1. Which factor is most important when determining the structural
requirements for a swimming pool or spa installation in Colorado?
A. The color of the interior finish
B. The brand of circulation pump
C. Site conditions, soil characteristics, structural design, and applicable
building requirements
D. The preferred pool-water temperature
The structural design of a pool or spa must account for site-specific
conditions such as soil, groundwater, loads, drainage, and the applicable
building requirements.
2. Before excavation begins for an in-ground swimming pool, what
should the contractor do first regarding underground utilities?
A. Begin excavation slowly and watch for warning tape
B. Have underground utilities properly located and marked through the
required utility-locating process
,C. Assume utilities are located only along property boundaries
D. Obtain the pool manufacturer's approval
Underground utilities must be located before excavation so that
electrical, gas, water, communication, and other buried facilities are not
damaged.
3. Why is proper pool-site drainage particularly important in
Colorado?
A. Drainage eliminates the need for pool waterproofing
B. Drainage prevents all evaporation
C. It helps control surface water and groundwater that can damage the
pool structure, surrounding property, or adjacent improvements
D. Drainage makes chemical treatment unnecessary
Proper drainage reduces hydrostatic pressure, erosion, settlement, and
water intrusion that can adversely affect the pool and surrounding
structures.
4. What is the primary purpose of reinforcing steel in a gunite or
shotcrete pool shell?
A. To improve water color
B. To reduce chlorine demand
C. To provide tensile reinforcement and help the concrete shell resist
structural stresses and cracking
D. To increase circulation velocity
,Concrete performs well in compression but poorly in tension, so
reinforcing steel is used to resist tensile stresses and improve structural
performance.
5. When placing reinforcing steel in a pool shell, why must adequate
concrete cover be maintained?
A. To increase pool capacity
B. To make plaster application unnecessary
C. To protect reinforcement from corrosion and provide proper
structural performance
D. To reduce the size of the excavation
Adequate concrete cover helps protect reinforcing steel from moisture
and corrosive conditions while maintaining the intended structural
capacity of the shell.
6. What is the principal purpose of a pool's circulation system?
A. To increase water evaporation
B. To eliminate the need for filtration
C. To move water through filtration and treatment equipment and
distribute treated water throughout the pool
D. To prevent all water-temperature changes
Continuous or appropriately controlled circulation moves water through
the filter and treatment system and returns treated water to the pool.
7. What is the primary function of a swimming-pool filter?
, A. To heat the water
B. To add chlorine automatically
C. To remove suspended particulate matter from the circulating water
D. To increase water hardness
A filter removes suspended particles and debris from pool water,
improving water clarity and supporting effective sanitation.
8. Which type of filter commonly uses a porous cartridge that can be
removed for cleaning or replacement?
A. Sand filter
B. Diatomaceous-earth filter
C. Cartridge filter
D. Gravity settling basin
A cartridge filter contains a replaceable or cleanable filter element that
traps suspended contaminants as water passes through it.
9. What is the purpose of a pool pump strainer basket?
A. To regulate chlorine concentration
B. To catch larger debris before it reaches the pump impeller
C. To increase water temperature
D. To measure alkalinity
The pump strainer basket captures leaves, hair, and other larger debris,
protecting the impeller and reducing the risk of blockage.
10. What condition can occur if a pool pump operates with
insufficient water reaching its suction side?
