Choosing the right pump for your well water system is a critical decision that impacts water pressure, energy consumption, and long-term costs. The primary choice often comes down to a jet pump or a submersible pump. Submersible pumps are usually the better option for deeper wells, generally those exceeding 25 feet, because they push water up from inside the well, making them more efficient for lifting water over greater distances. In contrast, jet pumps are installed above ground and pull water from the well, making them more suitable for shallower applications. For example, residential water wells are typically 100 to 300 feet deep and 4 to 6 inches in diameter, often favoring the efficiency of submersible pumps for these depths. A well can take about one week to install and, with proper maintenance, can last up to 40 years, making the pump choice a long-term investment.

What Are the Main Types of Well Pumps?

The main types of well pumps used in residential groundwater systems are submersible pumps and jet pumps, each designed for different well depths and operational needs. Submersible pumps operate entirely inside the well, pushing water upwards, while jet pumps are installed above ground and pull water from the well using suction. Understanding these fundamental differences is key to selecting the appropriate pump for your home's water supply.

Submersible Pumps: Operating Below the Surface

Submersible pumps are aptly named because they are designed to be fully submerged in the water within the well. This placement allows them to push water directly up from the water table to your home. Because they operate underwater, they are known for their quiet operation, as the water acts as a natural sound dampener. This design also makes them highly efficient for deeper wells, as they don't have to overcome atmospheric pressure limitations that affect suction-based pumps. For example, Grundfos SQ series submersible pumps are designed for flow rates from 5-25 GPM with heads to 500+ feet, making them suitable for many residential well depths https://scwellservice.com/blog/grundfos-pump-review.html. These pumps often feature advanced technologies like permanent magnet motors, which can deliver significant energy savings. Their construction typically includes durable materials like stainless steel, along with built-in features such as check valves and soft-start motors, which contribute to their longevity and reliable performance. The design of submersible pumps also makes them less susceptible to priming issues compared to jet pumps, as they are always surrounded by water. This constant immersion helps prevent air pockets from forming in the pump, ensuring a consistent water supply. Furthermore, many modern submersible pumps, like those offered by Grundfos, come with integrated protection features, such as automatic dry-run protection, which shuts the pump down if the water level drops too low, preventing burnout and extending the pump's lifespan. The floating impeller design in some models also helps resist damage from sand, which is a common issue in many wells.

Jet Pumps: Working from Above Ground

Jet pumps, in contrast, are installed above ground, typically in a well house or basement. They work by creating a vacuum or suction to pull water from the well. This process involves an impeller that drives water through a narrow nozzle, creating a low-pressure area that draws water up from the well. Jet pumps are generally more suitable for shallower wells, usually those less than 25 feet deep, because their pulling power is limited by atmospheric pressure. As the well depth increases, the efficiency of a jet pump decreases significantly. There are two main types of jet pumps: shallow well jet pumps and deep well jet pumps. Shallow well jet pumps have the nozzle assembly located within the pump housing itself, suitable for very shallow applications. Deep well jet pumps, while still installed above ground, have their ejector assembly (the nozzle and venturi) located down in the well, below the water level. This allows them to pull water from greater depths than a shallow well jet pump, but they still operate on the principle of suction from the surface. While jet pumps are easier to access for maintenance and repairs since they are not submerged, their above-ground operation can result in more noise compared to submersible pumps. They may also require a pressure tank to maintain consistent water pressure in the home and prevent the pump from cycling too frequently. The initial cost of a jet pump can sometimes be lower than a submersible pump, making them an attractive option for homeowners with very shallow wells or specific space constraints. However, their operational efficiency can be a drawback for deeper applications, leading to higher long-term energy costs.

How Deep Is Your Well?

The depth of your well is one of the most important factors in determining whether a jet pump or a submersible pump is right for your home. Residential water wells are typically 100 to 300 feet deep, and their diameter usually ranges from 4 to 6 inches. This depth range generally favors the use of submersible pumps due to their inherent efficiency in pushing water over long vertical distances.

