Water Pump Pressure Switch Adjustment
The current setting is to pump up to 90 psi and shut off. When the pressure drops to 45 it will turn back on and pump to 90. If you wand a more even pressure reduce the differential pressure. Reducing the differential to 20 the pressure will stay between 90 &amp; 70. this will cause the pump to cycle more often than its current settings. If the pump is cycling rapidly the pressure tank may have lost its air charge.
