Sioux Chief 852 Series Adjustable ABS Floor Cleanout

The Sioux Chief 852 Series Adjustable Floor Cleanout is a rough-in drain-waste-vent access fitting built for jobs requiring a serviceable cleanout at the finished floor line. Available with MIP (male iron pipe) connections in 3" and 4" trade sizes, this family is molded from ABS plastic for direct compatibility with ABS DWV piping systems commonly used in residential and light commercial construction. The cleanout head adjusts to the finished floor elevation, simplifying coordination between rough-in and finish stages, and every model in this family ships with a polypropylene cleanout plug plus a lift-out cover offered in round or square styles to suit the rough-in opening or finish preference on the jobsite.

Key Features

  • Trade Size: Available in 3" and 4" MIP connections to match the drain line size required for the installation.
  • Durable Construction: Molded ABS body for use on ABS DWV piping systems, resistant to the corrosion that affects metal cleanout bodies.
  • Adjustable Design: The cleanout head adjusts to accommodate the finished floor height, simplifying rough-in-to-finish coordination across every model in this family.
  • Threaded MIP Connection: Male iron pipe threads adapt directly to any standard FIP (female iron pipe) adapter, giving installers flexibility on the drain side of the connection.
  • Round & Square Lift-Out Cover: Ships with both round and square lift-out cover options so the installer can match the opening or finish surface at the point of service.
  • Polypropylene Cleanout Plug: Included plug seals the cleanout access point and can be removed for servicing or snaking the drain line.

Technical Specifications

  • Material: ABS body with polypropylene cleanout plug
  • Trade Size Range: 3" - 4" MIP
  • Cover Style: Round & square lift-out cover
  • Connection: Threaded MIP (male iron pipe)

Typical Applications

  • Residential and Light Commercial DWV Rough-In
  • Floor-Level Cleanout Access for Drain Lines
  • New Construction Floor Drain Service Points
  • Renovation Projects Requiring Finished-Floor Height Adjustment
  • ABS DWV Piping Systems

Why Sioux Chief?

Sioux Chief builds rough-in plumbing components for the realities of the jobsite, and the 852 Series adjustable floor cleanout family reflects that with a design that adapts to finished floor height and a dual cover option that gives installers flexibility without needing to stock multiple part numbers.

Whether the project calls for a round or square finish surface, the 852 Series gives plumbing contractors a single, adaptable solution for floor cleanout rough-in across residential and light commercial applications.

Sioux Chief 852-3LNR – Frequently Asked Questions

1) Will the Sioux Chief 852 floor cleanout thread onto my ABS drain line?
The 852 Series cleanout is molded ABS with a threaded MIP (male iron pipe) outlet, so it does not solvent-weld directly to ABS pipe. It threads into any standard FIP (female iron pipe) adapter, which is what you glue to the ABS DWV line. Sizes are 3 inch and 4 inch MIP to match the drain.
2) Do I order the round or the square cover on a 852 Series floor cleanout?
Cover shape is part of the part number, so pick it when you order. The 3 inch comes either way: 852-3LNR with a round lift-out cover, 852-3LNQ with a square one. The 4 inch is 852-4LNR, round cover. Square suits a tiled or formed square opening; round suits a cored or sleeved opening.
3) How does an adjustable floor cleanout handle an unknown finished floor thickness?
The 852 Series head adjusts up or down to the finished floor elevation, so the body can be set during rough-in before the slab topping, tile, or flooring goes down, then brought flush at finish. That is the point of an adjustable cleanout over a fixed-height one: you are not guessing the finish buildup on the rough-in day.
4) Is there a square cover version of the 4 inch Sioux Chief 852 cleanout?
In 4 inch MIP the 852 Series is offered as 852-4LNR with a round lift-out cover. The square lift-out cover comes on the 3 inch size, part 852-3LNQ. If the finished opening has to be square, size the rough-in around the 3 inch body.
5) Can I snake the drain through this cleanout after the floor is finished?
Yes. The lift-out cover comes off at the floor surface and the included polypropylene cleanout plug unthreads, opening the 3 inch or 4 inch drain line for rodding or snaking. The plug reseals the access point afterward.
6) Is an ABS cleanout body acceptable, or should I use cast iron?
ABS is the right choice when the drain line itself is ABS DWV, which is typical in residential and light commercial work, and it will not corrode the way a metal cleanout body does in a wet floor. Where the specification calls for a cast iron or nickel bronze top for heavy traffic or a no-plastic requirement, use a metal cleanout instead. The 852 Series is molded ABS with a polypropylene plug.
7) Is the cleanout plug included or do I buy it separately?
Every 852 Series floor cleanout ships with the polypropylene cleanout plug and the lift-out cover. What you still need on the job is the FIP adapter or fitting that the MIP threads screw into, sized to your 3 inch or 4 inch ABS line.
8) I need to standardize floor cleanouts across a multi-family build. Can one part number cover both cover shapes?
No single 852 part covers both shapes. Cover style is designated in the number: 852-3LNR and 852-4LNR are round, 852-3LNQ is square. For a fleet standard, pick one shape and carry the two sizes, 3 inch for branch lines and 4 inch for mains.
