So I dropped by Scubatoys this afternoon, to pick up one batch of tanks and drop off a second batch of tanks (for assorted visuals/hydros) and the gentleman at the counter mentions there is a '5 hydros and you're done' limit on the maximum number of hydros tanks can go through. (it's not a Scubatoys enforced limit, but apparently from their hydro services supplier.) I doubt this is a DOT or legal requirement but perhaps this hydro shop has implemented their own strange rule ?
I'd brought by a few recently acquired galvanized steel tanks and the gentleman cautioned me to shop for recent vintage tanks, with the least number of hydros possible, so as to postpone for as many years as possible hitting this '5 hydros' limit.
Anyone else ever heard of such a thing ???
