What It Means
Backup Valve Stuck or Low Flow
Likely Causes
- Backup valve not cycling (stuck open or closed)
- Water flow rate too low to fill bag
- Bag torn or zipper open
- Head float restricting intake
- Debris deflector missing or misaligned
Next Checks
- Listen for backup valve clicking every 3-5 minutes — if silent, replace backup valve
- Check flow rate — bag should inflate visibly while running
- Inspect bag for tears and zipper closure
- Remove and inspect head float — should be buoyant, not waterlogged
- Confirm debris deflector is installed at intake throat
