Failure of CPVC piping
CPVC fire sprinkler pipe. Why do we use it? This is a product that the fire protection industry has used for years, but now we seem to be seeing it fail at an increasing rate. What is causing this? There is an excellent article on this that I feel all should read. It can be found on the web at:
It identified 4 basic causes of failure. Contamination, Installation practices, Manufacturing defects, and other. Of all of these contamination is the most prevalent and also in so many ways beyond our control. If we get a good product that is not defective, If it was shipped and stored properly, Then we have to make sure that the installer is well trained and all of our products are compatible with the pipe. But after that we are at the mercy of so many others.
Therefore it is important to document the products we use and practice good CYA in informing the customer of the risks associated with possible contamination of the pipe by other trades and by service personal after the project is turned over to the owner.
