Flush Gutters with Water

After removing bulk debris, use a garden hose to flush remaining dirt and small particles through the downspouts. This confirms the entire gutter system drains freely and reveals any hidden clogs or leaking joints.

Steps

1. Remove large debris first by hand or with a scoop -- flushing alone will not clear heavy buildup.
2. Start at the end farthest from the downspout and work toward it, pushing sediment along the trough.
3. Use a high-pressure nozzle for better cleaning force. A standard spray setting is usually insufficient.
4. Watch the downspout outflow. If water backs up or trickles instead of flowing freely, the downspout is clogged -- disconnect the lower section and clear it.

Tips

• Flushing is a finishing step, not a standalone cleaning method for full clogs
• Check gutter seams and end caps for leaks while water is running
• Do this on a dry day so you can clearly see whether water is draining correctly
