      That is true, but not in all circumstances.

        Worked in the area till about 6 years ago.

        I don't miss crawlspaces in converted cottages mid-winter dealing with burst/frozen pipes.

          Damn, I sure have. Especially when a gas line is ran across the bottom of joists in a long run, strapped to it with wire hangers.


          Kinda has the same effect on IPS threads over time; seepage leaks from the vibration/movements of the house through the course of time.


          This time of year when it gets cool outside, people close their houses up and instantly start to smell gas.

          Bad for them, good for me.


          When I see a doped up union with silicone or putty on it.....it was a fitting undisturbed and vibration caused it to leak.

            There lies the problem.
            No need for dope on the metal to metal seal on a union.

            You basically take a strong sealed surface and use something less strong.
            In time the lesser material will yield to vibration, movement or thermal expansion.

            Devine openly mentioned doing this, he got an earful.

              In the older S.F. HOMES,hard piped You had a union behind the stove. Don't want Em elsewhere.
