Constant Well Pump? 5 Fixes to Save Water & Money Now!

Is Your Well Pump Running Non-Stop? Here’s How to Fix It!

Are you staring at an inexplicably high water bill? Do you hear the persistent hum of your well pump, even when no one is using water? If so, you’re not alone. A constantly running well pump is a common homeowner problem that can quickly escalate into a costly nightmare.

The Frustration and the Expense

Imagine this: You receive your monthly water bill, and the amount is shockingly high, far exceeding your typical usage. You investigate and discover your well pump is constantly running, struggling to maintain pressure. This constant operation isn’t just annoying; it’s a drain on your electricity, a waste of precious water, and can lead to premature failure of your well pump system.

The financial implications of a continuously running well pump can be substantial. Beyond the inflated water bill, the pump itself is working overtime, increasing the likelihood of expensive repairs or even a complete replacement.

Identifying the Culprits

The good news is that a constantly running well pump is often a symptom of an underlying issue that can be diagnosed and fixed. The most common causes typically fall into five categories:

• A faulty pressure switch.
• A leaky pressure tank.
• Hidden water leaks in your plumbing.
• A failing check valve or foot valve.
• Issues with the well pump itself.

Taking Control: Saving Water and Money

By understanding these potential causes and taking proactive steps to diagnose and address the problem, you can save a significant amount of water, reduce your electricity bill, and extend the life of your well pump system. In many cases, the fix may be simpler than you think.

The key is to approach the problem systematically, ruling out potential causes one by one. While some repairs may require the expertise of a qualified plumber, many troubleshooting steps can be performed by the average homeowner. Let’s dive into each of these common causes, starting with the most likely offender: the pressure switch.

Understanding Your Well Pump System: A Quick Overview

Before diving into the potential culprits behind a relentlessly running well pump, it’s crucial to grasp the fundamental workings of the system itself. Understanding the components and their intended functions provides a solid foundation for troubleshooting and diagnosis. A typical residential well water system comprises several key elements working in concert to deliver water to your home.

Core Components of a Well Water System

Let’s examine these components individually.

• Well Pump: The heart of the system, the well pump, is responsible for drawing water from the well and pushing it into your home’s plumbing. These are typically submersible pumps (located within the well) or jet pumps (located above ground).

• Pressure Tank: This tank stores water under pressure, providing an immediate supply when you turn on a faucet or appliance. Crucially, it prevents the pump from cycling on and off every time a small amount of water is needed.

• Pressure Switch: This is the brain of the operation. The pressure switch monitors the water pressure within the tank. When the pressure drops below a set threshold, it signals the pump to turn on. Once the pressure reaches the upper limit, the switch tells the pump to shut off.

• Check Valve: This one-way valve is designed to prevent backflow. Located either near the pump or at the point where the water line enters the pressure tank, it ensures that water flows only one way: from the well to the tank.

• Plumbing Lines: A network of pipes connects all these components, transporting water from the well, through the pressure tank, and into your home’s plumbing system.

The Intended Operation: A Symphony of Function

In a properly functioning system, the well pump draws water from the well and fills the pressure tank. The pressure switch continuously monitors the pressure inside the tank.

As water is used in the house, the pressure in the tank gradually decreases. When the pressure drops to a predetermined "cut-in" point (e.g., 40 psi), the pressure switch activates the well pump.

The pump then runs until the pressure reaches the "cut-out" point (e.g., 60 psi). At this point, the pressure switch shuts off the pump.

The pressure tank now contains a reservoir of pressurized water ready to supply your household needs. This cycle repeats as water is used, maintaining a consistent water pressure without excessive pump cycling. This smooth and controlled process is what should be happening. Deviations from this ideal operation are often the key to diagnosing problems.

Problem #1: Faulty Pressure Switch – Is This Your Culprit?

Now that you have a grasp of how the well pump system operates, it’s time to investigate potential causes for its constant operation. One of the most frequent offenders is a malfunctioning pressure switch.

This seemingly small component plays a pivotal role in regulating the entire system, and when it falters, it can lead to significant problems.

Understanding the Pressure Switch’s Role

As mentioned earlier, the pressure switch acts as the brain of your well pump system. Its primary function is to monitor the water pressure within the pressure tank.

