(a) Tests. All piping of a drainage or roughed in plumbing sanitary system shall be given two tests by the plumber in charge. The material and labor for the tests shall be furnished by the plumber and tests made in the presence of the Plumbing Inspector. The tests shall be made in the following order: first, the house drains; second, the soil and waste vents and all vertical piping on the whole system. The first and second tests may be combined but the second shall not be made until after the first. Soil, waste and vent and all work known as "rough" work inside conductor pipe stacks and between the house drain connections to points above the finished and beyond the finished face of walls and partitions, shall be tested when the whole stack is completed and topped out above the roof, with water. The water test shall be applied by closing the opening at the outlet end of the house drain and all openings in the piping with proper testing plugs to the highest opening above the roof, and completely filling the system with water. The water columns shall be left standing at least fifteen minutes. If the water level remains constant such time, the system shall be acceptably tested. The house drainage shall be acceptably tested when subjected to a ten foot water head for fifteen minute constant level. All alterations, repairs or extensions which include more than ten feet shall be inspected and tested.
(b) Defective Work. If tests show defects, the defective work or material shall be replaced within three days and the test again applied. In all cases the Inspector shall designate the point at which the pressure shall be relieved or drawn off.
