Section 1
The Uponor Plumbing System
The Uponor Plumbing System consists of the following
Uponor PEX tubing and Uponor plumbing components:
•Uponor AquaPEX® Red, White and Blue tubing
•AquaPEX Reclaimed Water (purple) tubing
•Pre-insulated Uponor AquaPEX tubing
•Pre-sleeved Uponor AquaPEX tubing
•ProPEX® Engineered Plastic (EP) Fittings
•ProPEX Brass Fittings

PEX is an acronym for crosslinked polyethylene.
The PE refers to the raw material used to make PEX
(polyethylene), and the X refers to crosslinking 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.
Uponor manufactures PEX tubing using the Engel
method, a hot-crosslinking process. The actual
crosslinking takes place during the extrusion process
when the base polyethylene is above its crystal-melting
temperatures. Classified within the industry as PEX-a
tubing, Engel-method PEX is superior to other types
of PEX — resulting in consistent, uniform and evenly
crosslinked PEX. Uponor AquaPEX also demonstrates
a great resistance to chemical-dissolving agents. This
unique structure is stable and inert, and it is unaffected
by chemicals commonly found in plumbing and heating
systems. Uponor AquaPEX tubing is reliable, used in
plumbing systems around the world for more than
30 years — longer than any other flexible plumbing
system on the market.

Fire-resistant Standards
For a complete list of the fire-resistant standards, codes
and listings, refer to the Uponor Plumbing Design
Assistance Manual (PDAM).
Firestop Listings
Numerous firestop manufacturers have tested their
products with PEX tubing. These tests establish the
installation procedures for installing the firestop around
PEX tubing at the penetration. The type of penetration
(e.g., wall, floor or ceiling) determines how these test
assembly sections are divided.
Not all caulks are approved for all penetrations. Make
sure you seal the penetration in accordance with the
appropriate test assembly, using the type of firestop
material recommended by the manufacturer. Larger
penetrations may not allow the use of some caulk type
of firestop — a wrap or collar assembly may be required.
Refer to the respective firestop manufacturer for more
information on appropriate applications of their products.
Current firestop products that are compatible with
Uponor AquaPEX tubing include:
•RectorSeal Metacaulk Intumescent Firestop
•Nuco Selfseal GG-266 Firestop
•3M Fire Barrier IC 15WB+ Sealant
•Hilti FS-1 Fire Caulking
These products, based on their chemical composition,
were tested and found to be compatible with Uponor
AquaPEX tubing. There are numerous other firestop
products available on the market that may be compatible
with Uponor AquaPEX, though some have not gone
through the Uponor verification process. If there are
other firestop products you would like reviewed for
compatibility, please contact Uponor at 800.321.4739.
Applications
Recirculation Systems
Based on our extensive history of use and testing,
Uponor provides the following guidelines for using
Uponor PEX tubing and corresponding fitting systems
in recirculating systems.
Note: Uponor does not promote the use of continuous
recirculation due to excessive energy waste.
•The tubing is marked with the following designation
as required by the most recent edition of ASTM
F876: PEX 5006. The first digit indicates chlorineresistance testing (“5” means compliance with ASTM
F876, Chlorine-resistance Testing for Continuous
Recirculating Systems).
•Do not exceed the published temperature and pressure
ratings of the tubing.
•Using recirculation systems may increase the risk
of scalding. Therefore, Uponor recommends limiting
the delivered water temperature to 120ºF (49ºC) in
all cases.
Uponor Residential Fire Safety Systems
The Uponor Residential Fire Safety system is a residential
fire protection system installed in combination with the
cold side of the domestic potable water system. Only
licensed contractors trained by Uponor can install this
system. Contact your local Uponor representative for
more information about training certification and project
support for the Uponor Residential Fire Safety system.
Combined Potable-water and
Hydronic-heating Systems
Uponor AquaPEX can be used in combined potable
water and hydronic heating systems where allowed
by code. Depending on the heating-control strategy
employed, these systems typically do not exceed 140ºF
(60°C). If the system water temperature will exceed
140ºF (60°C), the installing contractor is responsible for
providing anti-scald devices to protect the inhabitants.
In addition, the installer must ensure, and is responsible
for, providing weekly off-season (summer) circulation
through the heating portion of the system to prevent
water stagnation.
Contact your local plumbing and heating code official to
see if code allows these combined systems in your area.
If allowed within your area, be sure to complete a proper
heat-loss and design plan that takes into account the loss
of heat energy between the two systems. It is advisable
to have a clear knowledge of the resulting impact on the
performance of each of these systems prior to installation.
•Uponor AquaPEX is suitable for use in:
o Recirculation systems operating up to 140ºF (60ºC)
o Timed, sensor-activated or self-activated recirculation
systems operating at temperatures not exceeding
140ºF (60ºC)
o Continuous recirculation systems operating at
temperatures not exceeding 140ºF (60ºC)

