Link the pipe to the gutter-– Slip the new pipe into the seamless gutter outlet, securing it with the appropriate bracket or clamp. Tighten up screws simply enough to hold the pipe without deforming it.
Add an elbow or splash block-– At the bottom, attach an elbow to turn water away from the structure, or location a splash block to distribute runoff.
Check the system-– Run water through the seamless gutter (using a hose) to validate smooth flow and check for leakages at joints.
