Smoke Emitter, 90 Second, Regin Std Smoke
Caution: Only introduce sewer smoke bombs into a plumbing system through a smoke blower. If smoke is put into a drain-waste-vent system in this manner, temperature is not an issue.
Under no circumstances should these industrial smoke bombs be placed inside of a pipe. (They will burn the pipe, may ignite any methane present in the line.)
