Mueller Streamline PDWVBENDSPH4 90 Degree Street Elbow

Product Description

The MUELLER STREAMLINE PDWVBENDSPH4 is a 4-inch 90-degree street elbow configured with a spigot inlet and a hub outlet. This fitting changes flow direction by 90 degrees in a drain, waste, and vent (DWV) piping system. The spigot end inserts directly into a hub fitting, eliminating the need for an additional coupling and reducing the total number of joints in the run. Licensed plumbers install this type of fitting during rough-in on residential and light commercial DWV systems.

This street elbow is suited for horizontal and vertical DWV applications where a 90-degree direction change is required in a 4-inch line. The 4-inch size is commonly used for main drain lines, closet bends, and building drain transitions. The spigot-by-hub configuration allows it to connect directly to standard hub fittings without an intermediate coupling, which is useful in tight rough-in conditions where minimizing stack height or run length matters.

Key Features

• 90-degree street elbow geometry changes flow direction without an added coupling
• Spigot inlet inserts directly into a standard hub fitting for a compact joint
• Hub outlet accepts a standard spigot or pipe end for downstream connection
• 4-inch size suited for main drain, closet, and building drain applications
• DWV configuration designed for gravity-flow drain, waste, and vent service

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 4-inch residential and commercial DWV piping systems using standard spigot and hub connections.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the applicable plumbing code, such as the IPC or UPC. Shut off water supply and ensure the line is drained before modifying any drain or waste piping. Solvent-cement joints require proper surface preparation, correct primer, and cement rated for the pipe material. Allow full cure time before restoring flow or concealing the installation behind walls or under slabs.
