  Charlotte GoldenSep 8, 2025
  If you're experiencing low or no chlorine residual in your CircuPool Water Filtration System after a recent installation, ensure the system is running in sync with the circulation pump and double-check all connections. If the system is not getting enough voltage, have a professional test the power source and ensure the correct connection. Run the system at maximum output.

Why is the Flow LED red on my CircuPool Water Filtration Systems?

  Timothy MunozSep 10, 2025
  If the Flow LED is red on your CircuPool Water Filtration System, check the water level, look for pump cavitation, air, or blockages in the plumbing, and inspect all valves and seals. Clean the filters and strainers, and make sure there's at least a 25-30 GPM flow rate. Also, verify the correct orientation, ensure the cable is plugged in, and that there's 6-12" of straight pipe before the flow switch.

  If you notice a water leak in your CircuPool Water Filtration System, make sure the O-rings are clean and in good condition. Inspect the threads for damage and ensure each screws back on without resistance. Unscrew the cell, carefully align it, and use a hand cable to press and hold it in place with the corresponding notch on the Cell while screwing the Cell head’s cap hand-tight.

  Joseph CarrollSep 16, 2025
  If the Low Water Temp LED is red on your CircuPool Water Filtration System, no action is needed. The system has deactivated due to low water temperatures, which extends the system’s lifespan. The unit will begin working again once seasonal temperatures rise. Check cable connections.
