The OEM well pressure tank sh*t the bed. After 16 years it started to give it up. Actually, there was some corrosion around the rubber air fill valve that allowed the air to seep out around the valve stem. Got away with recharging it and not bleeding down much for several months, but lately it got worse to the point it was too much of a PITA. I was surprised to find it was only a 20 gal tank so I went to a 34 gallon squatty body tank so it could still fit inside the pumphouse. Amtrol is really proud of their tanks ($$) but their construction quality is the best available. Hopefully it'll be here long after I am. Went with lead-free brass piping to tie into the PVC and installed PVC unions for easier future maintenance. One of those deals that you couldn't do much about but suffer in the sun and get r done. I got the union style tee fitting because in the event I ever have to do this again, it'll be a simple matter of turning off the pump, shutting off the valves, draining the tank and swapping it out. A 3 hour job turns into about 20 minutes tops. Whole lot easier now - for the next guy.
