- Pump not running: Verify power connection, on/off switch position, and ensure motor is not overloaded.
- Inconsistent dosing: Inspect tubing for cracks or stiffness and replace if necessary.
- Leaks at fittings: Tighten connections and verify correct tubing size and chemical compatibility.
Maintenance Tip
Inspect the pump tubing and fittings monthly for wear or leaks. Replace the pump tube at least once a year or sooner if it shows signs of fatigue.
