Westlake dwv-d400-030 Dwv Sanitary Tee 3 in Hub Pvc Sch 40

Product Description

The WESTLAKE PIPE FITTINGS dwv-d400-030 is a 3-inch PVC sanitary tee fitting designed for drain, waste, and vent (DWV) systems. All three ends feature hub connections for solvent-cement joining to standard Schedule 40 PVC pipe. Rated for a maximum service temperature of 140 degrees F, this fitting meets ASTM D3311 and ASTM D1866 dimensional standards and carries NSF 14 certification, confirming suitability for potable-water drain applications as well as general DWV service. It is installed by licensed plumbers in residential and light commercial piping systems.

This fitting is used in gravity-flow drain, waste, and vent piping layouts where a branch takeoff is needed from a horizontal run. The sanitary tee configuration allows a vertical or near-vertical branch connection while maintaining proper flow direction. Typical applications include soil stack branch connections, lavatory drain branch connections, and horizontal-to-vertical transitions in Schedule 40 PVC DWV assemblies. It is appropriate for both new construction rough-in and retrofit drain line work.

Key Features

• 3-inch nominal pipe size with all-hub ends for solvent-cement connection
• Schedule 40 wall thickness per ASTM D1866 dimensional standard
• ASTM D3311 compliant — meets standard for DWV plastic fittings
• NSF 14 certified for use in drain, waste, and vent applications
• Maximum service temperature of 140 degrees F
• PVC construction resists corrosion and chemical attack from household drain waste

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 40 PVC DWV piping systems using 3-inch nominal hub-end connections.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) or applicable local code. Shut off water supply and confirm the drain line is depressurized before cutting into existing pipe. Clean and deburr all pipe ends, apply PVC primer, then solvent cement per manufacturer instructions before assembling joints. Do not subject this fitting to pressurized supply service — it is rated for gravity DWV use only.