Section 2:
Working with Uponor PEX Tubing
General Storing and
Handling of PEX Tubing
• Do not store PEX tubing outdoors.
• Keep PEX tubing in the original packaging until you
are ready to install.
• Ensure that exposure to sunlight during installation
does not exceed the maximum recommended UV
exposure time of 30 days.
Uncoiling PEX Tubing
We recommend using one of the following Uponor
uncoilers to facilitate convenient uncoiling of PEX tubing:
•Uponor Select Uncoiler (E6062000)
•Uponor Compact Select Uncoiler (E6063000)
•Uponor Tube Uncoiler (E6061000)
If one is not available, construct a suitable uncoiler.
4.Let the repaired Uponor AquaPEX tubing cool
undisturbed to room temperature. When the
tubing returns to its opaque appearance, the
repair is complete.
Uponor AquaPEX tubing repaired according to these
recommendations will return to its original shape and
strength. If Uponor AquaPEX tubing is sliced, punctured
or otherwise damaged beyond the capacity of the
crosslinked memory, it is necessary to install a coupling.
Crosslinked polyethylene cannot be welded or repaired
with adhesives.
Note: You may temporarily affix adhesive tape to PEX
tubing or EP fittings during installation. However, to
protect the integrity of the system, the tape should not
be permanent. Remove the tape and residual adhesive
after completing the installation.
Thawing Frozen Tubing
Bend supports are available for 3⁄8", 1⁄2", 3⁄4" and 1"
Uponor AquaPEX tubing to facilitate 90-degree
rigid bends.
Uponor AquaPEX tubing exceeds other tubing and piping
in its ability to withstand extreme freeze/thaw cycles.
The crosslinked structure of the tubing allows it to
expand and absorb much of the expansion energy from
the freezing process. No tubing product is freeze-proof,
but Uponor AquaPEX tubing is extremely resistant to
freeze damage.
Reforming Kinked
Uponor AquaPEX Tubing
If freezing occurs, the contractor should advise the
end-user to correct the lack of insulation or heat to
eliminate the possibility of future problems.
Bending PEX Tubing
The minimum bend radius of Uponor AquaPEX tubing in
any direction is six times the outside diameter (6 x OD).
For kinked tubing that hinders flow, repair as follows:
1.Ensure that the system is not pressurized.
If the tubing experiences an ice blockage, thaw the
tubing as follows:
2.Straighten the kinked portion of the tubing.
1.Pour hot water over the affected tubing area.
3.Heat the kinked area to approximately 265°F
(129.4°C) with an electric heat gun (approximately
450 watts of power). Apply the heat evenly until
the tubing returns to its original size and shape.
Do not use an open flame.
2.Wrap hot towels around the affected tubing area.
aution: Do not allow the temperature of
C
the tubing surface to exceed 338°F (170°C).
Do not apply direct flame to Uponor
AquaPEX tubing.
Professional Plumbing Installation Guide
3.Place a small, portable heating device in the area
to heat the space and thaw the ice blockage from
the tubing.
4.Slowly heat the affected area of the tubing with a heat
gun. Rub your hand over the area while heating the
tubing to ensure the tubing does not get too hot.
5.Use a commercial system that pumps hot water to
the ice blockage and returns the cooled water to be
re-heated.

