Mueller Streamline PDWVCOUP4 Pvc Dwv Coupling 4 in

Product Description

The MUELLER STREAMLINE PDWVCOUP4 is a 4-inch PVC DWV coupling with hub-by-hub (H x H) end connections, designed for drain, waste, and vent piping systems. This fitting joins two sections of 4-inch PVC pipe in a straight run, making it a standard component in residential and light commercial drain and vent rough-in work. The hub-by-hub configuration accepts solvent-weld connections on both ends, creating a leak-resistant, permanent joint. Licensed plumbers and pipe fitters are the primary installers of this fitting in new construction and remodel applications.

This coupling is suited for 4-inch DWV piping runs in sanitary drain lines, soil stacks, vent stacks, and horizontal drain branches. Its 4-inch size is a common diameter for main drain lines serving toilets, floor drains, and building drains in residential and light commercial plumbing systems. It is appropriate for above-ground DWV applications where PVC schedule and pressure ratings align with IPC and local code requirements.

Key Features

• 4-inch hub-by-hub configuration for straight inline pipe joining
• PVC material provides corrosion resistance in drain and vent service
• Solvent-weld ends create permanent, leak-resistant connections
• Designed for DWV (drain, waste, and vent) service, not pressure applications

Compatibility

Designed as an OEM-style replacement and standard fitting for 4-inch PVC DWV piping systems in residential and light commercial plumbing applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) or applicable local codes. Before cutting into an existing drain line, confirm the system is depressurized and drained. Both pipe ends and fitting hubs must be cleaned, primed, and solvent-cemented using products rated for PVC DWV service. Allow full cure time before restoring flow to the line.
