Amerimax 4 In. X 12 Ft. Flex-drain Expandable Perforated Drainage Pipe

Available in lengths that expand from 3 Ft. to 12 Ft. and 6 Ft. to 25 Ft. Perforated FLEX-Drain can be used in most drainage applications. The soil-tight fittings are built into the pipe, the pipe holds its shape after it is bent, therefore no other connectors need to be purchased to connect multiple pieces of drain pipe together. Simply dig your trench, lay your FLEX-Drain pipe, and cover it up. FLEX-Drain meets the Corrugated Polyethylene Pipe Association's test for crush resistance.
