Quick Answer
Consider replacing an old shallow well pump with a submersible or jet pump, taking into account the well's depth, yield, and casing size. A new pump with a stainless steel or corrosion-resistant material can improve durability and reduce maintenance. Ensure proper installation and priming to avoid issues.
Choosing the Right Pump Type
When selecting a replacement pump, consider the well’s depth and yield. A submersible pump is suitable for shallow wells (less than 40 feet deep), while a jet pump is better for deeper wells (40-100 feet deep). If you’re unsure, consult a professional to determine the best pump type for your well. Additionally, consider the pump’s flow rate and horsepower to ensure it meets your water demand.
Pump Installation and Priming
Proper installation and priming are crucial for a pump’s longevity. Ensure the pump is installed at the correct depth, and the well casing is properly sized to prevent damage. When priming the pump, use a priming aid or a submersible pump’s manual priming feature to fill the pump’s suction line with water. This will help prevent airlocks and ensure smooth operation.
Material Selection and Maintenance
Select a pump made from durable, corrosion-resistant materials, such as stainless steel or fiberglass. Regular maintenance, including filter cleaning and lubrication, will help extend the pump’s lifespan. Check the pump’s voltage and amperage rating to ensure it matches your power source. Consider installing a pressure switch and pressure tank to regulate water flow and prevent pump overload.
