The permittee shall test the completed and backfilled sanitary sewer service connection between the plumbing stack in the serviced building, and the downstream end of the test tee by plugging the tee with an appropriate plumbers test plug and filling the connection with clean water to a point at least three feet six inches above the invert of the test tee. The test shall be conducted in the presence of the Commissioner of Buildings or his duly appointed deputy. The test shall be of thirty-minute duration. The test shall be observed by the Commissioner of Buildings or his deputy. A sounding of the water surface in the test riser shall be made after the first fifteen minutes of the test period has elapsed. A second sounding shall be taken at the end of the thirty-minute test period. The installation shall be considered satisfactory with respect to watertightness, if no perceptible difference in the water surface level is observed. The installation shall be considered unsatisfactory if a perceptible change in water surface level is observed. All soundings shall be taken by the Commissioner of Buildings or his deputy and recorded. If the test indicates leakage, such leakage shall be eliminated by the permittee and the test again conducted as described above.
