My mother had a 2 stage air compressor that would no longer run that she gave to me. The only way I could move it by myself was to pull the motor and the compressor off. Everything came apart with no issues and I brought it home. Took the motor to a local shop near me, it was a simple fix and 53.00 later I was on my way with the motor. The whole unit was coated with a layer of oil and dirt so I placed it in my heated shop for cleanup. This morning when moving the tank around I could hear something clunking around inside it. I put the tank up on blocks so that I could get a pan under it and pulled the bottom plug. I had to poke a whole in the crud at the bottom at which point I started a stream of water that added up to 7 gallons of moisture. 14 hours later the ice cube inside the tank is still melting. My mother who is 86 years old used that compressor for 21 years and never once drained the moisture off, said she was not aware that it should be done. The compressor was always set to automatically run when the pressure got low enough, you can only imagine how many times it cycled before the motor gave out.