When the pressure drops below a pre-set "cut-in" point (typically around 40 PSI), the switch activates the well pump, signaling it to refill the tank. Once the pressure reaches the "cut-out" point (usually around 60 PSI), the switch is supposed to shut off the pump.

A faulty pressure switch can fail to properly signal the pump to turn off, even when the pressure tank is full. This results in the pump running continuously, needlessly consuming electricity and potentially damaging the pump itself.

Identifying the Symptoms

The most obvious symptom of a faulty pressure switch is a well pump that runs constantly, even when no water is being used in the house.

You might also notice that the water pressure is excessively high, or that the pressure gauge on the system reads beyond the normal operating range. In some cases, you might hear the pump cycling rapidly, turning on and off in short bursts, before eventually settling into a continuous run.

Diagnosing the Issue

Before condemning the pressure switch, it’s wise to perform a few simple checks to rule out other potential issues like general power problems.

1. Visual Inspection: Begin by visually inspecting the pressure switch for any obvious signs of damage, such as cracks, corrosion, or loose wiring.

2. Check for Blockages: Ensure that the small tube connecting the switch to the plumbing line is clear of debris. This tube can become clogged with sediment or mineral deposits, preventing the switch from accurately sensing the water pressure.

3. Tap Test: With the pump running, gently tap on the pressure switch housing. Sometimes, this can dislodge a stuck contact and cause the switch to function momentarily. If the pump shuts off after tapping, it’s a strong indication that the switch is faulty.

4. Multimeter Test (Advanced): If you are comfortable working with electricity, you can use a multimeter to test the continuity of the switch’s contacts. With the pump running, disconnect the power to the switch. Using the multimeter, check for continuity across the contacts. If there is no continuity when the tank is full, the switch is likely faulty.

Safety First: Always disconnect power to the well pump system before performing any electrical testing. If you are not comfortable working with electricity, consult a qualified electrician or plumber.*

The Solution: Replacing the Pressure Switch

If your diagnosis points to a faulty pressure switch, replacement is usually the most effective solution.

The process is relatively straightforward:

1. Disconnect Power: Turn off the power to the well pump system at the circuit breaker.

2. Drain Pressure: Open a faucet in the house to relieve the pressure in the system.

3. Disconnect Wiring: Carefully disconnect the wires from the old pressure switch, noting their positions for easy reconnection.

4. Remove Old Switch: Unscrew the old pressure switch from the plumbing fitting.

5. Install New Switch: Apply Teflon tape to the threads of the new pressure switch and screw it into the fitting.

6. Reconnect Wiring: Reconnect the wires to the new pressure switch, matching the positions you noted earlier.

7. Restore Power: Turn the power back on at the circuit breaker.

8. Monitor: Observe the system to ensure that the pump cycles on and off correctly and that the pressure stays within the normal operating range.

Replacing a faulty pressure switch is a relatively inexpensive and straightforward repair that can save you money on your water bill and prevent further damage to your well pump.

Problem #2: Leaky Pressure Tank – Are You Losing Pressure?

Having explored the potential issues with the pressure switch, let’s delve into another common culprit behind a constantly running well pump: the pressure tank itself. A compromised pressure tank can wreak havoc on your system, leading to a frustrating cycle of problems and potentially costly repairs.

Understanding the Pressure Tank’s Function

The pressure tank is a critical component in your well system. It’s designed to store a volume of pressurized water, providing on-demand supply when you open a faucet or flush a toilet. More importantly, it minimizes the frequency with which the well pump needs to turn on and off.

Inside the tank, there’s typically an air bladder or a pre-charged air cushion. This air cushion compresses as water is pumped into the tank, maintaining pressure.

When you use water, the air pressure pushes the water out of the tank. This reduces the need to have the well pump start every time a small amount of water is required.

How Leaks Affect Pump Operation

A leak in the pressure tank, whether it’s a physical breach in the tank itself or a loss of air charge in the bladder, undermines its ability to maintain pressure.

As a result, the water pressure drops rapidly, forcing the well pump to cycle on and off more frequently—a phenomenon known as short cycling.

In severe cases, the pump may even run continuously in an attempt to compensate for the pressure loss.