Typical Well Depths and Diameters

Understanding typical well dimensions helps in pump selection. According to data on well drilling costs, residential water wells are typically 100' to 300' deep and 4" to 6" in diameter https://cvfpb.ca.gov/wp-content/uploads/2020/11/8b.-EIS-Attachment-Well-Drilling-Costs.pdf. This means that for the vast majority of homeowners with a private well, a pump designed for deeper applications will be necessary. Wells that fall into the shallower end of this range, perhaps 50-100 feet, might still benefit from a submersible pump, especially if consistent high pressure and energy efficiency are priorities. The diameter of the well casing is also crucial, as it dictates the physical size of the pump that can be installed. Most submersible pumps are designed to fit into standard 4-inch or 6-inch casings. The depth of the well directly impacts the amount of horsepower required for a pump to deliver water to the surface at adequate pressure. A pump lifting water from 200 feet will need more power than one lifting from 50 feet. Choosing an undersized pump for a deep well will result in insufficient water pressure and premature pump wear, while an oversized pump can lead to unnecessary energy consumption and short cycling. Local well drillers or neighbors can often provide insights into typical well depths in a specific area, which can help homeowners estimate their own well's requirements. This local knowledge can be invaluable before drilling or replacing a pump, as geological conditions vary widely and influence well depth.

Impact of Depth on Pump Choice

The physical principle of "suction lift" is what limits jet pumps to shallower depths. A jet pump, operating from the surface, can only effectively pull water up approximately 25 feet due to the limits of atmospheric pressure. Beyond this depth, the pump struggles to create enough vacuum to lift the water efficiently, leading to reduced flow rates and increased energy consumption. For wells deeper than 25 feet, a submersible pump becomes the far more practical and efficient choice. A submersible pump is placed directly in the water column, often near the bottom of the well, and pushes water up using its internal impellers. This "pushing" action is significantly more effective over greater vertical distances than a "pulling" action. For example, Grundfos SQ series pumps can handle heads (the vertical distance water is lifted) up to 500+ feet, far exceeding the capabilities of any jet pump https://scwellservice.com/blog/grundfos-pump-review.html. The deeper the well, the more pronounced the efficiency advantage of a submersible pump becomes. While the initial installation of a submersible pump can be more complex and costly due to the need to lower it into the well, its long-term operational efficiency and reliability for deep wells often outweigh these upfront considerations. Moreover, submersible pumps are less prone to issues like loss of prime, which can occur with jet pumps if air enters the suction line, especially in situations where the water level fluctuates. Therefore, for most residential wells that extend beyond 25 feet, a submersible pump is the recommended and most effective solution, ensuring a consistent and strong water supply to the home.

What Are the Benefits of Submersible Pumps?

Submersible pumps offer several significant advantages for homeowners, particularly for deeper wells, making them a popular choice for residential water systems. Their design allows them to operate directly within the water, leading to quiet performance and superior efficiency.

Quiet Operation and Efficiency

One of the primary benefits of submersible pumps is their quiet operation. Since the pump motor and impellers are submerged deep within the well, the surrounding water acts as a natural sound barrier, muffling any operational noise. This means you won't hear the pump cycling on and off from inside your home or even from outside near the wellhead, providing a much quieter living environment compared to an above-ground jet pump. Beyond quietness, submersible pumps are highly efficient, especially for deeper wells. They push water upwards rather than pulling it, which is a more energy-efficient method for overcoming gravity over long vertical distances. This direct push eliminates the need to overcome atmospheric pressure limitations that restrict jet pumps. For example, Grundfos submersible pumps are known for their engineering excellence and energy efficiency innovations. They pioneered permanent magnet motor technology in submersible pumps, which delivers up to 30% energy savings compared to conventional induction motors https://scwellservice.com/blog/grundfos-pump-review.html. These energy savings can translate into lower electricity bills for homeowners, making the long-term cost of ownership more attractive despite a potentially higher upfront price. The efficiency gain is particularly noticeable in wells that are 100 feet deep or more, where the energy required to lift water becomes substantial. The consistent performance of submersible pumps also ensures a steady water supply and pressure, even under varying demand, which is crucial for modern households with multiple water-using appliances.

