The responsibility for the design of structural features and the efficiency of equipment must be taken by the project designer. Approval is contingent upon satisfactory disposition of any requirements included in this report. Special care should be taken to insure that the material and installation of the plumbing system are in accordance with the provisions of the Minnesota Plumbing Code. A copy of the approved plans and specifications should be retained at the project location for future reference. A set of the identified plans and specifications is being returned to Bredahl Plumbing Inc.

The installation of reduced pressure zone backflow preventers is permitted only when periodic testing is done by a trained backflow preventer tester acceptable to the administrative authority. Testing intervals shall not exceed one year, and records must be kept. All devices must be tested after initial installation to assure that debris from the piping installation has not interfered with the functioning of the device. The devices shall be overhauled at least once every five years. The installation of new backflow preventers must be at least 12 inches, but not more than 6 feet above the finished floor or ground level. NOTE(S): 1.
