Question Dive shop won’t hydro test tanks due to previous hydro test stamp placement?

[Still Kicking]

Do you own a file?

Hope you're not suggesting filing off the phony hydro stamp? That would get the tank condemned.

The hydro shop guy said since the stamp was very superficial, I could sand it off. But then he seemed to quickly change topic which made me wonder… I certainly won’t do that, but made me doubt his competency.

How can you doubt competency when you're the one with the thread and all the questions
with all the dud answers

If I were a particularly astheticsal tank guy I'd get rid of it
and nothing would be compromised or condemned at all

Leave the fake stamp alone. Trying to erase it raises more red flags and could be grounds for the tank to fail VIP.

DO not use a file!! That will condemn a cylinder. Use an blunt end of a stamp and an air hammer/chisel and erase the the offending numbers.

At this point much of the surface disturbance is from the paint being stamped. If one wants to do anything, strip the paint off and repaint it. A couple of coats of paint will likely fill in the marks such that they will be hard to see.

Which will also raise questions from a competent VIP tech. When asked about the repaint "To obscure weird tank stamp marks ..." is not likely a good answer. Better to leave them alone. "15 years ago, when the tank was owned by somebody else, it seems that somebody tried to fake a hydro mark. When I got the tank, I had it hydro tested by a legitimate requalifier to establish it is a good tank - that's his RIN in the middle of the new hydro mark" is a lot better explanation. I don't know why the presence of the old marks is a reason for concern to some.

New test, new mark. Good to go. I'd accept that as part of a VIP inspection any day.

"Oh, I filed off bogus marks I didn't want you to see" is gonna be the end of any inspection at that point.

I know you have your won compressor, but if I were in your shoes, when they come back from hydro, I think I'd have to take them to the hop that turned them away for a fill.

You did say hydro and visual - is that the visual that's part of the hydro or a separate VIP with external sticker?

The guy at the shop said visual and hydro but I’m not sure if it’s going to be a separate sticker.. I’ll let you know when I get the tanks back. I do plan on doing what you mentioned to see if the shop is willing to fill the tanks after-all.

Do you own a file?

I do.. but wouldn’t putting a file to the stamp cause

1) Suspicion as the yellow powder coat will be gone with an obvious metal patch exposed

2) Compromise the integrity of the tank?

Is it written somewhere in the scubaboard rules that once a thread reaches a certain number of replies somebody has to mention guns?

If it isn’t, it should be.
