New plumbing systems and parts of existing systems which have been altered, extended, or repaired shall be inspected and tested by the proper administrative authority to ensure compliance with all the requirements of this code and the installation and construction of the system in accordance with the approved plan and the permit, except that testing may be waived for work which does not include addition to, replacement, alteration, or relocation of any water supply, drainage, or vent piping.
All the piping shall be tested and after the plumbing fixtures have been set, and before the system is put into use, the system shall be given a final inspection and test by the proper administrative authority.
The equipment, material, power, and labor necessary for the inspection must be furnished by the plumbing contractor.
It shall be the duty of the plumbing contractor to notify the proper administrative authority and the owner or the owner's authorized agent orally, by telephone, or in writing, not less than eight working hours between the hours of 8:00 a.m. and 4:00 p.m. before the work is to be inspected or tested. It shall be the duty of the plumbing contractor to make sure that the work will stand the test prescribed before giving the above notification. If the proper administrative authority finds that the work will not stand the test, the plumbing contractor shall be required to renotify as above. If the proper administrative authority does not appear for an inspection within 24 hours of the time set, excluding Saturdays, Sundays, and holidays, the inspection or test shall be deemed to have been made, and the plumbing contractor is required to file an affidavit with the proper administrative authority that the work was installed in accordance with the code, the approved plans and permit, and that it was free from defects and that the required tests had been made and the system found free from leaks; also whether the owner or the owner's authorized agent was present when such inspection or test was made.
No building drainage or plumbing system or part thereof shall be covered until it has been inspected, tested, and approved as herein prescribed.
If any building drainage or plumbing system or part thereof is covered before being regularly inspected, tested, and approved, as herein prescribed, it shall be uncovered upon the direction of the proper administrative authority.
The building sewer shall be inspected by the proper administrative authority to ensure compliance with the provisions of the code.
Upon the satisfactory completion and final inspection of the plumbing system, a certificate of approval shall be issued by the proper administrative authority.
Prior to the installation by any person, corporation, or public agency, of a system of plumbing that serves the public or that serves any considerable number of persons, or any plumbing system that shall affect the public health in any manner, complete plans and specifications, together with any additional information that the commissioner of health may require, shall be submitted in duplicate and approved by the commissioner. The appraisal of the commissioner shall reflect the degree to which these plans and specifications affect the public health and conform to the provisions of the Minnesota Plumbing Code. No constructions shall proceed except in accordance with approved plans. Any material alteration or extension of the existing system shall be subject to these same requirements. This rule shall not apply to cities of the first class, except those plumbing installations in hospitals or in buildings in these cities owned by the federal or the state government.
There shall be no physical connection between water supply systems that are safe for domestic use and those that are unsafe for domestic use. There shall be no apparatus through which unsafe water may be discharged or drawn into a safe water supply system.
