Newbie here.

For the past few weeks we have had air in the water lines apparently. It's just a very annoying thing to hear/experience a shower sputtering, faucets do the same thing and so do toilets. The other day I heard the water softener cycle and the discharge line was blowing some air bubbles; so air apparently is getting there too.

We are on a home well system (pump is in the well head, not in the house).
I checked today:
leak down after water pump cuts off - ~2psi loss after 10 minutes based on the gauge on our water line between air bladder tank and well pressure solenoid
removed well head cap and listened for water draining back into the well - didn't hear anything

Any advice on what to check or what the issue(s) could be?
