- Continue backwashing for 5-10 minutes, or until the water running out of the waste line is clear.
Step 6: Rinse the Filter
- After backwashing, set the valve to the “Rinse” position.
- Run the pump for 30 seconds to 1 minute to flush out any remaining debris.
Step 7: Reset the Valve to Filter Position

Troubleshooting
Problem: Low Pressure During Backwashing
- Check if the garden hose is kinked or obstructed.
- Clean the backwash outlet on the filter.
- Inspect the filter media for signs of clogging.
Problem: Water Not Draining During Backwashing
- Ensure that the main drain and waste valves are fully open.
