Escaping smoke revealed improperly seated pads and faulty joints (i.e. leaks). After this test the instrument was cleaned to remove nicotine and other deposits left by the ...
In a modern time, vacuum testing is performed to check integrity of manholes and identify for leaks. [32] Another common testing method is smoke testing. In this method, sandbags are used to seal a sewer section, then smoke is pumped into a manhole. Any leaks can be observed by visible smoke at the areas of the leaks. [33]
Smoke testing refers to various classes of tests of systems, usually intended to determine whether they are ready for more robust testing. The expression probably was first used in plumbing in referring to tests for the detection of cracks, leaks or breaks in closed systems of pipes.
