The Frustration of a Dry Tap: Why Is Your Well Not Working?

There’s a unique brand of frustration that comes with turning on the tap and finding nothing but air. It’s more than just an inconvenience; it disrupts daily life, turning simple tasks like showering, cooking, and even flushing the toilet into logistical nightmares.

The sudden silence where the familiar rush of water should be is a stark reminder of our dependence on this often-overlooked resource. A well that suddenly stops working can be a major source of stress for homeowners.

This guide is designed to alleviate that stress by providing a clear, step-by-step methodology for troubleshooting your well system. We aim to empower you, the homeowner, to identify potential problems and, in some cases, resolve them yourself.

Empowering Homeowners Through Knowledge

Our goal is to equip you with the knowledge and confidence to tackle common well issues. By understanding the basics of your well system and following our systematic approach, you can potentially save time, money, and a whole lot of frustration.

However, before we dive in, it’s crucial to emphasize one overriding principle: safety first.

The Primacy of Safety

Working with water well systems often involves dealing with both electricity and pressurized water. These elements can be dangerous if not handled correctly. Always exercise extreme caution when inspecting or working on any part of your well system.

• Electricity: Never work on electrical components while they are energized. Always disconnect the power at the circuit breaker before attempting any electrical work. If you are not comfortable working with electricity, call a qualified electrician.
• Water Pressure: Be aware that pressurized water can cause injury if released suddenly. Relieve pressure in the system before disconnecting any pipes or fittings.
• Well Integrity: Avoid any actions that could compromise the structural integrity of the well itself. This could lead to collapse or contamination.

Understanding Your Limits

While this guide aims to provide comprehensive troubleshooting advice, it is not a substitute for professional expertise. If you are unsure about any step, or if you encounter a problem that you are not comfortable handling, do not hesitate to call a qualified well service professional or licensed plumber. Your safety, and the long-term health of your well system, are paramount.

Understanding Your Water Well System: Key Components

Before you can effectively troubleshoot a well system, it’s essential to understand how all its components work together. Think of your well system as a chain; if one link fails, the entire system is compromised.

The Interconnected System

The well itself acts as the source, tapping into underground aquifers. The well pump then draws water from the well and sends it through piping to a pressure tank inside your home or a nearby structure.

The pressure switch monitors the water pressure and tells the pump when to turn on and off to maintain consistent water flow. Wiring provides the electrical power needed to run the pump. Each part depends on the others to function properly.

Key Components Explained

Let’s examine each of these components in more detail:

The Water Well

The water well is more than just a hole in the ground. It’s a carefully constructed access point to an underground aquifer, designed to prevent contamination and ensure a reliable water supply.

The well casing, typically made of steel or PVC, lines the borehole to prevent collapse and keep surface water from seeping into the well.

The well screen, located at the bottom of the casing, filters out sediment and debris while allowing water to flow into the well.

The Well Pump (and Pump Motor)

The well pump is the heart of your water system, responsible for drawing water from the well and delivering it to your home. The pump motor powers the pump, providing the mechanical energy needed to move water.

Different types of pumps exist, each with its own strengths and weaknesses, which we will discuss later. A failing pump is one of the most common causes of well problems.

The Pressure Tank

The pressure tank is a crucial component that helps maintain consistent water pressure throughout your home. It stores water under pressure, reducing the number of times the pump needs to cycle on and off.

This helps extend the life of the pump and prevents pressure fluctuations that can be annoying and damaging to your plumbing.

The Pressure Switch

The pressure switch acts as the brains of the operation, monitoring the water pressure in the tank and signaling the pump to turn on when the pressure drops below a certain level.

When the pressure reaches the upper limit, the switch turns the pump off. A malfunctioning pressure switch can cause the pump to run continuously or not at all.

Piping and Wiring

Piping carries water from the well to your home, and wiring delivers the electrical power to the pump.

Both must be in good condition to ensure efficient and reliable operation. Look for leaks, cracks, or corrosion in the piping, and check the wiring for damage or loose connections.

Submersible vs. Jet Pumps

Two primary types of well pumps are commonly used: submersible pumps and jet pumps.

Submersible pumps are designed to be submerged in the water inside the well. They are highly efficient and can lift water from greater depths.

These are generally preferred for deeper wells, and are less noisy since they operate underwater.

Jet pumps are located above ground and use suction to draw water from the well.

They are typically used for shallower wells, but are less efficient and can be more prone to cavitation (the formation of air bubbles in the water). Because they are above ground, they are often easier to service.

Initial Checks: Easy Fixes and Quick Wins

Now that you have a basic understanding of the components, let’s move on to some simple troubleshooting steps. Often, a well system failure is due to something easily remedied, saving you time and money on more complex repairs. These initial checks require minimal technical expertise and can potentially resolve the issue quickly.

