Oldred you are right. But I don't have much choice. I could possible run it out thru the high combustion air vent to the overhang and back in the garage again. i think I will have to take my time and look for my options on how to run the pipe.

I changed the oil in the compressor last night. It was really dark and thick. I also changed the electrical plug to match the 240v outlet in the garage. I put in some Mobil 1 10-30 per the manufactures recommendations. I fired up the compressor to get some air in the tank to blow out any water that might be in the tank. Boy was I surprised. After one red rag full of water and two paper towels I thought I would collect the water to see how much was in there. The compressor spit out 3 more inches or water and pooped out a mess of oil/ water goo. The goo had a slight oil smell. Not as bad as some other compressors I have had. I don't think this compressor has ever been drained or the oil changed. I bleed of some air out of the pop off valve with a paper towel around it to see how much oil was being blown out. To my surprise there was no trace of oil on the paper towel. I am going to remove the bottom bung and see if I can clean out the tank somehow. If nothing else just let it sit with the bung out so all the goo can drain out.

This is a pic of the water/goo I collected from the tank. Nasty looking uhh?

I would not worry in the least about that tank, what you have there is normal although there is a lot of it but that comes from not draining the tank every day and I don't think the tank will need any further cleaning except for regular draining. That goo and oil smell is nothing to be concerned about when drained from the tank but if you were to get oil from the air line itself that would be another story, however I seriously doubt that you will have that problem. That goop is normal and is something I like to point out to anyone considering using compressor air for breathing air when painting, I would not want to think I was breathing that stuff

That would be like the old days when kids were breathing the pan spray called PAM. It would coat your lungs and kill you...this would too I think. Can't say that it ever crossed my mind to use this air for breathing..common sense kicks in for some of us I guess.

You would be surprised at how many people do this. There are engineered devices that can use compressor air for this purpose but they are well filtered and use a carbon monoxide monitor for safety. The engineered outfits may be ok but I have seen some pretty scary looking home made set-ups that I would not use under any circumstances and unfortunately these are fairly common.
