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.

I just had a home inspected, and the inspector measured the static water pressure at 115 psi. He noted that this pressure shouldn't be above 80 psi and recommended installing a pressure reducing or regulating valve to get the pressure down to 80 psi. He warned that too much pressure stresses pipes, fittings, and valves and can cause any of these to fail. Most solenoid valves on a washing machine or dish washer would not like to see over 80 psi Gage. other valves like faucets and boiler drains my leek sooner but will not be effected as much. The pressure relief valve on your water heater may exceed its 150 psi if heating from a cold take with out a domestic expansion tank, especially with existence of a check valve at the water meter.
