Quick answer:
When a well-fed home suddenly has no water, go to the breaker panel first. A tripped double-pole circuit breaker is the single most common cause of complete water loss and takes 30 seconds to fix. If the breaker is fine, check the pressure switch contacts (2 minutes) and the pressure tank bladder (2 minutes). These three checks cost nothing and resolve the majority of no-water calls without a contractor. If all three check out, the problem is the pump itself, a frozen component, the well running dry, or a failed check valve — each with specific actions described below. Do not call anyone and do not pay an emergency rate until you have done these checks. If you hear the pump running but no water is coming, turn the pump off at the breaker immediately — running a submersible pump without water destroys it within minutes.
No water at the tap is one of the most alarming things that can happen in a home. The instinct is to call a contractor immediately. That instinct is often wrong and always expensive if you have not done five minutes of self-diagnosis first. Many no-water situations are caused by a tripped breaker, a bumped shutoff switch, a stuck pressure switch, or a temporarily overtaxed well that just needs an hour of rest. None of these require a contractor.
The causes that do require professional help — a failed pump, a cracked drop pipe, a permanently dry well — cannot be reached without first ruling out the simpler causes anyway. So the diagnostic sequence below is the right path regardless of the eventual outcome. Work through it in order.

Safety First: What to Do Before Touching Anything
Well pump systems operate on 240-volt circuits. That is twice the voltage of a standard household outlet and enough current to cause serious injury or death. Before you open any electrical component on the well system:
Turn off the circuit breaker
Turn off the circuit breaker for the well pump before opening the pressure switch housing or touching any wiring. The pump breaker is a double-pole breaker (two switches connected by a bar) in your main electrical panel. It is labeled "well pump," "water pump," or sometimes just "pump."
Use a non-contact voltage tester
These cost $15 to $25 at any hardware store and confirm that a circuit is dead before you touch it. Never assume a circuit is dead because the breaker is off.
Do not repeatedly reset a breaker that keeps tripping
A breaker that trips again immediately after reset indicates a short circuit or motor failure. Continued resetting can cause a fire or permanently damage the pump wiring.
The 5-Minute Check Sequence
Do these four checks before anything else. They are in order of likelihood and speed.
Check 1: The Circuit Breaker (30 Seconds)
Go to your main electrical panel. Find the double-pole breaker labeled for the well pump. A tripped breaker sits in a middle position between ON and OFF, not firmly in either direction. It may also be fully OFF because it tripped through OFF.
To reset: push the breaker firmly to OFF, then flip it firmly to ON. You should hear a click. Go turn on a faucet and wait 60 seconds. If water flows, you are done.
If the breaker trips again immediately, stop. Do not reset it a third time. A breaker that trips immediately indicates a short circuit in the pump motor, wiring, or control box. Call a licensed well contractor.
Also check: many older systems and some newer ones have a separate well shutoff switch, often a red or standard toggle switch mounted on the wall near the pressure tank. It can be bumped accidentally. Make sure it is in the ON position before going further.
Check 2: The Pressure Gauge (1 Minute)
Look at the pressure gauge on your system. It is typically mounted at the pressure tank tee or on the supply pipe near the tank. The needle tells you a great deal.
| Gauge Reading | Pump Sound | What It Means | Go To |
|---|---|---|---|
| Zero | Silent | No power or pressure switch not starting pump | Check 3 (pressure switch) |
| Zero | Running | Pump running but not delivering water — dry well or failed pump | Cause 4 and Cause 5 — turn off pump |
| Normal (30–60 PSI) | Running | Blockage between tank and fixtures — not a well problem | Check shutoff valves and sediment filters |
| Normal (30–60 PSI) | Silent | System still pressurized — you may have water, check again | Open a faucet and wait |
| Stuck, does not move | Any | Gauge may have failed — proceed to Check 3 regardless | Check 3 |
Gauge reads zero and pump is not running: No power is reaching the pump, or the pressure switch is not sending the start signal. Go to Check 3.
Gauge reads zero and you can hear the pump running: The pump is running but not delivering water. This is serious. Turn off the pump at the breaker immediately to prevent dry-run damage, then see Cause 4 and Cause 5 below.
