Smoke testing is an accurate and effective way of locating and identifying the presences of defects, leaks or improper connections in underground or in-wall pipes, sewer and stormwater systems. Drain Stormers uses smoke testing, a non-toxic, artificially created smoke that mixed with air will penetrate throughout waste and drain pipes under slight pressure to detect cracks, leaks or breaks in closed pipe systems. Any sign of smoke escaping can indicate possible gas or water leakage. Smoke tests are effective, regardless of surface characteristics, soil make-up and depth of sewer lines.
