Submersible Pump vs Jet Pump: Which Is Right for Your Tucson Well Pump Installation?

Fri, 23 Oct 2026 11:32:56 GMT

Choosing the right well pump is one of the most practical decisions a Tucson-area homeowner can make, and knowing how each pump type works can save time, money, and frustration. Homeowners searching for a well pump installation contractor in Tucson, AZ, often face the same core question: sub mersible pump or jet pump? This article breaks down both options in plain language so you can have a more informed conversation with a well pump installation contractor before any work begins.

How Each Pump Type Actually Works

Submersible pumps live entirely inside the well casing, submerged in the water. They push water upward to the surface using a sealed motor that runs underwater. Because the motor stays cool from the surrounding water, these units tend to run efficiently even during Southern Arizona's intense summer heat.

Jet pumps work very differently. The motor sits above ground and pulls water up using suction. A shallow-well jet pump can handle depths up to about 25 feet. A deep-well jet pump can reach somewhat deeper, but still has practical limits that often make it a poor match for most Southern Arizona properties.

Why Well Depth Matters Most in the Tucson Area

Tucson, AZ, sits within the Sonoran Desert's basin-and-range geology. That means water tables are naturally deep. Wells in Pima County and the surrounding region commonly run 200 to 600 feet deep. At those depths, a jet pump simply cannot generate enough suction to lift water reliably to the surface.

Submersible pumps handle deep wells without difficulty. They are the standard choice across Tucson, Marana, Green Valley, Sahuarita, and other Southern Arizona communities for exactly this reason. A jet pump may work on a shallow well in a wetter region, but it is rarely the right fit for properties where depth is a factor.

If you are unsure how deep your well runs, a licensed well pump installation contractor can measure static water level and help you determine which system matches your site.

Energy Efficiency in Arizona's Heat

Arizona summers push ambient temperatures well above 100 degrees. Above-ground equipment, including jet pump motors, can run hotter and work harder under those conditions. Submersible pumps stay cooler because they operate below the water surface, which may help extend motor life in a harsh climate like Southern Arizona.
That said, pump efficiency also depends on proper sizing. An oversized or undersized pump will cycle incorrectly and wear out faster regardless of type. A proper site assessment from a qualified well pump installation contractor ensures the pump chosen is matched to your actual flow rate and pressure needs.

Lifespan and Maintenance Differences

Submersible pumps are generally built to last many years with relatively low maintenance. Because they operate in a sealed, protected environment inside the casing, they are shielded from dust, debris, and extreme surface temperatures. The main trade-off is accessibility: if a submersible pump needs repair, it must be pulled from the well, which requires professional equipment. Jet pumps are easier to access since the motor sits above ground. A technician can inspect or service the motor without pulling anything from the well. However, jet pumps can lose their prime (the water needed to create suction), which may require attention after a power outage or pressure drop.

For most Tucson-area homeowners with deep wells, the submersible pump's durability and sealed design often outweigh the easier access of a jet pump.

What Happens If a Submersible Pump Fails?

When a submersible pump fails, water flow to the home stops. Common signs include a sudden loss of pressure, sputtering faucets, or the pump running constantly without delivering water. Prompt service can prevent the problem from affecting your pressure tank or other system components. Learn more about signs your well pump may need replacement .

Can a Jet Pump Work in Tucson?

A jet pump may work on a very shallow well, but shallow wells are uncommon in the Tucson, AZ, area given the region's deep water table. For most residential properties here, a submersible pump is the more practical and reliable option. Always have a well pump installation contractor assess your specific well before selecting any pump system.

How Do I Know Which Pump I Currently Have?

If your pump motor is visible near the pressure tank inside a garage or pump house, you likely have a jet pump. If there is no visible motor near the tank and the system is quieter during operation, you most likely have a submersible pump. A licensed technician can confirm this during an inspection.

Making the Right Call for Your Property

For the majority of homeowners in the Tucson, AZ, area, a submersible pump is the better fit. Deep water tables, extreme heat, and the need for consistent pressure all point in that direction. Jet pumps may suit a narrow set of properties with shallow wells, but those situations are less common in Southern Arizona. The most reliable way to choose is to have a professional evaluate your well depth, casing size, and household water demand before making any decisions.

What to Expect When Drilling a New Water Well in Tucson: A Step-by-Step Guide for 2026

Thu, 22 Oct 2026 19:05:10 GMT

Drilling a new water well in the Tucson, AZ, area involves several regulated steps every property owner should understand before work begins. This guide walks through each phase, from site assessment to final water testing, so you know what to expect when you invest in well drilling services. Whether your property is in the Catalina Foothills, Vail, Marana, or unincorporated Pima County, the process follows a consistent path governed by state and local rules.

Why Tucson's Geology Makes Well Planning So Important

The Tucson basin sits on a deep alluvial aquifer fed by theSanta Cruz River and surrounding mountain ranges. Many properties in centraland west Tucson reach reliable water at 250 to 350 feet, but conditions vary.Properties near the Catalina Foothills or Oro Valley may require 300 to 450feet of drilling, and caliche layers are common throughout the basin and canslow progress.

Pima County falls within the Tucson Active Management Area (AMA), where ADWR regulates groundwater use. Understanding this upfront helpsyou plan realistic timelines and budget accordingly.

