Jet Pump vs Submersible Pump: Which Well Pump Is Better?

Compare jet pumps and submersible well pumps to understand differences in performance, installation, cost, and maintenance. Choose the right pump type for your water system.

How Jet Pumps Work

Jet pumps sit above ground (in a pump house or basement) and create suction to pull water up from the well. Shallow well jets work for depths under 25 feet. Deep well jets use two pipes—one for suction, one for pressure—and can reach 100+ feet, though efficiency drops significantly with depth. Installation is simpler with easy service access.

How Submersible Pumps Work

Submersible pumps install inside the well, underwater, and push water up through a single pipe. The sealed motor and pump assembly sits near the bottom of the well. This design is efficient at any depth, commonly used for wells 25-500+ feet deep. Submersibles are quieter since they're underground but require pulling the pump for service.

Performance and Efficiency Comparison

Depth capability: Submersibles win easily—efficient at any depth vs. jet pumps limited to 100 feet maximum. Efficiency: Submersibles push water up (more efficient); jets pull water (less efficient). Noise: Submersibles are silent; jets can be noisy. Flow rate: Submersibles deliver higher GPM at depth. Service access: Jets are easier to repair but need it more often.

Selecting the Right Pump Type

For wells under 25 feet, either pump type works—jets are simpler and cheaper. For 25-100 feet, submersibles are more efficient but convertible jets work. For wells over 100 feet, submersible pumps are the only practical choice. Most modern installations use submersibles for their efficiency, reliability, and quiet operation.
