Nibco E540350 – Frequently Asked Questions

1) What sizes does the Nibco 880 DWV P-trap come in?
The Nibco 880 cast P-trap is made in 1-1/2 inch (MPN E540300) and 2 inch (MPN E540350) pipe sizes. Those are the two DWV sizes it covers, so a lavatory or sink run on 1-1/2 inch tube and a shower, floor or bar sink run on 2 inch tube are both handled.
2) How do the two ends of this Nibco 880 P-trap connect, solder or slip joint?
It is a C x SJ trap: one end is a copper solder cup (C) that sweats onto DWV copper tube, and the other is a slip joint (SJ) that takes a slip nut and washer, typically to the fixture tailpiece. So you solder the drain side and mechanically join the fixture side, which lets you pull the fixture later without heat.
3) Does this P-trap have a cleanout, and why does that matter?
Yes, the 880 has a cleanout with a plug at the bottom of the bend. Pull the plug and you can rod or snake the trap and the branch without cutting the soldered joint or dropping the trap out of the wall, which is the reason spec writers call for a cleanout trap in commercial restrooms and janitor rooms.
4) What is the Nibco 880 trap made of, and will it hold up better than a plastic or tubular trap?
It is cast bronze, ASTM B584 alloy C84400, and dezincification resistant. That is a different class of part than a chrome tubular or PVC trap: it is a soldered-in cast fitting for permanent DWV work, so it suits commercial and institutional installations where a thin tubular trap gets crushed or corroded. Workmanship is per ASME B16.23.
5) Can I use this Nibco trap on a pressure or water supply line?
No. The 880 is a DWV fitting for drain, waste and vent service only. It is a trap, so it holds a water seal against sewer gas at atmospheric pressure, and it should never be installed on a pressurized supply or hydronic line. Use pressure-rated copper fittings for those.
6) Do I need anything besides the trap to finish the connection?
The 880 ships with its cleanout plug. For the solder end you supply DWV copper tube, flux and solder; for the slip joint end you supply the slip nut and washer sized to the fixture tailpiece. Nibco publishes copper fitting installation instructions covering joint prep and soldering.
7) Is the Nibco 880 P-trap approved for commercial jobs or just residential?
Both. Nibco lists the 880 for commercial and residential plumbing systems, which is why it turns up in multi-family and institutional restroom groups as well as single-family work. Copper fittings are made in an ISO 9001 certified facility.
8) Is there a reason to pick copper over plastic for a trap on a green or sustainable project?
Copper is reusable at end of life, which is the argument Nibco makes for its use on sustainable projects, along with durability and low maintenance. A cast bronze trap can be recovered and recycled rather than landfilled the way a plastic trap is.
