Missouri Backflow Prevention & Cross-Connection Control Contractor

No, Missouri does not issue a centralized statewide backflow specialist license. Instead, contractor licensing, competency examinations, surety bonds, and permit authorizations are delegated to municipal building inspection departments (such as Kansas City City Planning & Development, City of St. Louis Building Division, City of Springfield, City of Columbia). Contractors must register with each city or county building department where projects are located and comply with local building codes before pulling permits.

Backflow Prevention & Cross-Connection Control Contractor installations in Missouri must strictly adhere to the Uniform Plumbing Code (UPC) / International Plumbing Code (IPC) & ASSE 5000 as adopted by local municipal jurisdictions. In addition, all completed work and materials must satisfy ASSE 1013 reduced pressure backflow testing and NSF/ANSI 61 lead-free potable water certifications to pass municipal building inspection.

Backflow Specialists in Missouri typically must maintain a minimum of $1,000,000 Each Occurrence / $2,000,000 General Aggregate in commercial general liability insurance.

Because Missouri delegates backflow specialist licensing to municipal jurisdictions rather than issuing a centralized statewide license, statewide exam reciprocity agreements do not exist for this trade. Licensure and permit authorization are handled locally by municipal building departments (such as Kansas City City Planning & Development, City of St. Louis Building Division, City of Springfield, City of Columbia) rather than through statewide reciprocity. Many cities evaluate ICC certification or previous jurisdiction credentials, but registration and bonding must be satisfied individually with each municipal building authority.
