main domestic line and any sprinkler lines coming in from the public water supply line at minimum. The potential hazard for cross-contamination varies for each type of property resulting in varied degrees of hazard to the purveyor’s system. EOS Mechanical Inc. has the experience and expertise to work in all capacities to ensure cross-contamination of our public water system does not occur.
