Gas Lines Must Be Bonded

Bonding gas lines at meter

In February 2014, House Exam inspectors began to inform our home inspection clients and agents about Corrugated Stainless Steel Tubing (CSST), a yellow-jacketed, flexible gas piping material used in home construction around the US since the mid-to-late 90s. I posted “Home Fires Traced To Gas Piping (CSST) Not Properly Installed” back then to give consumers a heads up about the importance of reporting deficiencies in this kind of gas piping.  At that time, House Exam home inspectors began to write up deficiencies when we observed them at a home.

Since that time, there has been a lot of controversy over the yellow-jacketed variety of CSST. There have been a number of law suits, financial settlements, as well as claims made by both CSST manufacturers and those who think the material itself is defective. In mid-July scores of home inspectors met for an entire day in College Station to hear from experts on the subject. Reflecting the growing controversy, our licensing agency, the Texas Real Estate Commission, has taken steps to begin to educate the home buying public, related to gas piping systems in the home.

On September 1, 2015, home inspectors in Texas will be required to add a new deficiency to their list of mandatory safety reporting: “lack of bonding on gas piping, including corrugated stainless steel tubing (CSST).” Specifically, if inspectors cannot observe that the metal gas piping in the house is bonded (that is, connected properly by a bonding wire) to the electrical grounding system, we are to report such a condition as an electrical deficiency, and recommend further evaluation by a licensed electrician. Current thinking among gas industry and electrical code authorities, is that bonding of these gas lines may be more critical, where CSST is present for the gas piping, than where rigid black pipe has been used. Although the new TREC Standard makes no such differentiation. Instead, inspectors are to report lack of bonding on gas piping as a deficiency, no matter what material is used.

Hazardous positionHouse Exam inspectors have had a policy in place for more than 18 months, to report improperly installed CSST as a deficiency, and to recommend further evaluation by a licensed plumber. Examples of improper installation would include such conditions as: routing the tubing across the decking in an attic, where foot traffic could damage it and cause leaks; routing tubing close to the roof decking, where nails could puncture the tubing during a roof replacement; not properly suspending the tubing for safety, and many more. CSST under roof deckingThese conditions require that a licensed plumber make certain that repairs are made, and then test the gas lines for possible leaks.

We will keep our clients, agents, and the public posted on the issues related to CSST. Remember ALL Texas inspectors must begin to use the new report form REI 7-5 on or after September 1, 2015. And all inspectors must begin to look for bonding of the gas lines to the electrical grounding systems on that date, as well. House Exam inspectors have been reporting deficiencies in the piping since early 2014, and we have been using the new form since early July.

As first time buyers, my fiancé and I were initially very nervous and unsure of the inspection process.
Adam took time to thoroughly explain the process and made simple recommendations as we walked through the house. He was very professional and patient with our questions!
The report was detailed and easy to read. We presented the home owner a copy to make negotiations- he commented how thorough it was and wished he used your services years ago when he first bought the home! We are very pleased and thankful for your services- happy to recommend you to friends and family.

"We would like to commend Adam on the thorough job that he did at our home inspection.
“Adam found a very small leak that many people would have missed. When this leak was tracked down, it was determined to be either in or under the slab. Exactly what we did not want.
“We turned the house down.
“The value of your service was outstanding because it saved us many thousands of dollars, as well as the time and headaches it would have cost to repair the leak.
“We certainly will using House Exam for our future inspection needs."

Thank you for this unusually thorough inspection report. I’ve had a number of inspections run in Texas and California, but yours is easily the most thorough I’ve ever read. As an out of state purchaser, the inspection is that much more important since I can’t see the property first hand, and you have helped us significantly. If you ever need an out of state reference, I’d be very pleased to describe what a great job you’ve done for us.
Best regards,
