Hayward PowerFlo pump runs but water appears cloudy or dirty despite circulation.

Safety first: Turn off the pump before adjusting valves or opening the filter.

• Verify valve position: Ensure the multiport or diverter valve is set to FILTER, not RECIRCULATE or BYPASS.
• Clean or replace filter media: Backwash sand/DE filters or clean/replace cartridges as needed.
• Increase run time: Run the PowerFlo pump long enough each day to achieve at least one full turnover of pool volume (often 8–12 hours, depending on pool size and pump flow).
• Check filter sizing: If the filter is significantly undersized for the PowerFlo’s flow, consider upgrading the filter to improve clarity.
