Mueller Streamline DWVPTRAP112 Dwv P-trap 1.5 in Cast

Product Description

The MUELLER STREAMLINE DWVPTRAP112 is a 1-1/2 inch cast copper DWV P-trap configured with copper-to-copper (C x C) sweat connections. P-traps in drain-waste-vent systems create a water seal that blocks sewer gases from entering occupied spaces. This fitting is designed for permanent installation in drain lines behind sinks, lavatories, and similar fixtures. Licensed plumbers install this fitting using standard sweat-soldering methods during new construction or fixture replacement. The cast construction provides consistent wall thickness and reliable joint integrity at both inlet and outlet ends.

This P-trap is used in residential and light commercial DWV piping systems where a sweat-connect fitting is required. Typical applications include under-sink drain assemblies, lavatory rough-in, and other 1-1/2 inch fixture drain connections. The C x C configuration requires copper pipe on both sides of the trap, making it suitable for all-copper drain systems rather than hybrid plastic-to-copper assemblies.

Key Features

• 1-1/2 inch nominal size fits standard lavatory and sink drain lines
• C x C sweat connections for all-copper DWV installations
• Cast copper construction delivers consistent wall thickness and joint strength
• P-trap configuration maintains water seal to block sewer gas intrusion
• Conforms to DWV system fitting requirements for drain-waste-vent applications

Compatibility

Designed as an OEM-style sweat-connect replacement fitting for 1-1/2 inch copper DWV drain systems in residential and light commercial plumbing applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and drain the line before cutting into any existing drain piping. Clean and flux all joint surfaces thoroughly before soldering, and allow joints to cool completely before restoring flow. Do not use this fitting on pressurized supply lines.
