What is diatomaceous earth (DE) used for in pool filtration?
Answer: A fossil-based powder that coats filter grids to trap fine particles
DE is made from the fossilized remains of microscopic diatoms; its porous structure can filter particles as small as 2–5 microns.
What does SVRS stand for in pool safety equipment?
Answer: Safety Vacuum Release System
A Safety Vacuum Release System automatically detects a blocked drain and shuts off the pump or releases suction to prevent entrapment.
What is the purpose of a hair and lint strainer (pump pot) in the recirculation system?
Answer: To catch large debris before it reaches and damages the pump impeller
The hair and lint strainer (pump pot) collects hair, lint, leaves, and other debris that passed through the skimmer to protect the pump.
When sizing a circulation pump, which factor is most important?
Answer: The required flow rate (GPM) and total dynamic head (TDH)
A pump must be matched to both the required flow rate (GPM) for turnover and the TDH of the piping system to operate efficiently.
What is the function of a pool booster pump?
Answer: To increase pressure for an automatic pool cleaner or water features
A booster pump provides additional pressure specifically for pressure-side automatic cleaners or water features that require higher pressure than the main pump delivers.
What is the recommended approach when a pool pump loses prime?
Answer: Check for air leaks on the suction side, refill the pump pot, and reprime
A pump loses prime when air enters the suction side; the fix is to identify and seal air leaks, fill the pump housing with water, and restart the pump.
