Choosing a jet pump

Choosing a jet pump for a groundwater well requires considering several factors to ensure efficient water delivery. Here's a step-by-step guide:

1. Determine Well Depth

   - Shallow Well (Less than 25 feet deep): A shallow well jet pump is suitable. It uses a single pipe to draw water.

   - Deep Well (25 to 150 feet deep): A deep well jet pump** is needed. It has two pipes—one for suction and one for returning water to the jet assembly.

2. Calculate Water Demand

   - Measure the flow rate in gallons per minute (GPM).

   - A typical home requires 8–12 GPM.

   - Count water-using fixtures and appliances to estimate demand.

3. Check Pump Horsepower (HP)

   - More HP = More water flow and pressure.

   - ½ HP for shallow wells up to 25 feet.

   - ¾ to 1 HP** for deep wells up to 100 feet.

   - 1½ HP or more** for deeper wells.

4. Consider Pressure Requirements

   - Most homes need 30–50 PSI.

   - Choose a pump that meets the required pressure range.

5. Look for Quality and Efficiency

   - Opt for corrosion-resistant materials (cast iron, stainless steel, or thermoplastic).

   - Energy-efficient pumps save electricity in the long run.

6. Check Compatibility with a Pressure Tank

   - A pressure tank prevents frequent pump cycling.

   - Ensure the pump works with your tank size and pressure settings.

7. Consider Additional Features

   - Self-priming pumps for easy startup.

   - Thermal overload protection to prevent overheating.

   - Noise levels if the pump is near living spaces.
