Must be the season I had to replace the flex hose from the well head to the intake to the holding tank last week ( hole is still open, hoping that the fix holds, seriously contemplating filling the hole with straw and some serious covering if there is a problem over the winter). Since then, water pressure drops out 1/2 way through a shower *sucks* How do you "re air regulate" the tank? I really think that since the tank lost water, that this is what needs to be done. I know I have to bleed the tank. Then what? I have access to an air compressor if needed.