Gauge reads a normal pressure (30 to 60 PSI) but no water flows at fixtures: The blockage is between the pressure tank and the fixtures — a shutoff valve accidentally closed, a frozen pipe between the tank and the house, or a completely clogged sediment filter. These are plumbing issues, not well issues.
Gauge needle is stuck and does not move: The gauge itself may have failed. This is less informative but does not change the diagnostic sequence. Proceed to Check 3.
Check 3: The Pressure Switch (3 Minutes)
The pressure switch is a small gray or black box mounted on a quarter-inch sensing tube near the pressure tank. It senses system pressure and sends the electrical signal that starts and stops the pump.
With the pump breaker OFF and confirmed dead with a voltage tester:
Remove the plastic cover of the pressure switch (one nut at the top holds it). Look at the electrical contacts inside. They should be copper-colored, shiny or dull copper. If they appear black, heavily pitted, or show burn marks, the switch contacts have failed and are not closing to start the pump.
Temporary fix for burned contacts: with power still off, use a nail file or emery board to lightly sand the contact surfaces until you see copper color. This is a temporary measure only. Replace the switch as soon as possible. A new pressure switch costs $20 to $50.
Also check: look inside the switch for insects. Ants colonize pressure switches regularly and can bridge the contacts, preventing proper operation. If you see ants, clear them out and check whether the contacts were damaged.
Also check: the quarter-inch sensing tube connecting the switch to the pipe. In cold weather this small tube is the first component to freeze. If it is winter and temperatures have been below freezing, the sensing tube may be blocked with ice. See the Frozen System section below.
Restore power and test. If the pump starts and water flows, check complete.
Check 4: The Pressure Tank (2 Minutes)
If power is reaching the system but no water is flowing, check whether the pressure tank has failed. A waterlogged tank (bladder failure) does not directly cause complete loss of water, but a failed tank combined with a pump that is struggling can result in no usable water pressure.
Quick tank test: with the pump breaker OFF, open a faucet and drain the system until flow stops. Press the Schrader valve (tire-valve stem) on top of the tank. Air should come out. If water sprays out, the bladder has failed.
A waterlogged tank combined with a pump that is failing can result in effectively no water delivery even though the pump is running. If the tank test shows bladder failure and you also have no water, the tank needs replacement and the pump should be assessed separately.
Tripped Breaker or Power Loss
Who it affects: Everyone. No exceptions.
Why it happens: Submersible pumps draw high starting current every time they start. Over years of cycling, this strains the breaker. Breakers also trip when the pump motor draws excess current due to a tight impeller, low voltage, or a partially failed motor winding. A single trip that resets successfully is usually a fluke. A breaker that trips repeatedly means something is drawing too much current.
What to check: Reset once as described in Check 1. If it holds, run water normally for 10 minutes and observe. If it trips during use, have a contractor check the pump's amp draw. Normal amp draw is printed on the pump motor nameplate. If the pump is drawing more than rated amps, the motor is failing.
Cost to fix: Nothing if it was a fluke trip. Breaker replacement: $15 to $40 for the part, simple electrical work. Motor replacement: $400 to $2,500 for the full pump replacement if the motor has failed.
Failed Pressure Switch
Who it affects: Any well system.
Why it happens: Pressure switches cycle on and off dozens of times per day. The electrical contacts gradually pit and corrode. Age, insects, moisture intrusion, and sediment in the sensing tube all accelerate failure. The average pressure switch lasts 5 to 10 years.
Symptoms: Pump does not start when it should. Gauge reads zero. Power is reaching the switch but the pump does not activate. Contacts look black or burned inside the switch housing.
DIY repair: A pressure switch is one of the few well system components that many homeowners can replace themselves. Turn off power, confirm it is dead, label the wires, remove the old switch, thread in the new switch with pipe dope on the threads, and reconnect the wires. New switch: $20 to $50. Takes about 30 minutes.
Important: when you replace a pressure switch, check the pressure tank air charge immediately after. The air pre-charge must be 2 PSI below the cut-in pressure of the new switch. If you install a 30/50 switch, the tank needs 28 PSI pre-charge. If you install a 40/60 switch, the tank needs 38 PSI.
