Codes & SafetyQuestion 104 of 120
Underground drainage piping is installed, and the crew backfills and compacts the trench before the groundwork inspection is called for. What does the code require?
a.The work is accepted if the plumber photographed the piping and the joints before backfilling
b.The inspector may simply carry the groundwork over and approve it at the rough-in inspection
c.A reinspection fee is paid and the buried piping is accepted as installed
d.The concealed work must be uncovered and exposed for inspection, and the cost of uncovering and restoring it is borne by the permit holder
Explanation
Inspections follow a set sequence, typically groundwork or underground, then rough-in or top-out, then final, and no portion of the work may be covered or concealed until it has been inspected and approved. When work is covered early, the code allows the inspector to require it to be uncovered at the permit holder's expense. Photographs are not a substitute for the inspector's own examination and pressure test. Paying a reinspection fee covers the inspector's return trip; it does not buy approval of work no one has seen.
