The PVC DWV two-way cleanout tee features a hub x hub x hub connection and provides a means for clearing potential clogs in certain portions of the drainage system. Please refer to NIBCO technical data sheets and catalogs for engineering and installation information. Polyvinyl chloride (PVC) is the most frequently specified of all thermoplastic materials because of its light weight, durability, and cost-effectiveness. PVC DWV is easy to install and is joined by solvent cementing or threading. PVC fittings exhibit high corrosion and chemical resistance and will not rust, scale, pit or corrode. 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 K138060 – Frequently Asked Questions
1) What size pipe does the Nibco 4811-C PVC DWV cleanout tee fit?
The 4811-C two-way cleanout tee comes in 3 inch and 4 inch, both straight size, so all three hubs match the run. The 3 inch is MPN K138060 and the 4 inch is K138070. Both are Schedule 40 DWV, which is what standard PVC drain, waste and vent pipe is sized to, so a 3 inch tee takes 3 inch DWV pipe on the run and the branch alike.
2) Can the Nibco 4811-C PVC cleanout tee be used on a pressure or water supply line?
No. This is a DWV fitting, for drain, waste and vent only, and it is not rated for pressure service. Do not use it on potable supply, irrigation, or any pressurized line, and never test or use it with compressed air or other gases. For pressure work you need a pressure-rated PVC or CPVC fitting instead.
3) Does the Nibco 4811-C cleanout tee meet plumbing code for a commercial building?
It is made to ASTM D2665 and D3311, and it is certified to NSF/ANSI Standard 14 and NSF U.P. Certified. Those are the DWV fitting standards inspectors look for on both commercial and residential drainage, and the tee is listed for use in either.
4) What is a two-way cleanout tee actually for, and do I need one on a drain line?
A two-way cleanout tee gives you a rodding point into the drainage system so a clog in that section of line can be cleared without cutting pipe. Two-way means the opening lets you snake in either direction along the run instead of only downstream. It is the fitting you set where a buried or concealed drain run needs a serviceable access point, typically at a change of direction or at the base of a stack.
5) How hot can the waste water get through a PVC DWV cleanout tee?
Maximum service temperature is 140 degrees F. That covers ordinary sink, tub, laundry and floor drain waste, but it rules out lines carrying sustained higher-temperature discharge, such as commercial dishwashers or boiler blowdown, where a higher-temperature material is called for.
6) Will the Nibco 4811-C match the white PVC drain pipe already in my building?
Yes, the fitting is white PVC, the standard color for Schedule 40 DWV pipe and fittings, so it blends with existing white PVC drainage runs. If your existing drain line is black ABS, this is not the fitting to use, ABS and PVC are different materials and are not solvent cemented to one another with ordinary PVC cement.
7) Do I need to order a cleanout plug separately with the Nibco 4811-C tee?
Plan on it. The 4811-C is the tee body itself, hub x hub x hub in Schedule 40 DWV, and the cleanout opening has to be closed off in service. Match the plug and adapter to the tee size you order, 3 inch for the K138060 or 4 inch for the K138070, along with PVC primer and solvent cement for the three hub joints.
8) Will a PVC cleanout tee corrode or rust in a buried or wet drain line?
PVC does not rust, scale, pit or corrode, and it holds up against the chemicals that move through a waste line, which is why it is the usual pick for buried and concealed drainage over metal. That matters most on a cleanout, since it is the fitting you may need to open years after it went in.