Contractor cost: $150 to $300 including parts and labor if you prefer not to DIY.
Frozen Pipes or Frozen Pressure Switch Sensing Tube
Who it affects: Well systems in freezing climates, systems in unheated spaces, systems with inadequate insulation.
Why it happens: Two separate freeze scenarios cause no-water in winter. The more common and less serious one is a frozen pressure switch sensing tube. The small quarter-inch tube that connects the pressure switch to the plumbing is the first thing to freeze in any cold snap because its small volume chills rapidly. When ice forms in this tube, the switch cannot sense pressure changes and will not start the pump. The pump is fine. The well is fine. Only this tiny tube is frozen.
The more serious scenario is a frozen supply pipe between the well and the house or within the home in an unheated space. If the pipe connecting the pitless adapter to the house supply line freezes, no water can flow regardless of whether the pump is running.
How to tell them apart: Turn on the pump breaker. Listen at the wellhead or at the pressure tank. Is the pump running but no water building in the system? That points to a frozen supply pipe. Is there no pump sound at all and the gauge reads zero? That points to a frozen sensing tube or frozen pressure switch.
Frozen sensing tube fix: Identify the small quarter-inch tube running from the bottom of the pressure switch to the pipe. Apply a hair dryer to this tube on low heat. It takes 2 to 5 minutes. Do not apply open flame. Restore power and test. Once thawed, insulate the tube with pipe foam and seal any air drafts reaching that area.
Frozen supply pipe: Do not run the pump while the supply pipe is frozen. Running a submersible pump with a blocked discharge line risks catastrophic pressure buildup. Locate the frozen section and apply gentle heat (hair dryer, heating pad, warm wet towels) starting at the faucet end and working back toward the well. Never use open flame on pipes.
If you cannot locate the frozen section or if the pipe runs underground between the well and the house at insufficient depth, call a plumber. Improperly thawing a frozen pipe can cause it to burst.
Prevention: Insulate the pressure switch sensing tube. Keep the utility room or pump house above 40 degrees Fahrenheit. Make sure the supply line from the well to the house is buried below the frost line for your region.
Failed Well Pump
Who it affects: Any well system, particularly those with pumps more than 10 years old.
Why it happens: Submersible pump motors wear out. Common failure modes include burned motor windings from sustained overcurrent, worn bearings from long-term operation, failed starting capacitor (three-wire systems) or internal starting components (two-wire systems), and impeller damage from sand or sediment.
Symptoms specific to pump failure:
The breaker trips repeatedly. Pump failure often manifests as a motor drawing excessive current, which trips the breaker. A breaker that trips immediately and consistently (not just once) points to motor failure or a wiring short.
The pump hums but does not start and no water flows. The motor is receiving power but cannot develop starting torque. On three-wire systems, this is almost always a failed start capacitor in the control box above ground. Replace the capacitor ($30 to $75) before concluding the pump itself has failed.
No sound from the pump at all when the breaker is on and the pressure switch contacts are confirmed closed. The motor has failed or wiring has failed between the switch and the pump.
Pump was running dry and you are certain of it. Running a submersible dry destroys the motor within minutes by removing the water cooling from the motor housing. If the well ran completely dry and the pump kept running, assume motor damage.
What you can check yourself: On three-wire systems, open the control box (the gray or beige box mounted above ground near the pressure tank). Look for a bulging, burned, or visibly failed start capacitor. Replace it with an exact match. This is a $30 to $75 fix that does not require pulling the pump.
What requires a contractor: Any pump problem that is not the control box components requires pulling the pump from the well. This requires a cable or tripod rig to safely extract the pump and drop pipe from potentially hundreds of feet down. This is not DIY work. Average pump replacement cost: $400 to $2,500 depending on depth and pump size.
Well Running Dry or Low Yield
Who it affects: Shallow wells, wells in drought-prone areas, wells in late summer and early fall when water tables reach their annual lowest point, wells that have been heavily pumped.
Why it happens: According to the USGS, a well is said to have gone dry when water levels drop below the pump intake. This does not mean the well is permanently dry. The water level may recover as recharge increases. Shallow, unconfined aquifer wells are the most vulnerable to seasonal fluctuation. Deeper wells in confined aquifers are more stable but not immune.
