Sioux Chief 883-PT 3" x 4" PVC Closet Flange with Test Knockout

The Sioux Chief 883-PT is a 3" x 4" PVC closet flange engineered for toilet (water closet) rough-in installations. Molded from durable PVC for direct compatibility with PVC drain-waste-vent piping, this flange features a Test Knockout (TKO) design that lets the installing plumber use the fitting as a temporary test cap during rough-in inspection, then knock it out to open the waste line for the final toilet connection. Manufactured in the United States, the dual 3" x 4" hub sizing lets installers mate the same flange to either 3" or 4" PVC drain pipe, which cuts down on the number of flange SKUs a rough-in crew has to stock for mixed pipe sizes on a job site. Each unit ships 25 EA per case for distributor and contractor restocking.

Key Features

  • Trade Size: 3" x 4" hub connection lets one flange accept either 3" or 4" PVC drain pipe, reducing the number of part numbers needed on the truck.
  • Durable PVC Construction: Molded PVC body resists corrosion from wastewater exposure and solvent-welds directly into PVC DWV pipe runs.
  • Test Knockout (TKO) Design: A removable knockout plug lets the flange double as a temporary test cap while the rough-in is pressure or water tested, then knocks out cleanly to open the waste line for the toilet connection without swapping fittings.
  • Closet Flange Type: Purpose-built to anchor a toilet (water closet) to the floor drain pipe, giving the closet bolts a solid mounting point and supporting the wax ring seal.
  • Country of Origin: Manufactured in the United States.
  • Packaging: Supplied 25 EA per case for stocking distributors and rough-in crews.

Why Sioux Chief?

Sioux Chief backs the 883-PT with solid PVC construction and a practical Test Knockout design that lets one flange handle rough-in inspection and the final toilet hookup without a fitting change.

Sioux Chief 883-PT – Frequently Asked Questions

1) Will the Sioux Chief 883-PT closet flange fit 3 inch or 4 inch PVC drain pipe?
Both. The 883-PT is a 3 x 4 hub closet flange, so the same fitting accepts either 3 inch or 4 inch PVC DWV pipe. That is why rough-in crews stock it on mixed jobs instead of carrying separate 3 inch and 4 inch flanges.
2) What does the TKO (test knockout) on a closet flange actually do during rough-in?
It lets one fitting cover two steps. The 883-PT's knockout plug seals the waste line so the flange works as a temporary test cap while the rough-in is tested, then you knock the plug out to open the line for the toilet connection. No swapping fittings between inspection and final hookup.
3) How does the 883-PT connect to the drain pipe, glue or push fit?
It's a molded PVC hub flange, so it solvent-welds directly into a PVC DWV run with PVC cement. Being PVC throughout, it also resists corrosion from wastewater. If your drain stack is cast iron or ABS, this is not the flange for that joint.
4) Does a closet flange like this come with the closet bolts and wax ring?
The 883-PT is the flange itself. It gives the closet bolts a solid anchor point and supports the wax ring seal, but the bolts, wax ring, and floor fasteners are separate items you add to the order to finish the toilet set.
5) Can I use the 883-PT on a commercial bathroom remodel, not just new construction?
Both apply. The 883-PT is used for toilet rough-in in residential and commercial bathrooms, on new construction and remodel work, anywhere the drain is PVC DWV pipe at 3 or 4 inches.
6) What part number should I order for a 3 x 4 PVC closet flange with a test cap from Sioux Chief?
Sioux Chief part number 883-PT. One model covers the 3 x 4 PVC hub with the test knockout built in, so there is no separate option to pick.
7) How is the Sioux Chief 883-PT packaged for distributor stock?
Twenty-five each per case. That case quantity suits stocking distributors and rough-in crews doing multiple toilet sets, rather than a single-unit counter sale.
8) Is the Sioux Chief 883-PT made in the USA?
Yes, the 883-PT closet flange is manufactured in the United States, which matters on public and institutional work carrying domestic-content requirements.