Using the ProPEX Hand Expander Tool
Prior to use, ensure that you perform proper lubrication
of the ProPEX Hand Expander Tool (Q6275075) — refer
to Making ProPEX Connections in this section. When
using the expander tool, brace the free handle of the
tool against your hip or place one hand on each handle.
Fully separate the handles and slide the expander head
into the tubing until it stops. For proper connections, it is
critical to make full expansions.
Once expanded, separate the handles and remove the
head from the tubing. If you are not using the ProPEX
Auto Rotation Adapter (Q6323810), then you must
manually rotate it one-eighth (1⁄8) turn in either direction.
The Auto Rotation Adapter will automatically rotate the
expander head after each expansion. Slide the tool head
into the tubing in the newly rotated position and expand
again, as required.
ProPEX Rings with Integral Stops
A ProPEX Ring is required to make a ProPEX connection.
The ProPEX 1⁄2" and 3⁄4" rings now include a leading edge
chamfer and integral stop edge to simplify the use of
ProPEX fittings.
The Importance of Correct Expansion
It is important to make strong, reliable connections.
Correct expansion procedures are critical in preventing
leaks. Make connections by sliding a ProPEX Ring over
the PEX tubing and expanding them simultaneously. The
expanded tubing and ProPEX Ring then slide over the
fitting. The connection occurs as the PEX tubing shrinks
over the fitting because of the unique shape memory of
Uponor AquaPEX. Please read the following directions
completely before you begin.

Making ProPEX Connections
The following steps illustrate how to make proper
connections using a ProPEX expander tool.
1.Lightly grease the cone of the ProPEX Expander
Tool (manual, air, corded or battery).
2.If using an auto rotation adapter, snugly thread the
ProPEX Auto Rotation Adapter (Q6323810) onto
the tool. Remove excess oil from the adapter cone,
and then lightly grease the cone of the adapter.
Figure 3-1: ProPEX Expander Tool
Caution: Lack of grease may cause the
expander to lock in the open position. If the
expander locks open, unscrew the head and
apply grease to the adapter cone.
3.Select the proper expander head (see Table 3-2 on
page 10 for reference).
Note: H-heads are not compatible with the ProPEX
Hand Expander (Q6275075) or the ProPEX Auto
Rotation Adapter (Q6323810).
Figure 3-2: ProPEX Expander Tool Preparation
4.Thread the proper expander head onto the ProPEX
Expander Tool or the ProPEX Auto Rotation Adapter.1

N
ote: When using the ProPEX Auto Rotation Adapter
(Q6323810), open and close the expander tool a few
times to engage the auto-rotation feature prior to
tube expansion (see Figure 3-3).
5.Square-cut the PEX tubing perpendicular to the
length of the tubing (see Figure 3-4).
Figure 3-4: Square-cut the PEX Tubing
6.Slide the ProPEX Ring over the end of the tubing as
shown in Figure 3-5. Extend the end of the ring over
the end of the tubing no more than 1⁄16" (1.6mm).
When using a ProPEX Ring with a stop edge, slide the
ring onto the tubing end until it hits the stop.
7.Gently slide the expander head into the tubing until
it stops (see Figure 3-6).
Important: Do not force the expander head into
the tubing.
8.Close the handles of the manual tool or press the
trigger of the power tool to expand. Open the handle
(manual tool) or release the trigger (power tool) and
remove the expander tool from the tubing, then
rotate the expander head one-eighth (1⁄8) of a turn.
(Note: The Auto Rotation Adapter rotates the
expander head automatically.) Reinsert the tool
into the tubing for the next expansion. Refer to
Table 3-2 for the recommended number of
expansions required for your tubing size.
Professional Plumbing Installation Guide

I mportant: Rotation of the expander head in either
direction after EVERY expansion is necessary to provide
smooth and even expansion of the tubing. If using the
Auto Rotation Adapter, manual rotation of the expander
head is not necessary. See Figure 3-7 for a view of
tubing when proper rotation is accomplished.
Note: When not using the Auto Rotation Adapter, it is
not necessary to rotate the tool in only one direction.
Alternating the turning direction will ease expansion in
confined spaces.
Figure 3-7: Expansion with Proper Rotation
If you fail to reposition the head after each expansion,
the segments of the tool head may cause deep grooves
in the tubing, which could result in potential leak paths.
See Figure 3-8 for a view of tubing resulting from
improper rotation.
Figure 3-8: Expansion without Proper Rotation
Table 3-2 provides the recommended range of
expansions needed for various tubing sizes depending on
the expander tool used (manual, air, corded or battery).

