First Flush Diverter Placement: Where Should It Go?

Installing the First Flush Diverter

To install a first flush diverter, begin by selecting a suitable location on the roof, considering accessibility and ease of maintenance. Typically, this is at the roof edge, 6-12 inches from the gutter downspout, where the initial flow of water is most concentrated. Ensure the diverter is securely attached to the roof or gutter using lag screws, clips, or other suitable fasteners.

Optimizing the First Flush Diverter’s Performance

The first flush diverter’s effectiveness depends on its ability to capture the initial flow of water and divert it away from the storage tank. To optimize performance, consider the following:

• A diverter with a minimum capacity of 1-2 gallons is recommended to ensure adequate capture of the initial flow.
• Position the diverter to receive the maximum amount of initial flow, typically 3-6 inches from the downspout.
• Regularly inspect and clean the diverter to ensure proper function and prevent debris buildup.

Common Misconceptions and Troubleshooting

Some common misconceptions about first flush diverters include:

• Assuming the diverter will capture 100% of the initial flow, which can lead to underestimation of its effectiveness.
• Failure to properly clean and maintain the diverter, leading to reduced performance or premature failure.

To troubleshoot issues with the first flush diverter, inspect the device for blockages or debris buildup, and ensure proper installation and alignment with the gutter and downspout.
