Which technique should a CPI inspector use to evaluate proper pool light niche sealing?
Answer: Visually inspect for rust stains, discoloration, or water trails around the niche face plate indicating water intrusion into the conduit
Rust stains and water trails around the light niche are visual indicators of conduit water intrusion, which creates an electric shock hazard in or around the pool.
A client asks an inspector whether the pool water is safe to swim in. What is the appropriate inspector response?
Answer: Explain that water chemistry testing is outside the scope of a CPI inspection and recommend a water test by a pool service professional
CPI inspectors assess equipment and structures, not water chemistry; directing the client to a qualified pool service professional is the correct response within the inspector's defined scope.
During a pool inspection, the inspector observes that the pool's pressure-side automatic cleaner booster pump lacks an independent time clock and runs whenever the main pump runs. What is the concern?
Answer: Running the booster pump continuously with the main pump can exceed the designed operating hours and void warranties, and may violate local energy codes
Booster pump manufacturers and some energy codes require a separate timer so the booster only operates for the required daily cleaning cycle, not for the full filtration cycle.
An inspector is documenting a pool where the return jets have been repositioned by the owner and now point straight down toward the pool floor instead of angling toward the surface. What is the impact the inspector should note?
Answer: Downward-pointing returns reduce surface circulation and can create dead zones where algae and chemical stratification occur
Return jets should be angled to promote surface circulation; pointing them downward reduces skimming effectiveness and can lead to poor chemical distribution and algae growth.
A CPI inspector identifies a deficiency but is uncertain whether it violates the current local code or was acceptable under the code in effect when the pool was built. How should the inspector handle this in the report?
Answer: Document the observed condition as a deficiency or concern and recommend the client verify code compliance with the local building authority
CPI inspectors are not code officials and should document observable conditions while directing code-specific determinations to the authority having jurisdiction.
When testing a pool heater during an inspection, the inspector notes the heater ignites but the water temperature at the return does not rise noticeably after 10 minutes of operation. What should the inspector check next?
Answer: Verify the bypass valve or mixing valve setting is not diverting flow around the heat exchanger
A bypass or mixing valve set to divert flow around the heat exchanger is a common reason a heater fires but produces no meaningful water temperature rise.
Which of the following best describes the 'drainage and deck slope' check performed during a pool inspection?
Answer: Verify the deck slopes away from the pool coping at a minimum grade to prevent water from draining back into the pool or pooling near the structure
Proper deck slope (typically 1/8 to 1/4 inch per foot) directs runoff away from the pool, preventing contamination and structural damage from water infiltration near the pool shell.