The natural annual cycle of groundwater levels produces the lowest water tables in late summer and early fall in most of the continental US. The Penn State Extension well drought resources document that shallow wells may see water levels rise and fall more quickly with rainfall, while deeper wells tend to withstand drought better but may take longer to recover.
Symptoms that distinguish a dry well from a failed pump:
Sputtering, air in the water, and intermittent flow before complete loss. When the water table drops to near the pump intake, the pump draws a mix of water and air before losing water entirely. This sputtering phase is the signature of a declining water level.
Water loss coincides with heavy demand, drought, or late summer. If the well ran fine all spring and stopped in August after a dry summer or after running the irrigation system heavily, the water table is the likely cause.
Neighbors on wells in the same area report the same problem. Regional aquifer drawdown affects multiple wells simultaneously.
Water that was turbid, gritty, or discolored just before loss. The pump drawing from near the well bottom pulls sediment before losing water entirely.
What to do when you suspect the well has run dry:
Turn off the pump at the breaker immediately. Running a submersible pump dry destroys it rapidly. This is the single most important action when you suspect a dry well.
Wait 1 to 2 hours, then restore power and try again with minimal demand. If the aquifer is temporarily depleted from heavy use, a rest period allows some recovery. Use water sparingly for the rest of the day.
If the well recovers after rest but continues to struggle during normal use, you have a yield limitation that needs professional assessment. A contractor can measure the static and dynamic water levels to determine how much water the well is actually producing and recommend solutions.
Long-term solutions for a well with yield problems:
Lower the pump to a deeper setting within the existing borehole if the current pump position allows it. This may reach water that the current setting cannot.
Hydrofracture the existing well (sometimes called hydro-fracking for wells, not to be confused with oil and gas fracking). High-pressure water is injected into the borehole to open fractures in surrounding bedrock, potentially increasing yield. Cost: $1,500 to $3,000.
Deepen the existing well by drilling further through the bottom of the borehole. Cost varies significantly by geology and depth required.
Drill a new well. If the existing well location has reached its productive limit, a new well at a better location or deeper depth may be the only permanent solution. Cost: $6,000 to $16,000 depending on depth and location.
Failed Check Valve
Who it affects: Any well with a submersible pump.
Why it happens: The check valve is a one-way valve located just above the submersible pump. It prevents pressurized water from draining back into the well when the pump shuts off. When the check valve fails (the valve seat wears or debris holds the valve open), the water column in the drop pipe drains back into the well every time the pump shuts off. The pump has to refill the entire drop pipe from scratch every time it starts, which takes longer than normal and depletes the pressure tank before pressure builds.
Symptoms: Pressure drops to zero more quickly than normal after the pump shuts off. The pump short-cycles (turns on and off frequently) without the bladder-failure signature. You can hear the water draining back down the drop pipe after the pump shuts off (a gurgling sound at the wellhead).
Why it matters here: A failed check valve alone does not usually cause complete loss of water, but a failed check valve in combination with a marginally performing pump, an undersized pressure tank, or heavy demand can result in effectively no usable pressure. Address check valve failure promptly.
Fix: Replacing a check valve requires pulling the pump from the well. Contractor work. Cost: typically absorbed into the service call, $150 to $400 for the visit plus valve replacement.
Broken Drop Pipe or Wiring
Who it affects: Older systems, systems with deteriorated materials, systems after electrical events.
Why it happens: The drop pipe is the pipe that carries water from the pump up through the well casing. It is typically PVC plastic in 20-foot threaded sections. After years in the well, thread couplings can crack or fail. A cracked drop pipe means the pump is delivering water, but some or all of it is dropping back into the well casing rather than reaching the surface.
Similarly, the electrical wiring running alongside the drop pipe can suffer insulation failure after years of immersion. A wiring failure between the control box and the pump may allow the pump to receive some power but not enough to run at full capacity, or may cause intermittent operation.
Symptoms: Pump runs but no water or very little water reaches the surface despite confirmed pump operation. The breaker does not trip. The pump hums normally but pressure does not build.
Fix: Drop pipe failure and wiring failure both require pulling the pump. Contractor work. A contractor doing a pump service call will inspect the drop pipe and wiring before concluding the pump has failed.
