Our take on the Advanced Drainage Systems 4-1/4 in. Barb X 3 in. D Barb Polyethylene Downspout Adapter

This is a high-density polyethylene adapter that joins a 4 in. x 3 in. downspout to 4 in. singlewall corrugated drain pipe. The 4-1/4 in. barbed end slips over the downspout and the 3 in. barbed end snaps inside the pipe for a friction-fit connection. It is lead-free, ANSI certified and rated for underground use, with a 150°F maximum temperature. It suits contractors and homeowners running gutter water into buried drainage, where a molded HDPE fitting outlasts thin sheet-metal or PVC adapters.

Questions and answers

Will this fit my downspout?
The 4-1/4 in. barbed end is sized to slip over a 4 in. x 3 in. downspout. Measure your downspout outlet before buying; a different size needs a different adapter.
What pipe does the other end connect to?
The 3 in. barbed end snaps inside 4 in. singlewall corrugated drain pipe. It is not made for smooth-wall PVC or Schedule 40 pipe.
Can it be buried?
Yes. It is rated for underground use and made of HDPE, which resists rot and corrosion in soil.
Do I need glue or clamps?
No glue is required; the barbs hold by friction. A screw or clamp at the downspout joint adds security where the pipe may be bumped.
Is it safe for drinking water?
No. It is lead-free but not NSF listed, so use it for drainage only, not potable water lines.