Important Tips for a Proper
ProPEX Connection
•If the fitting does not slide into the tubing all the way
to the stop, immediately remove it from the tubing and
expand the tubing one final time.
Note: To avoid overly expanding the tubing, do not
hold the tubing in the expanded position.
•Table 3-2 indicates the recommended number of
expansions for each tubing size. Experience, technique
and weather conditions influence the actual number of
expansions. Fewer expansions may be necessary under
certain conditions. The correct number of expansions
is the number necessary for the tubing and the ring to
reach the shoulder of the expander head before the
final expansion.
•Good connections result when the ProPEX Ring rests
snugly against the stop of the ProPEX fitting shoulder.
If there is more than 1⁄16" (1.6mm) between the ring
and the shoulder of the fitting, square-cut the tubing
2" away from the fitting, and make a connection using
a new ProPEX Ring.
Making 3⁄8" ProPEX Connections
The 3⁄8" ProPEX Ring is smaller and thicker than the
rings used for other tubing sizes. To fit over the tubing
properly, the 3⁄8" ProPEX Ring must be expanded once
on each side. Expansion of the ProPEX Ring is only
necessary for 3⁄8" Uponor AquaPEX.
1.Square-cut the 3⁄8" Uponor AquaPEX tubing
perpendicular to the length of the tubing.
2.Expand each side of the 3⁄8" ProPEX Ring with the
ProPEX Expander Tool once.
3.Slide the expanded 3⁄8" ProPEX Ring over the end of
the tubing. Make sure the end of the ring extends over
the end of the tubing no more than 1⁄16" (1.6mm).
4.When the 3⁄8" ProPEX Ring is properly expanded,
gently slide the expander head onto the tubing until it
stops (do not force).
5.Close the handles of the manual tool or press the
trigger of the power tool to expand. Open the handle
(manual tool) or release the trigger (power tool) and
remove the expander tool from the tubing. Then
rotate the expander head one-eighth (1⁄8) of a turn
(Note: The Auto Rotation Adapter rotates the
expander head automatically). Reinsert the tool into
the tubing for the next expansion. Refer to Table 3-2
on page 10 for the recommended number of
expansions required.
Note: If not using the Auto Rotation Adapter, rotate
the expander head in either direction after EVERY
expansion. This will ensure a smooth and even
Professional Plumbing Installation Guide
expansion of the tubing. It is not necessary to rotate
the tool in only one direction. Alternating the turning
direction will ease expansion in confined spaces. It is
important to reposition the head after each expansion.
Expansion is complete when the tubing and ring are
snug against the shoulder on the expander head.
6.Immediately remove the ProPEX expander tool. You
should feel resistance as you insert the fitting. The
tubing and ProPEX Ring should be set against the
shoulder of the fitting for a proper connection.
Important Tips for a Proper 3⁄8"
ProPEX Connection
•When the temperature is above 40°F (4°C), ProPEX
connections to 3⁄8" Uponor AquaPEX tubing require
four to five expansions. When the temperature is
below 40°F (4°C), only four expansions are necessary.
•The thicker
⁄8" ProPEX Ring shrinks over the fitting
faster than other sizes of rings.
3
Disconnecting a ProPEX
Brass Fitting
ProPEX brass fittings are manufactured connections that
the installer can conceal in walls, ceilings and floors.
However, when necessary, the installer can disconnect
ProPEX brass fittings. To disconnect a ProPEX brass
fitting, use the following steps.
1.Turn off the supply valve and open faucets to drain the
system and ensure that the system is not pressurized.
2.Use a heat gun to heat one side of the ProPEX Ring.
When the ring is clear, use a utility knife and carefully
cut through the ring parallel to the tubing to avoid
cutting into the sealing barb of the fitting. Remove
the ProPEX Ring from the tubing with pliers to avoid
touching the hot ring.
Note: Do not gouge the fitting when cutting the
ProPEX Ring. Nicks and gouges in the fitting could
result in leaks. If gouged, discard the fitting.
3.When removing the ProPEX Ring, apply heat directly
around the fitting and tubing connection. Gently
work the tubing back and forth while pulling slightly
away from the fitting until the tubing separates from
the fitting.
4.After removing the tubing from the fitting,
square-cut the tubing a minimum of 2" from the
end of the tubing.
5.Use a new ProPEX Ring and follow the steps to make
a new ProPEX connection. Allow the fitting to cool
before attempting to make another connection.
Note: EP fittings cannot be reclaimed or reused.

