Install Sheer Descent and Place Water Wall
Turn the water wall copper-side down and slip the sheer descent into place, securing it according to the manufacturer's instructions. Slide the last 4" x 4" support piece between the two posts, positioning it so that it serves as a floor for the sheer descent. Attach the support with screws.
Fit the vertical posts into the pre-dug holes by the water feature basin. Make sure the copper wall is centered, with the basin directly in front, before securing into place. Dry-set the posts with dry cement mix.
