Tried to walk the dog between storms yesterday and got caught in a downpour which yielded unexpected results. I saw something I might otherwise never have known about. When the rain comes down really hard, water backs up out of a downspout elbow, shooting into the air like a fountain (to land in a vulnerable, leak-inducing area) instead of continuing along the long, extended horizontal downspout track* to drain away from the house/foundation. Before I look into wider downspouts and elbows, I'd like to try sealing thoroughly. What will work better, duct tape or gutter sealant?
*Downspout runs the length of the house, about 40 feet (with one additional 90 degree turn besides the elbow) before spilling onto the lawn to run down a hill. This was necessary as the neighbor's property, just a few feet away, slopes down towards my house. No room to effectively release water without navigating the length of the house.- posted
