SCOPE: This review is limited to the design of this particular project only insofar as the provisions of the
Minnesota Plumbing Code, as amended, apply, and does not cover the water supply or sewerage system to which
this plumbing system is connected. The review is based upon the supposition that the data on which the design is
based are correct, and that necessary legal authority has been obtained to construct the project. 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, specifications, and this Report on
Plans must be retained at the project location for future reference.
INSPECTIONS: All plumbing installations must be tested and inspected in accordance with the requirements of
the Minnesota Plumbing Code. As specified in Minnesota Rules, part 4715.2830, no plumbing work may be
covered prior to completing the required tests and inspections. Provisions must be made for applying an air test at
the time of the roughing -in inspection as outlined in Minnesota Rules, part 4715.2820, subpart 2, of the code. A
manometer test, as specified in Minnesota Rules, part 4715.2820, subpart 3, is required at the time of the finished
plumbing inspection. It is the responsibility of the contractor /installer to notify the Minnesota Department of Labor
and Industry when an installation for a state contract job, Minnesota Department of Health licensed healthcare
facility, or project in an area where there is no local administrative authority is ready for an inspection and test. To
