Corrugated stainless steel tubing (CSST) has been a favorite of U.S. contractors the past two decades as a flexible alternative to the rigid black iron pipe used as gas lines in residential, commercial and industrial structures.
CSST is easier to install and offers a substantial savings in labor costs for builders. When installed properly, CSST is safe, strong and offers fewer risks for gas leaks than threaded piping. When put in incorrectly however, CSST is a potential fire hazard that could lead to massive damage to your home.
“If you’ve had a home built or remodeled since 1988, it could have CSST pipe, so do yourself a favor and find out if you do and if it’s properly bonded and grounded,” said Angie Hicks, founder of Angie’s List . “Too many homeowners have literally watched their homes burn to the ground because they didn’t check or didn’t even know they needed to.”
A recent poll of Angie’s List members showed that 44 percent don’t know what type of gas piping they have in their homes. Reliable, well-trained home inspectors can easily determine whether CSST pipes are properly installed.
Angie’s List offers some tips to keep your house safe from lightning-related fires:
- Know what type of gas line you have in your home. If you are looking yourself to see if you have CSST piping, you will typically find the flexible pipe encased in a yellow plastic covering. CSST is often connected to appliances, such as a water heater. It also can be seen in attics and basements, and along floor joists. If you do have CSST lines, contact a qualified electrician or plumber who is certified to work on CSST, to ensure it is properly bonded and grounded.
- If there is lightning in your area, unplug appliances and turn off your air conditioner. Avoid using the telephone or running water. Draw blinds or shades over windows to help shield the inside of your home and your family members from breaking glass.
- If your home is struck by lightning, turn off the gas at the main shutoff valve. If you smell gas, evacuate the home immediately and call emergency services.
