Foreword This design assistance manual is published for architects, building officials, engineers and mechanical contractors interested in Uponor professional plumbing systems. It describes general installation recommendations that use Uponor AquaPEX® piping products. Refer to local codes for additional requirements. iv l uponorengineering.com Uponor made reasonable efforts to collect, prepare and provide quality information and material in this manual.
Chapter 1: Uponor PEX properties Uponor PEX properties PEX is an acronym for crosslinked polyethylene. The “PE” refers to the raw material used to make polyethylene; the “X” refers to the crosslinking of the polyethylene across its molecular chains. The molecular chains are linked into a three-dimensional network that makes PEX remarkably durable within a wide range of temperatures and pressures. Currently, three methods exist for producing PEX.
Ultraviolet (UV) resistance The test method for evaluating UV resistance as required by ASTM F876 is ASTM F2657 Test Method for Outdoor Weathering Exposure of Cross-linked Polyethylene (PEX). According to ASTM F876, PEX piping must bear a four-digit code to signify the requirements it meets. The second digit in the code references the minimum ultraviolet (UV) resistance of the piping.
Hydrostatic temperature and pressure ratings Interpolation method Through scientific research and historical experience, hydrostatic design basis (HDB) ratings have been shown to be useful indicators of relative long-term strength of thermoplastic materials when tested under the conditions specified in test method ASTM D2837. The HDB is used to determine the temperature and pressure ratings of a specific material. These temperature and pressure ratings are based on an extrapolated life of 50 years.
Standards, codes and listings Uponor AquaPEX piping is manufactured to meet the following requirements.
ProPEX® fittings Uponor ProPEX® fittings are available in both EP and LF brass and are tested and listed to: • ASTM F1960 Standard Specification for Cold Expansion Fittings with PEX Reinforcing Rings for Use With Cross-linked Polyethylene (PEX) Piping • CAN/CSA B137.
The strength of Uponor EP Uponor EP is made from UDEL® polysulfone, Radel R® polyphenylsulfone or Acudel® modified polyphenylsulfone. These materials are part of a family of polymers that have been used successfully in the demanding environments of medical appliance, aerospace and plumbing for many years. In fact, lab tests prove the Uponor 2" ProPEX EP Tee and ProPEX connection are able to withstand up to 2,900 lbs. of pull force without failure.
Chapter 2: Making ProPEX connections Uponor ProPEX ASTM F1960 (CAN/CSA B137.5) cold-expansion fittings make solid, permanent, manufactured connections without the need for torches, glues, solder, flux or gauges. The unique shape memory of Uponor PEX piping forms a tight seal around the fitting, creating a strong, reliable connection. This document shows how to make proper ProPEX connections using one of the following tools.
Making ProPEX connections with Milwaukee M12 or M18 ProPEX expansion tools Note: All standard Uponor expander heads are compatible with the M12 and M18 tools. Uponor expander heads will not auto-rotate on the Milwaukee tools (only Milwaukee expansion heads will auto-rotate on the M12 and M18). H-heads are not compatible with Milwaukee tools and Milwaukee heads are not compatible with Uponor tools. Milwaukee heads are easily distinguished by color coding and the Milwaukee logo.
6a 6b 6c Shoulder ProPEX coupling Insert ProPEX fitting into ½" Uponor PEX piping. 6d 6e Shoulder Insert ProPEX fitting into 1" Uponor PEX piping. 6. After the final expansion, immediately remove the tool and insert the fitting. Ensure the piping and ring seat against the shoulder of the fitting. Important! Only perform the necessary number of expansions. DO NOT over expand the pipe. You should feel some resistance as the fitting goes into the piping.
Making ProPEX connections with Milwaukee M18 FORCELOGIC ProPEX expansion tools FORCELOGIC expansion head installation The Milwaukee FORCELOGIC ProPEX Expansion Tool for 2", 2½" and 3" Uponor PEX pipe features an auto-rotating head with specially designed alignment cogs. This requires slightly different head installation than the M12 and M18 ProPEX expansion tools for ⅜" to 1½" pipe sizes. 1. Remove the battery pack and place the FORCELOGIC tool in the upright position (cone up). 2.
Making a ProPEX connection 1. S quare cut the PEX piping perpendicular to the length of the piping. Remove all excess material or burs that might affect the fitting connection. 2. Slide the ProPEX ring over the end of the piping until it reaches the stop edge. 3. The Milwaukee tool comes with built-in auto rotation, meaning the head will automatically rotate to ensure the piping is evenly expanded. 1 Note: To cancel the expansion process quickly, pull and release the trigger. 4.
Making ProPEX connections with ProPEX 201 corded expander tools 1. S quare cut the PEX piping perpendicular to the length of the piping. Remove all excess material or burrs that might affect the fitting connection. 2. S lide the ProPEX ring over the end of the piping until it reaches the stop edge. If using a ProPEX ring without a stop edge, extend the ring over the end of the piping no more than 1⁄16" (1mm). 3. Slide the expander head into the piping until it stops.
5. R elease the trigger, remove the head from the piping, rotate it ⅛ turn and slide the head back into the piping. Continue expanding and rotating until the piping and ring are snug against the shoulder on the expander head. See Table 2-2. Important! Rotating the tool between expansions will provide smooth, even expansion of the piping. Failure to rotate the tool will cause deep grooves in the piping which can result in potential leak paths. 6.
Making ⅜" ProPEX connections Proper expander tool and head maintenance When making a ⅜" ProPEX connection, expand the ring once on each side to properly fit over the piping. Refer to the following instructions to make a ⅜" ProPEX connection. • Use a lint-free cloth to apply a light coat of lubricant to the cone prior to making any ProPEX connections. 1. S quare cut the PEX piping perpendicular to the length of the piping. Remove all excess material or burrs that might affect the fitting connection. 2.
Disconnecting a ProPEX brass fitting 2 ProPEX brass and EP fittings are manufactured connections that can be concealed in walls, ceilings and floors. When necessary, ProPEX brass fittings can be disconnected. Important! EP fittings cannot be reclaimed. Refer to the following guidelines for disconnecting a ProPEX brass fitting. 3 1. E nsure the system is not pressurized. 2. U se a utility knife to carefully cut through the ProPEX ring. Important! Do not heat the ring prior to cutting it.
Troubleshooting ProPEX connections Trouble-free ProPEX installations begin with a tool that is maintained in proper working condition. If the tool or segment fingers are damaged, it is very difficult to make a proper connection. Refer to the following guidelines to assist with challenges in the field. Fittings won’t seal • Make sure the expander head is securely tightened onto the tool. • Ensure the segment fingers are not bent.

