The project inspection plan requires a witnessed water-riser pressure test before joints are insulated. The riser is insulated first and a leak later appears. What quality step was missed?
Correct Answer
A) The pressure test required before joints were covered
The required test and acceptance hold point was skipped before the joints became concealed. Expose what is necessary, repair the leak and complete the required testing before restoring insulation. Greater insulation thickness cannot repair a leaking joint.
Why This Is the Correct Answer
The required test and acceptance hold point was skipped before the joints became concealed. Expose what is necessary, repair the leak and complete the required testing before restoring insulation. Greater insulation thickness cannot repair a leaking joint.
