Notice to all Plumbing Contractors and Plumbers

NOTICE TO ALL PLUMBING CONTRACTORS, AND PLUMBERS

The cross connection control program requires that Licensed Plumbers complete the installation, and repairs or replacement of the backflow prevention devices.

Each device is tested following the installation to assure it is working properly. Each device is then required to be tested annually to assure it's continued operation. A certified backflow prevention device tester shall have successfully completed a cross connection control course in backflow prevention device testing at an accredited school or college. This requirement comes directly from the current CAN/CSA B64.10-94 standard.

All those successfully completing the above course will also require a license for testing of the devices by the City of Cambridge. To view the licensing fee please Click Here to view "Fee Schedule-Planning".

Permit for Devices

Each Backflow Prevention Device requires a Permit prior to installation. To view the permit fee please Click Here to view "Fee Schedule-Building".


This page provides general information and should be read in conjunction with the current Cross Connection Control By-Law.
