How Deep Can a Well Pump Pull Water? Understanding Suction Lift Limits

Discover the maximum depth a well pump can efficiently pull water and learn about submersible pumps for deeper wells.

56 views

The depth from which a well pump can pull water, known as suction lift, typically maxes out at about 25 feet (7.6 meters) due to atmospheric pressure limits. For wells deeper than this, submersible pumps are installed within the well itself, capable of pushing water up from depths of several hundred feet, ensuring a reliable water supply even from deep underground sources.

FAQs & Answers

  1. What is the maximum depth a well pump can pull water from? A well pump can typically pull water from a maximum depth of about 25 feet (7.6 meters) due to atmospheric pressure limits.
  2. What type of pump is used for deeper wells? For wells deeper than 25 feet, submersible pumps are used, as they are installed within the well and can push water up from several hundred feet.
  3. Why can't a standard well pump pull water from more than 25 feet? Standard well pumps are limited by atmospheric pressure, which can effectively lift water up to approximately 25 feet; beyond this depth, suction lifts become ineffective.
  4. How do submersible pumps work? Submersible pumps work by being submerged in water and using a motor to pump water upwards, allowing for extraction from significant depths.
