Possible Causes
Excessive backpressure from small plumbing, Multiple valves closed simultaneously, Undersized AquaFlo pump for added features, Overly high programmed speed
How to Fix / Troubleshooting
Safety first: Turn off power before adjusting valves if they are hard to reach or near electrical components.
- Open valves gradually: When activating spa or features, open valves slowly to avoid sudden pressure spikes.
- Reduce speed: On variable-speed AquaFlo pumps, program a lower RPM for high-resistance modes like spa jets.
- Monitor filter pressure: Ensure pressure stays within the filter’s safe operating range. If pressure spikes when features are on, adjust valve positions to balance flow.
