CPI CPI Spa & Hot Tub Specific Requirements 1 — Questions and Answers
Question 1: What is the maximum water temperature recommended for public spa use according to most US health codes?
- 100°F
- 104°F (Correct answer)
- 110°F
- 108°F
Correct answer: 104°F
Most US health codes set the maximum spa water temperature at 104°F to prevent hyperthermia.
Question 2: Which component is required on all spa covers to prevent accidental entrapment or drowning?
- Lock-down straps or locking mechanism (Correct answer)
- Foam insulation core
- UV-resistant vinyl shell
- Reflective surface coating
Correct answer: Lock-down straps or locking mechanism
Spa covers must have lock-down straps or a locking mechanism to prevent unsupervised access, especially by children.
Question 3: What minimum posting requirement applies to spas regarding water temperature and bather time limits?
- No posting is required
- A sign must be posted near the spa entrance (Correct answer)
- A sign must be placed inside the spa basin
- A sign must be visible from 50 feet away
Correct answer: A sign must be posted near the spa entrance
A sign displaying maximum water temperature and recommended maximum bather exposure time must be posted near the spa entrance.
Question 4: How frequently should spa water be completely drained and refilled under typical public facility guidelines?
- Every 30 days
- Based on calculated turnover from bather load and water volume (Correct answer)
- Only when visibly cloudy
- Every 6 months regardless of use
Correct answer: Based on calculated turnover from bather load and water volume
Drain-and-refill intervals are calculated based on bather load and total dissolved solids (TDS) accumulation relative to spa volume.
Question 5: What is the purpose of an air induction system (blower) in a spa?
- To heat the water faster
- To inject air into jets for a bubbling/massaging effect (Correct answer)
- To maintain water clarity by aerating
- To remove surface debris
Correct answer: To inject air into jets for a bubbling/massaging effect
A blower injects air into the jet lines to create a massaging bubble effect for bather comfort.
Question 6: Which condition in a spa jet system should a CPI inspector flag as a deficiency?
- Jets that rotate freely
- Broken or missing jet face covers (Correct answer)
- Jets installed at varying angles
- Jets with adjustable venturi controls
Correct answer: Broken or missing jet face covers
Broken or missing jet face covers can create sharp edges and entrapment hazards, which must be flagged.