Troubleshooting
ProPEX Connections
Smooth ProPEX installations begin with a well-maintained
ProPEX expander tool. If the tool has damaged conical
or segment fingers, it is very difficult to make a proper
connection. The following suggestions assist with
troubleshooting in the field.
For Fittings That Will Not Seal
•Make sure that you have securely screwed the
expander head onto the tool (hand-tightened).
•Examine the tool to ensure there are no bends in the
segment fingers of the expander head. If the head
does not completely close when the internal cone of
the expander tool is fully retracted, replace the head.
•Examine the tool for excess grease on the
internal cone or segment fingers of the expander
head. Remove excess grease prior to making
ProPEX connections.
•Examine the fitting for any damage. Sharp nicks and
gouges on the fitting will cause the fitting to leak.
•Ensure the internal cone is not damaged or bent.
•Make sure the last expansion is not held in the
expanded position before the fitting is inserted.
The longer the tubing and ProPEX Ring are held in
the expanded position, the greater the chance for a
leak (due to over-expansion).
•If you are not using the ProPEX Auto Rotation
Adapter, be sure to rotate the tool one-eighth (1⁄8)
turn in either direction after each expansion.
If Expansion is Difficult
•Make sure the internal cone is properly greased.
If the Expansion Head Slips Out of the
Tubing When Making Expansions
•Ensure the tubing and ProPEX Ring are dry.
•Make sure that grease is not getting into the tubing.
•Examine the segment fingers of the expander head to
make sure there are no bends.
If the ProPEX Ring Slides Down the
Tubing During Expansion
slightly more than 1⁄16" (1.6mm) over the end of the
tubing and make the first few expansions slowly.
Once the ring and the tubing begin to expand
together, you can continue with the normal number
and type of expansions.
•Place your thumb against the ProPEX Ring for support
and feel for any movement. If caught early, you can
slide the ring up the tubing and expand as described in
the previous bullet point.
If More Than the Recommended
Number of Expansions are Needed to
Make a Connection
•Make sure that the head is hand-tightened to the
expander tool.
•Examine the expander head to make sure that no
segment fingers are bent.
•Be sure to completely cycle the tool on each
expansion, (e.g., close the manual tool handle or
release the trigger of the battery expander tool).
Cold-weather Expansions
•Temperature affects the time required for the tubing
and ring to shrink onto the fitting. The colder the
temperature, the slower will be the contraction time.
•Warming ProPEX fittings and ProPEX rings reduces
contraction time. Put fittings and rings in your pockets
or keep them in a warmed box prior to installation to
keep them warm.
•ProPEX connections must be made at temperatures
above 5°F (-15°C).
•Fewer expansions are necessary in temperatures below
40ºF (4°C).
Proper Expander Tool and
Head Maintenance
•ProPEX expander tools are sturdy, but you must handle
with care to prevent possible damage to the cone and
the expander heads.
•Remove and clean the segment fingers as needed.
•Remove the segments from the attachment ring by
pushing the segment finger down toward the opening
in the ring. Once you have removed the first segment,
the rest follow easily.
•Ensure your hands are clean while handling the tubing. •Place the segments on a flat surface with the ridges
Any sweat or oils on your hands can act as a lubricant.
Due to the smoothness of PEX, any form of lubricant
can cause the PEX Ring to slide across the tubing
during expansion.
facing up. The fingers should lay flat without any curve
in the middle. If the segments are bent, replace the
head immediately.
•If you anticipate any sliding, position the ProPEX Ring

