A: No. The piping system is effective at cleansing itself due to the flow patterns developed within the system. There are no moving parts or devices requiring maintenance or replacement.
All roof drains are subject to the same environmental conditions including debris from trees, industrial activity and wildlife activity. Therefore, regular and appropriate roof and gutter maintenance is always recommended.
