FLEX-Drain makes French drain installation faster with an expandable, accordion-style perforated pipe that ships compressed at 12 inches but stretches to any length up to 12 feet. Unlike rigid pipe that must be cut and joined, FLEX-Drain simply pulls to your needed length and stays put due to its memory shape. The 4-inch diameter pipe is pre-wrapped in a heavy-duty filter sock to prevent soil infiltration and clogging. Each section connects to the next with slip-lock fittings — no glue or special tools. FLEX-Drain is compatible with NDS, ADS, and standard 4-inch corrugated fittings. Because it bends around curves and obstacles without fittings, it is the fastest solution for draining low spots, downspout extensions, and yard drainage trenches. The complete kit includes the pipe, filter sock, and three couplings.