Section 4:
Water Service Phase
To reform kinked tubing, refer to Section 2: Reforming
Kinked Uponor AquaPEX Tubing on page 5. If
damaged beyond the thermal memory capacity of the
tubing, use a ProPEX repair coupling that is suitable for
direct burial.
Uponor AquaPEX tubing meets the requirements of the
following standard:
•ANSI/AWWA Standard C904-06, Crosslinked
Polyethylene (PEX) 1⁄2 inch (12mm) through 3 inches
(76mm) for Water Service
Please refer to the ANSI/AWWA Standard for information
regarding the selection, use and proper application of
PEX tubing in water service.
Note: Do not reuse or reclaim EP fittings.
Trench Bottom Preparation
For a successful installation, the supporting soil must
provide a stable and continuous support for the tubing.
Handling and Repairs
Although Uponor AquaPEX tubing is highly resistant
to kinking and abrasion, it is important to handle with
care while installing the tubing to prevent damage and
possible failure. If damage occurs during installation, cut
out and repair the area before backfilling.
Minimum 24" for
Vehicular Traffic
Good Soil Conditions
If the trench cut is relatively smooth, install the tubing
directly on the prepared bottom. The bottom must be flat
with no hollows, lumps or rocks.

Joining Methods and Fittings
If installing in rocky, clay, muddy or other poor soil
conditions, it may be necessary to prepare the trench
bottom using granular material of such size and grading
to provide a stable base. See your local code for
additional requirements.
Use ProPEX or approved compression fittings to connect
tubing to itself or to the corporation and curb stops.
Check with Uponor or the fitting manufacturer for
application suitability and proper usage instructions.
Common fittings for direct burial include:
Installation
Install Uponor AquaPEX tubing underground in a
manner that avoids damage caused by external loads.
External loads should not cause a decrease in the
vertical dimension of the tubing cross-section more
than 5% of the outside diameter. To ensure proper
underground installation:
•Install Uponor AquaPEX tubing in a snaking
pattern with sufficient slack in the line to allow for
contraction of the line due to temperature change
prior to backfilling.
•The linear expansion rate for Uponor AquaPEX tubing
is approximately 1.1" per 10°F (5.6°C) temperature
change for every 100' of tubing.
•Do not use blocking to support the tubing or change
the tubing grade.
•Do not install potable water service tubing in, under
or above cesspools, septic tanks, septic tank drainage
fields or pits.
16
•Dezincification-resistant (DZR) Brass Fittings
•Red Brass Fittings
•Lead-free Brass Fittings
•EP Fittings
•Stainless Steel
You can identify the fitting type by the print stream on
the fitting (e.g., c314 = Red Brass).
ProPEX Red Brass Adapters are a brass transition-fitting
solution that is resistant to both dezincification and stress
corrosion cracking due to its lower zinc content.
Note: Water service fittings designed for SDR-9 tubing
available from other manufacturers (FordPack, AY
McDonald and WIPEXTM) are approved for use with
Uponor AquaPEX tubing in cold-water service
applications. A pipe stiffener for the appropriate
size of PEX tubing is required for use with these
fittings. Please contact the fitting manufacturer for
temperature and pressure ratings.
www.uponor-usa.com • www.uponor.ca
Tubing Embedment
Proper soil selection, placement and compaction are
essential in the area around the tubing. Use sand or
gravel with a maximum particle size of 3⁄4" to backfill
the tubing.
Compact the initial backfill around the tubing to
provide adequate tubing support and prevent
settlement. It is particularly important to compact the
soil adequately around the tap connection. Uponor
recommends that you pressurize the tubing prior to
backfilling to reveal any damage. In heavy traffic areas,
compact the backfill to 90% of maximum soil density.
Do not use highly plastic clays, silts, sharp or large
rocks and organic materials as backfill in the immediate
vicinity of the tubing. Compact the backfill from the
sub-grade to a level compliant with local code that will
cover the tubing 4" to 6". This will provide protection
around the tubing and prevent settlement that puts
stress on the fittings and the tubing.
For additional information about proper embedment
practices, refer to ASTM D2774, Standard
Recommended Practice for Underground Installation of
Thermoplastic Pressure Piping, or AWWA Report TR31,
Underground Installation of Polyolefin Piping.
Water System Disinfection
Disinfect Uponor AquaPEX tubing in accordance with
AWWA C651, Standard for Disinfecting Water Mains,
or in accordance with local codes.

