You got it! Several years ago I came into a set of the Navy non mag tanks. As you know these are not DOT spec tanks and can't be hydroed and stamped although they had stamps of hydros being done in the 70's by dive shops. These stamps did not have the 4 digit code identifier now used, just a symbol the shop had chosen for itself.SurfLung wrote: ↑Mon Apr 05, 2021 10:11 amI got a call from Sea Hunt Jerry last night with pretty much the same opinion as Allan and Tom. And I think from here on, my four sets of Twin 38s will forego the risk of hydrotesting. They are a known commodity, I know they've already passed a hydrotest and I have not abused them since. So, why would they need more testing? And YES, I fill them myself so I don't have to please any dive shops.
But when we get a new (old) tank, I guess I was/am feeling like doing the hydrotest gives me a clear sense of safety in going forward. Rich had a new-to-him set of Twin 45s and I had a new-to-me pair of Vigo 18 tanks. As we've seen in the past, when we find the right guy to do the hydrotest, he seems to know the situation and the tanks almost always pass. Doggone HydroStat had a guy named Mike that was great. He wasn't there this time.
And then also, we're not immune to the constant brainwashing. We're "doing the right thing" to get our tanks tested for the safety of humanity. How many times do we get a slap in the face as a reward before we wake up? Thank you guys for the good advice.
