abadinalbany is an unknown quantity at this point

My little bro's thinking it might need purging?

how long should it take for a can to empty? it seems like it only pumps in until a point, then backpressure cuts it off until the compressor runs again.

Shake the can while doing this, turning it from upright to sideways. 10-20 minutes is not unheard of.

The compressor should be running during this so you can monitor the low side pressure. When the compressor is not running, it will take much longer to empty a can as the pressure differential is not as great.
