The COPPERFIT 1A1717 is an ABS DWV sanitary tee fitting used in drain, waste, and vent piping systems. It features a 2-inch by 2-inch by 1.5-inch configuration, making it suitable for branch connections in residential and light commercial DWV assemblies. The fitting is manufactured from ABS (acrylonitrile butadiene styrene) plastic, which resists corrosion and is compatible with solvent-cement joining methods. Plumbers and pipefitters install this tee during rough-in work to transition a branch line into a vertical or horizontal stack. Its sanitary sweep design promotes proper drainage flow and reduces the risk of blockage at the junction.
This sanitary tee is intended for use in DWV piping systems where a 1.5-inch branch connection meets a 2-inch main run. Typical applications include connecting lavatory drains, utility sink drains, or other 1.5-inch fixture branch lines into a 2-inch waste stack or horizontal drain line. It is appropriate for residential new construction, remodel work, and light commercial plumbing installations where ABS DWV piping is specified or already in use.
Designed as an OEM-style replacement and new-installation fitting for ABS DWV piping systems using standard 2-inch and 1.5-inch schedule pipe and fittings.
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 ensure the drain system is depressurized before cutting into an existing line. Use ABS-approved solvent cement and primer as required by the applicable code; follow the cement manufacturer's cure time before returning the system to service. Orient the sanitary tee so the swept branch entry aligns with the direction of flow to maintain proper drainage.
