___________________.
a. By an architect
b. When the final plumbing is complete
c. Before work is begun
d. When footings for a new building are ready to be poured - Answer: c - All plumbing permits are
required to be issued prior to any plumbing work being started. Beginning any portion of plumbing work
before a permit is issued is a violation of the plumbing code. Some jurisdictions require that all permits
be posted conspicuously so that they can be seen from the road or street that a property fronts on. In
existing homes this is often done by posting the permit in a window where it can be seen easily by a
code officer approaching the property. New construction sites often have the permits posted in
weather-resistant coverings on poles or posts that are readily visible from vehicular routes.

a. The master plumber to whom the permit is issued
b. An authorized code enforcement officer
c. Both a master plumber and code officer
d. The property owner - Answer: b - All plumbing permits are to be signed by a licensed plumbing
inspector. The signature of an inspector is the only signature required on a permit.

service.

b. False - Answer: a - True - It is common for a code enforcement office to want a site plan and
specifications on file prior to any work being done on an existing sewer or water service. The site plan
should show the location of existing piping and the proposed location for new piping.
Your boss has asked you to create a schedule for maintenance on a large building. How often should
backflow preventers be inspected?
a. Monthly
b. Quarterly
c. Bi-Annually
d. Annually - Answer: d - Backflow assemblies and air gaps are required by code to be inspected once a
year. The devices should be tested. They must be working properly and not allowing contamination to
the water source of a water distribution system. They are also required to be inspected when they are
installed. If any repairs are done to the devices, a test and inspection of the repaired device must be
performed. Additional devices that require this same procedure include the following:
• Double check valve assemblies
• Reduced pressure detector fire protection backflow prevention assemblies
• Double check detector fire protection backflow preventers
• Spill-proof vacuum breakers
• Backflow preventers on any hose connections
• Reduced pressure principle backflow preventer assemblies
