The PSI for your pressure tank should be set at 2 PSI below the cut-in pressure of the pump switch. For most residential systems, the standard setting is 20 to 40 PSI or 30 to 50 PSI, meaning your pressure tank's pre-charge should be 18 PSI or 28 PSI, respectively. This ensures optimal performance and efficiency of your water system. Always check manufacturer guidelines for the most accurate settings for your specific equipment.
