Florida Commercial Septic Installer Exam Review 2026 |
Verified Q&A | Graded A+
1. What standards must the circuits used to feed residential lighting conform to?
General construction and safety guidelines, but not electrical codes
Standards established by only the NEC (national electric code)
Only manufacturer-specific guidelines
Standards established by the NEC (national electric code), as well as
local and state ordinances.
2. What device is used to prevent backflow into a septic tank?
Check valve
Septic tank lid
Grease trap
Dosing pump
3. Describe the significance of having a field line length of one thousand linear
feet or more in a septic system.
A field line length of one thousand linear feet is only necessary in
residential systems.
A field line length of one thousand linear feet or more is necessary
to ensure adequate sewage dispersion and prevent system
overload.
A field line length of one thousand linear feet is required for aesthetic
purposes.
A field line length of one thousand linear feet is irrelevant to system
performance.
,4. If a dosing tank's alarm system fails, what potential issue could arise for the
septic system?
Improper filtration
Increased energy consumption
Sewage overflow
Reduced tank capacity
5. What should you do to prevent damage in concrete due to freeze-thaw
cycles?
increase the permeability
entrap air
increase the w/c
entrain air
6. What is the primary focus of the regulations regarding electrical components
in septic systems?
Safety and compliance with electrical codes
Cost-effectiveness of installation
Aesthetic design of electrical components
Environmental impact of electrical systems
7. Describe the relationship between the tank's operating liquid capacity and
the absorption lines in a septic system.
The tank's capacity must be three times the volume of the absorption
lines.
The tank's capacity should be unrelated to the absorption lines.
, The tank's operating liquid capacity must match or exceed the
interior volume of the absorption lines to ensure effective dosing.
The tank's capacity can be less than the absorption lines as long as it is
regularly maintained.
8. Describe why it is important to prime siphons with water during installation.
Priming siphons helps to clean them before use.
Priming siphons with water ensures they function properly by
creating the necessary pressure for flow.
Priming siphons is only necessary for large systems.
Priming siphons prevents them from freezing in cold weather.
9. Why is it important for poured-in-place septic tanks to have a minimum
thickness of four inches?
To increase the tank's capacity for sewage.
To reduce the cost of materials used in construction.
To allow for easier installation of the tank.
To ensure structural integrity and durability of the septic tank.
10. In a scenario where a septic system is installed on a slope, what would be
the consequence of not using a check valve in the discharge pipe?
The grease trap would become clogged.
The system would operate more efficiently.
Sewage could flow back into the septic tank.
There would be no impact on the system.
, 11. What is the primary purpose of grease traps in septic systems?
To filter solid waste from liquids.
To store excess sewage temporarily.
To enhance the decomposition of organic matter.
To separate grease and oils from wastewater.
12. If a restaurant experiences an increase in customer volume, how should this
affect the sizing of their grease trap?
The grease trap should be ignored as it does not affect system
performance.
The grease trap size should remain the same regardless of customer
volume.
The grease trap should be replaced with a smaller model to save
costs.
The grease trap should be resized to accommodate the increased
flow rate of wastewater.
13. Describe the importance of adhering to electrical standards in septic system
installations.
Adhering to electrical standards ensures safety, prevents hazards,
and maintains system integrity.
Adhering to electrical standards is only necessary for large
installations.
Adhering to electrical standards only affects the appearance of the
system.
Adhering to electrical standards is optional and based on personal
preference.
