Backflow and cross connection control carries specific device, installation, and testing requirements, and a plumbing subcontractor that does not read them underprices the scope.
What backflow requirements set
Backflow prevention protects the potable water supply from cross connections, and the plumbing code and the project specifications set the assembly type, the location, and the testing and certification by a certified tester. The Division 22 specifications set the devices the sub must furnish, install, and test.
Why backflow scope is easy to miss
The assembly type, the count, and the testing and certification requirements sit in the Division 22 specifications, not the title. A sub that overlooks a required assembly or its certification underprices the device and the testing.
How an AI bid agent flags backflow requirements
An AI bid agent reads each plumbing package, flags the backflow and cross connection requirements, and surfaces the assemblies, the locations, and the testing that drive the work. The plumbing sub prices the actual scope.
You can see how the agent reads a plumbing package in our AI bid agent demo for MEP subcontractors. It flags the backflow assemblies and testing so the scope is priced.
