(a) An air test shall be made by attaching an air compressor or testing apparatus to a suitable opening, and, after closing all other inlets to the system, forcing air into the system until there is a uniform gauge pressure of five pounds per square inch, sufficient to balance a column of mercury ten inches in height. This pressure shall be held, without the introduction of additional air, for a period of at least fifteen minutes.
(b) Other types of tests, such as smoke or peppermint, may be performed where appropriate or necessary to locate leaks or to test the proper drainage of fluid from the system. These tests shall be made in accordance with accepted practice for such tests. However, such tests shall not replace the air or water pressure tests for the drainage or vent system unless specifically approved by the Building Inspector.
