Stainless Steel Tubing (CSST)

CSST is a conductor of lightning and, because of this, it poses a risk of gas leaks and fire. In order to protect against lightning strikes, the building owner should install appropriate electrical bonding and conduct an inspection of their CSST gas piping system.

Recently, Unitil has been finding a high number of code violations of CSST gas piping installations that are not properly bonded. Unitil is required to issue a yellow tag warning with a 30-day requirement for the customer to correct the issue. If not completed in 30 days, a red tag is issued, and gas service is turned off until repairs are completed and inspected.

To ensure your home/building and your gas piping system is up to current building codes, please contact a licensed, qualified plumber for an evaluation or for more information.
