What is CSST?

CSST or Corrugated Stainless Steel Tubing is a flexible pipe often used for gas fuel distribution to appliances within a building.

 

Japan introduced CSST to the world in the 1980's as an alternative to the traditional iron pipe in order to prevent damage during earthquakes.  Damage to pipes and fittings often resulted in fires.  An added benefit to preventing fire hazards to buildings during earthquakes is that the flexible pipe was much easier to install. 

In the 1990's CSST came to the United States with a great appeal due to the cost savings of installation.  The ability to flex the material rather than cut and add fittings saved builders and installation companies hundreds of dollars per property.  Since 1990, it is estimated that more than 6 million homes in the U.S. have CSST piping installed. 

Why should you be concerned about CSST?

Although CSST provides many benefits in cost savings during installation, one danger presented is when the product becomes "electrically charged".  It has been found that electrical events, like a lightning strike or power surges, can cause damage to the piping often resulting in a fire! 

If you have ever witnessed a lightning strike, you realize that the electric bolt always seeks a route to the ground.  CSST fires often occur when electricity traveling through the tubing and cannot find an easy route to the ground.  This creates a scenario in which the electrical current then damages the tubing, allowing gas to escape and resulting in a well fueled fire which can destroy a home or building in minutes!

In 2007, some manufacturers of CSST settled a class action law suit providing money to fix the problem.  In addition, many manufacturers issued revised installation guidelines in order to prevent fires caused by electrical events.  This included "bonding" the CSST to a ground connection in order to provide an outlet for the electrical current.  

If your property has gas serviced appliances or systems (fireplace, stove/range, furnace, water heater, etc.), it is very likely you have CSST providing a conduit for gas fuel.

What should you do?

First, verify that you have CSST installed.  This requires a simple Inspection by a qualified Inspector.  The Inspector will employ invasive, but non destructive techniques in order to determine if CSST is being used to distribute gas fuel.  He or She will provide you with a written report showing if CSST is found and where it is located as well as if any bonding techniques could be found.  It is important that you follow the Inspector's verbal and written recommendations after the Inspection in order to ensure safety and prevent disaster.
