Well pumps come in different sizes, depending on your property size, water usage, and the number of plumbing fixtures in your home. They're powered by electric motors that drive impellers or centrifugal pumps to create the necessary pressure for water extraction. When choosing a well pump, the most pivotal factor to ponder is the well depth, which you can determine using a simple string and bobber method.

There are three main types of well pumps: centrifugal pumps, submersible pumps, and jet pumps. Each type is designed for different well depths, with submersible pumps being ideal for deep wells, while jet pumps are better suited for shallow wells. Understanding your well's depth will help you select the most appropriate pump for your water system, ensuring efficient and reliable water supply to your home.

Types of Well Pumps

Now that you understand what well pumps are, let's investigate the different types available. Shallow well pumps, including centrifugal and jet pumps, are suitable for wells up to 25 feet deep. They're accessible above ground for easy maintenance but require priming to function. These pumps typically range from 3/4 to 1 HP and can provide 15-16 gallons per minute.

For deeper wells, submersible pumps are the go-to choice. They're installed underwater at the bottom of the well and can handle depths up to 325 feet. Submersible pumps push water upwards rather than drawing it by suction, with capacities ranging from 1/2 to 1 HP and supplying up to 26 gallons per minute.

Convertible jet pumps offer versatility, operating in both shallow (0-25 feet) and deep (25-90 feet) well configurations. By adjusting the ejector/jet portion, you can increase pressure to draw water from deeper depths.

When selecting a pump, consider well depth, desired capacity, and maintenance requirements. Shallow well pumps are easier to maintain, while submersible pumps require professional service. Your choice will depend on your specific well characteristics and water needs.

Choosing the Right Well Pump

Selecting the right well pump is essential for guaranteeing an efficient and reliable water supply. The primary factor you'll need to ponder is your well's depth. For shallow wells under 25 feet, you'll want to use centrifugal or jet pumps. If your well is deeper than 110 feet, you'll need a submersible pump.

When replacing an existing pump, it's usually best to stick with the same type to maintain compatibility with your current system. Pay attention to the pump's GPM (gallons per minute) and PSI (pounds per square inch) ratings to guarantee it can provide the necessary flow and pressure for your water demand.

Don't make the mistake of oversizing your well pump, as this can lead to reduced performance and energy inefficiencies. Instead, match the pump's capacity to your water needs. If you're replacing an old pump, choose one with the same horsepower to guarantee a proper fit within your well casing.

Well Pump Sizing Guidelines

After considering the various factors in choosing the right well pump, it's important to focus on proper sizing. The size of your well is pivotal in determining the appropriate pump type. For shallow wells less than 25 feet deep, you'll need shallow well jet pumps. Deep well pumps or submersible pumps are necessary for wells between 25-400 feet.

When sizing your well pump system, consider your home's water demand. An average single-family home with 3-4 bedrooms typically requires a pump that can deliver 8-12 gallons per minute. Add 1 GPM for each additional water fixture. It's indispensable not to oversize your pump, as this can lead to reduced performance and energy inefficiency.

If you're replacing an existing pump, choose one with the same horsepower to maintain proper water pressure and flow. However, if you're transporting water over longer distances or to higher elevations, you may need a more powerful pump to overcome friction and vertical lift.

Essential Well Pump Accessories

Well pump systems frequently require additional components to function ideally and protect your water supply. Pressure tanks are indispensable accessories that store water and maintain consistent pressure in your plumbing system when the pump isn't running. They work in tandem with pressure switches, which monitor the pressure in the tank and activate the pump when it drops below a preset level.

To secure a safe connection between your well casing and home plumbing, you'll need a pitless adapter. This device provides a watertight, freeze-proof seal that prevents contamination of your water supply. Check valves are another pivotal component, preventing backflow and ensuring water only flows from the well to your home.

For improved water quality and protection of your plumbing components, you may want to deliberate adding water filters and water softeners to your system. These accessories can remove impurities and reduce mineral buildup in your pipes and appliances.

Installation and Maintenance Tips

With your well pump and accessories selected, it's time to focus on proper installation and ongoing maintenance. You'll need to adhere to local building codes and manufacturer guidelines to guarantee your pump operates efficiently and reliably. Remember, submersible well pumps tend to require professional installation due to their complexity and location deep underground.

For deep well jet pumps or submersible pumps that are more than 25 feet below ground, you'll need to be particularly careful with installation. These pumps create a vacuum in the suction line, which is indispensable for proper water extraction. Shallow well jet pumps, on the other hand, need to be primed regularly to prevent air from entering the system.

To maintain your pump's performance, routinely check the pressure tank, clean the well screen, and inspect for leaks. Replace worn components like the foot valve and impeller as needed. For submersible pumps, it's best to consult a professional well service technician for maintenance and repairs, as they have the specialized equipment and skills required.
