The home needs to be inspected, and proper bonding (if not already present) must be installed to yellow flexible gas lines to help protect the home in the event of a lightning strike. Especially if they are not protected with Bonding to ensure electrical energy is carried away from the pipe (versus carried by the pipe). CSST flexible gas lines in the attic are a prime candidate for damage from lightning strikes. Most homes have gas lines in their attic, walls & basements. If you own a home that has CSST flexible yellow gas lines and was built prior to 2007, this fire-risk may exist in your home. Only an inspection will determine if the gas lines are safely bonded as required by today’s Building, Plumbing & Electrical Codes. These homes may, or may not have bonded gas lines.
Flex type gas pipe code#
Homes built with CSST flexible gas Lines before the Building Code required bonding were built correctly to the Building Code at the time they were built. Building Codes, including Plumbing & Electrical Codes were updated based on the growing incidents of house fires.

This code came in as a response to damage to flexible gas lines and fires in homes struck by lightning. As you can see, there is a significant multi-year gap in which Building Codes did not require proper bonding of flexible gas lines. Confined gas fumes that are in a closed room or an unoccupied home can lead to an explosion.Ĭonnecticut Building Code has allowed CSST gas lines since the 1990’s. Building Codes requiring bonding of CSST flexible gas lines came into practice no earlier than 2007.

Lightning-strikes have a documented history of creating holes in CSST gas lines, allowing the gas to escape and dramatically increasing the risk of gas-fueled fires in the home. The risk is tremendously reduced when CSST flexible gas lines are “bonded “ (BONDED DEFINED: Connected with wiring to take electrical current away from CSST flexible gas lines in the event of a lightening-strike on or near the home). It also describes a safety hazard and code changes due to the history of house fires associated with CSST when lightning strikes nearby, or worse yet, the home itself. This article details a potential hazard related to Flexible, Yellow, Corrugated Stainless Steel Tubing (CSST) Gas Lines within your home. WARNING: IF YOU SMELL What you feel is a GAS or propane fume - LEAVE YOUR HOME & LAWN.
