Sioux Chief 864-W3PU2 3" Little Max Round Floor Sink with 1/2 Grate

The Sioux Chief 864-W3PU2 Little Max Floor Sink is a 3" rough-in drainage fitting designed for installation beneath fixtures, equipment, or floor openings where indirect waste needs to be collected and routed to the drain line. This compact floor sink features a 1/2 round grate configuration, making it a practical choice for plumbers and contractors working in tight mechanical rooms, commercial kitchens, or utility areas where a full-size floor sink body won't fit. As a member of the Sioux Chief Little Max series, this unit is built for behind-the-wall and under-floor rough-in work, not decorative finish applications. The 3" size references the fitting's connection sizing for tie-in to the building drainage system, and the included grate is intended to catch debris before it enters the drain while still allowing water to pass through efficiently.

Key Features

  • Trade Size: 3" nominal size for rough-in connection to the drainage line.
  • Compact "Little Max" Design: Space-saving floor sink body suited to installations where a standard floor sink footprint is impractical.
  • 1/2 Round Grate Included: Round grate configuration helps capture debris at the drain opening while permitting water flow.
  • Indirect Waste Receptor: Functions as a floor-mounted drain receptor for indirect waste connections in commercial and light-commercial settings.
  • Manufacturer Part Number 864-W3PU2: Sioux Chief factory part number for accurate ordering and cross-reference.
  • Single-Unit Packaging: Supplied 1 EA per package for straightforward job-site stocking.

Sioux Chief 864-W3PU2 – Frequently Asked Questions

1) What size drain connection does the Sioux Chief 864-W3PU2 Little Max floor sink tie into?
The 864-W3PU2 Little Max floor sink is a 3 inch nominal unit, so it ties into a 3 inch branch on the building drainage system. If your rough-in is already stubbed for a 2 inch line, this is not the body to order.
2) Can I use a Little Max floor sink for indirect waste from a commercial kitchen sink or ice machine?
That is what it is for. The 864-W3PU2 works as a floor-mounted receptor for indirect waste, catching discharge from fixtures or equipment above and routing it to the drain line. Typical uses include commercial kitchen indirect waste, equipment drip and condensate collection, and mechanical or utility room floor drainage.
3) What does the 1/2 grate on the 864-W3PU2 mean?
It means a half round grate configuration sits over the drain opening rather than a full grate. The open half lets you run a drain line or pipe discharge directly into the receptor while the grated half still catches debris and passes water. If you need the whole opening covered, order a full grate version instead.
4) Is the Little Max floor sink small enough for a tight mechanical room where a standard floor sink won't fit?
Yes, that is the point of the Little Max series. It is a compact floor sink body intended for spots where a standard full-size floor sink footprint is impractical, such as tight mechanical rooms, kitchens, and utility areas.
5) Does the Sioux Chief 864-W3PU2 come with the grate, or do I order it separately?
The grate is included. The 864-W3PU2 ships as one assembly with the 1/2 round grate, supplied 1 each per package.
6) Is this a finished-floor decorative drain or a rough-in part?
Rough-in. The Little Max floor sink is built for behind-the-wall and under-floor rough-in work, not decorative finish applications. If the drain will be visible in a finished space where appearance matters, specify a finish-grade drain instead.
7) How many Sioux Chief 864-W3PU2 floor sinks come in a package?
One. The 864-W3PU2 is supplied 1 EA per package, so order per opening rather than by the carton.
