The MUELLER STREAMLINE PDWVSANT332 is a PVC DWV sanitary tee fitting designed for drain, waste, and vent applications in residential and light commercial plumbing systems. This fitting connects a 3-inch main line to a 3-inch run with a 2-inch branch outlet, all in a hub by hub by hub (H x H x H) configuration. The sanitary tee geometry promotes proper directional flow and is compatible with solvent-weld PVC pipe. Licensed plumbers and pipefitters install this type of fitting during rough-in work on drain and vent stacks.
This sanitary tee is suited for gravity-flow drain, waste, and vent piping in residential new construction and remodel projects, as well as light commercial plumbing rough-ins. The 3 x 3 x 2 inch configuration is commonly used where a 2-inch branch line, such as a lavatory or utility drain, ties into a 3-inch main stack or horizontal drain run. All three hub connections accept standard Schedule 40 PVC pipe and are joined using PVC primer and solvent cement.
Designed as an OEM-style replacement and new-installation fitting for residential and light commercial PVC DWV drain, waste, and vent piping systems using 3-inch and 2-inch Schedule 40 pipe.
Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) or applicable local code. Shut off the water supply and ensure the drain system is depressurized before cutting into existing lines. Clean all pipe and hub surfaces, apply approved PVC primer, then solvent cement per manufacturer instructions before assembly. Sanitary tees must be oriented correctly for flow direction and are not approved for use as a wye in horizontal drain applications where code prohibits it.
