PEX tubing is an economical and cost-effective construction tubing material. Manufacturing PEX tube consumes less energy than manufacturing metallic tube. The lighter weight of PEX helps to lower transportation costs and the wear-and-tear on the installer. The ability to coil PEX decreases the overall footprint of storage and handling thereby saving space. PEX can be installed in ways to reduce the overall fittings used which reduce the possibility of a leak.
1 Tubing Explaining PEX Tubing This section explains PEX Tubing, including manufacturing methods, PEX tube markings, product standards and model codes and material properties. Additionally, some common installations utilizing PEX tubing are listed by installation application. What is PEX Tubing Manufacturing Methods PEX is cross-linked polyethylene. Through one of several processes, links between polyethylene molecules are formed to create bridges (thus the term “cross-linked").
2 PowerPEX Tubing Flexible, Durable, Quality Tubing Made in America This section will explain the types of tubing that Sioux Chief offers, PEX-A and PEX-B. This section introduces compliant tube and fitting systems, tube markings, frequency tests, standards & material benefits. Sioux Chief PowerPEX (Type A) Sioux Chief PowerPEX (Type B) Sioux Chief PEX-A tube can be used with all of Sioux Chief's PowerPEX fitting systems. However, PowerPEX ASTM F1960 fittings can only be used with PEX-A tubing.

PEX Tubing Product Standards & Code Compliance PEX Tubing Product Standards Code Acceptance ASTM F876: Standard Specification for Cross-linked Polyethylene (PEX) Tubing PEX Tubing Code Compliance. Below is a list of commonly referenced and recognized plumbing model codes, which recognize PEX tubing installation and reference standards for application and installation compliance. Individual standards can be referenced in section 6.
Material Benefits & Properties Material Benefits of PEX Tubing Corrosion Resistant. Smooth inner walls, inhibit mineral build up and scaling. PEX is also more resistant to the harmful effects of abrasive chemicals such as chlorine. PEX tube resists pitting or stress-corrosion more than other tubing types. Quiet. Flow characteristics are increased and system noise is decreased when compared to metal tubing systems. Freeze Resistant.

5 General Installation Guidelines Layouts, Examples, Manifold Systems and Common Problems to Avoid This section explains general installation guidelines. It features layouts, examples and manifold systems. This section will explain common problems to avoid, not specific to connection methods. Hybrid Systems/Combination Install Hybrid Systems WHAT: Hybrid systems combine multiple plumbing connection types within one system.
Hybrid Systems/Combination Install Hybrid Systems/Combination Install Continued Combination Systems. Combine the best features of a home run plumbing system with the best features of a trunk and branch plumbing system. Combination: 16 fittings Trunk & Branch: 96 fittings CPVC riser connects directly to manifold This smarter choice: Saves material expense, especially in No Lead compliant systems. Requires half the installation time of traditional systems.
System Installation Options System Installation Options Home Run Fixture outlets are serviced from a central distribution point(s) similar to an electrical panel or breaker box. These manifolds are often referred to as primary manifolds and when used in this manner, can isolate a fixture for repair or service, and can assure proper flow characteristics at the fixture by providing an individual supply line.
Manifold Plumbing Branchmaster Manifold Plumbing Sizing Using manifolds can be accomplished with one of the previously mentioned plumbing layouts. Typically, the size of the manifold is dependent on the amount of fixtures it will be supplying. Sioux Chief offers manifolds with different trunk sizes and in varying outlet connections and sizes. All outside hydrants and/or auxiliary fixtures fed from their own supply line would total the branch quantity needed.
Manifold Plumbing Manifolds with Valve Often located in service rooms or behind access panels Manifolds, Flow-Through Often in-line without valves Radiant Manifolds Allow for fine-tuning of supplied water volume to radiators or tubing loops (not shown in illustration) www.siouxchief.
Tubing Installation Requirements & Limitations Tubing Installation Requirements & Limitations Tube Protection Protect tube with properly regulated and certified stud guards and metal plating where tube protrudes through building members. See tubing insulation requirements below. When undue stress will be placed on a connection joint, use an appropriate fitting with strapping means (drop ear elbow, eared stub out) and make connection to secured fitting. Example: Shower arm installations.
Tubing Installation Requirements & Limitations Horizontal Support Every 32" (556-3 depicted) Vertical Support Every 48" (556-3 depicted) Thermal Expansion Loops/Coils Can be installed for hot tubing Tube Insulators or Acoustical Insulators Protect tube as it goes through the stud (557-3Q depicted) Joint/Valve Support Proper support enables a rigid installation (525-33 depicted) Stud Guard or Metal Plates Protect tube from possible nail penetration (530-3 depicted) www.siouxchief.
Tubing Installation Requirements & Limitations Tubing Installation Requirements & Limitations Continued Sleeving Service Main Where PowerPEX tubing enters foundation walls, rigid tubing shall be used to protect tube from shearing due to ground settlement or other earth movement. The rigid sleeve shall protrude into the earth minimally 12" and pass through to the interior of the building.
Tubing Installation Requirements & Limitations Tubing Installation Requirements & Limitations Continued Water Service Installation & Limitations Getting Started. Local codes should be referenced for acceptable pressures as well as special precautions on use of PEX, system fittings, layout and installation requirements for service piping. Typical water service pressure requirements often mandate that the service is capable of withstanding 1.5x the operating pressure of the system it is supplying.
Tubing Installation Requirements & Limitations Tubing Installation Requirements & Limitations Continued External Temperature Soldering. Soldering shall be performed minimally 18" from installed PowerPEX tubing unless a heat-trapping device is employed. Make all sweat connections and allow cooling prior to making PEX connections to PowerPEX tubing. Duct Work - Heating.
Tubing Installation Requirements & Limitations Tubing Installation Requirements & Limitations Continued Vermin Protection Protect tube from exposure to rodents or other nuisances that may damage the tubing. Water Hammer Exposure Water Hammer is generally defined as the damaging pressure surge and banging noise caused by the quick stoppage of the water column when a valve or faucet is turned off abruptly.
Avoiding Common Problems Avoiding Common Problems Mechanical PowerPEX tubing should not be scratched, gouged or cut along tube length. Handle with care. Metal tubing hangers with sharp edges and corners should be avoided. Metal, vinyl-coated tubing hangers specifically designed for uses with PEX tube are acceptable. A better option would be to use an approved plastic hanger from Sioux Chief's extensive line of CTS hanging options.
Avoiding Common Problems Avoiding Common Problems Continued PPSU (polyphenylsulfone) or Polymer Fitting Limitations PPSU/Polymer fittings shall not be used in applications where temperature and pressure ratings are not regulated or are known to evidence exposures beyond those listed within this manual. See F2159 & F1960 installation instructions and application problems. Sioux Chief PPSU fittings use engineered resin to achieve substantial strength and chemical resistance.
ASTM F878 + F877 PowerPEX or SDR9 Tubing PowerPEX is 3rd party listed and approved and has undergone extensive testing to assure the process, facility, ongoing testing and procedure exceed industry standards for PEX tube extrusion. ASTM tube standards call out the wall thickness, I.D., O.D., % cross-linking, out-of-round, etc. Sioux Chief PowerPEX continuously monitors and checks all of these parameters to assure 100% compliant tube.
