Smoke Testing is a method of finding leaks in plumbing and sanitary sewer systems. It is primarily used to find places where ground water and storm runoff can enter the sanitary sewer system.
Non-toxic artificially created smoke is forced into the pipe or container. Plumes of smoke form where there are defects. It is particularly useful where completely sealing the system is not practical such as ventilated sanitary sewer systems.
Smoke testing is not typically helpful in assigning a condition score to an asset.
