The WESTLAKE PIPE FITTINGS dwv-d300-030 is a 3-inch PVC 90-degree elbow designed for drain, waste, and vent (DWV) piping systems. Built to Schedule 40/STD wall thickness, this fitting provides a quarter-bend direction change in gravity-flow drain lines. Both ends use a hub (socket) connection for solvent-cement joining to standard PVC DWV pipe. Plumbers and pipefitters install this fitting in residential and light commercial drain systems where a 90-degree change of direction is required on a 3-inch line.
This fitting is used in DWV applications including branch drains, stack connections, and horizontal-to-vertical transitions in Schedule 40 PVC drain systems. Its hub-by-hub end configuration accepts 3-inch PVC pipe on both sides, making it suited for new construction rough-in and repair work in residential and commercial plumbing installations.
Designed as an OEM-style replacement and standard fitting for 3-inch Schedule 40 PVC DWV piping systems in residential and light commercial plumbing applications.
Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off water supply and ensure the line is drained before cutting into an existing system. Clean and dry all mating surfaces before applying solvent cement, and follow the cement manufacturer's cure time before pressure-testing the line. Do not use this fitting in pressure piping applications outside of its DWV rating.
