When a permit has been issued for plumbing work, the construction of such plumbing shall be subject to the inspection of the Plumbing Inspector at all times, and the Building Official may revoke such permit at any time when the work is not being done in accordance with the ordinances of the City or the rules and regulations of the State Board of Health. It is unlawful for any person to proceed further with such work without the written consent of the Building Official. When the water service pipe has been completed from the water main to the stop and waste cock in the basement and before such work has been covered or in any way concealed from view or any fixture set, the work shall be inspected as follows:
1. It shall be the duty of the master plumber or his representative to notify the building official either by telephone or in writing not less than eight working hours between the hours of eight a.m. and four p.m. before the work is to be inspected or tested, giving the permit number, location of work and the time when such work will be ready for inspection.
2. It shall be the duty of the plumber to make sure that the work will stand the test prescribed before giving the above notification.
3. If, after inspection, the building official finds that the work will not stand the test, the plumber shall be required to re-notify as specified in subsection 1 of this section and pay a sum sufficient to cover all expenses for each such additional inspection.
4. If the building official or his authorized representative, after having been notified in writing, fails to appear within twenty-four hours, exclusive of weekends and holidays, after such notification, the inspection or test is deemed to have been made, and the plumber is required to file an affidavit with the building official stating that the work was installed in accordance with this chapter and the permit, that it was free from defects, that the required tests had been made, and that the system was found free from leaks.
5. If any water service pipe is tested and found to fail to hold a water or air pressure of one hundred fifty pounds to the square inch, such service pipe shall be condemned and taken out of service.
