Section 5: That Chapter 3, Section 309, is amended to i! read as follows: "Sec. 309 - Method of Testing All the piping of a sanitary plumbing and/or drain- age system shall be tested with water or air in the following manner: (1) WATER TEST: The water test shall be applied to the plumbing and/or drainage system in its entirety or in sections. If applied to the entire system, all openings in the piping shall be tightly closed except the highest opening above the roof or other highest point and the system filled with water to the point of overflow. All dead ends shall be relieved of air during the process of filling, whether in sections or entirety. If the system is tested in sections, each opening shall be tightly closed except the highest opening under test, and each section shall be filled with water, but no section shall be tested with less than ten (10) foot head of water or a five (5) pound pressure of air. In testing successive sec- tions, the upper ten (10) feet of the next preceding section shall be retested, so that the entire system will be submitted to a test of at least ten (10) foot head of water or a five (5) pound pressure of air. Under any test, the water or air pressure shall remain constant for not less than fifteen (15) minutes without any further addition of water or air, or showing of leaks. (2) AIR TEST: The air test shall be made by attaching the air compressor or test apparatus to any suitable opening, and closing all other inlets and outlets to the system, then forcing air into the system until there is a uniform pressure sufficient to balance a column of mercury ten (10) inches in height, or five (5) pounds per square inch on the entire system. This pressure shall be maintained for fifteen (15) minutes without showing a loss. Vater or other liquids shall not be used to test gas piping for tightness. See Sec. 1505, for methods of testing gas piping." Section 6: That Chapter 6, Section 606, is amended to read as follows: "Section 606 - Prohibited Fittings and Practices No double hub fitting, single or double Tee branch, single or double Tap Tee branch, side inlet quarter bend, running thread, band or saddle shall be used as a drainage fitting. Drive ferrel lead stubs or bends shall not be per- mitted. Factory poured lead inserts in drainage fittings shall not be permitted. No drainage or vent piping shall be drilled and tapped for the purpose of making connections thereto.