Section 5:
Ground and Top-out Stage of Installation
After installing the service water line into the building,
the next area of focus is the groundwork —under
and in the soon-to-be-poured concrete. The level of
activity during the groundwork stage varies throughout
the country. Areas doing primarily slab-on-grade
construction may put the bulk of the tubing in the slab,
below the slab or run it overhead in the attic. Traditional
homes with basements will run the majority of tubing
within the building framework.
Parts Inspection
To eliminate work delays, make sure all required
material is at the job site prior to beginning a project.
Use contractors trained to evaluate component
suitability for installation. Check for material defects,
incomplete parts or shipping damage. Check to see
that the correct amount and type of PEX tubing is on
site to start the project.
Sleeve Protection
Figure 5-1: Sleeve Protection
Installing Uponor AquaPEX
Tubing During Ground Work
•Properly secure tubing at intervals necessary to keep
the tubing from floating up during the pour.
•When installing fittings for in-slab applications,
use only EP fittings. For under-slab applications,
use EP, Red Brass, Lead Free or DZR Brass
ProPEX fittings.
•When passing through a concrete slab, ensure tubing
is protected and allows for movement, including
expansion and contraction of tubing. Minimum wall
thickness of protective material shall be 0.025"
(0.64mm). Approved protective material includes
HDPE wrapping, closed-cell pipe insulation, PVC
elbows and sleeves or equivalent. Ensure proper
tubing placement when exiting the slab.
Dip Below Joint
Figure 5-2: Dip Below Joint
Caution: Uponor recommends using a ProPEX
EP coupling to repair tubing damaged during a
concrete pour. If a ProPEX EP coupling is not
available, you can use a ProPEX brass coupling
wrapped with a protective polyethylene sleeve
to prevent direct contact between the concrete
and the brass coupling.
•Maintain pressure on tubing installed in a slab during
the pour to facilitate leak detection.
•If the tubing will be exposed to sunlight for
more than 30 days, sleeve the tubing to protect
against damage.
•If the tubing runs through an expansion joint,
protect with a sleeve or dip below the joint.
See Figures 5-1 and 5-2.

Termiticide or Pesticide Treatment
Uponor PEX tubing for hot- and cold-water distribution
(plumbing) is approved for installation directly within or
below concrete slabs where soil termiticide or pesticide
treatment is required. This is especially useful in slabon-grade construction. You are not required to sleeve
PEX tubing installed within or below concrete slabs.
We recommend using either flexible polyethylene (PE)
protection sleeve or rigid polyvinyl chloride (PVC) bend
guides at all slab penetrations to protect PEX tubing
from abrasion where they pass through the concrete slab.
These products are slab-penetration protection devices
that you can use to fortify and protect the tubing.
When using Pre-sleeved Uponor AquaPEX tubing or
a protection sleeve, an annular gap between these
protection devices and the PEX tubing will exist. In such
installations, you will need to fill the annular gap between
the protection device and the PEX tubing at the exposed
ends. This will help prevent pathways for pests or
accidental application of harmful chemicals into the space
between the PEX tubing and the protection device. Use
only sealants that are compatible with PEX tubing.
application of harmful chemicals into the space
between the PEX tubing and the protection device.
Use only sealants that are compatible with PEX tubing.
4.When PEX tubing is continuously sleeved below or
above a slab (e.g., when using 1⁄2" Pre-sleeved
Uponor AquaPEX tubing), the space between the
tubing and the sleeving must never be filled with any
liquid chemical, including pesticides or termiticides.
Prevent pooling or puddling of these liquids around
PEX tubing.
5.When it is necessary to retreat soil near PEX
tubing, prevent the puddling or pooling of the
termiticide or pesticide.

• Latex Caulk
• Latex Foam
• Silicone Sealant
• Polyurethane Expanding Foam

1.If termiticides or pesticides are applied while the
installed PEX tubing has exposed open ends not yet
connected to plumbing fixtures, the ends of the tubing
must be capped, plugged or closed to prevent these
chemicals from entering the tubing.
2.Do not allow organic (petroleum-based) chemicals,
petroleum distillates, termiticides or pesticides to come
into direct contact with PEX tubing.

