Choosing the Right Well Pump

Types of well pumps available

When replacing a well pump, selecting the suitable type is essential. The three most prevalent types include:

Submersible Pumps: Designed to be submerged underwater, these pumps are the most common for deep wells and are efficient and reliable. They are ideal for higher depth applications.
Jet Pumps: Typically used for shallow wells, jet pumps are surface-mounted and draw water using suction. Suitable for depths of approximately 25 feet, they can be less efficient for deeper wells.
Hand Pumps: While less common, hand pumps are still utilized in remote areas or for emergency backup. They are labor-intensive and best for light water supply needs.

How to determine the right size and horsepower

Choosing the correct size and horsepower (HP) for your new well pump is vital to ensure efficient operation. Factors to consider include:

Well Depth: Measure the total depth of your well, as this directly impacts the amount of horsepower needed.
Water Demand: Calculate your household’s water needs to determine the gallons per minute (GPM) flow rate required.
Pressure Requirements: Understand your home’s plumbing system to determine the pressure needed to satisfy all fixtures, which influences the necessary horsepower.

Considerations for energy efficiency

In today’s environmentally-conscious world, selecting an energy-efficient pump can lead to significant cost savings over time. Look for pumps with:

High Efficiency Ratings: Pumps designed with energy efficiency in mind typically feature modern engineering and technology that reduces electricity use.
Variable Speed Drives: These pumps adjust the motor speed to meet demand, saving energy by producing only what is needed.
Good Quality Materials: Investing in durable components can lead to fewer breakdowns, meaning less energy is wasted on repairs.
