Quick Answer
If your pump is losing pressure, first check the intake suction line for blockages or kinks, and ensure the well casing and surrounding soil aren't causing restrictions. Next, inspect the pump's impeller for damage or wear, and replace it if necessary. Consider consulting a professional if the issue persists.
Troubleshooting Steps
When dealing with a losing-pressure pump, it’s essential to methodically check the system for any potential issues. Start by inspecting the intake suction line for any blockages or kinks that could be restricting water flow. A partially blocked intake line can significantly reduce the pump’s suction capacity, leading to low pressure. Use a water pressure test gauge to measure the static pressure at the pump intake, and compare it to the recommended range for your pump.
Pump Impeller Inspection and Replacement
Inspecting the pump’s impeller is another crucial step in identifying the cause of low pressure. A damaged or worn-out impeller can’t effectively push water through the system, resulting in reduced pressure. Remove the pump casing and inspect the impeller for any signs of damage or wear. Replace the impeller with a new one if necessary, ensuring it’s properly aligned and secured to the pump shaft.
Common Causes and Solutions
In many cases, losing-pressure pumps are caused by issues with the well casing or surrounding soil. Check the well casing for any blockages, such as sediment or debris, and clean it out if necessary. Additionally, ensure the well casing is properly sloped to allow for easy water flow. If the surrounding soil is causing restrictions, consider installing a well screen or gravel pack to improve water flow into the well.
