  • Corrugated Stainless Steel Tubing (CSST)


    I have read negative reports recently about CSST in gas installations. I recently had a length of black iron pipe replaced due to rust-out because of contact with the soil (due to poor support in crawl space) under an old farm house in rural Miss. The service man from the local propane supply company used CSST for the repair. Is this not a professionally accepted method of gas plumbing? Thanks

    Is it accepted? Yes. Should it be? I don't think it should. Is it something you should worry about? No.

      It is absolutely fine. It is not as good as black iron but less labor intense. It is wrapped with a plastic insulation to protect from the elements. All csst like all gas is supposed to be grounded. It cannot be used in the ground unless it is sleeved. If you ever need to use in the ground they sell it in plastic which is approved for underground use. Plastic is for underground only ! Hope this helps.
