The Common Problems
When water freezes solid in a HDPE pipe, it will not rupture it, but the pipe will expand with the ice. Obviously, the application of heat to the frozen section is really the only practical way to thaw it. But for safety considerations, and to avoid damage to the pipe, this must be done very carefully. One method is heat tracing.
