You must drain the tank almost to bottom, switch off the pump and water feed to house . Now put in 27-28 psi of air if you have a 30/50 pressure switch. Put in 37-38 if you have a 40/60 switch. It may be necessary to adjust the pressure switch after observing cut in and out.
The water pressure depends on the residual air pressure in the tank. Normally it should be between 30 -50-psi. Tank air pressure is important, it should be about 27-29 when water is nearly empty.
40-80 psi.
Mechanical pressure will not split water into its component elements.
It depends on which pressure switch you have. The total pressure with a 60-80 switch is about 84 psi.
The air pressure should be 2-3 psi LESS than the pressure switch cut on. If you have a good 30/50 switch, then 27-28 psi air is good. (this is measured when tank is almost empty of water.)Total pressure with this switch should never be more than about 58 psi
You should not really have over 80 pounds of pressure. But a lot of people do. NO -- even with high pressure it should work ok
To replace a 3/4 pressure reducing valve should be $400-$500 9/12/12 md

4,000 PSI working pressure
One tablespoon per day mixed into water should be sufficient.
10 inches of water column equals to how much gas pressure?
The size of tank is immaterial. ALL domestic well water pressure tanks should have 28 or 38 psi when nearly empty. The difference is whether it has a 30/50 or a 40/60 pressure switch on it.
