Draw the guide line: nail a fixed nail from the upper end of the hook down about 30 mm. Draw the guide line of the hook according to the gradient (l% drainage gradient) of 30 mm per 3 m in the direction of the nail to the nozzle.

Determine the length of the pvc rain gutter: A. If the eaves of this section are straight lines, the eaves and gutters are equal in length. B. If the eaves length is longer than the fixed length of the pvc rain gutter, the pvc rain gutter needs to be connected in segments, and the pvc rain gutter at the junction overlaps by 5 cm. C. The length of the pvc rian gutter is longer than that of the eaves if the pvc rain gutter direction has an external turning angle. Every 90 degree angle added, the gutter is 130mm longer than the eaves. For each additional 135 degree angle, the trench is 70 mm longer than the eaves.