Advanced Technology and Durability

Many modern submersible pumps incorporate advanced technologies that enhance their performance, durability, and user convenience. Grundfos, for instance, is a Danish company founded in 1945 and is now the world's largest pump manufacturer, producing 16 million pumps yearly across various applications https://scwellservice.com/blog/grundfos-pump-review.html. Their residential submersible lines, such as the SQ and SQE series, feature stainless steel construction, which provides excellent corrosion resistance and contributes to a longer lifespan. These pumps also include built-in check valves, which prevent water from flowing back down the well, maintaining prime and protecting the pump from water hammer effects. A significant technological advancement is the built-in soft-start motor, which eliminates voltage spikes during startup. These spikes can cause wear and tear on the pump's electrical components and the home's electrical system. The soft-start feature extends the life of both the pump and other electrical equipment. Furthermore, automatic dry-run protection is a standard feature in many Grundfos models. This system automatically shuts the pump down if the water level in the well drops below a safe operating point, preventing the motor from running dry and burning out. This is a critical protection feature that can save homeowners from costly repairs or premature pump replacement. The floating impeller design in these pumps also helps them resist damage from sand and other abrasives that might be present in well water, further enhancing their durability. For even greater control, the SQE series offers constant pressure capability via the CU 301 controller, which maintains steady water pressure from a trickle to full flow, ideal for homes with fluctuating water demands. The GO Remote app allows smartphone monitoring on compatible systems, providing diagnostics and fault history. These combined features contribute to the overall reliability and longevity of submersible pumps, often resulting in a better lifetime value despite their premium pricing.

What Are the Drawbacks of Submersible Pumps?

While submersible pumps offer many advantages, they also come with certain drawbacks that homeowners should consider before installation. These primarily relate to the complexity and cost of installation and repair, as well as potential reliability issues with specific models.

Complex Installation and Repair

One of the main disadvantages of submersible pumps is the complexity and cost associated with their installation and repair. Because these pumps are located deep inside the well, accessing them requires specialized equipment and expertise. Installation involves carefully lowering the pump, motor, electrical wiring, and water pipe into the well casing, often hundreds of feet deep. This process is labor-intensive and typically requires professional well service technicians. If a submersible pump malfunctions, retrieving it from the well for inspection or replacement is a significant undertaking. This often involves pulling up all the piping and wiring, which can be a lengthy and costly process. Unlike a jet pump, which sits above ground and is relatively easy to access for troubleshooting or component replacement, a submersible pump failure can mean a household is without water for an extended period while repairs are being made. The cost of labor for these specialized services can be higher than for an above-ground pump repair. Furthermore, if the pump is dropped during retrieval or installation, it can become lodged in the well, leading to even more complex and expensive recovery operations or potentially requiring the drilling of a new well. These factors contribute to higher overall maintenance and repair costs for submersible pump systems compared to their above-ground counterparts. The need for specialized tools and highly trained technicians also means that do-it-yourself repairs are generally not feasible or recommended for submersible pumps, increasing reliance on professional services.

Reported Reliability Issues with Specific Models

While many submersible pumps are known for their durability and long lifespan, there have been instances of reliability issues with specific models, which can be a significant concern for homeowners. For example, Jonathan Meier of Rain Brothers shared his experience with the Grundfos SBA 3-45-AW automatic cistern pump, noting considerable problems. According to Meier, "In our experience, though, the Grundfos SBA was too much of a gamble in the realm of automatic pumps. While Grundfos has done a great job honoring warranties, the number of warranty claims that we submitted on the SBA model exceeds any other product that we've ever carried." He further elaborated that after about 18-22 months of use, they were seeing far too many pump failures with the Grundfos SBA model. In one particularly troubling instance, as much as 30% of these SBA pumps were defective right out of the box in a single month https://www.rainbrothers.com/grundfos-sba-cistern-pump-review-a-buyer-s-guide?srsltid=AfmBOoppi9bzm3QKvbMVgzkuvP1fZJbgedEsEQCkcZOdBvesUmYWCv3. This led Rain Brothers to stop selling these units due to the high failure rate and a lack of clear communication from Grundfos about the causes and remedies for these issues. Such experiences highlight that even reputable brands can have specific product lines that fall short of expected quality standards. Homeowners should research specific pump models and read reviews before making a purchase, not just rely on brand reputation alone. While Grundfos is generally recognized for engineering excellence and energy efficiency innovations, these reported issues with a particular model underscore the importance of due diligence. A pump failure, especially one right out of the box or within a short period of use, can cause significant inconvenience and unexpected costs, even if warranties are honored. Therefore, it is crucial to balance the benefits of advanced technology and efficiency with potential risks of product reliability, especially for models new to the market.

How Do Jet Pumps Work?

