12 Reasons why the health inspector will close your pool - CORRECT ANSWER-1.
pump filter not working for more than an hour
2. main drain is not visible
3. chemical readings out of range
4. no pool operator (15 minute grace period)
5. no lifeguard or cpr certs present
6. water is below the skimmer line
7. danger to the public
8. chlorinator is not working
9. health inspector is not allowed in
10. bathrooms + drains not working
11. flow rate is too low
12. no phone (landline)
Measuring records as the CPO - CORRECT ANSWER-Operator must test the water for
Cl and pH every hour, and Total Alkalinity, Calcium Hardness and Cyanuric Acid once
per week. Records must be maintained on site and available for at least 2 years at the
pool and 3 years total.
5 Factors of Water Balance - CORRECT ANSWER-pH, Total Alkalinity, Calcium
Hardness, Temperature, and total dissolved liquids
Corrosive water - CORRECT ANSWER-pH is too low, dissolves everything it contacts
scaling water - CORRECT ANSWER-pH it too high, mineral deposits on walls or pipes
Regulated pH range - CORRECT ANSWER-7.2-7.8
pH reading is tested with Phenol Red
To lower pH, - CORRECT ANSWER-add muriatic acid
To raise the pH, - CORRECT ANSWER-add sodium carbonate (Soda Ash)
2. sodium bisulfate
3. carbon dioxide
Total Alkalinity - CORRECT ANSWER-represents the amount of carbonates,
bicarbonates, and hydroxides in a solution - you want this to be high, because the pH
resists changes in fluctuating
pH Bounce - CORRECT ANSWER-low alkalinity
Regulated Total Alkalinity range - CORRECT ANSWER-60-180 ppm ideal goal is
100ppm
