If an irrigation bid lacks a backflow device, what should the technician do?

• A. None of the above; Install the backflow device, Call the city inspector, Call the irrigator to re-bid the proposal and select the right backflow for the degree of hazard.
• B. Install a backflow device only if required by code
• C. Submit a change order to re-bid the project
• D. Ignore the issue and continue

Answer: (A)

Backflow prevention is mandatory on irrigation connections to protect the drinking water supply. If a bid omits a backflow device, the proper course is to install the backflow preventer, involve the city inspector for approval or inspection, and have the project re-bid to reflect the added scope, choosing the correct backflow type based on the degree of hazard. This ensures compliance with code, proper permits, and a fair adjustment to the contract reflecting the change in work. Installing only if required by code isn’t enough because many jurisdictions require backflow protection for irrigation connections regardless of perceived hazard, and ignoring the issue or merely submitting a change order without coordinating with the inspector and re-bid would leave the project noncompliant.
