The minimum tank pressure must be at least as high as the pressure needed by any water-using fixture or appliance. Many require at least 10 psi to operate properly. Water treatment units, water softeners, clothes washers, and dishwashers may require higher water pressure to operate properly; possibly as high as 30 psi or more.
