What if you find
a clog in the subsurface drain attached to the downspout? A subsurface drain is a plastic downspout extension that runs underground . It's just one alternative for directing water away from the house. Splash blocks also prevent the downspout from dumping water along the foundation wall. A splash block can be placed under the downspout facing either direction.
To get water further away from the house, it's wise to use a downspout extension. PVC or corrugated plastic connects directly to the downspout and should be extended 10 to 15 feet from the house. The tubing can be placed on top of the soil, but that may interfere with yard maintenance. Or it may be buried just below the surface. Make sure the tubing is placed so that water can drain away from the house. The end of the tubing should always be kept free from foliage and debris that may block the flow of water. Down spout extensions are an inexpensive and effective way to keep your house dry.
