Buying Guide

  • Determine well depth and required head: If your well depth is substantial, prioritize pumps with higher head ratings (e.g., 270–420+ ft) even if the GPM is moderate.
  • Consider flow vs. lift: For irrigation or pool use, aim for higher GPM; for delivering water at depth, prioritize head height even if GPM is lower.
  • Material and durability: Stainless-steel shells resist corrosion; thermoplastic housing can save weight but may vary in heat tolerance.
  • Power requirements: Heftier HP means more electricity; verify circuit capacity and wiring before installation.
  • Additional features: Built-in check valves and suction screens reduce debris entry and cycling, extending pump life.
  • Installation context: Submersible pumps need appropriate well casing fits; surface pumps require stable mounting and splash protection.

Frequently Asked Questions

  1. What size pump do I need for a deep well? A: For deep wells, prioritize higher head ratings (hundreds of feet) and consider 2 HP or 3 HP models if you need significant GPM at depth.
  2. What is “GPM” and why does it matter? A: GPM stands for gallons per minute and indicates how fast water is delivered; choose based on your water demand.
  3. Can I use a submersible pump for a sump application? A: Yes, but ensure the pump’s design and head capabilities meet your drainage needs and water level height.
  4. Are built-in check valves important? A: Yes, they help prevent rapid cycling and extend pump life by reducing backflow.
  5. Should I choose a stainless-steel shell? A: Stainless steel offers better corrosion resistance, especially in well water with minerals.
  6. Do I need professional wiring for higher HP pumps? A: For 1 HP or higher, it’s prudent to verify electrical requirements and consider professional installation.
