Question Is the “+” still in use for LP tanks?

[RIHappyDiver]

Two different shops have told me that LP tanks are now stamped with a “-“ if they are no longer good for the 10%. Is this true?

Thanks,

They are full of bs.

find a new shop, that's not part of the DOT ruling. If they don't have a + mark from the most recent hydro then they aren't eligible for the overfill but that's usually from lazy hydro shops

Which shop is this

The first was FireEx in Portsmouth, who did their own hydros and fills, and always filled to 2600, even after no +. They no longer do scuba tanks. The other is East bay, who doesn’t do their own hydros, but fills to 2600 without the +. So, I’m not complaining about the fills.

What everyone is saying here is what I understood to be true. But when two different places, the first of which I spoke to the guy who did the hydro, say the same thing, it made me wonder if I was working on outdated info.

Run away from that shop quickly. There is so much misinformation out there on SCUBA tanks - it's amazing to me. It doesn't seem like that hard a concept. I do think it's silly tanks are still made and rated the way they are - the + is such an old thing - new tanks should just be rated (I think other countries have only one value) and be done with it. Of course if that were done, getting my old '72s + stamped would be even harder than it is today.

I'm concerned about the lack of knowledge

No.

If you really want the straight poop, call the DOT. They answer the phone. They're pretty friendly when it comes to compressed gas safety questions in my experience.

I recently saw hydros on HP tanks with a +. The level of incompetence at some retest facilities is stunning.
