Thawing Frozen Tubing
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.
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.
If the tubing experiences an ice blockage, thaw the tubing using one of the
following methods.
• Pour hot water over the affected tubing area.
• Wrap hot towels around the affected tubing area.
• Place a small, portable heating device in the area to heat the space and thaw the ice
blockage from the tubing.
• 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.
• Use a commercial system that pumps hot water to the ice blockage and returns the
cooled water to be re-heated.
