Plastic pipe failure can be catastrophic and leads to millions of dollars of property damage every year. These failures have a number of causes, including:
+ improper selection of materials
+ manufacturing or fabrication defects
+ poor part design

CPVC pipe has been used successfully for decades. However, if exposed to certain chemicals, premature failure can occur. Plastic Expert Group was tasked with determining if the applied caulks and sprays were compatible with CPVC, or if the use of these materials led to the failure of the CPVC pipes.

All caulks and sprays were removed and analyzed at the molecular level to determine their exact chemical makeup. Our scientists were able to determine each product’s identity with >99% accuracy. It’s as accurate as reading a label.



Plastic Expert Group concluded that each of the materials in contact with the CPVC pipe was incompatible. These incompatibles were both known and well documented by the caulk manufacturer. Because of the application of these products, premature failure of the CPVC pipe occurred.
