Quick Answer
Low water pressure in jet pumps often stems from clogged or air-entrained suction lines, insufficient submergence, or malfunctioning check valves, which can be resolved through regular maintenance and system adjustments.
Identifying the Source of Low Pressure
Check the suction line for debris, sediment, or air pockets by inspecting it visually or using a submersible pump with a built-in check valve to isolate the issue. Remove any visible blockages or install a check valve to prevent air from entering the system. Ensure the suction line is properly connected to the pump and the well’s water level is at least 10 feet below the pump’s intake for adequate submergence.
Adjusting the Pump’s Performance
Adjust the pump’s stroke length or speed to optimize its performance for the specific well’s water level and flow characteristics. Typically, a 2-inch stroke length is suitable for shallow wells, while a 1.5-inch stroke may be more effective for deeper wells. Be cautious when adjusting the stroke length, as excessive length can lead to over-pumping and decreased efficiency.
System Maintenance and Upgrades
Regularly flush the suction line with a high-pressure hose to remove any accumulated sediment or debris, which can clog the line and reduce water pressure. Consider upgrading to a more efficient pump, such as a submersible or a solar-powered jet pump, if the existing pump is outdated or underperforming. Regularly inspect and maintain the entire system to prevent damage and ensure reliable operation.
