Update – The Problem with PEX Pipe

In July of last year, an article on the problems with PEX pipe was published.  In that article, one of the things that was described was the fact that multiple failures were being seen in the same line.  The failures that were described were encountered during the same investigation.  However, a case that was investigated last year has been reopened.  At the time of the investigation, the failed section of PEX pipe was recovered and the section repaired and the line placed back into service.  Now, a few months later, a second failure has occurred in the same line that initially failed and was repaired.  What to do?  Replace PEX piping with copper piping, if feasible.  If not, PVC, CPVC  and polybutylene piping can be acceptable substitutes (at this time 1/8/13). An example of the failure observed in PEX pipe is shown in the photograph below.
