Westlake Pipe Fittings dwv-d112-040 Dwv Cleanout Adapter 4 Inch

Product Description

The WESTLAKE PIPE FITTINGS dwv-d112-040 is a 4-inch PVC DWV cleanout adapter supplied with a matching cleanout plug. The adapter connects using a spigot (SP) inlet and a female pipe thread (FPT) outlet, allowing the cleanout plug to thread securely into the fitting. Both the adapter and the raised-head plug are manufactured from PVC, making this a complete two-piece cleanout assembly ready for installation in drain, waste, and vent piping systems. Licensed plumbers and pipefitters install this fitting during rough-in and service work where accessible cleanout points are required by code.

This cleanout adapter and plug assembly is used in residential and light commercial DWV piping systems. The 4-inch nominal pipe size suits main drain lines and building drain applications. The spigot end inserts into a hub fitting or coupling in the pipeline, while the FPT opening accepts the threaded cleanout plug, providing a serviceable access point for drain cleaning and inspection without cutting into the line.

Compatibility

Designed as an OEM-style replacement and new-installation fitting for 4-inch PVC DWV drain, waste, and vent piping systems.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable plumbing codes such as the IPC or UPC. Shut off water supply and verify the line is depressurized and drained before cutting into an existing drain line. Use the appropriate PVC primer and solvent cement rated for DWV applications when making the spigot joint. The threaded cleanout plug should be snugged by hand and then tightened with a wrench to ensure a leak-free seal without over-stressing the threads.
