Sioux Chief 860-3P FAT MAX PVC Floor Drain with Grate, 3"

The Sioux Chief 860-3P FAT MAX floor drain is a 3" PVC drain body with grate engineered for rough-in installations where a low-profile, solidly anchored drain is required. Built with an anchor flange for a secure set and a PVC solvent weld connection, this floor drain is designed to tie directly into PVC drain-waste-vent piping during new construction or renovation work. The FAT MAX series low profile design helps installers maintain floor height clearances in tight rough-in conditions while still delivering a durable, code-ready connection point for floor-level drainage.

Key Features

  • Trade Size: 3" outlet for standard floor drain rough-in applications.
  • Low Profile Design: Features an anchor flange that provides a solid, stable installation in the floor assembly.
  • Durable Construction: Molded PVC body and grate resist corrosion common to cast metal drains in wet, below-floor environments.
  • Connection Type: ABS or PVC solvent weld connection allows the drain to be joined directly to PVC drain-waste-vent piping.
  • Grate Included: Ships complete with a drain grate for finished floor-level protection against debris.

Sioux Chief 860-3P – Frequently Asked Questions

1) Will the Sioux Chief 860-3P floor drain connect to 3 inch PVC DWV pipe?
Yes. The 860-3P is a 3 inch drain body with a solvent weld outlet, so it glues directly onto 3 inch PVC drain-waste-vent pipe. No gaskets, no clamps, no threaded adapter. The description also notes the connection works for ABS or PVC solvent weld, so you are joining with cement rather than mechanically coupling it.
2) Does the Sioux Chief 860-3P come with a grate, or do I order that separately?
The grate ships with it. The 860-3P is sold as a drain body plus grate, and the grate is molded PVC like the body, so there is no separate strainer to buy to finish the floor.
3) I am tight on floor height above the slab. Is the FAT MAX 860-3P a low profile drain?
Yes, low profile is the point of the FAT MAX series. It is designed to keep floor height clearance in tight rough-in conditions, and it uses an anchor flange to lock the body solidly into the floor assembly rather than a tall riser arrangement.
4) Is the Sioux Chief 860-3P suitable for a remodel where I am replacing an existing floor drain?
It is listed for renovation and remodel drain replacement as well as new construction, but the outlet is a 3 inch solvent weld socket. That means the existing stub you are tying into needs to be 3 inch plastic pipe you can cement to, or you need a transition fitting ahead of the drain. If the old drain sits on cast iron or a hub, plan the adapter into the job.
5) How many floor drains are in a pack of Sioux Chief 860-3P?
Four each per pack. If you are roughing in a single opening that is three more than you need, so plan the buy around multi-unit jobs or shop stock.
6) Will a PVC floor drain hold up better than a cast iron one in a wet below-floor install?
That is the tradeoff the 860-3P is built around. The body and grate are molded PVC, which does not rust or pit the way cast metal does in constantly wet, below-floor conditions. Cast iron still wins where you need heavy traffic load capacity or a metal finish at the floor surface; for residential and commercial rough-in on PVC DWV, the plastic body ties in with cement and removes the corrosion problem.
7) What is the exact part number to order the 3 inch PVC FAT MAX floor drain?
Sioux Chief 860-3P. That is the manufacturer part number for the 3 inch PVC FAT MAX floor drain with grate; the -3P suffix reads as the 3 inch PVC configuration.
8) What does the anchor flange on the Sioux Chief 860-3P actually do during the pour?
It gives the drain body something to grip in the floor assembly so the drain stays put and set square instead of floating or shifting while the floor goes in. For a plumber setting drains ahead of a slab or topping pour, that is the difference between a flush grate and one you have to fight at finish.
9) Is the Sioux Chief 860-3P made in the USA?
Yes, country of origin on the 860-3P is the United States, which matters if you are buying against a domestic preference requirement on a public or institutional project.
