A plumbing contractor is asked to perform regulated work without
obtaining a required permit. What is the most appropriate response?
A. Proceed because the owner requested it
B. Explain that the required permit and applicable authorization must
be addressed before proceeding
C. Have an apprentice obtain the permit without supervision
D. Perform the work secretly and request inspection afterward
Answer: B
Rationale: Required permits are part of the construction-code
administration process. A contractor should not knowingly bypass
required permitting procedures simply because a customer requests it.
The appropriate approach is to determine the applicable permit
requirements and obtain the required authorization before regulated
work proceeds.
Which person is generally responsible for ensuring that plumbing work
is performed according to the applicable code and permit
requirements?
,A. The plumbing contractor and responsible plumbing professionals
B. The material manufacturer alone
C. The property appraiser
D. The utility billing department
Answer: A
Rationale: A plumbing contractor has significant responsibility for
performing contracted work in compliance with applicable laws, codes,
permits, and regulations. Other parties may have responsibilities as
well, but a contractor cannot transfer its regulatory responsibilities to a
manufacturer or unrelated agency.
What is the principal purpose of a plumbing inspection?
A. To determine the contractor's profit
B. To approve the contractor's advertising
C. To evaluate regulated work for compliance with applicable
requirements
D. To establish the property's selling price
Answer: C
Rationale: Inspection is an important part of code enforcement. The
authorized inspector evaluates covered work to determine whether it
complies with applicable construction-code and permit requirements.
If concealed plumbing work will make a required inspection impossible,
what should the contractor generally do?
,A. Conceal the work immediately
B. Photograph it and assume inspection is unnecessary
C. Ask the owner to waive the inspection
D. Coordinate the required inspection before the work is concealed
Answer: D
Rationale: Required inspections are ordinarily performed at stages
established by the applicable code and administrative procedures.
Concealing work before the required inspection can create significant
compliance problems and may require the work to be exposed again.
Which document generally establishes the authorized scope of
permitted plumbing work?
A. The plumbing permit and approved construction documents, where
applicable
B. The contractor's business card
C. The supplier's invoice
D. The employee handbook
Answer: A
Rationale: A permit and associated approved documents establish the
scope and conditions under which regulated work may be performed.
Contractors should compare field work against those documents and
applicable code requirements.
, A plumbing contractor discovers that an installation differs from the
approved plans. What should the contractor do first?
A. Ignore the difference
B. Determine whether the change requires approval, revised documents,
or another authorized procedure
C. Remove the entire plumbing system
D. Ask the material supplier to approve the change
Answer: B
Rationale: A field change may affect compliance and may require an
approved revision or other administrative action. The contractor should
evaluate the change under the applicable requirements rather than
assuming that any field modification is automatically acceptable.
Which condition is most likely to create a sanitary drainage problem?
A. Correctly sized and supported drainage piping
B. Properly installed cleanouts
C. Inadequate slope or improper drainage-system configuration
D. Properly protected potable water
Answer: C
Rationale: Drainage systems depend on proper configuration and
adequate slope for reliable gravity flow. Improperly designed or
installed drainage piping can contribute to sluggish flow, accumulation
of solids, blockages, and other drainage problems.
