I was just wondering what would cause it to only charge to 32 psi.
Either your gauge is bad or you messed with the pressure switch.
Your tank is bad and needs to be replaced; not refilled with air. The reason the pressure in the tank went up is that water is getting on top of the bladder. By draining it (partially) and putting air in it, you have just made a temporary repair. It will keep getting worse until you change it.
Well X Trol makes a great tank. The WX 203 just wasn't one of their finest accomplishments.
