If water is pooling at the ends of
splash blocks, you may need to extend a downspout's reach. If you need
to go only a few feet, fit a length of downspout to the elbow of the
existing spout and move the splash block to the end. For longer
distances, dig a shallow trench, line it with gravel and install
flexible plastic drainpipe so that it slopes 1/4 inch per foot toward
its outlet. Connect the pipe to the spout with a special adapter. Cover
it with more gravel, earth, and sod.
