Quick Answer
Check a first flush diverter for blockages every 3-6 months to ensure proper function and prevent waterborne contaminants from entering the storage tank.
Importance of Regular Maintenance
Regular maintenance of the first flush diverter is crucial to ensure that it continues to divert the initial flow of water from the roof, removing debris and contaminants that may have accumulated during rainfall events. Without regular checks, the diverter may become clogged, leading to reduced efficiency and potentially even overflowing of the storage tank.
Frequency of Checks
Based on the flow rate of the roof and the amount of debris it collects, it is recommended to check the first flush diverter every 3-6 months. For roofs with a high debris accumulation rate, such as those with overhanging trees or a high number of roof penetrations, checks may need to be performed more frequently. Conversely, roofs with a low debris accumulation rate, such as those with a metal sheeting or a low number of roof penetrations, may only require checks every 6-12 months.
Techniques for Maintenance
When performing maintenance on the first flush diverter, it is essential to follow a few specific techniques to ensure that the device is properly cleaned and functioning correctly. Start by removing the diverter and inspecting its interior for any blockages or debris buildup. Use a soft-bristled brush or a low-pressure hose to gently clean out any debris, taking care not to damage the diverter’s internal components. Once cleaned, reassemble the diverter and test its function to ensure that it is diverting the initial flow of water correctly.