Jet pumps operate above ground, utilizing a unique mechanism to create suction and draw water from a well. They achieve this by using an impeller to create a high-velocity stream of water, which then passes through a specialized nozzle and venturi to generate a low-pressure area that pulls water up from the well. This operational principle makes them distinct from submersible pumps and generally limits their application to shallower water sources.

The Suction Mechanism

The core of a jet pump's operation lies in its suction mechanism, which relies on the principles of fluid dynamics. Inside the pump housing, an electric motor drives an impeller, which rotates rapidly to push water from a small reservoir within the pump casing. This pressurized water is then directed through a constricted nozzle, which dramatically increases its velocity. As this high-velocity jet of water exits the nozzle, it passes into a wider pipe section called a venturi. The sudden expansion into the venturi creates a low-pressure zone, or partial vacuum, around the nozzle. This low-pressure area is what "sucks" water up from the well through the suction pipe. The well water, under the higher atmospheric pressure, is pushed up into this vacuum, mixing with the recirculating water from the pump. This combined flow then continues through the venturi and is discharged into the home's water supply system. A small portion of this discharged water is diverted back to the pump's reservoir to be recirculated through the nozzle, maintaining the continuous jet stream necessary for suction. This recirculation loop is essential for the pump's operation. Because this entire process relies on creating a vacuum to lift water, jet pumps are limited by the physical constraints of atmospheric pressure, meaning they cannot effectively pull water from depths greater than approximately 25 feet. For deeper wells, the energy required to create sufficient vacuum becomes too great, making the pump inefficient or ineffective.

Shallow vs. Deep Well Jet Pumps

While both shallow and deep well jet pumps operate on the same suction principle, their configurations differ to accommodate varying well depths.

Shallow Well Jet Pumps: These pumps are designed for wells where the water level is typically 25 feet or less from the pump's location. In a shallow well jet pump, both the impeller and the jet assembly (nozzle and venturi) are housed together within the pump casing, which sits above ground. Water is drawn directly from the well through a single suction pipe connected to the pump. Because the entire suction mechanism is at the surface, these pumps are most effective for very shallow applications like ponds, cisterns, or wells with a consistently high water table. They are relatively simple to install and maintain, as all components are easily accessible. However, their efficiency drops sharply if the water level fluctuates significantly or if the well is deeper than their practical suction limit. They often require priming, meaning the pump casing and suction line must be filled with water before operation to create the necessary vacuum.

Deep Well Jet Pumps: For wells with water levels between 25 and 100-120 feet, a deep well jet pump might be used. Although the motor and impeller unit remain above ground, the key difference is that the jet assembly (the nozzle and venturi) is separated from the pump housing and lowered down into the well, below the water level. This setup allows the pump to use the "push" of the recirculated water from the surface to create a more powerful low-pressure zone directly at the water source. Water is then pushed up from the jet assembly through a separate discharge pipe to the surface pump, where the main impeller further pressurizes it for household use. This configuration uses two pipes running down the well: one to send pressurized water down to the ejector, and another to bring the well water back up. While more effective for deeper wells than shallow well jet pumps, deep well jet pumps are still less efficient than submersible pumps for depths exceeding 100 feet. They also still require priming of the entire system, including the down-well ejector, which can be more involved than priming a shallow well pump. The added complexity of the two-pipe system and the down-well ejector means installation and maintenance are more involved than for shallow well jet pumps, though still generally simpler than retrieving a fully submerged pump.

What Is the Cost Comparison Between Pump Types and Well Drilling?

Understanding the costs associated with well drilling and pump selection is crucial for homeowners investing in a private water system. The initial investment for drilling a well can be substantial, and the choice between a jet pump and a submersible pump also presents significant cost differences, both upfront and in long-term operation.

