I was using my 20 gallon campbell hausfield air compressor. It's a 3.5peak HP single stage oiless, 110v model.
I was sand blasting (knifedogs dog tags actually) and I started to see some water come shoot out with the abrasive. I don't have a line dryer but it had been some time since I drained the tank so I thought I should do that. I used the relief valve to drain the pressure down to about 40psi. The drain valve is on the bottom so I lifted the tank on it's end the long ways to get wrench on the drain valve and loosen it. I put it back down level and loosened the drain valve all the way. The remaining air pressure was quite strong and it really blew out the moisture when the valve came undone. I rocked it around and drained any other remaining water and screwed the valve back in. When I plugged the unit back in, it won't work.
I'm thinking two things. There is a tip over switch internally that didn't like getting tipped on it's end (it is a closed "oiless" system) or the pressure switch really didn't like me opening the drain valve that way.
Has anyone had any experience with this?