Recognizing the Symptoms of a Leaky Tank

Several telltale signs can indicate a problem with your pressure tank.

• Short Cycling: This is the most common symptom. You’ll notice the well pump turning on and off frequently, even when water usage is minimal.

• Waterlogged Tank: A tank is waterlogged when the air bladder has failed or lost its charge. The tank becomes filled with water and offers little to no pressure. You can often tell this by tapping on the side of the tank – a full tank will sound solid.

• Fluctuating Water Pressure: Inconsistent water pressure throughout your home can also suggest a failing pressure tank.

Diagnosing the Issue

Pinpointing the problem requires a bit of investigation.

1. Inspect for External Leaks: Carefully examine the tank’s exterior for any signs of water leakage, rust, or corrosion.
2. Check the Air Charge: Locate the Schrader valve (similar to a tire valve) on the top of the tank, usually covered by a plastic cap. Use a tire pressure gauge to check the air pressure. The pressure should be a couple of PSI below the cut-in pressure of your pressure switch, typically around 38 PSI.
3. Perform the "Tap Test": As described earlier, tap on the side of the tank. A solid sound indicates the tank is likely waterlogged.

Solutions: Recharge or Replace

Depending on the diagnosis, you have two primary options.

• Recharging the Tank: If the air charge is low, you can attempt to recharge the tank using an air compressor. Always depressurize the tank completely before adding air. Follow the manufacturer’s instructions for the proper air pressure setting.

• Replacing the Tank: If the tank is physically damaged, severely corroded, or the air bladder has completely failed, replacement is the only viable option. Consider consulting with a qualified plumber to ensure proper installation and sizing of the new tank. A correctly sized tank can greatly increase the lifespan of your pump.

Having explored the potential issues with the pressure switch, let’s delve into another common culprit behind a constantly running well pump: the pressure tank itself. A compromised pressure tank can wreak havoc on your system, leading to a frustrating cycle of problems and potentially costly repairs.

Now, let’s shift our attention to a less obvious, yet equally significant cause: hidden water leaks. These silent offenders can drive your well pump to exhaustion and inflate your water bill without you even realizing it.

Problem #3: Hidden Water Leaks – Are You Wasting Water Unknowingly?

While a faulty pressure switch or a compromised pressure tank presents itself with noticeable symptoms, hidden water leaks often operate in the shadows, silently draining your resources and overworking your well pump. Even seemingly insignificant leaks, when accumulated over time, can place a substantial demand on your well system, leading to its continuous operation.

The Silent Drain: How Leaks Impact Your Well Pump

The fundamental principle at play here is simple: your well pump is designed to maintain a certain water pressure in your plumbing system. Any loss of pressure, even a slow and steady one caused by a small leak, triggers the pump to activate and replenish the lost water.

Imagine a slow drip from a faucet: each drop may seem negligible, but multiplied over hours, days, and weeks, it translates into a significant volume of water wasted. This constant demand forces your well pump to run more frequently than it should, attempting to compensate for the ongoing pressure loss.

Spotting the Signs: Recognizing the Symptoms of Hidden Leaks

Detecting hidden water leaks requires a keen eye and a proactive approach. Unlike a burst pipe that announces itself with a dramatic flood, these leaks often present with subtle, easily overlooked symptoms.

• Unusually High Water Bill: This is often the first and most telling indicator. If your water bill has inexplicably spiked without any changes in your water usage habits, a hidden leak is a prime suspect.

• Damp Spots or Mold Growth: Keep an eye out for damp areas in your yard, basement, or crawl space. These spots could indicate a leak in underground pipes or within your home’s structure. Mold or mildew growth in unusual places can also signal hidden moisture problems.

• Dripping Faucets and Running Toilets: These are the most obvious, but also the most frequently ignored. A constantly dripping faucet or a toilet that runs intermittently can waste a surprising amount of water over time. Don’t dismiss these minor issues – address them promptly.

Diagnosis: Uncovering the Source of the Leak

Finding the source of a hidden water leak can be a challenging task, often requiring a process of elimination and careful observation.

• Inspect Your Fixtures: Start by thoroughly inspecting all your faucets, showers, and toilets for any signs of leaks. Pay close attention to the seals around faucets and the flapper valve in your toilet tank. Add food coloring to the toilet tank and see if the color appears in the bowl. This indicates a leak in the flapper valve.