Well Drilling Costs

The cost to drill a well varies widely depending on depth, diameter, and casing material. Residential wells are typically 100 to 300 feet deep. For a 100-foot well, the cost can range from $3,550 for a 4-inch PVC casing to $8,400 for an 8-inch steel casing, according to well drilling cost data https://cvfpb.ca.gov/wp-content/uploads/2020/11/8b.-EIS-Attachment-Well-Drilling-Costs.pdf. As the well depth increases, so does the cost. For example, a 200-foot well with a 4-inch PVC casing would cost $7,100, while an 8-inch steel casing at the same depth would be $16,800. A 300-foot well with a 6-inch steel casing would cost $18,360. These figures illustrate that the drilling itself represents a significant portion of the overall investment in a private well system. The choice of casing material also plays a big role; steel casings are generally more expensive than PVC but offer greater durability in certain geological conditions. These prices are for a complete water well system, which usually includes the drilling, casing, and basic pump installation. Local geology can also heavily influence drilling costs. Areas with hard rock may require specialized drilling equipment and more time, driving up expenses. Conversely, areas with softer soil or sand might be less expensive to drill. Homeowners should consult local well drillers for accurate estimates, as regional differences in labor, material costs, and geological conditions are common. A well takes about a week to install and can last up to 40 years with proper maintenance, making the initial drilling cost a long-term investment that provides free water for both residential and irrigation needs.

Pump Purchase and Operating Costs

When comparing pump types, the cost involves not just the purchase price but also installation, energy consumption, and potential repair costs over the pump's lifespan.

Initial Purchase Price: Submersible pumps, especially premium brands like Grundfos, often have a higher upfront cost. Grundfos residential pumps, for instance, run $800-$1,500 for their SQ series and $1,200-$2,500 for the SQE series with its controller https://scwellservice.com/blog/grundfos-pump-review.html. This is typically 30-50% more than comparable Franklin or Sta-Rite pumps. Jet pumps, particularly shallow well models, tend to have a lower initial purchase price, often making them seem more budget-friendly at first glance.

Installation Costs: Installation costs can vary. Submersible pumps require more complex installation due to their placement inside the well, which can increase labor expenses. Jet pumps, being above ground, are generally easier and less costly to install. However, deep well jet pumps still require the ejector assembly to be lowered into the well, adding some complexity.

Energy Consumption and Long-Term Value: The operational cost, primarily electricity usage, is where submersible pumps often demonstrate their long-term value, especially premium models. Grundfos permanent magnet motors deliver up to 30% energy savings compared to conventional induction motors https://scwellservice.com/blog/grundfos-pump-review.html. Southern California Well Service noted, "For most homeowners, yes. The energy savings alone (up to 30% less electricity) can recoup the price difference in 5-8 years. Add the longer lifespan and reduced failure rates, and Grundfos typically provides better lifetime value." These savings can amount to $100-$200 annually in typical use. Over a 15-20 year period, a Grundfos pump might cost less than two cheaper pumps due to its superior efficiency and longer lifespan. Jet pumps, particularly for deeper applications, are generally less energy-efficient because they struggle more to pull water over long distances, leading to higher electricity bills over time.

Maintenance and Repair Costs: As discussed, repairing a submersible pump involves retrieving it from the well, which can be a costly and involved process. Jet pumps, being above ground, are typically easier and less expensive to troubleshoot and repair. However, the overall reliability and lifespan also factor in. While specific models like the Grundfos SBA cistern pump have reported high failure rates https://www.rainbrothers.com/grundfos-sba-cistern-pump-review-a-buyer-s-guide?srsltid=AfmBOoppi9bzm3QKvbMVgzkuvP1fZJbgedEsEQCkcZOdBvesUmYWCv3, many submersible pumps, especially the main well pump lines, are built for longevity. Grundfos pumps often come with a 5-year warranty, matching or exceeding competitors, which provides peace of mind for homeowners. When considering the total cost of ownership, including initial purchase, installation, energy, and potential repairs over the pump's expected lifespan, the long-term value of a highly efficient submersible pump often outweighs its higher upfront cost for most residential deep well applications.

Is Grundfos a Reliable Brand?

Grundfos is widely recognized as a leading manufacturer in the pump industry, known for its extensive product range and commitment to innovation. However, like any large company, specific product lines can sometimes present reliability challenges that are important for consumers to be aware of.

