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.

Nibco K009120 – Frequently Asked Questions
1) What does the Nibco 4800-SD adapter actually connect?
It ties PVC DWV pipe into sewer and drain pipe. One end is a DWV hub (socket) and the other is a sewer and drain socket, so it is the transition fitting you use where a building drain in Schedule 40 DWV meets S&D pipe going out to the yard line. It is offered in a 3 inch by 4 inch size, making it a reducing adapter as well as a transition.
2) Is the 4800-SD glued or does it use a gasket?
Solvent cemented. Both ends are sockets, and Nibco PVC DWV fittings are joined by solvent cementing or threading, so you prime and cement it the same way you would any other DWV socket joint. There is no rubber gasket or clamp involved.
3) Will this adapter pass inspection on a commercial job?
The 4800-SD is made to ASTM D2852 and is NSF/ANSI Standard 14 and NSF U.P. Certified, which is the listing most inspectors look for on drain, waste and vent fittings. It is catalogued for both commercial and residential plumbing systems.
4) Can I run hot waste through a PVC sewer and drain adapter?
Keep it under 140 degrees F. That is the maximum service temperature for this PVC fitting, which covers normal sanitary drainage including a dishwasher or washing machine discharge that has cooled in the line. Continuous high temperature discharge, like a commercial kitchen or boiler blowdown, needs a different material.
5) Can I air test a drain line with this PVC fitting in it?
No. Nibco states plainly not to test or use these PVC fittings with compressed air or other gases. Use a water test on the DWV system instead.
6) Can I use the Nibco 4800-SD on a pressure water line?
No. It is a drain, waste and vent fitting only, non-pressure gravity drainage. For supply or any pressurized service you need a pressure-rated fitting, not a DWV adapter.
7) What part number do I order for the 3 inch by 4 inch version?
The 3 inch by 4 inch Nibco 4800-SD sewer and drain adapter is manufacturer part number K009120. The 3 inch side is the DWV hub and the 4 inch side takes sewer and drain pipe.
8) Is the 3 x 4 sewer and drain adapter white or the usual green S&D color?
White. It is a PVC DWV fitting in standard white, so it matches the DWV pipe on the building side even though the other end takes sewer and drain pipe.