The First Line of Defense: Simple Checks

Before diving into more complicated diagnostics, focus on the most common and easily addressable causes of well system failure.

Check the Circuit Breaker

The first place to start is your electrical panel. Locate the circuit breaker that controls the well pump. It should be clearly labeled. If the breaker is in the "tripped" position (usually indicated by being in the middle or fully switched to the "off" position), reset it by flipping it completely to the "off" position and then back to the "on" position.

Sometimes, a breaker trips due to a temporary power surge or an overload. If the breaker trips again immediately after resetting, this indicates a more serious electrical problem that needs professional attention. Do not repeatedly reset a tripping breaker; this could damage your equipment or pose a fire hazard.

Inspect Electrical Wiring

Visually inspect all accessible electrical wiring connected to the well pump, pressure switch, and control box (if applicable). Look for any signs of damage, such as:

• Frayed or cracked insulation
• Loose connections
• Corrosion or rust
• Burn marks or melting

Loose connections are a common culprit. If you find any, carefully tighten them with a screwdriver, but only if you are comfortable and confident doing so. If the wiring is severely damaged or you are unsure about making electrical repairs, call a qualified electrician. Remember, safety first.

Control Box Inspection (Submersible Pumps)

If you have a submersible well pump, it likely has a control box mounted near the pressure tank or electrical panel. This box contains the starting capacitor and other electrical components needed to run the pump.

Carefully inspect the control box for any of the following:

• Unusual sounds, such as buzzing or humming
• Burning smells
• Visible damage, such as cracks or bulges
• Rust or corrosion

If you notice any of these signs, the control box may be faulty and need to be replaced. Replacing a control box is often a simple fix, but it’s crucial to use the correct replacement part for your pump model.

Verify Power to the Well Pump

Even if the circuit breaker is on, it’s still possible that power isn’t reaching the well pump. To verify this, use a non-contact voltage tester. This tool allows you to check for the presence of electricity without physically touching any wires.

Follow the manufacturer’s instructions for your voltage tester. Typically, you’ll hold the tester near the wires leading to the well pump or control box. If the tester indicates the presence of voltage, then power is reaching the pump. If not, the problem lies somewhere upstream, such as in the wiring or the circuit breaker itself.

Caution: Always exercise extreme caution when working with electricity. If you are not comfortable using a voltage tester or working with electrical wiring, call a qualified electrician.

If these simple checks don’t solve the problem, it’s time to move on to more advanced diagnostics. But you might be surprised how often a tripped breaker or loose wire is the cause of a non-working well.

Investigating the Well Pump: Is It Running?

After checking the easily accessible electrical components, the next step is to determine if the well pump itself is functioning. This requires carefully listening for any signs of activity and observing the pump motor for any indications of distress.

Listening for Pump Operation

The first, and simplest, diagnostic step is to listen closely for the sound of the pump running.

This can be done in a couple of ways.

• At the Well Casing: Carefully place your ear near the well casing (the exposed pipe coming out of the ground). Be cautious of insects and sharp edges. Can you hear a hum, whir, or any other indication that the pump motor is running?

• At the Pressure Tank: Alternatively, listen near the pressure tank. The sound of the pump running may be transmitted through the pipes.

If you hear the pump running, but no water is flowing, it suggests a different set of problems than if the pump is completely silent.

If you hear no sound at all, proceed to the next diagnostic steps. This indicates a potential issue with power supply to the pump, or a complete pump failure.

Recognizing an Overheating Pump Motor

If the pump is running, it’s crucial to determine if it’s running correctly. An overheating pump motor is a serious sign of underlying problems.

• Touch Test: Carefully touch the pump motor (if accessible and safe to do so). If it’s excessively hot to the touch, it could be overheating.

• Smell Test: Sniff around the pump motor. A burning smell is a clear indication of overheating and potential electrical damage.

Several factors can cause a pump motor to overheat:

• Low Water Level: If the water level in the well has dropped below the pump intake, the pump will run dry. This causes excessive friction and heat.
• Blocked Impeller: The impeller is the rotating component inside the pump that moves water. If it becomes blocked by sediment or debris, the motor will have to work much harder, causing it to overheat.
• Electrical Issues: Internal electrical faults within the motor can also cause overheating.

An overheating pump motor can be a fire hazard. If you suspect overheating, immediately shut off the power to the pump at the circuit breaker and call a qualified well service professional.

Checking the Water Level (Proceed with Extreme Caution!)

A low water level in the well is a common cause of pump failure. If the water level drops below the pump intake, the pump will run dry and eventually overheat or fail.

Warning: Checking the water level in a well can be dangerous and often requires specialized equipment. It is generally best left to a qualified well service professional.

However, in some circumstances, you may be able to safely check the water level yourself:

• Existing Access: Some wells have a dedicated access port for measuring the water level. This usually involves removing a cap or plug.

