These claims have lead to a class-action lawsuit against manufacturers of CCST (Titeflex, Ward, OmegaFlex and Parker Hannifin) installed in homes as of September 5, 2006.Plaintiffs claim that the CSST tubing is not thick enough to prevent becoming damaged in the event of a lightning strike, and that CSST manufacturers failed to warn consumers about such dangers. The defendants claim that CSST is safe if properly installed, in accordance with local codes and the manufacturers’ instructions. According to the Lightning Protection Institute, dangerous CSST has been installed in more than a million homes in the United States.
Identification of CSST
Typically, these products may be visible in attic spaces, along floor joists, above basements, or connected to exposed appliances, such as water heaters. The piping can be identified by its manufacturer’s mark, each of which are listed below:
- OmegaFlex's CSST is stamped with the marks “TRACPIPE” or “COUNTERSTRIKE.”
- Parker Hannifin's CSST is stamped with the mark “PARFLEX.”
- Titeflex's CSST is stamped with the mark “GASTITE.”
- Ward's CSST is stamped with the mark “WARDFLEX.”
Additional bonding to ground is recommended for houses with CSST.
