Plumbing Smoke Testing

Plumbing smoke testing investigates drainage and vent-system leaks and odor pathways by introducing smoke into the system and observing where it escapes. Top Rate Plumbing explains preparation, interpretation, and limitations, and clarifies it is not combustion testing or a substitute for gas-leak emergency response.