• Weighted Line: A common method involves using a weighted measuring line. Lower the line into the well until it reaches the water. Measure the length of the wet portion of the line. This provides an estimate of the water level.

If the water level is significantly lower than the pump intake, this indicates that the well is running dry. Conserving water and calling a well service professional for further evaluation are crucial. Continued operation of the pump in a low-water situation will likely result in permanent damage.

Pressure Tank and Switch Issues: Diagnosing Pressure Problems

Having investigated the well pump itself, and assuming it’s either not running or showing signs of distress like overheating, it’s time to shift our attention to two critical components that directly influence water pressure: the pressure tank and the pressure switch. These components work in tandem to ensure a consistent and reliable water supply. Issues with either can lead to erratic pump behavior or even complete system failure.

Understanding the Role of the Pressure Tank

The pressure tank is more than just a storage vessel; it’s a key regulator of water pressure in your home. Think of it as a buffer between the well pump and your plumbing fixtures.

Its primary function is to store water under pressure, creating a readily available supply that minimizes the need for the pump to cycle on and off constantly.

Inside the tank, a bladder or diaphragm separates the water from compressed air.

As water is pumped into the tank, it compresses the air, building pressure. When you open a faucet, the compressed air forces water out of the tank and into your pipes.

This system allows for consistent water pressure even when the pump isn’t actively running. Without a properly functioning pressure tank, you might experience fluctuating water pressure, or worse, premature pump failure due to excessive cycling.

Testing the Pressure Switch

The pressure switch acts as the brain of the system, monitoring water pressure and signaling the pump to turn on or off as needed. It’s typically a small, electrical device mounted near the pressure tank.

It has preset pressure thresholds: a cut-in pressure (the pressure at which the pump turns on) and a cut-out pressure (the pressure at which the pump turns off).

Checking the Switch:

To test the pressure switch, first, locate it near the pressure tank.

Observe the pressure gauge on the tank as you use water in your home. Note the pressure at which the pump turns on (cut-in) and the pressure at which it turns off (cut-out).

These pressures should align with the settings indicated on the pressure switch itself. If the pump isn’t turning on or off at the correct pressures, the switch may be faulty.

Another test you can perform is carefully tapping on the pressure switch housing. Sometimes, mineral buildup or debris can interfere with its operation. A gentle tap can dislodge these obstructions.

Caution: Always turn off the power to the well pump circuit breaker before working with the pressure switch to avoid electrical shock.

If the switch still doesn’t function correctly after tapping, it may need to be replaced.

Checking Air Pressure in the Pressure Tank

Maintaining the correct air pressure in the pressure tank is vital for optimal system performance. Incorrect air pressure is a common cause of "short cycling," where the pump turns on and off rapidly, leading to premature wear and tear.

Procedure:

1. Turn off the well pump circuit breaker.
2. Drain all the water from the pressure tank by opening a faucet at the lowest point in your plumbing system.
3. Locate the Schrader valve (similar to a tire valve) on top of the pressure tank.
4. Use a tire pressure gauge to check the air pressure.
5. The air pressure should be 2 PSI below the cut-in pressure of the pressure switch. For example, if the cut-in pressure is 30 PSI, the air pressure should be 28 PSI.
6. If the air pressure is too low, use an air compressor to add air to the tank. If it’s too high, depress the Schrader valve to release air.
7. Once the air pressure is correct, close the faucet, turn the well pump circuit breaker back on, and allow the tank to refill.

By carefully diagnosing and addressing issues with the pressure tank and pressure switch, you can often restore proper water pressure and prevent more serious problems down the line.

Having investigated the well pump itself, and assuming it’s either not running or showing signs of distress like overheating, it’s time to shift our attention to two critical components that directly influence water pressure: the pressure tank and the pressure switch. These components work in tandem to ensure a consistent and reliable water supply. Issues with either can lead to erratic pump behavior or even complete system failure.

When to Call a Professional: Recognizing Your Limits

Troubleshooting a well system can often be accomplished by a diligent homeowner, but there comes a point where specialized knowledge, tools, and safety precautions become paramount. Knowing when to step back and call in a professional isn’t a sign of defeat; it’s a sign of wisdom and a commitment to your safety and the long-term health of your well system.

Understanding the Boundaries of DIY

While this guide aims to empower you with the knowledge to diagnose common well problems, it’s crucial to recognize the limitations of do-it-yourself troubleshooting. Attempting repairs beyond your skill level can lead to further damage, potentially dangerous situations, and increased costs in the long run.

Electrical work, in particular, demands caution. Incorrect wiring can result in electrocution or fire. If you’re not comfortable working with electricity or lack the necessary experience, always call a qualified electrician.

Tasks that require specialized equipment, such as pulling a submersible pump from a deep well, are also best left to professionals. These tasks often involve heavy lifting and the risk of dropping equipment into the well, which can create a far bigger problem.

