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 and specifications should be retained at the project location for future reference. A set of the identified plans and specifications is being returned to Mid -City Mechanical Corporation. Enclosed is a copy of the report and transmittal letter to be forwarded to the project owner. 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 Health when an installation for a state contract job, licensed facility, or project in an area where there is no local administrative authority is ready for an inspection and test. To schedule inspections, contact the state plumbing standards representative for your region, or call the metro office inspection hotline at 1- 800 -926- 6216 (7:30 a.m. to 9 a.m.), or 651/215 -0836 (8 a.m. to 9 a.m.) on Monday, Wednesday or Friday.
