CPI Inspection Techniques & Reporting 2 — Questions and Answers
Question 1: When inspecting a pool deck for trip hazards, what is the generally accepted maximum vertical displacement between adjacent sections?
- 1/4 inch (Correct answer)
- 1/2 inch
- 3/4 inch
- 1 inch
Correct answer: 1/4 inch
A vertical displacement greater than 1/4 inch between adjacent deck sections is typically flagged as a trip hazard during a CPI inspection.
Question 2: A CPI inspector notices the pool pump motor runs but produces very low water flow. Which inspection technique best identifies the root cause?
- Check the pressure gauge on the filter and inspect the strainer basket for blockage (Correct answer)
- Measure the voltage at the pump disconnect
- Inspect the pool light conduit for water intrusion
- Test the bonding wire continuity at the pump motor
Correct answer: Check the pressure gauge on the filter and inspect the strainer basket for blockage
Low flow with a running motor typically indicates a restriction; checking filter pressure and strainer basket blockage directly identifies the most common causes.
Question 3: During a spa inspection, the inspector observes the air blower intake is located inside the equipment enclosure. What is the primary concern?
- Carbon monoxide or exhaust gases could be drawn into the spa water (Correct answer)
- The blower will overheat without outside air supply
- The intake will restrict air volume below minimum flow
- The blower is not accessible for servicing
Correct answer: Carbon monoxide or exhaust gases could be drawn into the spa water
A blower intake inside an enclosed equipment space can draw combustion gases from nearby heaters into the spa, creating a CO poisoning hazard.
Question 4: Which method is most appropriate for an inspector to assess proper anti-entrapment drain cover installation?
- Visually verify the cover is secured, undamaged, and matches the listed flow rate for the pump (Correct answer)
- Lift the cover and measure the sump depth with a tape measure
- Time how long it takes for a float to be pulled toward the drain
- Conduct a vacuum test with a gauge attached to the drain line
Correct answer: Visually verify the cover is secured, undamaged, and matches the listed flow rate for the pump
CPI inspectors visually confirm the cover is properly secured, free of cracks, and rated for the pump's maximum flow to ensure anti-entrapment compliance.
Question 5: A pool inspection report should categorize a missing GFCI protection for a 120V receptacle within 20 feet of the pool as:
- A safety hazard requiring immediate correction (Correct answer)
- A deficiency to be corrected at the owner's convenience
- A code upgrade item noted for informational purposes only
- An observation requiring further evaluation by an electrician
Correct answer: A safety hazard requiring immediate correction
Missing GFCI protection near a pool is an electric shock drowning risk and is classified as a safety hazard requiring immediate correction in CPI reporting.
Question 6: When photographing a pool during an inspection, which image is most critical to include in the report?
- A photo of every deficiency identified, showing the specific location and condition (Correct answer)
- A wide-angle overview of the backyard for context
- A photo of the pool brand label on the equipment pad
- A photo of the water clarity from the pool edge
Correct answer: A photo of every deficiency identified, showing the specific location and condition
Documenting each deficiency with a photo showing the specific location and condition is essential so clients and repair contractors can clearly understand and locate the problem.
Question 7: An inspector finds a gas pool heater with visible rust streaks on the heat exchanger and evidence of flame rollout above the burner tray. How should this be reported?
- As an immediate safety hazard; the heater should not be operated until repaired by a licensed technician (Correct answer)
- As a routine maintenance item; clean the burner tray and monitor
- As a cosmetic deficiency; surface rust is common on older heaters
- As an informational note; flame rollout is normal during startup
Correct answer: As an immediate safety hazard; the heater should not be operated until repaired by a licensed technician
Flame rollout indicates combustion gases are escaping outside the designed path, which is a fire and CO hazard requiring the heater to be taken out of service immediately.
