...About those "imaginary" compressor explosions....

About 3 years ago after I did my garage over I moved the compressor outside and as of yet I haven't built a shed around it....Its under a tarp and I dont use it much. I drain the tank on a regular basis
Its singe stage with a 60 gallon tank, a Sears unit that has to be a good 35 years old
I looked the other day and I didnt see the tag indicting the tank Is ASME. Im not sure of what pressure its set to shut off at but I think about 125
Now seeing that im old and worry about everything, im concerned about the tank
There is a big plug on one side and I was thinking of removing it and getting one of those probe lights and look inside to see the condition of the tank
Or maybe its time for that new 2 stage I always wanted
