Westlake dwv-d800-422 Dwv Pvc Closet Flange 4x3 Inch

Product Description

The WESTLAKE PIPE FITTINGS dwv-d800-422 is a 4-inch by 3-inch DWV PVC closet flange fitting with a hub end connection. It is used to secure a toilet to the drain pipe and subfloor in residential and light commercial plumbing systems. Made from PVC, this flange is rated for drain, waste, and vent applications and meets the dimensional and material requirements that licensed plumbers expect in a code-compliant rough-in installation. The hub end accepts standard 3-inch pipe for the drain connection while the 4-inch flange ring seats flush to the finished floor surface.

This closet flange is suited for new construction and remodel work in residential bathrooms and light commercial restrooms. It installs in DWV systems where a 3-inch drain line terminates at the toilet rough-in location. The fitting is compatible with solvent-weld PVC pipe and works with standard wax ring and closet bolt hardware to complete the toilet setting process.
