I’ve used the compressor four time with no issue then yesterday it popped the top four times. I kept turning it off and on the last time left the top off and let it fill my bottle and it just stopped on its own.Is this a new compressor startup or a new problem that wasn't previously happening? Only way the cap comes off is with a rapid increase in pressure inside the tank. IF the compressor head has a leak high pressure air to coolant passage this could happen. If something upon startup pushes on the plastic tank side it can have a squeeze effect. Can you see air bubbles inside your tank?
