I was fortunate with my expansion tank. It was full of water but before removing it I tried pressurizing it. For me, it worked. I was able to bring it up to 65 psi and it is working.
NOTE: To add pressure I first shut off the cold water into the tank and then opened a hot water faucet. By doing this I had no back pressure on the bladder so the only reason it would gain pressure is if the bladder was still good.
I doubt I had very nasty water in the tank - that might be a sure sign that it was truly bad.
