Our take on the Downspout Adapter Corrugated

The Flex-Drain adapter is a polypropylene fitting that joins a 2"x3" downspout to Flex-Drain, 3" or 4" corrugated pipe, 4" PVC and most other 4" pipe. Its corrugated, flexible body bends to meet pipe at awkward angles, which rigid adapters cannot do, and it is rated for underground burial. It handles up to 70 psi and 150 °F. It suits homeowners extending a downspout into a buried drain line or patching a mismatched connection. Compared with rigid PVC adapters, it trades a straight, glued joint for push-on versatility.
