Downspout Connectors
Connect a downspout to an underground drain line. Flexible PVC slips into place with no clamps or glue, and lifts off when you need to check the line.
Pick by the pipe in the ground
Is your drain line 3″ or 4″? Use a Downspout Connector. If your downspout runs into a larger 6″ pipe at or above grade, use a Universal Downspout Connector: you trace your downspout on top and cut the opening to fit.
Downspout Connectors
For 3″ and 4″ drain pipe. Match your downspout shape and your pipe size.
Into 3″ drain pipe
For 2½″ square downspouts, or 3″ round and 3″ x 2″ rectangular downspouts.
Into 4″ drain pipe
For 3″ x 2″ rectangular downspouts.
- Retail card: PDSC-43
Into 4″ drain pipe
For larger 5″ x 3″ rectangular downspouts.
Fits the pipe you have
The 4″ connectors work with Sch. 40 PVC, ABS, SDR-35 and corrugated drain pipe.
Universal Downspout Connectors
For 6″ pipe. Trace your downspout and cut the opening to fit, even if the downspout is off-center.
6″ cap, fits over the pipe
For pipe that sticks up above ground. Fits over the outside of 6″ PVC and cast iron pipe only. Takes a downspout up to 6″ measured corner to corner.
6″ plug, fits into the pipe
For pipe cut off at grade. Fits inside any pipe with a 6″ inside diameter. Takes a downspout up to 5.75″ measured corner to corner.
How to install
No clamps or glue. Snips or a saw to cut the downspout, and a pencil and utility knife for the Universal.
- Fit the round end to the drain pipe. The DSC-33 slips over the pipe. The DSC-43 and DSC-534 push into it until the flange rests on the rim.
- Cut the downspout to length so it reaches into the connector.
- Push the downspout into the top. No clamps or glue.
- Set the cap over the pipe, or the plug into it.
- Trace around the downspout where it meets the top. It doesn’t need to be centered.
- Cut along the line, then push the downspout through.
Run the line to a storm drain, a pop-up emitter or daylight, away from the house and where local code allows. Don’t connect a downspout to a sanitary sewer or a footing drain.

Common questions
Which connector do I need?
Start with the pipe in the ground. For 3″ or 4″ drain pipe, pick the Downspout Connector that matches your downspout shape. For a 6″ pipe, use the Universal cap if the pipe sticks up above ground, or the plug if it’s cut off at grade.
Do I need clamps or glue?
No. The flexible PVC fits snugly over the downspout and the pipe.
Can I take it off to clean the line?
Yes. Lift the downspout and connector off to look into the line or flush it out with a hose.
Does it keep out debris and pests?
It closes the gap between the downspout and the drain pipe, which helps keep out debris and pests. It doesn’t filter what comes down the downspout, so keep your gutters clean.
Can I connect a downspout to the sewer?
Not to a sanitary sewer. Plumbing codes keep roof water out of sewage lines, and many cities require downspouts to be disconnected from combined sewers. Connect to a storm drain or drain line only where your local code allows.
Is the PDSC-43 the same part?
Yes. PDSC-43 is the retail card version of the DSC-43.
