Reforming kinked piping
If the piping kinks and hinders
flow, perform the following
steps for an easy repair.
1. Straighten the kinked portion
of the piping.
2. Heat the kinked area to
approximately 265°F (130°C)
with an electric heat gun
(approximately 450 watts
of power). Apply the heat
evenly until the piping
returns to its original size
and shape. Do not use an
open flame.
Caution: Only heat the
Uponor AquaPEX piping
long enough to remove the
kink. Remove the heat
source from the piping as
soon as possible; excessive
heat may harm the outer
polyethylene layer. Damage
to the outer layer is only
aesthetic; it does not affect
the performance of the
piping.
3. Let the repaired Uponor
AquaPEX piping cool
undisturbed to room
temperature. When the
piping returns to its original
appearance, the repair is
complete.
Caution: The surface
temperature of the
piping must not exceed
338°F (170°C). DO NOT apply
direct flame to Uponor
AquaPEX piping.
Uponor AquaPEX piping
repaired according to these
recommendations will return
to its original shape and
strength. If Uponor AquaPEX
piping is sliced, punctured or
otherwise damaged beyond
the capacity of the crosslinked
memory, it is necessary to
remove and replace the entire
section.
Note: Do not weld PEX or
attempt to repair with
adhesives.
Caution: When reforming
kinked piping, protect
sprinklers and cover
plates from excessive heat.
These devices are heat
sensitive. Excessive
temperatures may cause the
glass bulb of the sprinkler to
burst, activating discharge.
Note: In accordance with
UL and C-UL listings, when
protection for the piping
and fittings is provided,
the minimum protection
consists of either:
The following section provides instructions for reforming kinked
piping. Bend supports are available for Uponor AquaPEX piping
and may be used to facilitate 90-degree rigid bends.
