Product Details

This 4 in. x 12 ft. pipe has spaced slits that allow water to drain in stages. The drain pipe is ideal for groundwater drainage like French drains or for dispersing water from flower beds. FLEX-Drain helps you get the job done faster and easier with professional-grade polypropylene construction for impressive durability. Additionally, an easy-to-transport design and seamless extrusion technology make the FLEX-Drain more versatile than a traditional corrugated pipe. Flexible and expandable, FLEX-Drain easily bends around any obstacle. The FLEX-Drain holds its shape during installation and with a simple snap, its integrated fittings lock securely and stay connected during backfilling. With the FLEX-Drain, taping joints is unnecessary adding to the convenience of the product. More than just pipe, FLEX-Drain is a complete drainage solution system that's widely compatible with virtually all traditional 3 in. and 4 in. corrugated pipes and 4 in. PVC. Technologically superior, the FLEX-Drain is made with no-break copolymers and exceeds all applicable ASTM crush standards.
  • To avoid clogging the slits, use this pipe where surrounding soil is coarse soil where debris is minimal
  • Proprietary peak and valley design offers greater surface area and a 30% higher load-bearing rating than standard corrugated pipe
  • Made for tight places and curvy spaces
  • Easy to transport
  • High-quality polypropylene construction for durability
  • Made with no-break copolymers for professional grade strength and integrity
  • Incorporates seamless extrusion technology
  • Expands from 41 in. to 12 ft.
  • Adapts to 3 in. and 4 in. corrugated pipe and 4 in. PVC using Flex Drain Universal Pipe Connector (not included)
  • Use to divert water away from foundations and for other applications that involve diverting water
  • Exceeds ASTM standards
  • Return Policy

Q:When putting behind a retaining wall how much gravel can be put on top without crushing
by|Apr 10, 2022
1 Answer
Answer This Question

A:  Everything I read in the item description asserts that this will perform as good or better than traditional corrugated 4in. drain. As commonly as I've seen the traditional stuff used in retaining wall drainage with gravel, this should perform fine.

      Q:Can this be used for Radon mitigation in crawl space?
      by|Feb 3, 2022
      2 Answers
      Answer This Question

      A:  I would not. Radon mitigation requires removing the affected air from the crawl space. The two times I have paid for a Radon mitigation system to be installed, they have always used enclosed pipe.

          Performed as expected. We used this to pull rain water away from the house. It slipped easily over the gutter end and allowed us to direct the flow across the yard away from the house.

          Used it for a french drain. It's perforated and it's exactly what I needed. It's durable and sturdy, and has held up well during the recent rainstorms here in Florida.

          A Quick and easy drain solution.
          The quick and easy way to install a drainage system. It's easiest with two people to stretch it out with one on each end and pull to expand the pipe. The nice thing about this flexable pipe is it lays in the ditch even if the ditch is not straight, un-like 10' long sections of solid pipe. The pipe has small holes in it all along the way so water can leach into the ground along the leingth of the pipe.
