Permit and Qualifications Requirements
Saint Paul Regional Water Services (SPRWS) requires plumbing contractors to obtain a plumbing permit before installing or replacing a backflow preventer.
Only a person licensed by the Minnesota Department of Labor and Industry as a journeyman plumber may lawfully install, replace or rebuild backflow preventers; such person must also have a Certificate of Competency as a plumber/gasfitter issued by the City of Saint Paul Department of Safety and Inspections.
Annual Testing Requirements
Codes: Minnesota State Plumbing Code Section 4714.0603.5.23 as well as Saint Paul Legislative Code Section 94.18 require annual testing of reduced pressure zone (RPZ) assemblies and testable double check valve assemblies.
Tester qualifications: Only a person licensed by the Minnesota Department of Labor and Industry as a “backflow preventer tester” may perform backflow preventer tests.
Documentation requirement: To ensure the safety of public health and comply with code requirements, SPRWS requires annual submittal of complete documented test results on its Backflow Preventer Test Report. Failure to provide this annually required documentation is a code violation and may result in discontinuation of water service.
Filing fees: No permit is required for testing or rebuilding a backflow preventer, however a filing fee does apply. See Backflow Preventer Test Report for current fee details.
Payment: The plumber is not responsible for paying the testing fee beginning on January 1, 2018. The $35 testing fee will be applied to the customer's water bill.
