Westlake Pipe Fittings dwv-d448-040 Dwv Cleanout 4 Inch Pvc

Product Description

The WESTLAKE PIPE FITTINGS dwv-d448-040 is a 4-inch hub-end PVC two-way cleanout fitting designed for drain, waste, and vent (DWV) systems. It provides access points for drain line inspection and clearing in non-pressurized sanitary drainage piping. The fitting is manufactured from PVC and meets ASTM D 3311, ASTM 1866, and ASTM 1784 dimensional and material standards. It carries NSF 14 certification, confirming it meets requirements for plastic piping system components used in drain and waste applications. Licensed plumbers install this fitting during rough-in or as a retrofit cleanout in residential and light commercial drain systems.

This cleanout fitting is suited for non-pressurized DWV installations including residential drain and waste lines, light commercial sanitary drainage, and vent piping assemblies. The hub connection style accepts standard 4-inch PVC DWV pipe with solvent-cement joints. It is appropriate for horizontal runs, vertical stacks, and accessible cleanout locations per local plumbing code requirements. The two-way configuration allows rodding or jetting from either direction, making it a practical choice for drain lines that may require periodic maintenance access.
