The answer to 'how to maintain drainage system' is to regularly inspect, clean, and repair your home's drainage system to prevent clogs and ensure proper water flow. This includes checking gutters, downspouts, and underground drainage pipes for any blockages or damage, and addressing issues promptly to avoid water damage to your home's foundation and landscaping.
Start by visually inspecting your gutters and downspouts for leaves, twigs, and other debris that can clog the system. Use a gutter scoop or trowel to remove any buildup, then flush the system with a garden hose to ensure proper water flow. Check that downspouts are securely attached and directing water at least 6 feet away from your home's foundation. If you have underground drainage pipes, use a plumber's snake or high-pressure water jet to clear any clogs.
