2nd: Wellmate quick disconnect tanks, the classic models were holding up but when they went to the quick disconnect, they started having problems. Pentair states they are not having problems (Right). I had to put air back into the air cell to find a very tiny pin hole, which you cant really see in the picture at the bottom part of the air cell.

I got a Wellmate air cell from their classic model WM-14wb, 21inch diameter & 41inch long, to fix the problem. It was either I found something that worked or I was going to dig back up the tank, since Pentair discontinued the PSC-35-10, 21inch diameter & 37inch long. I did go back with sand & didn't dig it myself because it was all sandstone.

I believe you said that you use to have a pit? If so, did you ever put a heater in your in your pit. I find them all the time here without a heater & their old bladder still working.
Only the bottom of the tank has water. So if the top of the tank is 18" below ground, the bladder and water will be well below the freeze level. Unless it sits unused for a long time, the bladder will be the same temperature as the water. Bladders or diaphragms in tanks can handle a pretty wide range of temperature. The bending back and forth from the pump cycling is what will eventually get them.
