Newbie with a new compressor (Big Foot) and air tank (6.8L). After a minor issue, the compressor is up and running. However, when I try to fill the air tank, I must be doing something wrong. When I try to fill the tank from empty, it only takes 3 or 4 minutes, which seems incredibly short to me, and the compressor shuts off at the desired pressure. The compressor gauge and tank gauge read the same. So, I'm figuring at this point, I should be able to shut the tank valve, bleed off the pressure, and I'll be good to go, right? Well, the tank valve doesn't shut off the connection between the tank and the compressor. After I close the tank valve, I go to bleed off the pressure at the compressor, but the tank will drain. Embarrassingly, I thought I had a defective tank valve, so I bought another one.....but it does the same thing. This must be operator error. Can anybody tell me what I'm doing wrong?
