Do you ever dump and refill your bailout tanks?

only if it analyzes different than what it was filled to.

How is it possible?

"Dump" never.
Eventually I feel guilty that they are 2 or 3 years past hydro and I boost the gas out into my bank or into other cylinders
Helium only really leaks out of the lola manifold hose. I have 6yo BOs of 9/71 that are still 9/71.
If the O2 is dropping there was major water injected at the time of the fill.

The power of the booster. Boost into one of the million other tanks I have. I will dump part of a fill of say I have 3500psi or 30/30 and want the same psi of 21/35 or vice versa. Sometimes it’s easier to dump a few 100 psi
No. I'd never dump my bailouts. It would be a waste of money and time. I've had trimix bailouts that have been full for 3-4 years.
They've all past visual and some of them are out of hydro at this point. I don't have any problem dumping nitrox bailouts since that that gas is relatively cheap but I've got 18/45, 15/55, 10/70 bailouts where the gas probably is worth more than the cylinder at this point. I will still periodically analyze them if they haven't been used in a while, check pressure and occasionally top them off a couple hundred psi.
If they start getting well past hydro then I'll just boost them into another bottle or use them for diluent.

Find a student who is taking the class that needs bailouts. Let them bail, hydro, charge them an at-cost refill. You are back to an in-hydro tank and a fresh fill. Someone else bought the gas. the student got a deal on the gas and borrowed bailouts. Everyone wins.

Does anyone do bailout ascent practice then, or just simulate shallower with cheaper gas?