Underwriters Laboratories (UL) 2846 Until recently, piping materials were to be tested under the ASTM E84 method, which was originally developed to test building construction components. The UL 2846 test method was developed specifically for plastic piping materials to test flame and smoke development. Uponor PEX piping (up to 4") carries the UL 2846 Standard for Fire Test of Plastic Water Distribution Plumbing Pipe for Visible Flame and Smoke Characteristics.
Chapter 4: Pipe sizing s Standard dimension ratio Standard dimension ratio (SDR) is a term used in describing the size of PEX piping — it is the conceptual equivalent of a pipe schedule. Dimension ratio (DR) is the average outside diameter (OD) of PEX piping divided by its minimum wall thickness. Temperature and pressure ratings Temperature and pressure ratings for PEX piping are determined by the Plastics Pipe Institute (PPI) as required by the ASTM F876 standard.

U.S. pipe sizing For sizing an Uponor AquaPEX plumbing system in residential and light commercial buildings in the U.S., use the fixture unit tables for determining pipe size as published in the model plumbing codes. To support this pipe sizing practice, Uponor consulted with the International Code Council (ICC) and the International Association of Plumbing and Mechanical Officials (IAPMO) by means of an evaluation report (ER) to substantiate their approvals.

Friction loss with Uponor PEX piping This method relates friction in piping to the roughness of the pipe, fluid velocity, fluid density (water temperature) and fluid viscosity without leveraging correction factors. This is the same for systems using different concentrations of fluids (e.g., propylene glycol). There are two commonly accepted methods to calculate head loss or friction loss in piping systems.

However, it is not preferred by Uponor (especially for heating and cooling system sizing).
Comparing Darcy-Weisbach and Hazen-Williams NSF performed testing to calculate the friction loss of Uponor PEX pipe and Uponor ProPEX fittings. The testing allowed Uponor to analyze empirical test data and compare it with the Darcy-Weisbach and Hazen-Williams methods. The following graph illustrates the comparison.
The Cv method for calculating friction loss Cv is a function of flow rate versus pressure drop across the fitting. It also accounts for the density of the fluid. Refer to the following friction loss calculation using the Cv method.

Chapter 5: System design and layout This section profiles potablewater design and layout techniques that are primarily found in multi-family and commercial buildings, generally referred to as fire-resistant construction buildings, where both plumbing and building codes apply.
Uponor Logic plumbing Uponor Logic is the smart way to plumb, using flexible Uponor PEX pipe and multiport tees to minimize connections and maximize system performance. With an Uponor Logic layout, plumbing systems typically require fewer fittings than a trunk and branch design and less pipe than a home run layout.

