What if a tube breaks in the floor?
With many miles of tubing installed in the past 25 years, not a single break has accrued. Should an accidental damage accrue, such as driving a nail into the tubing, this can easily be repaired with a coupling. The tubing will withstand an excess of 100 PSI at 180 F and is used in a typical installation at less than 10 PSI and less than 160 F.
