Smoke Testing

 A smoke test is a diagnostic method used in plumbing to locate leaks, breaks, or improper connections in a home’s drain, waste, and vent (DWV) system—problems that are often hidden behind walls, under slabs, or in ceilings 

 A smoke test safely fills your plumbing vents with visible smoke so we can see exactly where sewer gases or leaks are escaping—without opening walls or digging.
