How To Modify A Diverter For Different Rainfall Intensity?

Adjusting the Diverter Angle

When dealing with varying rainfall intensity, the angle of the diverter’s intake can greatly impact water flow. A more acute angle can increase water flow during heavy rainfall, while a shallower angle can reduce flow during light rainfall. For optimal performance, adjust the angle to around 15-20 degrees, allowing the water to flow smoothly into the storage tank.

Adding a Manual Override

To further adapt to different rainfall rates, consider adding a manual override to the diverter system. This can be achieved by installing a small valve or switch that allows the user to control the flow of water into the storage tank. For example, you can add a 10mm gate valve with a handle that can be easily opened or closed to adjust the flow rate. This feature is particularly useful during heavy rainfall when the storage tank may be filling up too quickly.

Variable Flow Control

Another option is to install a variable flow control device, such as a float valve or a pressure switch, that can automatically adjust the flow rate based on the rainfall intensity. For example, a float valve can be set to open at a certain water level and close when the level reaches a predetermined threshold, allowing for more precise control over the flow rate. This feature is particularly useful in areas with highly variable rainfall patterns.
