What is Smoke
Testing?
Smoke
testing is the process of forcing smoke filled air into the sewer
system. The smoke under pressure will fill the line and any
connections. Whether in a municipal mainline sewer, residential or
industrial system, breaks or illegal taps in the sewer line will
allow the smoke to escape and surface through the ground or pipe work
quickly revealing the source of the problem.
Why should
you smoke test?
-
The smoke is non-toxic and only
enough force to overcome atmospheric pressure is required to
adequately fill the system. As long as openings exist for the
smoke to flow, smoke tests are effective, regardless of surface
characteristics, soil make-up and depth of sewer lines.
Before Smoke
testing can take place local police and fire agencies must be notified, as
well as any potential residential or industrial connections to the
line being tested.
