The PVC DWV 45-degree wye features a hub x hub x hub connection and allows for a connection to be made in continuous pipeline and branch out to a different direction. 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 K090250 – Frequently Asked Questions

1) Will the Nibco 4810 PVC DWV wye solvent weld onto Schedule 40 PVC drain pipe?
Yes. The 4810 wye is a Schedule 40 PVC DWV fitting with hub sockets on all three openings, joined by solvent cement. Slip the cut pipe end into the hub, no threading or gasket. All three ports are hubs, so every connection off this fitting is a solvent weld joint into DWV pipe of the matching nominal size.
2) What sizes does the Nibco 4810 45-degree PVC wye come in, including reducing branches?
Straight sizes run 1-1/4, 1-1/2, 2, 3, 4, 6 and 8 inch. Reducing combinations cover 2 x 2 x 1-1/2, 2 x 1-1/2 x 1-1/2, 3 x 3 x 2, 3 x 3 x 1-1/2, 4 x 4 x 3, 4 x 4 x 2, 4 x 4 x 1-1/2, 6 x 6 x 4, 6 x 6 x 3, 8 x 8 x 4 and 8 x 8 x 6. The reducers let you pick up a lav or a 2 inch kitchen branch off a 3 or 4 inch main without adding a bushing at the wye.
3) Can I use the Nibco 4810 PVC wye on a water supply or compressed air line?
No. This is a drain, waste and vent fitting only. Maximum service temperature is 140 F, and it must never be tested or used with compressed air or other gases. Keep it on gravity DWV piping, not pressure water and not air.
4) Does the Nibco 4810 wye meet the standards an inspector will look for on a DWV rough-in?
The fitting is manufactured to ASTM D2665 and D3311, and it is certified to NSF/ANSI Standard 14 and NSF U.P. Certified for use in potable-adjacent drain, waste and vent systems. Those are the markings an inspector checks on the fitting body during rough-in.
5) I need a 1-1/2 inch branch off a 3 inch drain line. Do I need a bushing with this Nibco wye?
No bushing needed. Order the 3 x 3 x 1-1/2 reducing wye, MPN K090750. The run stays 3 inch hub on both ends and the branch hub takes 1-1/2 inch pipe directly. If the branch is 2 inch instead, the 3 x 3 x 2 is K090700.
6) Is this Nibco PVC wye approved for commercial buildings or just houses?
Both. The 4810 is listed for commercial and residential plumbing, and the size range backs that up: 1-1/4 through 8 inch, so it covers a lav branch in an apartment and an 8 inch building drain main in a school or hospital. Standardizing one fitting family across a portfolio is straightforward because the same wye, in the same white PVC, runs the whole size range.
7) What do I need besides the Nibco 4810 wye to make up the joint?
The wye ships as the fitting alone. You supply PVC primer and solvent cement rated for DWV, and the pipe. Since all three ports are hub sockets, there are no gaskets, nuts or threads to buy. On a horizontal branch you will typically also want a 45-degree elbow to bring the branch from the wye back to horizontal.
8) How do I identify the exact Nibco 4810 wye size I need when ordering?
Each size carries its own Nibco part number. Common ones: 1-1/2 inch is K090050, 2 inch is K090250, 3 inch is K090550, 4 inch is K091050, 6 inch is K092600 and 8 inch is K092800. Reducing patterns are read run x run x branch, so 4 x 4 x 2 (K091150) has a 4 inch run with a 2 inch branch.
9) Can I run hot dishwasher or laundry discharge through this PVC DWV wye?
Normal fixture discharge is fine, but the ceiling is 140 F service temperature. Sustained higher-temperature waste, such as a commercial kitchen or lab line running above that, needs a different material. For ordinary residential and light commercial dishwasher, laundry and sink drainage, PVC DWV is what gets specified.
10) Will this PVC wye corrode or scale in a waste line the way cast iron does?
PVC will not rust, scale, pit or corrode, and it holds up to the chemical loads a waste line sees. That is the reason it gets specified over metal on drainage: light, corrosion resistant, and no interior scaling to reduce the bore over time.
