What is the purpose of backwashing a sand or DE pool filter?
Answer: To remove trapped debris and restore flow rate
Backwashing reverses water flow through the filter to flush out accumulated dirt and debris, restoring its filtration capacity.
What is the recommended total alkalinity range for residential pool water?
Answer: 80–120 ppm
Total alkalinity of 80–120 ppm acts as a pH buffer, preventing rapid pH swings in pool water.
Which chemical is used to raise the pH of pool water?
Answer: Sodium carbonate (soda ash)
Sodium carbonate (soda ash) is the standard chemical added to pool water to increase pH when it falls below the ideal range.
How should pool chemicals be stored in an apartment maintenance facility?
Answer: In a cool, dry, well-ventilated area, separated by chemical type
Pool chemicals must be stored separately by type in a cool, dry, ventilated space to prevent dangerous reactions between incompatible chemicals.
What does a pool's 'turnover rate' refer to?
Answer: The time it takes to circulate the entire pool volume through the filter
Turnover rate is the time required for the pump and filter to circulate and filter the entire volume of pool water once.
What is the primary purpose of a pool skimmer?