• Check Underground Plumbing: This can be more difficult. Look for unusually wet areas in your yard, particularly near your well pump or water lines. You might also notice a drop in water pressure when multiple fixtures are in use. If you suspect an underground leak, consider calling a professional plumber with leak detection equipment.

• Monitor Your Water Meter: Turn off all water-using appliances and fixtures in your home. Then, check your water meter. If the meter is still running, even slowly, it indicates a leak somewhere in your system.

The Solution: Repairing and Preventing Leaks

Once you’ve identified the source of the leak, the next step is to repair it promptly.

• DIY Repairs: Minor leaks, such as dripping faucets or faulty toilet flappers, can often be fixed with simple DIY repairs. Replacement parts are readily available at most hardware stores.

• Professional Plumbing Services: For more complex leaks, such as those located in underground pipes or within walls, it’s best to call a qualified plumber. They have the expertise and equipment necessary to accurately locate and repair these leaks without causing further damage.

• Proactive Prevention: Regularly inspect your plumbing fixtures and address any minor issues before they escalate into major leaks. Consider installing water leak detectors to alert you to potential problems early on. These detectors can save you significant amounts of money and prevent extensive water damage.

While pinpointing those hidden leaks can feel like detective work, sometimes the issue lies deeper within your well system itself. A crucial component often overlooked is the check valve and foot valve. When these fail, they can lead to a frustrating problem: water flowing backward, causing your pump to work overtime and potentially run non-stop.

Problem #4: Failing Check Valve or Foot Valve – Is Water Flowing Backwards?

The unsung heroes of your well system are the check valve and the foot valve. They ensure water flows in one direction only – up from the well and into your home. When these valves falter, the consequences can be significant.

The Role of Check Valves and Foot Valves

Understanding the function of these valves is key to diagnosing pump problems.

• Check Valve: Typically located near the pump or pressure tank, the check valve prevents water from flowing back down the plumbing and towards the well. It’s a one-way gate, opening to allow water to flow upwards into the pressure tank and closing to prevent backflow when the pump shuts off.

• Foot Valve: Found at the bottom of the suction pipe inside the well, the foot valve serves two primary purposes. Firstly, it acts as a check valve, preventing water from draining out of the pipe and back into the well when the pump is not running. Secondly, it helps maintain the prime of the pump, ensuring it’s always full of water and ready to operate.

When Valves Fail: The Backflow Problem

A faulty check valve or foot valve creates a significant problem: backflow. When either valve fails to seal properly, water can flow back down the well.

This reverse flow causes several issues. The pressure in the system drops rapidly, triggering the pump to restart frequently, a phenomenon known as short cycling. In severe cases, the pump may run continuously, attempting to maintain pressure against the constant backflow.

Furthermore, a failing foot valve can lead to a loss of prime. The pump loses its water supply, resulting in reduced water pressure or even the inability to pump water at all. The pump will struggle, running continuously and potentially overheating as it tries to draw water that isn’t there.

Symptoms of a Failing Valve

Recognizing the symptoms of a failing check valve or foot valve is crucial for timely diagnosis and repair. Here are some telltale signs:

• Frequent Pump Cycling: The pump turns on and off more often than usual, even when water usage is minimal.

• Loss of Prime: The pump struggles to draw water, resulting in sputtering faucets or complete loss of water pressure. You might hear the pump running, but no water is being delivered.

• Reduced Water Pressure: Overall water pressure throughout your home is noticeably lower than usual.

Diagnosing the Problem

Testing a check valve can be a bit tricky, but here’s a simplified method.

1. Isolate the System: Turn off the power to the pump and close the main shut-off valve to your house. This will isolate the pressure tank and pump from your home’s plumbing.

2. Monitor Pressure: Observe the pressure gauge on the pressure tank. If the pressure drops rapidly even though no water is being used, it could indicate a faulty check valve allowing backflow.

3. Listen for Backflow: With the pump off, carefully open a faucet. If you hear air sputtering or gurgling noises, it could be a sign that water is flowing back down the well.

Note: Diagnosing a foot valve requires pulling the pump out of the well, which is often best left to a professional.

