My home is almost 11 years old in Calumet Grove. We have CSST in our attic. I had Mike Scott Plumbing (licensed for gas installation and repair) come to my home this week to discuss this issue. Their gas man (25 years of gas experience) stated that a direct hit from lightning will breach almost anything, including CSST or hard pipe. He checked the CSST in my attic and it was bonded and grounded as required. We have a gas water heater, Furnace A/c, and Dryer. Options are: (1) Leave as is. (2) Replace the Attic CSST with hard pipe coming in my garage either along the floor or ceiling wall at a rough cost of $650. (3) replace all gas appliances with electric - New Furnace / Water Heater / Dryer + cost of electrical $$$$?. (4) Add lightning rod protection. Last week A-1 Lightning protection stated they could install a complete system(around $1800ish), with grounding the CSST and the manifold where the lines split in the attic to the appliances. If your specific lot has more sand soil than clay they will double the amount of grounding rods supposedly to compensate. Electric or gas won't matter much if you get a direct hit. I have not decided what to do or not do. Any one else in this position that has?
