Pump runs but pool circulation is poor and water clarity deteriorates

Safety first: Ensure pump is off before adjusting valves or opening filter.

• Increase speed: On Lowara variable‑speed pumps, increase the programmed filtration speed to improve turnover.
• Extend run time: Adjust the timer so the pump runs long enough to achieve at least one full pool volume turnover per day (often more in heavy use).
• Clean filter: Backwash or clean the filter to restore flow.
• Check hydraulics: Ensure all valves are correctly set for full pool circulation, not bypass or waste.
