REVIEW QUESTIONS |
GUARANTEED ACCURATE
ANSWERS
12 Reasons why the health inspector will close your pool - ACCURATE
ANSWERS✔✔ 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 - ACCURATE ANSWERS✔✔ 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 - ACCURATE ANSWERS✔✔ pH, Total
Alkalinity, Calcium Hardness, Temperature, and total dissolved liquids
Corrosive water - ACCURATE ANSWERS✔✔ pH is too low, dissolves
everything it contacts
scaling water - ACCURATE ANSWERS✔✔ pH it too high, mineral
deposits on walls or pipes
Regulated pH range - ACCURATE ANSWERS✔✔ 7.2-7.8
pH reading is tested with Phenol Red
To lower pH, - ACCURATE ANSWERS✔✔ add muriatic acid
To raise the pH, - ACCURATE ANSWERS✔✔ add sodium carbonate
(Soda Ash)
2. sodium bisulfate
3. carbon dioxide
Total Alkalinity - ACCURATE ANSWERS✔✔ 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 - ACCURATE ANSWERS✔✔ low alkalinity