Company Reputation and Innovation

Grundfos is a Danish company, established in 1945, that has grown to become the world's largest pump manufacturer. They boast an impressive annual revenue exceeding $4 billion and produce an astonishing 16 million pumps each year, catering to residential, commercial, and industrial needs globally https://scwellservice.com/blog/grundfos-pump-review.html. Their U.S. headquarters is located in Kansas, supported by manufacturing facilities around the world. The company has built a strong reputation for engineering excellence, consistently pushing boundaries in pump technology. A notable achievement is their pioneering work in permanent magnet motor technology for submersible pumps, which significantly enhances energy efficiency. This innovation allows their pumps to deliver up to 30% energy savings compared to conventional induction motors, positioning them as a premium brand in terms of efficiency and longevity. The SQ and SQE series, their standard residential submersible pumps, feature robust stainless steel construction, built-in check valves, and soft-start motors. These design choices and technological integrations contribute to their high ranking for efficiency and durability in the market. While their pumps command higher prices, typically 30-50% more than comparable Franklin or Sta-Rite pumps, the long-term value proposition is strong. The energy savings alone can recoup the price difference within 5-8 years, and their extended lifespan, often 15-20 years, means they frequently outlast and cost less than multiple cheaper pumps over the same period. This commitment to innovation and quality has solidified Grundfos's position as a leader in the global pump market, making them a go-to choice when energy efficiency, quiet operation, and long-term value are primary considerations.

Specific Product Line Challenges

Despite Grundfos's overall strong reputation, it's important to acknowledge that specific product lines can face challenges. One notable example is the Grundfos SBA 3-45-AW automatic cistern pump, which has raised concerns regarding its reliability. Jonathan Meier, from Rain Brothers, a company that previously carried the SBA model, expressed significant reservations. He stated, "In our experience, though, the Grundfos SBA was too much of a gamble in the realm of automatic pumps. While Grundfos has done a great job honoring warranties, the number of warranty claims that we submitted on the SBA model exceeds any other product that we've ever carried." This indicates a higher-than-average failure rate for this particular model. Meier elaborated that after approximately 18-22 months of use, they observed an excessive number of pump failures. Critically, in one instance, as much as 30% of these SBA pumps were defective right out of the box in a single month https://www.rainbrothers.com/grundfos-sba-cistern-pump-review-a-buyer-s-guide?srsltid=AfmBOoppi9bzm3QKvbMVgzkuvP1fZJbgedEsEQCkcZOdBvesUmYWCv3. This high defect rate, coupled with what Rain Brothers described as a lack of transparency from Grundfos regarding the causes and remedies for these failures, ultimately led them to discontinue selling the SBA units. Customer reviews on platforms like Trustpilot also sometimes reflect issues with specific product parts or customer service experiences, such as difficulties obtaining simple spare parts or pumps failing prematurely outside of warranty periods. For example, one Trustpilot review mentioned a Grundfos shower pump failing after about 15 months of use, just outside its warranty, despite a previous pump lasting 12 years. Another review highlighted the high cost and difficulty in sourcing simple replacement hose connectors. These instances, while not representative of the entire Grundfos product line, underscore the importance for consumers to look beyond general brand reputation and investigate reviews and feedback specific to the exact model they are considering. While Grundfos generally offers a 5-year warranty on residential pumps, matching or exceeding competitors, the inconvenience and potential for repeated issues with a faulty model can be a major drawback.

Frequently Asked Questions

How long does a well pump typically last?

A well pump's lifespan varies based on its type, quality, usage, and maintenance. High-quality submersible pumps, especially those with advanced features like stainless steel construction and soft-start motors, can last 15-20 years, and sometimes even longer. The entire well system, with proper care, can last up to 40 years. Jet pumps may have a slightly shorter lifespan due to their above-ground location and continuous exposure to the elements, but with regular maintenance, they can still provide many years of service.

What is the average cost to drill a well?

The average cost to drill a well depends heavily on its depth, diameter, and casing material. For residential wells typically 100 to 300 feet deep, a 100-foot well with a 4-inch PVC casing costs around $3,550, while a similar 100-foot well with an 8-inch steel casing can cost $8,400. Deeper wells naturally incur higher costs, with a 400-foot well with an 8-inch steel casing costing up to $33,600. These prices generally include the complete water well system.

Can I install a well pump myself?

Installing a well pump, especially a submersible one, is a complex task that typically requires specialized tools and expertise. Submersible pumps need to be carefully lowered into the well, connected to electrical wiring, and properly sealed, making it a job best left to professional well service technicians. Jet pumps, being above ground, are somewhat simpler to install, but still require proper plumbing and electrical connections to ensure safe and efficient operation. Incorrect installation can lead to pump damage, electrical hazards, or inadequate water supply.

What maintenance do well pumps need?

Regular maintenance helps extend the life of your well pump. This includes periodically checking the pressure tank for proper air charge, inspecting electrical connections, and monitoring water pressure and flow rates for any changes.
