There are two types of filters commonly used in rainwater harvesting systems. If the tank discharges into the ground via a soakaway, a basket filter is typically used. Homeowners are advised to open the manhole cover, remove the basket filter, empty the debris into a compost bin, and then replace it back into the tank. It is generally recommended to clean the basket filter every two months, but the frequency may vary depending on the property’s location and surrounding trees.
For stainless steel self-cleaning filters, which are connected to a storm network rather than a soakaway, the buildup is not as long. It is usually recommended to clean these filters every six months. However, homeowners will gain an understanding of the specific cleaning frequency based on their system’s performance over time.
It is also recommended to visually check the filter once a month to ensure its proper functioning. This can be done by opening the manhole cover and inspecting the water levels and the cleanliness of the filter. If cleaning is required, the filter can be easily accessed and lifted using the handle on top.
