Guide to 2-line jet pumps on water wells: this article describes the components of a two-line jet pump water system, what the components look like, and what they do. We discuss how two-line jet pumps are selected, installed, jet pump troubleshooting, & repair procedures.

This article series describes various types of drinking water sources like wells, cisterns, dug wells, drilled wells, artesian wells and well and water pump equipment. We provide advice about what to do when things go wrong.
Readers of this document should also see our other diagnostic guides for water pumps, wells, motors, in table form:
See Water Tank Types and before assuming that a water problem is due to the well itself, see Water pump and pressure tank repair diagnosis & cost which offers an example of diagnosis of loss of water pressure, loss of water, and analyzes the actual repair cost. If your building has water pressure problems, see WELL WATER PRESSURE DIAGNOSIS. Readers whose wells simply run out of water should also see How to Test Well Water Quantity and see How to Get More Water From a Well.
A two-line jet pump can typically raise water from depths of 30-feet to 80-feet, and at water delivery rates of 4 gpm (gallons per minute) (for a 1/2 hp 2-line jet pump serving an 80 foot deep well) to 16 gpm (for a 1 hp 2-line jet pump serving a 30 foot deep well). At WATER PUMP CAPACITIES TYPES RATES GPM we compare the pumping capacities of one line jet pumps, two line jet pumps, submersible well pumps, and other water pumping methods.
A nice example table of Deep Well 2-Line Jet Pump Capacities for 1/2 hp and 1 hp deep well pumps is provided in the Water Ace Jet Pump Installation Manual and excerpted below to illustrate the factors that determine well pump capacity. Both of the charts below are for 2-line jet pumps produced by Water Ace. 2-Line jet pumps intended for deep well use and made by other manufacturers can be expected to have similar capacities.
The Water Ace charts (shown in part above) make clear that the capacity of a deep well pump to deliver water at a given flow rate varies by these factors:

Watch out: Safety warnings are throughout any pump manufacturer's instructions. Because some pump models are capable of developing internal pressures of more than 100 psi, if your building piping, pressure relief valves, safety controls, wiring, and plumbing are not properly installed, very dangerous conditions including electrical shock, tank explosion, and leaks or floods can occur.
The following list and definition of two-line deep well jet pump and water well parts and terms is organized from the top of the drawing towards its bottom and uses names that correspond to those shown in our ugly sketch above.

Some of the well pump troubleshooting suggestions in this list can be found at the Betta-Flo Jet Pump Installation Manual from the National Pump Co.
