Sec. 107.1. Testing Of Plumbing Work.

(a) Inspections.

(1) Scope. All new plumbing work and such portions of existing systems as may be affected by new work, or any changes, shall be inspected by the building official or a duly authorized representative as required in this code.

(2) Responsibility. It shall be the duty of the holder of a permit to make sure that the work will stand the test prescribed before notifying the building official that said work is ready for inspection.

(3) Test. Tests shall be conducted in the presence of the building official or a duly authorized representative.

(4) Retesting. If the building official finds that the work will not pass the required test, necessary corrections shall be made and the work shall then be resubmitted for test or inspection.

(b) Testing.

(1) Responsibility. The equipment, material, and labor necessary for inspection or tests shall be furnished by the person to whom the permit is issued or by whom inspection is requested.

(2) Media. The piping of the plumbing, drainage, and venting systems shall be tested with water or air. The building official may require the removal of any cleanouts, etc., to ascertain if the pressure has reached all parts of the system. After the plumbing fixtures have been set and their traps filled with water, they shall be submitted to a final test.

(3) Water Test. The water test shall be applied to the drainage and vent system either in its entirety or in sections. If applied to the entire system, all openings in the piping system shall be tightly closed, except the highest opening, and the system filled with water to the point of overflow. If the system is tested in sections, each opening shall be tightly plugged except the highest opening of the section under test, and each section shall be filled with water, but no section shall be tested with less than a ten-foot (3 m) head of water. In testing successive sections, at least the upper ten (10) feet (3 m) of the next preceding section shall be tested, so that no joint or pipe in the building (except the uppermost ten (10) feet (3 m) of the system) shall have been submitted to a test of less than a ten-foot (3 m) head of water. The water shall be kept in the system, or in the portion under test, for at least fifteen (15) minutes before inspection starts. The system shall then be tight at all points.

(4) Air Test. The air test shall be made by attaching an air compressor testing apparatus to any suitable opening, and, after closing all other inlets and outlets to the system, forcing air into the system until there is a uniform gauge pressure of five (5) pounds per square inch (34.5 kPa) or sufficient to balance a column of mercury ten (10) inches (254 mm) in height. The pressure shall be held without introduction of additional air for a period of at least fifteen (15) minutes.

(5) Building Sewer Test. The building sewer shall be inspected and approved by the building official before being concealed. Neither the building official nor the city shall be liable for expense entailed in the removal or replacement of material required to permit inspection.

(6) Water Piping. Upon completion of a section or of the entire hot and cold water supply system, it shall be tested and proved tight under a water pressure test not less than the working pressure under which it is to be used. The water used for test shall be obtained from a potable source of supply. A fifty (50) pounds per square inch (344.5 kPa) air pressure may be substituted for the water test. In either method of test, the piping shall withstand the test without leaking for a period of not less than fifteen (15) minutes.

(7) Defective Systems. An air test shall be used in testing the sanitary condition of the drainage or plumbing system of any building premises when there is reason to believe that it has become defective.

(8) Moved Structures. All parts of the plumbing systems of any building or structure that is moved into or within the jurisdictional limits of the city, shall be completely tested as prescribed elsewhere in this section for new work, except that walls or floors need not be removed for such test when other equivalent means of inspection acceptable to the building official are provided.

(9) Test Waived. No test or inspection shall be required where a plumbing system, or part thereof, is set up for exhibition purposes and has no connection with a water or drainage system.

(10) Exceptions. In cases where it would be impractical to provide the aforementioned water or air tests, or for minor installations and repairs, the building official, at the building official's discretion, may make such inspection as the building official deems advisable in order to assure the building official that the work has been performed in accordance with the intent of this code.

(11) Tests For Shower Receptors. Shower receptors shall be tested for water tightness by filling with water to the level of the rough threshold. The test plug shall be so placed that both upper and under sides of the subpan shall be subjected to the test at the point where it is clamped to the drain.

(12) Protectively coated pipe inspection and repair shall conform to section 318.1 of IAMPMO installation standard IS 13, listed in table A.

Section 108.2 Notice Of Violation. Amended to read:
