(a) The piping of drainage and vent systems shall be tested with water or air. After the plumbing fixtures have been set and the traps filled with water, the entire drainage system shall be submitted to a final inspection. The Building Inspector may require the removal of clean-outs or plugs or the unsealing of traps to ascertain whether the test medium has reached all parts of the system. All tests for acceptance shall be witnessed by the Building Inspector.
(b) 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 shall be tightly closed, except the highest openings, 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, by section, except that the building storm sewer and its connected yard and area drain, shall be tested with less than a ten-foot head of water. In testing successive sections above the building drain, at least the upper ten feet of the next preceding section shall be retested so that no joint or pipe in the building, except the uppermost ten feet of the system, shall have been submitted to a test of less than a ten-foot head of water. The water shall remain in the system, or in the portion under test, for at least fifteen minutes before inspection starts. The system shall be watertight.
(c) The building storm sewer and yard and area drains, including all piping from the curb to within five feet of the building, shall be tested separately. All traps, pipe fittings and joints shall be exposed to view when the test is made. Water shall be introduced into the system at a test "T" designated by the Building Inspector and in such quantity as deemed necessary by him or her. To be approved, the flow of water through the system shall be unobstructed and there shall be no leakage from any pipe, joint, trap or fitting.
(d) All interior leaders or downspouts shall be tested, made leak-free and inspected in the same manner as the waste and vent system.
