Your pressure gauge may be broken....If it fluctuates, then you know its not your gauge, but if your gauge always reads 80, it may need to be replaced.

To calculate the static pressure at a depth of 25 feet with a psi of 80, we need to consider that 1 psi corresponds to approximately 2.31 feet of water. Therefore, the pressure in feet of water at 80 psi is 80 psi × 2.31 feet/psi = 184.8 feet. At a depth of 25 feet, the static pressure would be the sum of the atmospheric pressure (typically 14.7 psi at sea level) and the pressure from the water column. In this case, the static pressure at 25 feet is approximately 80 psi, assuming the measurement is taken at that depth.
factory air pressure norm is 80 psi
between 20 and 80 psi between 20 and 80 psi
Optimal household water pressure should be between 40 psi - 80 psi. If water is supplied by public water usually they supply the minimum pressure. If you have more than 80 psi, a pressure reducer is recommended.
