What doc is needed for a + plus hydro?

[captain]

If the "+" was originally stamped on the tank, it can be overfilled by 10% so long as the tank's vis and hydro are current.

Incorrect. The tank MUST QUALIFY for the + at the time of any hydro to be + rated for the following years 5 years the test is good for. Just because a tank was stamped with a + originally or in the past does not mean it automaticly can be over filled 10% if the current hydro date is not acompanied by the + stamp because not having the plus stamp means one of two things, either it did not qualify for the plus or the necessary calculations or information was not done or unavailable.

No + stamp behind the current hydro test date no 10% overfill allowed.

This is a requalification ( hydro test and visual) flow chart and CGA C5 page 12, see special filling limits.

So, any hydro shop should have on hand, copies of the relevant CGA documents (and probably the CFR) and should know EXACTLY how to do to '+' rating. It may turn out that the hydro shop has never done a '+' rating (they might specialize in fire extinguishers or SCBAs) but they should know how to do it or, at least, be able to research it.

That a dive shop knows less than nothing about hydro is not surprising.

Actually it would seem a dive shop that does hydros in house should be able and willing to do + ratings if not at the same cost of a regular hydro at least at a slight extra cost as another way of generating more revenues and customer satisfaction.

As I said in a previous post the general commercial gas users couldn't care less about + rating because it offers no advantages to them like it does to diver.

never mind

you need to reach out to a 'tech' oriented dive shop, they will know who has a clue in town about performing "+" hydros. Most of my tanks are HP ones, but I do have a few LP ones, and as I take them to get hydroed by knowledgable (Techie) dive shops, I don't worry about digging up obscure DOT regulations/paperwork, the tanks just come back all "+" rated, I pay my bill, walk out the door, and am good for another 5 yrs! (thankgoodness you're not in Australia, I think they have to do YEARLY hydros! )

I wish there were something like that around here. Most of the stores around here focus on "travel scuba": they dive way more in Grand Caymen than they do in the Great Lakes... The couple that don't are competent stores, but they don't go beyond their comfort zone. As a business, that might be a very reasonable way to run a store (and not unreasonable for the majority of their customers), but for customers that fall outside of their comfort zone (like me), it can be frustrating...

Of course, it's unlikely any business is going to be a raging success focusing on customers like me. I fully understand that I am... unique... in my perspective. I'm a Type-A triathlete-type person. Nearly all dive stores I've ever seen are laid-back relaxed dudes. Oil and water...

No, not correct. A hydroshop by law MUST have on hand copies of relevent CGA Documents, as listed in 49 CFR. And MUST have the latest copy of 49 CFR (Or the ability to access it electronically.

If a hydro facility does not have these documents, the DOT can assess a fine of $600 to $1200 for each one missing.

 

[duckbill]

Umm. That's what rstofer said. Where's your disagreement? They should have it because they must have it, or else.

I must understand it, because I should understand it, and you would understand it, if you could understand it.

 

[akdeepdiver]

In the eyes of the DOT (And I do know one Hydroshop that has had this argument and lost it with a inspector, and no it was not my hydroshop.)

Should = Implies it is optional.

Must = Not optional. Needed on hand to operate.
