Description
PVC SDR 35 Downspout Adapter (Downspout x Sewer Hub, H x H)
PVC SDR 35 Downspout Adapters provide a direct transition from compatible roof downspouts to SDR 35 sewer and drainage piping for efficient stormwater management.
Featuring a downspout hub on one end and an SDR 35 sewer hub on the opposite end, this adapter is designed to connect above-ground roof drainage to underground stormwater piping. The dual-hub configuration allows each side to accept its corresponding component while providing a compact transition between different drainage profiles. Constructed from durable PVC, the fitting offers resistance to corrosion, moisture, and outdoor environmental exposure for dependable use in residential, commercial, and municipal drainage systems.

Connection Configuration
Downspout Hub
The downspout-side hub is designed to accept the corresponding compatible downspout connection and provide the transition from the building's roof drainage system.
SDR 35 Sewer Hub
The sewer-side hub accepts compatible SDR 35 PVC pipe, allowing runoff to continue into an underground stormwater or drainage line.
Downspout Adapter Design
This adapter creates a dedicated transition between a roof downspout and round SDR 35 sewer piping.
The downspout side is shaped to accept the corresponding drainage connection, while the sewer hub transitions the flow into compatible underground SDR 35 PVC pipe.
By combining both connection types into one fitting, the adapter helps simplify the transition point and can reduce the need for multiple intermediate fittings.

Construction Details
Manufactured from durable PVC, this downspout adapter is designed for long-term use in exterior and underground drainage environments.
The material provides resistance to corrosion, moisture, soil conditions, and many environmental exposures encountered in stormwater applications.
The molded hub connections are designed to provide proper fit with the corresponding downspout connection and compatible SDR 35 PVC sewer pipe.
Installation
Verify the downspout dimensions and SDR 35 sewer pipe size before installation.
Confirm which end of the fitting is intended for the downspout and which end is the SDR 35 sewer hub.
Dry-fit the complete assembly before final installation to confirm alignment, downspout position, pipe engagement, and drainage direction.
Cut the mating SDR 35 pipe square and remove burrs or debris that could interfere with proper insertion.
Clean and prepare solvent-weld surfaces according to accepted PVC installation procedures where solvent welding is required.
Install the downspout connection using the method appropriate for the specific downspout configuration and secure the SDR 35 side using compatible PVC joining materials as required by the manufacturer.
Maintain proper slope and alignment so roof runoff can drain freely into the underground piping system.
Allow any solvent-welded joints to cure according to the solvent cement manufacturer's recommendations before backfilling or placing the system into service.
Our piping specialists can help review your downspout dimensions, SDR 35 pipe size, connection configuration, and stormwater drainage layout before you order.

What is a PVC SDR 35 downspout adapter used for?
It is used to transition roof downspout drainage into compatible SDR 35 PVC underground stormwater or drainage piping.
What does Downspout x Sewer Hub mean?
It means one side is designed for the corresponding downspout connection while the opposite side is a sewer hub designed to receive compatible SDR 35 PVC pipe.
What does H x H mean?
H x H means Hub x Hub. Both sides use hub-style connections, although each hub is designed for a different type of mating component.
Are both hubs the same shape or size?
Not necessarily. The downspout-side hub is designed for the corresponding downspout profile, while the sewer-side hub is designed for compatible SDR 35 PVC pipe.
Can this adapter connect a downspout directly to underground pipe?
Yes. That is its primary function: providing a transition from above-ground roof drainage to compatible underground SDR 35 piping.
Is this fitting intended for stormwater applications?
Yes. The supplied product information identifies stormwater management and roof drainage as primary applications.
Can it be installed underground?
Yes. The SDR 35 side is intended for integration with underground sewer or drainage piping.
Is this fitting intended for pressure service?
No. It is intended for gravity-flow, non-pressure stormwater and drainage applications.
Does the SDR 35 side use solvent cement?
The supplied product information identifies the fitting as using a solvent-weld design. Use compatible PVC joining materials and follow the manufacturer's instructions.
Why should I verify the downspout dimensions?
Downspouts are available in different profiles and sizes. Confirming the actual dimensions helps ensure the adapter matches the intended downspout.
Should the underground pipe maintain slope?
Yes. Proper slope and alignment help gravity-flow drainage systems move roof runoff efficiently away from the building.
What should I verify before ordering?
Confirm the downspout size and profile, SDR 35 sewer pipe size, connection configuration, and compatibility with the intended stormwater drainage system.
