Quick Answer
For effective filtering of leaves and debris in diverters, use a 100-micron filter, maintain a 1-2 inch water flow, and ensure the diverter is designed for rainwater harvesting or first flush systems.
Choosing the Right Filter
When selecting a filter for your diverter, consider its micron rating and durability. For leaves and debris, a 100-micron filter is the minimum recommended. This rating will catch most of the larger particles, including leaves and twigs. However, for more severe weather conditions, consider a 50-micron or even 25-micron filter. Keep in mind that finer filters may require more frequent cleaning or replacement.
Maintaining Optimal Water Flow
Adequate water flow is crucial for efficient filtering. Ensure the diverter is designed to handle the rainwater flow rate, typically 1-2 gallons per minute (GPM). This will prevent clogging and allow the filter to function correctly. If your diverter is too small, consider upgrading to a larger model or installing a flow restrictor to regulate the water flow.
First Flush and Leaf Accumulation
In first flush systems, it’s essential to maintain the diverter’s effectiveness in filtering leaves and debris. Regularly inspect the filter and diverter for blockages. Clean or replace the filter as needed. In severe cases, consider installing a separate leaf trap or mesh screen to capture larger debris before it reaches the filter. This will help prevent clogging and maintain the integrity of the first flush system.
