  • Our take on the Downspout Adapters

    The FLEX-Drain downspout adapter connects a 3 in. x 4 in. downspout to 4 in. corrugated pipe. It snaps onto FLEX-Drain fittings with integrated soil-tight joints, so you don't have to tape seams before backfilling. It also mates with most traditional 3 in. and 4 in. corrugated pipe and 4 in. PVC. It is made from no-break copolymers that meet ASTM crush standards, which puts it above flimsier corrugated connectors. It suits homeowners and landscapers routing roof runoff away from a foundation.

    About the Downspout Adapters

    This adapter joins a 3 in. x 4 in. downspout to a 4 in. corrugated pipe. It is part of the FLEX-Drain system, a drainage solution that is compatible with virtually all traditional 3 in. and 4 in. corrugated pipe and 4 in. PVC.

    FLEX-Drain is flexible, bendable and expandable. It bends around obstacles and holds its shape during installation. Its integrated soil-tight fittings lock with a simple snap and stay connected during back-filling. Taping joints is not necessary.

    The system is made with no-break copolymers and exceeds all applicable ASTM crush standards.

    Questions and answers

    What does this adapter connect?
    It joins a 3 in. x 4 in. downspout to 4 in. corrugated pipe. The downspout end takes the rectangular outlet; the other end takes the round corrugated pipe.
    Do I need to tape the joints?
    No. The integrated fittings snap together and are soil-tight, so taping is not required before backfilling.
    Will it fit standard corrugated pipe?
    It is made to work with virtually all traditional 3 in. and 4 in. corrugated pipe and 4 in. PVC, not just FLEX-Drain parts.
    Is it strong enough to bury?
    The no-break copolymer body exceeds applicable ASTM crush standards and is designed to hold its shape and stay connected during backfill.
    Does it bend around obstacles?
    The adapter itself is rigid; the flexibility comes from FLEX-Drain pipe it connects to, which bends and holds shape during installation.
