Usually a place that says they will recertify actually wonít.
I couldnít even find out what the requirements are, the filling station is allowed to do a visual inspection
and fill. Some will charge you money
for this and put a sticker on it, which will of course fall off or be washed off, and I donít think is recognized by any other fillers.
There is no hydro done, I do know that, I believe itís actually just a visual and meant really to find excessively rusted steel
tanks, not aluminum. Aluminum tanks are unusual outside of the marine
world, Iíve seen some forklift tanks that are, but thatís it.
I finally gave up and just stamped my own tank, it wonít hold up to real scrutiny of course cause itís supposed to have a symbol that I donít have, but they only look to see a stamped date and fill it.
Iíd like to get it actually recertified , but gave up.
