Nibco E595250 – Frequently Asked Questions

1) What size pipe does the Nibco 891 drum trap connect to?
The Nibco 891 swivel drum trap is offered in a 1-1/2" x 3" x 6" configuration, MPN E595250. The 1-1/2 inch figure is the inlet/outlet connection, with the 3 x 6 describing the drum body itself. Both ends are solder cups (C x C), so they slip over 1-1/2 inch copper DWV tube and are sweated in place.
2) Is the Nibco 891 drum trap solder-joint or threaded?
Both ends of the trap body are solder cups, listed as C x C, so the tube connections are sweated with solder, not threaded. The cleanout is a separate threaded plug that screws into the drum so you can open it for rodding without cutting the joints apart.
3) What is a drum trap used for instead of a regular P-trap?
A drum trap holds a much larger volume of water than a P-trap, so the seal is harder to siphon or evaporate away, and it can catch heavier debris off a tub or floor drain. The Nibco 891 is a DWV drain, waste and vent fitting that maintains that water seal to keep sewer gas out of the building, and the cleanout plug lets you clear a clog in that section of the drain line. Where local code no longer permits drum traps on new work, a standard P-trap is the fitting to use; drum traps are most often bought for repair or replacement of an existing installation.
4) What is the Nibco 891 drum trap made of, and will it hold up in aggressive water?
It is a cast bronze body, ASTM B584 Alloy C84400, and it is dezincification resistant. That matters on water chemistry that strips zinc out of ordinary brass. Material and workmanship follow ASME B16.23.
5) Can I use the 891 drum trap on a commercial job, or is it residential only?
Both. Nibco lists the 891 for commercial plumbing and residential plumbing, on DWV drain, waste and vent service. It is not a pressure or supply fitting.
6) What does the swivel feature on this drum trap do for the install?
The swivel lets you rotate the trap connections to line up with the inlet and outlet runs rather than forcing the piping to meet a fixed orientation. On a tight tub or floor-drain rough-in that is usually what saves you a fitting or two. Confirm the cleanout ends up facing an accessible direction before you sweat the joints.
