The ABS DWV double sanitary tee features all hub connections, a flowing sweep to aid in the evacuation of waste and used fluids and two 90-degree side inlets to join two ABS branch lines into a vertical drain pipe. The tee allows for a connection to be made in continuous pipe line and branch out to a different direction. 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 I276250 – Frequently Asked Questions

1) What is the Nibco 5835-9-9 ABS double sanitary tee with side inlets used for?
It's a DWV drainage fitting that ties two horizontal branch lines into a vertical drain stack back to back, plus two 90-degree side inlets for additional branch connections. The sweep on the sanitary pattern helps carry waste down into the stack. It's for drain, waste and vent service only, in both residential and commercial plumbing.
2) What pipe sizes does the Nibco 5835-9-9 double sanitary tee come in?
Two configurations: 3 x 3 x 3 x 3 x 2 x 2 inch (MPN I276250) and 4 x 4 x 4 x 4 x 2 x 2 inch (MPN I276600). In both, the four main openings are the run and branch size and the two side inlets are 2 inch, so it's a reducing fitting that lets you pick up a pair of 2 inch branches off a 3 or 4 inch stack.
3) Are the connections on this Nibco ABS tee hub or threaded?
All openings are hub sockets for solvent cement, hub x hub x hub. You cut the pipe square, prime and cement it in, no threading and no gaskets. It's Schedule 40 sizing, so it takes standard Schedule 40 ABS DWV pipe.
4) Can I connect this ABS tee to existing cast iron or copper drain lines?
Not directly. The Nibco 5835-9-9 is all solvent weld hub, so it only cements to ABS pipe. To tie into steel, copper or cast iron you need transition fittings between the ABS and the other material. ABS DWV can also be joined by threading where a threaded adapter is used.
5) Does this Nibco ABS fitting meet code standards for a plumbing inspection?
It's listed to ASTM D2665, ASTM D3965, ASTM D2661 and D3311, CSA B181.1, NSF/ANSI Standard 14, and NSF U.P. certified. It also carries a UL listing for 94V-0 flammability. Those are the marks an inspector looks for on ABS DWV fittings.
6) What temperature range can ABS DWV fittings handle?
Service range is -40 F to 180 F, which covers normal drainage including hot wastewater from dishwashers and laundry. ABS resists everything from sewage to common household chemicals. One hard limit: never test or use the system with compressed air or other gases, water test only.
7) Should I use a double sanitary tee or two separate sanitary tees on a stack?
The double sanitary tee puts both branch connections at the same elevation on opposite sides of the stack, which is the usual way to serve back to back fixtures such as two bathrooms sharing a wall. Two single sanitary tees would need vertical separation and more stack height. This one adds two 2 inch side inlets as well, so you can pick up additional branches at the same fitting instead of adding another fitting below it.
8) Will this black ABS tee match my existing drain lines?
The fitting is black ABS, the standard color for ABS DWV, so it matches black ABS pipe already in the building. If your existing drainage is white PVC DWV, this is not the same material and should not be solvent cemented to it.
