Replacing propane tank?

Our propane tank on our 25-year old Class C is looking pretty rusty. Sometimes the main valve will leak in between the open and closed position. I read here that it was a lose packing valve but looking at the valve I see nothing to tighten.

Anyway I'm thinking it would probably be a good idea to replace this tank given its age and state.

Any idea how much this job would cost?

    I agree.

    The valve can definitely be fixed.

    The tank may only have cosmetic rust and be sound. The real way to tell is to pressure test it, which a propane supplier should be able to do.

    This seems like very good advice to me, as well. If you can just replace the valve (or not—they aren't really designed to be left in positions between fully open and fully closed) and paint the tank and be safe, there's no need to do anything more. Maybe they would recommend inspecting the interior of it or something along those lines; I'm not a propane specialist by a very long stretch.

    You do have to have the tank empty to replace the valve, but then again you need to empty the tank to replace the tank, so there's not much difference there.

    Many propane tanks are in safe regular use that are older than 25 years old.

  • If they are that old, I suggest buying some new tanks and avoid having a dangerous situation. I know they aren't cheap, but a malfunction of the propane system could be a lot more costly.

    And, the suggestion for looking for a couple of used tanks in good condition could reduce the cost.

    I know in some states, a tank in poor condition can be refused for refilling.
  • LP tanks are rather expense. Maybe you could you could find a good used one.
    The valve packing can be replaced, but the tank needs to be empty. Go to a propane supplier.
    If there are no rust pits, but just surface rust, you could just clean it up and paint it.