The Solution: Replacement

Unfortunately, repairing a check valve or foot valve is rarely a viable option. The most reliable solution is to replace the faulty valve.

This involves:

1. Shutting off the power to the pump.

2. Draining the system.

3. Disconnecting the plumbing.

4. Removing the old valve.

5. Installing a new, high-quality valve.

Depending on the location of the valve and the complexity of your well system, this task may require the expertise of a qualified plumber. Attempting to replace a foot valve yourself can be especially challenging as it necessitates pulling the pump from the well.

While pinpointing those hidden leaks can feel like detective work, sometimes the issue lies deeper within your well system itself. A crucial component often overlooked is the check valve and foot valve. When these fail, they can lead to a frustrating problem: water flowing backward, causing your pump to work overtime and potentially run non-stop. But what happens when the valves are functioning correctly, and the plumbing is sound? In those scenarios, the culprit could very well be the pump itself.

Problem #5: Well Pump Issues – Is the Pump Itself the Problem?

While external factors often contribute to a constantly running well pump, it’s crucial not to dismiss the possibility of internal pump failure. The well pump, whether a submersible or jet pump, is the heart of your water system. When it falters, it can lead to a continuous operation cycle, signaling a more serious problem.

Understanding Pump-Related Issues

Well pumps are robust pieces of machinery, but they’re not immune to wear and tear. Over time, components can degrade, leading to inefficiencies and ultimately, failure. It’s important to understand that the type of pump you have—submersible or jet—will influence the specific issues you might encounter.

Submersible pumps, submerged directly in the well, are generally less susceptible to priming issues. However, they can suffer from motor burnout, impeller damage, or electrical problems within the pump housing. Sediment buildup can also significantly reduce their efficiency, forcing them to run longer to deliver the same amount of water.

Jet pumps, located above ground, are more prone to cavitation (formation of air bubbles) and loss of prime. Their impellers can wear down, and the jet nozzle can become clogged, reducing their ability to draw water effectively.

Recognizing the Symptoms

Several telltale signs indicate a potential problem with the well pump itself:

• Unusual Noises: Grinding, whining, or excessively loud humming from the pump can suggest bearing failure, impeller damage, or other mechanical issues.

• Decreased Water Pressure: A noticeable drop in water pressure, even when the pump is running, could indicate that the pump is not operating at its full capacity.

• Pump Doesn’t Shut Off: This is the most obvious sign and the primary focus of this article. If the pump runs continuously, even when no water is being used and the pressure tank should be full, the pump itself is a prime suspect.

Diagnosing the Root Cause

Pinpointing the exact cause of pump failure often requires professional expertise. However, here are some initial diagnostic steps you can take:

• Check Voltage and Current: Using a multimeter, verify that the pump is receiving the correct voltage and amperage. Fluctuations or abnormalities can indicate electrical problems within the pump motor. However, exercise extreme caution when working with electricity and consult a qualified electrician if you are not comfortable.

• Listen Carefully: Pay close attention to the sounds coming from the pump. Unusual noises can provide clues about the nature of the problem.

• Call a Plumber: If the above steps don’t reveal the issue, it’s time to call in a qualified plumber or well service technician. They have specialized equipment and expertise to diagnose complex pump problems. They can perform tests like a pump performance test to measure the pump’s output and efficiency, or a down-well camera inspection to visually inspect the pump and well casing.

The Solution: Pump Replacement

Unfortunately, when a well pump fails, replacement is often the most cost-effective and reliable solution. While some minor repairs may be possible, they are often temporary fixes. A new well pump will restore your water pressure and ensure reliable water delivery for years to come.

Choosing the right replacement pump is crucial. Consider factors like well depth, water demand, and the type of pump (submersible or jet) best suited for your specific situation. A qualified plumber can help you select the appropriate pump and ensure proper installation. While the initial cost of a new pump can be significant, it’s an investment in the long-term reliability of your water system. Ignoring the signs of a failing pump can lead to further damage and even more costly repairs down the line.

So, if you’re scratching your head wondering about what causes a well pump to run constantly, try these fixes! Hopefully, you’ll be back to enjoying a quiet, efficient water system in no time. Good luck, and happy troubleshooting!