Reverse osmosis and de-ionized water systems 18 percent to 40 percent by utilizing Uponor PEX instead of copper pipe. When comparing the change in sound intensity when switching from copper to PEX piping, with all else remaining the same, the sound intensity in the radial outward direction is the primary area to evaluate.
Hot-water system design Uponor AquaPEX piping is tested and listed to PEX 5106 NSF-pw (CL5). Per ASTM F876, the CL5 chlorine resistance rating is intended for an end-use condition of 100 percent at 140°F/60°C, which is the highest chlorineresistance rating available through ASTM. Products marked with a '5' in the first digit of the four-digit code and also bearing the CL5 designation [e.g.
Heat trace Uponor approves the use of heat-trace cables with Uponor PEX products, provided the product has automatic thermostatic control capability and the temperature does not exceed the maximum rating listed on the piping (200ºF/93.3ºC). Wrap heat tape around the piping and secure the cable with plastic cable ties, not tape; then insulate with either closed-cell or fiberglass pipe insulation Thermal conductivity Uponor PEX pipe has a very low coefficient of thermal conductivity: 0.219 Btu/ (h•ft•ºF).

Uponor Ecoflex® products Ecoflex potable PEX pipes Uponor Ecoflex potable PEX pipe Ecoflex potable PEX pipes feature a single Uponor AquaPEX service pipe for potable-water distribution applications. The piping is surrounded by multi-layer, closed-cell, PEX-foam insulation and a waterresistant, corrugated, HDPE jacket, making it ideal for water service and other direct-burial applications. Ecoflex potable PEX pipes use ProPEX fittings up to 3" or WIPEX™ fittings.
Thermal expansion and contraction All piping systems expand and contract at different rates depending on material characteristics. PEX piping systems exhibit a higher expansion and contraction rate when subjected to changes in temperature as compared to metallic piping systems. Because of its lower modulus of elasticity, PEX is less rigid than metallic piping and develops less force than metallic pipe when exposed to temperature changes.
Ensure the piping layout, including anchors, adequately isolates joints, fittings and connections from high-thrust or bending forces. axial stress in a straight run of piping by transferring it into a moderate bending stress, thereby absorbing the expansion stress. Uponor ProPEX connections have a very high resistance to pull-out forces when compared to other various joint types.
Controlling expansion in cold-water systems Best practice for controlling expansion forces is to continuously restrain the pipe by installing Uponor PEX-a Pipe Support. Domestic cold water systems do not typically experience the temperature differentials seen in domestic hot-water systems, therefore requiring fewer fixed anchor points. Install PEX-a Pipe Support in accordance with the installation guidelines in Chapter 6.
L L ∆L Fixed anchor point L1 Figure 5-9: Expansion loop Figure 5-8: Expansion arm Expansion arm The flexible arm should be long enough to prevent damage, and support clamps should be placed far enough from the wall to allow for longitudinal thermal expansion (see Figure 5-8).
Chapter 6: Installation methods This section profiles potablewater installation methods that are typical for commercial buildings to which both fire and building codes apply (generally referred to as fire-resistant construction buildings). Each method includes a detailed illustration with notes for installing potable-water piping in fire-resistant construction buildings. For specific fire-assembly details, refer to Chapter 3.
Uncoiling PEX An Uponor uncoiler is recommended for convenient uncoiling when the piping is not in the Punch&Pull™ packaging. Bending PEX The minimum bend radius of Uponor AquaPEX pipe is six times the outside diameter of the pipe. Use bend supports for ⅜", ½", ¾" and 1" piping to facilitate 90-degree rigid bends. Use large-diameter PVC conduit to facilitate 90-degree bends in larger-diameter Uponor AquaPEX piping.
Supporting Uponor PEX pipe Suspended runs of Uponor PEX pipe can be supported by the same conventional means as metallic pipe, using copper tube size (CTS) hangers and supports. However, support spacing will vary depending on local code requirements. Note: Uponor recommends using hangers and supports designed for use with plastic piping.
Supporting fittings and valves Sections of pipe with in-line fittings, such as tees, couplings and valves, must be supported per local code requirements. Note: PEX-a Pipe Support cannot be used to increase hanger spacing of these pipe sections.

Uponor PEX-a Pipe Support Insulating PEX-a Pipe Support Tips for cutting PEX-a Pipe Support Hanger and support layouts with PEX-a Pipe Support PEX-a Pipe Support is a 23-gauge galvanized-steel channel for PEX piping with a CTS (copper tube size) controlled outside diameter. It features a profile that is over half-round, making it self-gripping. It provides continuous, uninterrupted support of PEX piping, allowing increased hanger spacing over bare PEX.
General requirements for PEX-a Pipe Support • PEX-a Pipe Support can be used to achieve greater spans than those shown in Dimension A in the table below. • Segments of PEX-a Pipe Support that are greater than the distances in Dimension A in the table below require a minimum of two supports.

