Sioux Chief

Sioux Chief is a manufacturer of rough plumbing products for residential, commercial, industrial, and government construction, founded in August 1957 in Kansas City, Missouri. Operating from a 600,000-square-foot facility that houses manufacturing, distribution, and engineering, Sioux Chief holds more than 30 U.S. patents across its product categories. The company organizes its lineup into four core groups: Supply, Drainage, Support, and Specialties. Supply covers PEX tubing, water heater connections, and valves. Drainage addresses floor drain bodies, residential and commercial drain assemblies, and trench drain systems. Support encompasses pipe bracketing, hangers, and installation hardware. Specialties include water hammer arresters, trap primers, air admittance valves, and outlet boxes. All Sioux Chief products are manufactured in the United States. For contractors working in new construction and remodel, Sioux Chief rough-in products deliver code-compliant solutions with consistent fitment across major pipe types and installation configurations.

Product Lines

Water Hammer Arresters: MiniRester, HydraRester, and MegaRester

Sioux Chief's MiniRester, HydraRester, and MegaRester water hammer arresters protect supply piping from pressure surges generated by fast-closing solenoid valves in appliances such as dishwashers and washing machines. The three lines are sized for different flow rates and installation environments. MiniRester is designed for standard residential 1/2-inch supply lines serving one or two appliances. HydraRester handles larger supply branches or multiple-appliance circuits with greater flow demand. MegaRester addresses high-flow commercial applications on large-diameter mains where surge forces can be significantly higher than residential scenarios.

PowerBar Bracketing System

The PowerBar bracketing system mounts to standard wall framing without additional blocking and secures copper, CPVC, PEX, and steel supply lines as well as drain and vent piping. PowerBar is designed for new construction framing where multiple pipe types run in close proximity, allowing a single bracket solution to reduce material handling. The system prevents settling and vibration-related noise after drywall installation. Contractors specify PowerBar on residential and light-commercial new construction where framed wall cavities need organized, code-compliant pipe support.

OxBox Outlet Boxes

The OxBox system is a line of outlet boxes designed for washing machine, ice maker, and utility supply connections. OxBox boxes mount inside the wall cavity and support supply valves and drain connections at standard rough-in dimensions, providing a finished, accessible bracket that simplifies service access. Sioux Chief offers OxBox configurations for single-valve and dual-valve washing machine hookups, with supply inlet options for PEX, CPVC, and copper. The reinforced construction reduces callbacks related to valve movement or connection stress on flexible supply lines.

TurboVent Air Admittance Valves

TurboVent air admittance valves allow drain-waste-vent systems to operate without extending vent piping through the roof. The valve opens under negative pressure to admit air when drain flow creates a pressure differential, then closes to maintain the trap seal and block sewer gas. Sioux Chief offers TurboVent in sizes for individual fixture venting and branch venting applications. Contractors specify TurboVent on retrofit projects where roof penetrations are restricted and on new construction where routing full vent stacks would require significant structural modification.

FastTrack Trench Drain System

The FastTrack trench drain system is engineered for linear drainage in residential garages, mechanical rooms, shower rooms, and commercial floors. FastTrack uses a modular channel design that simplifies layout and reduces field cutting. The system is compatible with standard 2-inch and 3-inch drain lines. The FinishLine drain series handles individual floor drain installations where a single drain point, rather than a continuous channel, is the appropriate solution.

Why Contractors Specify Sioux Chief

Contractors specify Sioux Chief products for the consistency of sourcing supply, drainage, support, and specialty rough plumbing from a single domestic manufacturer. Sioux Chief holds more than 30 U.S. patents and manufactures from a 600,000-square-foot facility in Kansas City, Missouri. The company produces BABAA-compliant products for federally funded construction projects. The breadth of the Sioux Chief catalog lets a contractor source water hammer protection, drain bodies, pipe bracketing, outlet boxes, and air admittance valves from one company, reducing vendor management on larger jobs. Sioux Chief products are engineered to standard rough-in dimensions and compatible with major plumbing pipe types, supporting consistent fitment across residential new construction, commercial ground-up, and remodel applications.

How to Choose a Sioux Chief Product

The most important decision variable when specifying Sioux Chief products is matching the product line to the installation phase, pipe type, and application environment.

For water hammer protection, start with supply line diameter and the number of solenoid-operated appliances on the circuit. The Sioux Chief MiniRester suits standard residential 1/2-inch supply lines serving one or two appliances. The HydraRester is the right specification when a supply branch serves multiple appliances or carries higher flow rates. The MegaRester handles commercial applications on large-diameter mains. Confirm local code requirements for water hammer arresters before finalizing the specification.

For drainage, match the Sioux Chief product to the flow pattern. The FinishLine series handles single-point floor drain installations. FastTrack trench drain is appropriate where water flows across a broad floor area and a continuous collection channel is needed. FastTrack is available in 2-inch and 3-inch drain line configurations.

For pipe support, PowerBar suits framed wall cavities on new construction where multiple pipe types run in proximity. The system mounts to standard framing lumber without added blocking.

For outlet boxes, Sioux Chief OxBox selection starts with supply line material. Match the OxBox inlet configuration to the pipe type already roughed in. Single-valve boxes suit ice makers. Dual-valve configurations are designed for washing machine installations with separate hot and cold supply inlets.

For any Sioux Chief product requiring code compliance verification, confirm the applicable ASSE or NSF standard before finalizing the specification.

What is the difference between MiniRester and HydraRester water hammer arresters?
The Sioux Chief MiniRester and HydraRester water hammer arresters differ in flow capacity and the supply line configurations each is designed to protect. MiniRester is sized for standard residential 1/2-inch supply lines serving one or two solenoid-operated appliances. HydraRester handles larger supply branches or multiple-appliance connections where higher flow rates generate greater pressure surges. Selecting between the two starts with supply line diameter and the number of fast-closing valves on the circuit.

What size Sioux Chief water hammer arrester is right for a washing machine installation?
For a standard residential washing machine installation on a 1/2-inch supply line, the Sioux Chief MiniRester may be the appropriate arrester size. Washing machines with fast-closing solenoid inlet valves can generate pressure surges that a properly sized arrester is rated to absorb. For installations where the supply branch serves multiple appliances or the supply line is larger than 1/2 inch, the HydraRester may be a more appropriate specification. Confirming supply line size and the number of solenoid valves on the circuit is the starting point for sizing.

Are Sioux Chief OxBox outlet boxes compatible with PEX supply lines?
Sioux Chief OxBox outlet boxes are available in configurations for PEX, CPVC, and copper supply inlets, so compatibility depends on selecting the correct inlet type. OxBox boxes designed for PEX supply accept standard PEX tubing and include the appropriate connection geometry for PEX fittings. Selecting the right OxBox configuration starts with identifying the supply line material and confirming the box inlet matches the pipe type already roughed in.

Which Sioux Chief product handles linear floor drainage in a residential garage?
For linear drainage in a residential garage where water flows toward a single line across the floor, the Sioux Chief FastTrack trench drain system is the appropriate specification. FastTrack uses a modular channel design that collects water along its length and routes it to a standard drain connection. The system is available in configurations compatible with standard 2-inch and 3-inch drain lines. For single-point drainage, the Sioux Chief FinishLine drain series handles individual floor drain applications where a channel is not required.
