Sioux Chief 821 Test Plug for Shower Drain

The Sioux Chief 821 Test Plug is a rough-in accessory built to temporarily seal the outlet of a Sioux Chief 821 series shower drain while the drain body is being pressure and water tested, before finish flooring or a shower pan locks the fitting in place. Plumbers set the plug into the drain outlet during the rough-in inspection phase, run their water or air test to confirm the connection holds, then pull the plug once the drain is cleared for final tie-in and trim-out. Keeping the outlet capped during this window also keeps mortar, thin-set, tile debris, and other job-site material from working its way into the drain body while surrounding trades finish the floor. The plug is manufactured in the United States and is supplied 10 EA per carton, a quantity sized for stocking a service truck or a job box on multi-unit new-construction and renovation work.

Key Features

  • Purpose-Built Fit: Sized and configured specifically to plug the outlet of the Sioux Chief 821 shower drain during rough-in, so there is no guesswork matching plug to drain.
  • Test-Ready Seal: Temporarily seals the drain body so the crew can verify the shower drain connection holds water or air pressure before the inspector signs off and finish work proceeds.
  • Debris Protection: Blocks mortar, thin-set, tile debris, and other construction material from entering the drain body while the shower pan, membrane, and finish floor go in around it.
  • Removable When Ready: Designed to be pulled once the drain has passed rough-in inspection and is ready for the shower strainer or finish assembly.
  • Job-Ready Packaging: Supplied 10 EA per carton, a practical quantity for stocking rough-in plumbing trucks, job boxes, and multi-unit projects.
  • Made in the USA: Manufactured in the United States.

Sioux Chief 821-TP – Frequently Asked Questions

1) What does the Sioux Chief 821-TP test plug actually do on a shower drain rough-in?
The 821-TP is a temporary plug that seals the outlet of a Sioux Chief 821 series shower drain so the crew can run a water or air test and prove the connection holds before the inspector signs off. It stays in while the shower pan, membrane and finish floor go in, keeping mortar, thin-set and tile debris out of the drain body, then gets pulled before the strainer or finish assembly goes on.
2) Will the Sioux Chief 821-TP plug fit a shower drain from another manufacturer?
No. The 821-TP is sized and configured for the outlet of the Sioux Chief 821 shower drain specifically, so it is not a general-purpose test plug for other brands or other Sioux Chief drain series. If the drain body in the floor is not an 821, order the test plug matched to that drain instead.
3) Is the Sioux Chief test plug reusable, or is it a one-time cap?
It is meant to come back out. The plug is made to be pulled once the drain has passed rough-in inspection and is ready for the shower strainer or finish assembly, rather than being cut or broken out like a knock-out cap.
4) How many Sioux Chief 821 test plugs come in a carton?
Packaged 10 each per carton, which is a stocking quantity rather than a single piece. That suits a service truck, a job box, or a multi-unit new-construction run where you are testing a dozen bath rough-ins on the same floor.
5) Can I leave the test plug in the drain while the tile setter finishes the floor?
That is one of the reasons to use it. Keeping the outlet capped through the finish-floor window stops mortar, thin-set, tile debris and other job-site material from working into the drain body while the shower pan and membrane go in around it. Pull it once the drain is cleared for final tie-in and trim-out.
6) Is the Sioux Chief 821-TP made in the USA for jobs with domestic sourcing requirements?
Yes, the 821-TP test plug is manufactured in the United States, with country of origin listed as United States. That matters on public and institutional work where domestic-content documentation is part of the submittal package.