The Value of a Professional Well Inspection

A professional well inspection is more than just a quick check; it’s a comprehensive assessment of your entire well system. Certified well technicians possess the training and experience to identify subtle issues that might go unnoticed by a homeowner.

Moreover, an inspection can provide valuable insights into the overall health and longevity of your well.

Scenarios Requiring Expert Assistance

Certain situations clearly warrant a call to a local well service company or a licensed plumber. These include:

• Pump Failure: If your pump has completely failed and requires replacement, it’s best to hire a professional. Proper pump sizing and installation are essential for optimal performance and efficiency.

• Collapsed Well Casing: A collapsed well casing can contaminate your water supply and render your well unusable. This is a serious issue that requires specialized equipment and expertise to repair.

• Suspected Contamination: If you suspect that your well water is contaminated (e.g., due to nearby construction, agricultural runoff, or septic system failure), do not drink the water. Contact a professional to test your water and recommend appropriate treatment options.

• Low Water Level: If your well consistently runs dry, it may indicate a declining water table or a problem with the well’s construction. A professional can assess the situation and recommend solutions, such as deepening the well or installing a new pump.

• Unusual Noises: Strange or loud noises coming from your well pump or pressure tank can signal a mechanical problem that requires immediate attention.

• Persistent Problems: If you’ve tried troubleshooting the problem yourself without success, it’s time to call in a professional. They have the experience and tools to diagnose and resolve complex well system issues.

• Any Work Involving Dropping Equipment Down The Well: As mentioned above, this is a big issue for contamination, getting equipment stuck, and more

Ultimately, the decision of when to call a professional comes down to your comfort level and the complexity of the problem. When in doubt, it’s always better to err on the side of caution and seek expert help. Your safety and the quality of your water supply are worth the investment.

When you’ve determined the well’s back in working order or sought professional help, and you’re once again enjoying the convenience of running water, the story doesn’t end there. Now, attention shifts to preventative measures. Ensuring consistent maintenance is key to avoiding future disruptions and prolonging the lifespan of your entire well system.

Preventing Future Problems: Regular Maintenance Tips

Neglecting maintenance can lead to unexpected breakdowns, reduced water quality, and costly repairs down the line. By proactively addressing potential issues, you can ensure a reliable and clean water supply for years to come.

The Importance of Proactive Well Maintenance

Think of your well system as an investment. Regular maintenance is the return on that investment. It safeguards against potential problems. This approach saves you money. Also, it provides peace of mind.

It’s far easier and cheaper to prevent a problem. Preventing problems is less stressful than dealing with a full-blown system failure. Establishing a routine maintenance schedule is the best way to do that.

Essential Maintenance Practices

Adopting these practices is a great way to maintain your well and system.

Schedule Professional Well Inspections

Regular well inspections are critical. Aim for at least once every one to three years. A qualified professional can assess the condition of your well. The professional can also identify potential problems. This prevents future issues.

The inspection should include:

• A water level check.
• A flow test.
• A check of the well’s mechanical components.
• Water quality testing.

Maintain Proper Water Chemistry

Water quality can change over time. Regular water testing helps identify changes in pH levels or the presence of contaminants. Addressing these issues promptly is essential for maintaining safe and palatable water.

Consider these issues:

• Testing annually for bacteria, nitrates, and other common contaminants.
• Installing and maintaining appropriate water treatment systems (e.g., water softeners, iron filters) if needed.
• Addressing any signs of corrosion or scaling in your plumbing.

Monitor for Unusual Noises or Performance Changes

Pay attention to any unusual noises coming from your well pump or pressure tank. Strange sounds like grinding, clanking, or excessive cycling can indicate underlying issues that need attention.

Also, be aware of changes in water pressure or flow rate.

Quick responses can prevent minor issues. Quick responses can prevent minor issues from escalating into major problems.

Vigilance Against Sediment Buildup

Sediment in your water is a common problem, especially in older wells. Sediment can clog pipes and damage appliances. It can also reduce the efficiency of your well pump.

Regularly Check and Replace Filters

If your system uses sediment filters, inspect them regularly. Replace them as needed. Clogged filters restrict water flow and put strain on your pump. This can lead to premature failure.

Consider a Whole-House Sediment Filter

A whole-house sediment filter can significantly reduce the amount of sediment entering your home’s plumbing. This is a worthwhile investment if you notice a recurring sediment problem.

Periodic Well Cleaning

In some cases, professional well cleaning may be necessary to remove accumulated sediment. This process involves using specialized equipment. With specialized equipment, loose sediment can be removed from the bottom of the well. Consult with a well service company. They can determine if well cleaning is appropriate for your situation.

So, next time your well stopped working, remember these tips! Hopefully, you can get everything flowing again. Happy troubleshooting!
