To improve water pressure from a water well, turn the power off on the water pump that is connected to the well, and locate the air fill gauge on the top of the pump. Use a tire pressure gauge to check the air pressure, and check the pressure reading on the gauge in the pressure switch box. Remove the cover on the pressure switch box, and adjust the screws inside the box to increase the water pressure.Continue Reading
Typically, the 1/2-inch nut is turned clockwise to increase the cut-in setting, which signals to the pump when to turn on as water leaves the pump, and the 7/16-inch nut is turned clockwise to increase the cutoff time, which signals to the pump when to turn off after refilling with water. Turn the power on, and test the pump.
After reaching the desired pressure levels, connect an air tank to the air fill valve, and add air until the pressure is 2 to 4 psi below the cut-in setting. Replace the cover on the pressure switch box. If the pressure is still too low, consider purchasing a variable-speed water pump to remedy the problem, or install a second pump if the demand for water exceeds the capabilities of the existing pump.Learn more about Plumbing
