Westlake Pipe Fittings dwv-d104-015 Dwv Trap Adapter 1-1/2 in

Product Description

The WESTLAKE PIPE FITTINGS dwv-d104-015 is a 1-1/2 inch PVC female trap adapter designed for drain, waste, and vent (DWV) piping systems. It connects hub-end pipe on one side to a slip-joint connection on the other, and includes a plastic nut and washer for a secure, serviceable seal. Rated Schedule 40/STD, this fitting meets standard wall-thickness requirements for residential and light commercial DWV applications. Plumbers and pipefitters install this adapter where a P-trap or S-trap connects to a branch drain line, allowing the trap arm to be removed without cutting pipe.

This adapter is used in residential and light commercial DWV drain lines, typically under sinks, lavatories, and similar fixtures. The hub end accepts standard 1-1/2 inch PVC pipe with solvent cement, while the slip-joint end accommodates a trap arm without a permanent bond, making future access and trap cleaning straightforward. It is well suited for new rough-in work and repair or replacement of existing drain connections in kitchen, bathroom, and utility installations.

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-1/2 inch Schedule 40 PVC DWV drain systems in residential and light commercial plumbing.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the applicable plumbing code, such as the IPC or local jurisdiction amendments. Shut off the water supply and clear the drain line before beginning work. The hub end requires PVC solvent cement applied per the cement manufacturer instructions; the slip-joint end is hand-tightened with the included plastic nut and washer and does not require solvent welding. Do not overtighten the plastic nut, as this can crack the nut or distort the washer and cause leaks.