•Insulate hot- and cold- water tubing runs where code
requires or as necessary.
•For information about locations and techniques for
drilling though load-bearing construction, consult your
local building codes.
•In residential or non-return plenum applications, you
may bundle cold water tubing runs together and/or
hot water tubing runs together with a suitable plastic
material, unless prohibited by local code. Best practices
do not recommend the bundling of hot-water tubing
runs and cold-water tubing runs together.
Caution: When installing in attics, install
the tubing below the insulation. Note the
location of fittings in the attic space for
inspection purposes during pressure testing.
Recessed Lighting
When installing Uponor AquaPEX tubing near recessed
light fixtures, we recommend that the tubing be a
minimum of 12" away from the light fixture. When it is
necessary to install closer than 12" away from a light
fixture, follow these guidelines:
•If there is not enough room in the joist cavity to meet
the 12" restriction stated by Uponor, then insulation
around the tubing is required.
•Use only insulation rated to withstand the temperature
generated by the fixture.
www.uponor-usa.com • www.uponor.ca
•Insulate all tubing that is within 12" of the recessed
light with closed-cell polyethylene, polyolefin or other
suitable pipe insulation for a distance of 12" on either
side of the light fixture.
•Insulation is required anytime a UV light source is used
(including fluorescent bulbs); you must protect tubing
from direct and indirect UV exposure.
Tubing Supports: Horizontal Runs
•Along horizontal runs, install supports every 32".
If horizontal runs are continuously supported
(truss-to-truss), install a tube talon every second
or third truss. Follow local code requirements when
installing PEX tubing in fire-resistive construction
floors, ceilings, or walls.
N
ote: There are two types of recessed lights: Type I.C.
(Insulated Ceiling), which allows direct contact with
thermal insulation, and Type Non-I.C. (Non-insulated
Ceiling), that requires a 3" minimal clearance from
thermal insulation.
Tubing Supports: General Guidelines
•Uponor recommends using plastic or metal tubing
supports designed for use with plastic tubing.
•Do not use supports that will damage the tubing.
Inspect metal supports for sharp edges.
•Allow for the linear expansion rate of Uponor AquaPEX
tubing — approximately 1.1" (27.9mm) per 10°F
(5.6°C) temperature change for every 100’ of tubing.
o When installing tubing runs, thermal expansion
calls for an extra 1⁄8" to 3⁄16" of longitudinal
clearance per foot of run. Do not allow tubing
to dip excessively between supports. Do not pull
tubing tight during installation.
o Do not rigidly anchor Uponor AquaPEX tubing with
supports to allow tubing to expand and contract.
Figure 5-3: Tube Talons for
Horizontal Runs
Tubing Supports: Vertical Runs
•Along vertical runs, install supports at the base of each
floor and mid-story guide.
•Allow adequate clearance between PEX tubing and the
structure (bored holes or sleeves) to allow tubing to
move freely due to thermal expansion and contraction.

Pressure Test the System
•You must pressure test the system in accordance with
local code requirements, but the recommended test
pressure is at least 25 psi above working pressure or
100 psi. Slight fluctuations of pressure are normal
due to ambient temperature changes.
•When testing with air, let the system pressure
stabilize before starting the test.
•Test pressures above 160 psi will cause a slight radial
expansion of the tubing and a subsequent relaxation
of the material, resulting in a reduction of test pressure.
This is normal and does not indicate a leak.
•When using valved manifolds, open the valves on the
manifold prior to pressure testing. Ensure the valves
remain open until the pressure test is complete.
Back-draining the System
•If you anticipate that the structure will be unoccupied
during cold climate, allow a drain for the system
and blow out any remaining water with air.
Hose Bibs
•Connect Uponor AquaPEX tubing to a standard

Pressure Testing
•During the rough-in stage, open all valves prior to
pressure testing. These valves are to remain open
until the pressure test is complete.
•You must pressure test the system to the system
working pressure (40 to 60 psi) with air or water.
Consult the local code and pressure test at the current
ambient temperature. Slight fluctuations of pressure
are normal due to ambient temperature changes.
Caution: If using water to pressure test the
system, purge all water from the system prior
to ambient air temperatures nearing 32ºF
(0ºC). Failing to remove the water from the
system can result in damage to the tubing
and associated equipment.
