Mueller Streamline K270770 Dwv Reducing Double Sanitary Tee

Product Description

The MUELLER STREAMLINE K270770 is a reducing double sanitary tee designed for drain, waste, and vent (DWV) piping systems. This fitting features a 3 x 2 x 3 x 2 inch nominal configuration with hub end connections and is manufactured from Schedule 40 PVC. It allows two branch inlets to connect into a single run while maintaining proper downward flow direction, which is critical in gravity-fed DWV systems. Licensed plumbers install this fitting during rough-in on residential and light commercial drain systems. Domestic manufacture meets standard quality expectations for code-compliant DWV work.

This fitting is used in residential and light commercial plumbing applications where reducing branch connections are required in a DWV stack or horizontal drain run. The double sanitary tee configuration accommodates two 2-inch branch lines entering a 3-inch main run. Hub end connections accept solvent-welded PVC pipe, making it compatible with standard Schedule 40 PVC DWV piping systems. It is well suited for bathroom groupings, laundry connections, and similar multi-fixture drain configurations during new construction or remodel rough-in work.

Key Features

• Reducing double sanitary tee accepts two 2-inch branch inlets on a 3-inch main run
• Hub end style connections for solvent-weld installation with standard PVC primer and cement
• Schedule 40 wall thickness meets standard DWV pressure and load requirements
• PVC construction resists corrosion and chemical degradation common in drain service
• Domestic manufacture for consistent dimensional compliance with ASTM standards

Compatibility

Designed as an OEM-style replacement and new-installation fitting for Schedule 40 PVC DWV piping systems using hub-end solvent-weld connections in residential and light commercial plumbing.

Installation Notes

Installation must be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and ensure the drain system is clear before cutting into an existing line. Use appropriate PVC primer and solvent cement rated for DWV service, and allow full cure time before restoring flow. Sanitary tees must be installed with the curved sweep oriented in the direction of flow — do not install in an upside-down or reverse orientation.