Strapping requirements for PEX-a Pipe Support Uponor requires PEX-a Pipe Support be strapped with a minimum 300-lb., tensile-rated, stainless-steel strap that is suitable for the application (i.e., UV, high temperature). Note: Uponor includes required stainless-steel straps with the PEX-a Pipe Support. If the included straps are misplaced, use a stainlesssteel strap of equal or greater strength.
Exposed section must be insulated Expansion and contraction control with PEX-a Pipe Support When properly installed, Uponor PEX-a Pipe Support can reduce linear expansion and contraction by up to 93 percent when compared to bare-PEX pipe. For more information, refer to Table 5-15 on Page 59. Refer to the following requirements.

Support methods The following pages provide examples of PEX installations in various commercial building applications. While not every method is included, the following examples address the majority of installations in North America. Other installation methods are available; contact Uponor for further guidance in these situations.
Steel-frame construction Steel I-beam Approved beam clamp Threaded rod (sized per load requirements) Standard CTS clevis or loop hanger Uponor AquaPEX piping Figure 6-33: Steel beam with standard CTS clevis hangers Steel I-beam Approved beam clamp Threaded rod (size per load requirements) Standard CTS clevis or loop hanger combined with Uponor PEX-a Pipe Support Minimum 300-lb.

Expansion-compensating devices As a generally accepted practice, an expansion-controlling device with fixed anchor points or a continuous run of PEX-a Pipe Support with fixed anchor points is installed every 65 ft. of straight-length piping in a domestic hot-water system. Always install the device at the mid-point of two fixed points (see Figure 6-37).
Uponor AquaPEX pipe risers ½" to 3" Appropriate firestop material (must be Uponor AquaPEX compatible) Use appropriate floor assembly per code Use appropriate wall assembly per code Mid-story guide required between each floor. Maximum spacing is 5 ft. (1.
Public-use fixtures Water hammer is probably the most significant concern when piping for public-use fixtures. In typical installations with metallic piping where back-toback restrooms are separated by a mechanical chase, the supply header is usually kept at roughly the same height as the fixture supply. This creates sharp, abrupt paths for the water, resulting in pressure surges (water hammer) when a fast-actuating valve closes. To compensate, most local codes require water hammer arrestors.
Below-grade and in-slab installation construction. See page 88 for information about termiticides. • Latex caulk Alternative methods to overhead piping include below-grade and in-slab piping. In these installations, the pipe is laid in a trench or secured to steel-reinforcing bar (rebar) or wire mesh and routed to the desired locations. The piping system is pressurized (usually 20 psi above working pressure) and buried.

Trench bottom preparation To achieve a satisfactory installation, it is essential that the soil provides stable and continuous support for the piping. Uponor PEX piping Uponor PEX piping Undisturbed soil Undisturbed soil Fill level Excavation level Excavation level Figure 6-46: Good soil conditions — If the trench is dug smoothly, install the piping directly on the prepared bottom. The bottom must be flat with no hollows, lumps or rocks.
H-20 loads When installing Uponor AquaPEX under a roadway, follow the same procedures as previously indicated with the following exception: Ensure the top of the piping is 16" below the bottom of the roadbed material as specified. You can also use a suitable steel or structural conduit to sleeve the Uponor AquaPEX pipe. Pedestrians Bicycles H-20 load Deepest point of road bed 0 2083 pounds p.s.f. 10" native soil 6" sand (min.
Water system disinfection Uponor recommends flushing an AquaPEX plumbing system with clean, potable water. When system disinfection is required, disinfect the piping in accordance with AWWA C65186, Standard for Disinfecting Water Mains, or local codes. Important: To prevent reduced service life of system components, do not allow disinfection solutions to remain in the system longer than 24 hours. Flush the system with potable water after disinfection.
Insulation Some local codes require insulation on cold-water lines to mitigate condensation that can occur on the outside of the piping. This is more specific to metallic piping. The thicker, more insulating walls of PEX piping give it a very low coefficient of thermal conductivity (0.219), whereas copper has a coefficient of thermal conductivity around 173-231. In short, PEX piping does not sweat like copper piping.
Painting Uponor AquaPEX It is acceptable to use latex and acrylic-based paint, such as 100 percent acrylic exterior latex house paint, with Uponor AquaPEX. These products will not harm the molecular structure or integrity of the PEX piping. Termiticides/pesticides Liquid termiticides/pesticides are often applied to treat the soil below the concrete slabs of slab-on-grade structures. The treatment creates a barrier to prevent termites and pests from infiltrating the floor of the structure.
