Such a simple solution, just a regular PVC adapter that can prevent tons of headaches in the future.

What happens here

Take the 'Y' downspout cleanout adapter, which is typically made of PVC as seen in the video, and insert the cut ends of the downspout into its top and bottom openings. Ensure the fit is snug. To secure the connections, use self-tapping screws or rivets (depending on the downspout material and personal preference) on all four joints (top and bottom connections on both sides). Finally, twist the removable cap onto the exposed cleanout branch of the 'Y' adapter until it is hand-tight.

Goal: Integrate the 'Y' adapter into the downspout system.
