The pressure gauge on a well pump is used to monitor the water pressure in the system. The specific pressure settings can vary depending on the type of well pump (submersible or jet pump), the size of the pump, and the design of the well system. However, here are some general guidelines:
Normal Operating Pressure: The pressure gauge on a well pump typically has a normal operating pressure range. This range can vary, but it's often around 40-60 psi (pounds per square inch) for residential systems. Some systems may operate within a slightly different range, such as 30-50 psi.
Cut-In and Cut-Out Pressure: Well pumps are equipped with pressure switches that control when the pump turns on (cut-in pressure) and when it turns off (cut-out pressure). The cut-in pressure is the minimum pressure at which the pump starts, and the cut-out pressure is the maximum pressure at which the pump stops. For example, a common setting might be a cut-in pressure of 40 psi and a cut-out pressure of 60 psi.
Pressure Tank: In addition to the pressure gauge and pressure switch, well systems often include a pressure tank. The pressure tank helps regulate pressure fluctuations and reduces the frequency of pump cycling. The pressure tank's precharge pressure (the initial pressure at which it is filled) is typically set to 2 psi below the cut-in pressure.
It's important to note that these values are general guidelines, and the specific pressure settings for your well pump system should be based on the manufacturer's recommendations and the requirements of your well system. If you're unsure about the appropriate pressure settings or if you experience issues with water pressure, it's advisable to consult with a professional well pump technician or contact the manufacturer for guidance.
