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.
