All corners after duct is pressurized not checked
During a pressure/leakage test, find corner leaks methodically instead of guessing. Mark each confirmed leak while the system is pressurized, then repair after the test is safely stopped/depressurized as directed.
Watch out Do not chase leaks randomly, repair while the test is running without direction, or call every air movement a confirmed leak. Check Work joint-by-joint and corner-by-corner, not randomly. Listen/feel for leaks and use smoke/soap/approved leak method only if allowed on the job. Mark each confirmed leak with tape or marker and note room/grid/system. Separate TDC corner, gasket, flange gap, and duct seam leaks. Depressurize/hold the system before repair if required by the test procedure.

Do you want me to mark confirmed leaks first, then depressurize and repair in order?
