    Default Copper piping with other gases

    During an inspection yesterday, I found a soft copper pipe used for gas. I know this MAY be an issue if the copper is not tin-lined. However, on this house, there was a fuel storage tank outside. I therefore have two questions.

    1) Is non tin-lined copper pipe unsafe with ALL gases, or is LP/propane ok?

    2) When you see such a fuel storage tank, how do you know which type of gas is in it? The homeowners were not there to ask.

    Thanks,

    Dave

    I can't say I have ever heard of copper pipe with a tin liner or coating.

    There are only two fuel tanks you would typically see.

    1. Propane
    2. Fuel oil tank

    Made me think about what might be found and if it was not obvious from experience what it was.

    What types of gas/fluid you think would be in the storage tanks that are not marked? Made me think for a moment what you might find; #2 Heating oil, diesel, kerosene, hydrological fluid, lubrication oils, jet fuel, petrol (gasoline), propane (LP).

    Determining contents; tank design, fluids' appearance, smell, taste, flame, what it is attached to, type of pump connected to tank.
