Stop in for a cup of coffee

I understand the water logging on tank with no bladder. But on a bladder tank, the only way it should ever water log is if the bladder fails. If it's a vertical tank that is plumbed like that, I could see it still working as you said even with a failed bladder. But, this is horizontal,so I believe once the bladder fails, your screwed. I could leave higher air pressure on it for a while and maybe it would push any water through... I will mess with it again sometime this week and tap on tank to see where the water/air is. I didn't do that.

And it does not matter what size or shape the tank is (a tank is a tank and your water and air will take shape to the shape of the tank and air is lighter than the water) it has a top and the air even if pumped from the side will be at the top. I know you know all the principles of displacement even better than me. But it helps me explain what is going on. If your pump keeps running and you have no to little pressure your tank is water logged. Now you need to find out why.
