Ipex 40962 Pvc Downspout Adapter 3x4x4 Sdr 35

Product Description

The IPEX 40962 is a PVC downspout adapter rated for SDR 35 service, designed to transition rainwater runoff from a building downspout into an underground storm drainage system. This straight adapter connects a 3-inch inlet to a 4-inch by 4-inch outlet configuration using a solvent-weld bell and spigot joint. It is manufactured from PVC, making it resistant to corrosion and ground chemical exposure. Licensed plumbers and drainage contractors install this fitting during site drainage, downspout tie-in, and storm sewer connection work.

This adapter is used in residential and light commercial applications where roof drainage must be directed into a buried SDR 35 storm drain line. The straight configuration allows a direct in-line connection from the downspout to the underground piping without offset. It is suited for new construction and retrofit drainage projects where a positive, sealed connection between the vertical downspout and the horizontal storm line is required.

Key Features

• PVC construction resists corrosion and chemical degradation in buried installations
• SDR 35 wall rating meets common storm sewer application standards
• Straight downspout configuration for direct in-line connection
• Solvent-weld bell and spigot joint for secure, leak-resistant assembly
• 3-inch by 4-inch by 4-inch sizing bridges downspout and main drain line transitions

Compatibility

Designed as an OEM-style fitting for SDR 35 PVC storm drainage systems requiring a straight downspout adapter transition from a 3-inch inlet to a 4-inch storm drain line.

Installation Notes

Installation is performed by licensed plumbers or drainage contractors following local plumbing and storm drainage codes. Shut off and cap the existing drain line before cutting in or connecting any new fittings. Solvent-weld joints require approved PVC primer and cement applied per manufacturer instructions and must be allowed to cure fully before backfilling. Verify local code requirements for SDR 35 storm drain applications before installation.
