The PVC DWV trap adapter features a spigot x slip joint with chrome nut connection and provides a means for adapting a solvent weld connection to a slip join connection. 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 K014570 – Frequently Asked Questions
1) What does a Nibco 4801 PVC trap adapter actually do in a drain line?
The Nibco 4801 trap adapter bridges a solvent weld connection over to a slip joint connection. One end is a spigot that cements into a PVC DWV socket, the other is a slip joint end with a chrome nut, so you can land a chrome or plastic trap arm into a glued PVC drain stub. It is white PVC and is used in both residential and commercial plumbing.
2) Which sizes does the Nibco 4801 trap adapter come in, and which one do I need for a 1-1/4 inch trap?
Two sizes: a straight 1-1/2 inch, and a reducing 1-1/2 inch x 1-1/4 inch. If your PVC drain stub is 1-1/2 inch and the trap arm is 1-1/4 inch chrome tubing (common on older lavatory work), take the 1-1/2 x 1-1/4, Nibco K014580. For a 1-1/2 inch trap throughout, take K014570.
3) Will the spigot end of this Nibco trap adapter glue into Schedule 40 PVC DWV pipe?
Yes. The 4801 is a Schedule 40 PVC DWV fitting, so the spigot end solvent cements into a standard Schedule 40 PVC DWV socket or hub of the matching size. Joining is by solvent cementing; PVC DWV can also be threaded where the fitting provides it.
4) Can I use a PVC DWV trap adapter on a hot water or pressure line?
No. This is a drain, waste and vent fitting only, with a maximum service temperature of 140 degrees F, and it must never be tested or used with compressed air or other gases. It is not a pressure fitting and it is not for water supply.
5) Does this Nibco trap adapter meet code for a commercial job?
The 4801 PVC DWV trap adapter is made to ASTM D2665, is certified to NSF/ANSI Standard 14, and carries NSF U.P. certification. Those are the listings an inspector or spec writer typically looks for on plastic DWV fittings.
6) Does the Nibco 4801 trap adapter include the slip joint nut and washer?
The chrome slip joint nut is part of the fitting; the end connection is specified as spigot by slip joint with chrome nut. Plan on solvent cement and primer for the glued end, and confirm you have the slip joint washer sized to the tubing you are landing in it.
7) Should I use a trap adapter or a glued PVC trap on a lavatory rough-in?
Use a trap adapter when the trap has to come apart for cleaning or when you are tying chrome or plastic slip joint tubing into a cemented PVC drain. A fully solvent welded trap is permanent and cannot be broken loose for a snake or a P-trap swap. The 4801 gives you the removable slip joint on one side while the drain side stays cemented Schedule 40 PVC.
8) Will a PVC trap adapter corrode or scale in a waste line?
PVC does not rust, scale, pit or corrode, and it resists chemicals well, which is why it is the common choice for drain, waste and vent work in both residential and commercial buildings. Keep it inside the 140 degree F service limit.