Step 1: Site Assessment and Feasibility Check

Your licensed driller will review your parcel, evaluate local well logs from nearby properties, and confirm your land is suitable for installation. They will also check setback requirements, including required separation between your well and any on-site septic system.

Before drilling, you must obtain authorization from ADWR and file information describing how the well will be constructed. Most single-family residential wells qualify as exempt domestic wells, which carry a simpler permit pathway. Choosing experienced well drilling services at this stage ensures the site assessment is thorough and the permit application is filed correctly.

Step 2: Filing the ADWR Notice of Intent

The permit process is non-negotiable for well drilling services in Tucson, AZ. Prior to drilling, deepening, or modifying a well, you must file a Notice of Intent to Drill with ADWR along with the appropriate fee.

ADWR typically reviews the Notice of Intent within 15 days, though county review can add one to two additional weeks. Plan for a total pre-drilling wait of three to six weeks in most straightforward cases.

Before work begins, confirm that your driller is licensed. All well drillers must be licensed by both ADWR and the State Registrar of Contractors (ROC), which protects you legally and ensures the work is recognized by the state.

Step 3: Drilling Day: What Actually Happens on Your Property

A large drilling rig will be set up on your property and the crew will begin boring using rotary or air-rotary equipment suited to local geology. Drilling typically takes one to three days depending on depth and conditions. Tucson-area drillers frequently encounter caliche layers that require additional bit time.

Once the target depth is reached and water-bearing zones are confirmed, the driller sets steel or PVC casing inside the borehole to stabilize the walls and protect against surface contamination. A cement or bentonite grout seal is then applied around the casing near the surface.

Proper well construction standards help prevent contamination of the well and surrounding aquifer. Professional well drilling services use grout application techniques that meet ADWR construction standards for long-term aquifer protection.

Step 4: Pump Installation and System Setup

Pump and pressure tank installation typically takes about one day after drilling is complete. A submersible pump is lowered to the appropriate depth, and a pressure tank and control system are installed at the wellhead.

Pump size is matched to your water demand and the well's yield capacity. You can learn more about this phase on the well pump installation contractor page.

Step 5: Water Testing and Final Inspection

Water testing is a critical step that should never be skipped. Lab turnaround typically takes one to two weeks. Tests commonly check for bacteria, nitrates, and other contaminants relevant to the Tucson basin. Some properties show arsenic or hardness issues depending on the sub-basin.

Once testing confirms the water meets safe drinking standards, final plumbing and electrical connections are completed, and a final inspection closes out the permit process with ADWR and your local jurisdiction.

Signs Your Well Pump Needs Replacement: A Well Pump Installation Guide for Tucson Property Owners

Mon, 03 Aug 2026 15:13:49 GMT

Knowing when your well pump needs to be replaced can save you from a sudden loss of water at your property in Tucson, AZ. This guide covers the most common warning signs, explains why desert conditions accelerate pump wear, and walks you through when to call a well pump installation contractor.

Warning Signs Your Well Pump May Be Failing

A failing well pump often signals trouble before it stops working completely. Watch for these signs on your Southern Arizona property.

• Low or inconsistent water pressure. Weak flow at faucets or showerheads is often the first thing homeowners notice. If pressure drops suddenly or varies throughout the day, the pump motor or impeller may be struggling.

• Pump cycles on and off repeatedly. Short-cycling means the pump turns on and off far more often than normal, pointing to a failing pressure tank, a worn pump, or both.

• Air spitting from faucets. Bursts of air before water flows can mean the pump is drawing air instead of water, which happens when it sits near the bottom of a dropping water table.

• High electric bills. A pump working harder than it should draws more electricity. If your power bill climbs without another obvious cause, an inefficient pump may be responsible.

• Discolored or gritty water. Sandy, silty, or rust-colored water suggests the pump intake screen may be failing or the pump itself is deteriorating, a common problem in Tucson's caliche-heavy soils.

• Pump age over 10 to 15 years. Most submersible pumps last 10 to 15 years under normal conditions. Tucson-area wells typically run 200 to 1,400 feet deep, and pushing water that far adds strain that can shorten pump life.

Why Tucson's Climate Can Be Harder on Well Pumps

Tucson's desert environment creates specific stress for submersible pump systems. Summer temperatures regularly exceed 100 degrees Fahrenheit, raising operating temperatures inside the wellbore. Higher mineral content in Southern Arizona groundwater causes scale buildup on pump components over time. Properties in the Avra Valley or Altar Valley may also deal with higher sediment loads during monsoon season, increasing wear on impellers and seals. Scheduling an evaluation with a well pump installation contractor before monsoon season helps you stay ahead of these stressors.

How Long Do Well Pumps Typically Last?

Most residential well pumps last 10 to 15 years, though Tucson-area conditions may shorten that range. Deeper wells require the motor to work harder on every cycle, adding wear over time.

Can I Repair My Pump Instead of Replacing It?

Repairs may work for minor issues like a failing pressure switch or worn seal. If the motor has burned out or the pump body is corroded, a full replacement is typically the more reliable long-term option. A well pump installation contractor can inspect the system and give you an honest recommendation based on age, condition, and depth.

What Happens If I Ignore a Failing Pump?

Ignoring the warning signs can result in complete pump failure, damage to the drop pipe and wiring inside the well, and loss of water service. Acting early reduces the total scope of work needed.
