The ABS DWV 90-degree street water closet elbow features a spigot x hub connection and is specially designed to connect to the bottom of the closet flange. Please refer to NIBCO technical data sheets and catalogs for engineering and installation information. Acrylonitrile-Butadiene-Styrene (ABS) is resistant to a wide variety of materials ranging from sewage to commercial household chemical formulations and can be exposed to a wide temperature span. ABS is lightweight, safe to handle and easy to install. ABS DWV is joined by solvent cementing or threading and can easily be connected to steel, copper, or cast iron through the use of transition fittings. NIBCO® plastic fittings are backed by a 5-year limited warranty. Because of its longstanding reputation for innovation and precision in design and manufacturing, NIBCO is the preferred brand in the industry.

Nibco I058270 – Frequently Asked Questions
1) What is a closet elbow used for on a toilet drain?
A closet elbow makes the 90 degree turn under a water closet. The Nibco 5807-2-CL is an ABS DWV 90 degree street closet elbow, meaning the spigot end goes up into the bottom of the closet flange and the hub end takes the branch or stack line. It is a 1/4 bend fitting for drain, waste and vent service, in Schedule 40 ABS.
2) What is the difference between the capped and uncapped Nibco closet elbow?
Two versions are sold: the capped closet elbow (MPN I058270) and the version with no cap (MPN I058250). The cap is a test or cleanout closure on the fitting, so if your inspection requires the drain to be plugged and pressure or water tested before the toilet is set, order the capped one. If you are tying straight in with no test requirement, the no-cap version is the one you want.
3) How do you join this ABS closet elbow, and can I thread it instead?
It is a solvent weld fitting. ABS DWV is joined with ABS solvent cement, or threaded where a threaded fitting is used, and it ties into steel, copper or cast iron lines through transition fittings. Do not try to cement ABS to PVC without the correct transition method.
4) Will this street closet elbow fit into a standard closet flange?
Yes, that is what the street (spigot) end is for. The spigot outside diameter matches the pipe it replaces, so it slips directly into the socket on the bottom of a closet flange without an extra length of pipe. The other end is a hub that accepts Schedule 40 ABS DWV pipe.
5) Does this Nibco closet elbow meet code for a commercial building?
The ABS DWV fittings carry CSA B181.1, ASTM D2665, ASTM D3965, ASTM D2661 and D3311, UL Listed 94V-0, NSF/ANSI Standard 14, and are NSF U.P. Certified. They are rated for both commercial and residential plumbing systems. Check your local plumbing code on whether ABS is accepted in your jurisdiction, since some areas require PVC DWV instead.
6) What temperature range can ABS DWV fittings handle, and can I use them on a pressure line?
Service range is -40 F to 180 F, which covers normal household and commercial waste discharge including dishwasher and laundry drainage. It is a drainage fitting only. Never test or use ABS DWV with compressed air or other gases.
7) Is this closet elbow black ABS or white PVC?
Black. It is ABS (acrylonitrile butadiene styrene), so it will match existing black ABS drain lines, and it takes ABS cement rather than PVC cement. If your building is plumbed in white PVC DWV, use a PVC closet elbow or a proper ABS-to-PVC transition.
8) Will ABS hold up to drain cleaners and sewage in a rental property?
ABS resists a wide range of materials from sewage through common commercial and household chemical formulations, which is why it is used across multi-family and residential waste lines. It is also light enough to handle overhead in a joist bay without support rigging.
