Quick Answer
A 1/2-inch or 3/4-inch gauge is typically recommended for jet pump installations in shallow wells.
Choosing the Right Gauge Size
When selecting a gauge for a jet pump installation in a shallow well, it’s essential to consider the size of the well, the flow rate, and the pressure requirements. A 1/2-inch gauge is suitable for smaller wells with a flow rate of up to 10 gallons per minute (GPM), while a 3/4-inch gauge is recommended for wells with a flow rate of 10-20 GPM.
Factors to Consider
The gauge size also depends on the pressure requirements of the system. For example, if the pump needs to deliver water to a tank at a height of 50 feet, a 3/4-inch gauge may be required to ensure sufficient flow and pressure. Additionally, the gauge size may need to be sized based on the type of well casing and screen. For instance, a well with a larger casing diameter may require a larger gauge to accommodate the increased flow rate.
Installation Tips
When installing a jet pump with a 1/2-inch or 3/4-inch gauge, it’s crucial to follow proper installation procedures to ensure optimal performance and longevity. This includes ensuring that the gauge is properly sized for the system, that the pump is installed at the correct depth, and that the well casing and screen are properly sealed and aligned. By following these guidelines and selecting the correct gauge size, you can ensure a reliable and efficient jet pump installation in your shallow well.
