Copperfit 1A1699 Abs Dwv Closet Bend 4x3 Inches

Product Description

The COPPERFIT 1A1699 is an ABS DWV closet bend with an integrated test cap, designed to transition toilet drain connections from a 4-inch floor flange down to a 3-inch drain line. This fitting is manufactured from acrylonitrile butadiene styrene (ABS) material, making it lightweight, rigid, and resistant to the corrosive drain-waste-vent environment. The test cap allows the system to be pressure-tested before final connection, a requirement on many new-construction and rough-in inspections. Plumbers use this fitting during rough-in to establish the correct offset and drop for the toilet drain. It weighs 1.19 pounds and fits standard DWV pipe schedules.

This closet bend is suited for residential and light commercial plumbing rough-in work where a 4-inch-to-3-inch reduction is needed at the toilet drain location. It is installed below the subfloor during new construction or remodel rough-in, positioned to align with the toilet flange above and the building drain below. The included test cap simplifies rough-in inspection by allowing the drain system to hold pressure or water during a DWV pressure or flood test without requiring a separate plug.

Key Features

• ABS construction provides lightweight handling and resistance to drain-waste-vent conditions
• 4-inch inlet to 3-inch outlet configuration handles standard residential toilet drain reduction
• Integrated test cap eliminates the need for a separate DWV test plug during rough-in inspections
• Compatible with standard ABS solvent-weld DWV pipe and fittings
• Order increment of 1 allows single-unit purchase for service and repair work

Compatibility

Designed as an OEM-style replacement and new-installation fitting for residential and light commercial ABS DWV drain systems requiring a 4-inch-to-3-inch closet bend at the toilet rough-in location.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) or applicable local code. Solvent-weld ABS fittings require proper ABS cement and primer as specified by local code; do not use PVC cement on ABS fittings. Ensure the drain system is fully depressurized and isolated before cutting into an existing line. The test cap should remain in place only during the inspection phase and must be removed before the toilet flange and fixture are set.
