In addition to its inherent qualities of beauty, durability and low maintenance, copper's reusability makes it an ideal application in sustainable projects.

Nibco E590250 – Frequently Asked Questions

1) What pipe connections does the Nibco 890 drum trap have on each end?
The 890 drum trap is a C x F configuration: one solder cup (C) that sweats onto copper DWV tube, and one female NPT threaded end. So you can solder into a copper drain line on one side and thread into an NPT fitting on the other, without an adapter.
2) Should I use a drum trap or a standard P-trap on this drain?
A drum trap like the Nibco 890 holds a much larger water seal in a cylindrical body and is cleaned through a threaded cleanout plug on the body, which is why it shows up under tubs and floor drains where a P-trap would be hard to reach or would lose its seal. A P-trap is the normal choice on everyday sink and lavatory waste runs and is accepted by code more broadly. Drum traps are often restricted or prohibited in new work by local plumbing code, so confirm your jurisdiction allows one before specifying it, and use the 890 mainly for repair and replacement of existing drum trap installations.
3) Is the Nibco 890 drum trap copper or brass?
The body is cast bronze, ASTM B584 Alloy C84400, and it is dezincification resistant with material and workmanship per ASME B16.23. It is sold as part of Nibco's copper fitting line and solders to copper DWV tube, but the trap casting itself is bronze, not wrought copper.
4) What does the bottom inlet on the Nibco 890 drum trap mean for how it installs?
Inlet comes in through the bottom of the drum body rather than the side, so the waste arm drops down into the trap and the large water seal sits above it. That orientation suits a trap set below a tub or floor level where the inflow approaches from underneath. The cleanout with plug faces out so you can rod the trap and the connected portion of the drain line without cutting the trap out.
5) Can the Nibco 890 drum trap be used on a commercial job, or is it residential only?
Both. It is listed for commercial plumbing and residential plumbing service, on DWV (drain, waste, vent) systems. It is not a pressure or potable supply fitting, so keep it on drainage only.
6) Do I need to do anything special when soldering a bronze drum trap into a copper DWV line?
Solder the C end as you would any copper DWV joint, but keep heat off the threaded NPT end and remove the cleanout plug before you start so trapped heat and any plug sealant are not an issue. Nibco publishes Copper Fittings Installation Instructions and technical data sheets covering joint prep and heating for these fittings, and those are the reference for the procedure.
