Smoke testing is the most efficient and cost effective way to locate and identify infiltration and exfiltration problems in sewer systems. It is used to find both leaks and illegal connections to sewer lines. Smoke testing is becoming a requirement nationwide for locating the problems that are threatening our supply of clean water and costing millions of dollars in additional waste water treatment. Smoke testing helps identify plumbing leaks in buildings.
Sewer gases can cause health problems for building occupants.
Smoke testing involves forcing smoke-filled air through a sewer line. Only enough force to overcome atmospheric pressure is required. As long as openings exist for the smoke to follow, smoke tests are effective, regardless of surface type, soil type and depth of lines. CFM can be varied by throttle control.
