Backflow Prevention

City Of Toronto Backflow Prevention Program

Ever since the contaminated water incident at Walkerton most municipalities have adopted Bylaws to ensure that the municipal water supply does not cross connect with any potential hazards that reside within the buildings they serve.

This is called Premise Isolation.

To comply with the Bylaw you are required to install a backflow preventor immediately after the water meter. It is important to select the correct device for your building and understand the impact this device will have on your current system.

When selecting a device it is important to consider pressure loss, thermal expansion, water hammer, drainage, installation height for servicing, strainers and permit requirements.

Once installed these devices must be tested annually and all documentation submitted to the City of Toronto for their records.

When selecting a Contractor to work for you it is important to ensure they are on the approved list to perform this work as well as their familiarity with this type of work. We have been educating our customers and performing surveys for years and would like to offer our services to your company.

We will assist your company to comply with the Bylaw and ensure that you provide your employees with safe drinking water. We will further ensure your facilities do not run the risk of contaminating the City’s supply lines. If you have any questions please do not hesitate to call me.
