Abstract: Drain products/systems and methods for installation are provided for diverting water away from a structure, e.g., a home's foundation. The drain products/systems are designed for use with conventional gutter and downspout systems and are adapted for installation/use at ground level. The disclosed drain products/systems are defined by a base and a side wall that surrounds the base on three sides thereof. The side wall which surrounds the base is typically defined by an inner wall portion, a bridging portion and an outer wall portion. The outer wall portion is advantageously of greater height than the inner wall portion. The difference in height between the outer wall portion and the inner wall portion typically defines a downwardly extending U-shaped portion. The disclosed drain products/systems offer superior flexibility to homeowners and/or contractors/builders, permitting efficient and reliable installation and use in countless terrains and environmental circumstances.
