PEX Handling Guidelines for use in
Hot- and Cold-water Distribution Systems
The following highlights the most common guidelines for installing Uponor PEX tubing
in water distribution systems. For applications other than water distribution systems,
refer to the appropriate Uponor manuals or contact your Uponor representative:
• Install Uponor systems according to
the installation instructions of the
manufacturer. Failure to follow the
instructions and installation guidelines
can result in system function failure.
• Do not use PEX tubing where
temperatures and pressures
exceed ratings.
• Do not expose Uponor AquaPEX White
tubing to direct sunlight for more
than 30 days; do not expose Uponor
AquaPEX Red or Blue tubing to direct
sunlight for more than 90 days.
• Do not weld, glue or use adhesives or
adhesive tape on PEX tubing.

• Do not apply open flame to
PEX tubing.
• Do not install PEX tubing within 6"
of any gas appliance vents, with the
exception of double-wall B-vents or
plastic vents, which have a minimum
clearance of 1".
• Do not install PEX tubing within
the first 18" of a connection to a
water heater, unless otherwise
allowed by code. Follow your local
code requirements.
• Do not install PEX within 12" of any
recessed light fixtures, unless the
PEX tubing is protected with suitable
insulation or the can light is Insulation
Contact (I.C.) rated.
• Do not install PEX tubing within 5 feet
of direct view from fluorescent lighting
without sleeving the tubing with a
UV-blocking material.
• Do not solder within 18" of any PEX
tubing in the same water line. Make all
sweat connections prior to making the
fitting connection.
• Do not install PEX tubing between the
tub/shower valve and tub spout.
• Do not use PEX tubing for an
electrical ground.
• Do not spray on or allow any organic
chemicals, pesticides, strong acids
or strong bases to be exposed to
PEX tubing.
• Do not use petroleum or solvent-based
paints on PEX tubing.
• Although PEX tubing does not attract
rodents, pests and other insects, these
uninvited guests can have detrimental
effects on PEX system integrity as well
as duct systems, electrical systems and
other integrated systems in a home.
Property owners should take steps to
eliminate pests.
• Do not subject PEX tubing to impact.
• During remodeling or ceiling repair,
take appropriate precautions to protect
the tubing from damage.

You may temporarily affix adhesive tape to
Uponor PEX tubing 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.
