FLEX-Drain helps you get the job done faster and easier, with professional grade durability and more versatility than traditional corrugated pipe. Its integrated soil-tight fittings lock securely and stay connected during backfilling. Taping joints is unnecessary. This Perforated FLEX-Drain with sock is 25 ft. long. It's also perfect for applications such as French drains or dispersing water from flower beds, but works even better in locations where surrounding soil or sand is fine and requires filtration or where debris is considerable.