The No-Water Decision Tree
Use this to find your situation quickly:
No sound from system, gauge reads zero, power is on
Check the breaker first. If the breaker is fine, check the pressure switch contacts. If contacts are burned, replace the switch. If contacts are clean, check for a frozen sensing tube in winter. If none of the above, the pump wiring or motor has failed — call a contractor.
Pump runs, gauge reads zero, no water delivered
The pump is running but not moving water. Possible causes: dry well (water table below intake), failed pump impellers, cracked drop pipe. Turn off the pump immediately to prevent dry-run damage. Call a contractor.
Pump runs, gauge builds pressure briefly, pressure then drops quickly
Failed check valve or a leak in the supply line from the well to the house. If the gauge drops slowly, check for wet ground between the wellhead and the house (indicating a buried pipe leak). If it drops quickly, the check valve is the likely culprit.
No water only in winter, system was working fine before the cold
Frozen pressure switch sensing tube or frozen supply pipe. Thaw the sensing tube first. If that does not restore water, locate and thaw the supply pipe.
Water sputtered and had air in it before going completely dry
The well is likely running dry. Turn off the pump, wait 1 to 2 hours, try again with minimal use. If water returns, you have a yield limitation.
Breaker trips immediately upon reset
Short circuit in the motor or wiring. Do not reset again. Call a contractor.

|---|---|
| The breaker tripped once and resets cleanly | DIY — done |
| The pressure switch contacts are burned | DIY — replace the switch ($20–$50) |

| The pressure switch sensing tube is frozen | DIY — hair dryer fix |
| You suspect the well ran dry | DIY — rest the well first before calling |
| The breaker trips immediately and repeatedly | Call contractor same-day |
| The pump runs but delivers no water and the well is not dry | Call contractor same-day |
| You smell burning from the pressure switch or control box | Call contractor same-day |
| Water has returned but pressure remains very low after all checks | Call contractor same-day |
| You cannot identify the cause after working through this sequence | Call contractor same-day |
| The well appears to have a yield limitation | Call contractor — no emergency |
| The check valve appears to have failed | Call contractor — no emergency |
| The pump is more than 12 years old with intermittent failures | Call contractor — no emergency |
Temporary Water Solutions While You Wait for Repairs
If you are without water and waiting for a contractor, here are your immediate options:
Bottled water for drinking and cooking. Plan for approximately one gallon per person per day minimum for drinking and sanitation.
Fill bathtubs and large containers before the water stops entirely if you have warning. A standard bathtub holds 40 to 60 gallons, enough for toilet flushing for several days.
For toilet flushing, a bucket of water poured directly into the toilet bowl (not the tank) will flush it.
Contact your local fire department or emergency management office if you are in a prolonged outage. Many rural areas have emergency water delivery resources for households without water.
What a Contractor Will Do on a No-Water Call
Understanding what a contractor actually does on arrival helps you know whether the work is appropriate and the price is fair.
First, they will run through the same electrical checks described above: breaker, pressure switch, control box. Any competent contractor starts at the cheap stuff.
Next, they will test pump motor performance with an amp clamp. This measures whether the pump is drawing current within the nameplate range. A motor drawing higher than rated amps is failing. A motor drawing zero amps is not running at all.
If the pump motor is confirmed failed, they will pull the pump. This requires a cable puller or tripod, is physical work, and typically takes 2 to 4 hours for a standard residential well. They will inspect the drop pipe and wiring as they pull.
They will quote you pump replacement on the spot once they can see the pump specifications. Get the pump brand, model, and horsepower confirmed in writing before you agree to replacement. The replacement pump should match the original specifications unless the contractor recommends otherwise with a clear explanation.
After installation they will run the system through several pressure cycles to confirm proper operation and measure the pump output in gallons per minute to confirm adequate yield.
Average cost: $400 to $2,500 for a complete pump replacement depending on depth, pump size, and labor rates in your region. Emergency or weekend rates add $150 to $300 to the call.

Glossary
Circuit Breaker, Double-Pole
The electrical protection device for the well pump circuit. Well pumps run on 240 volts and require a double-pole breaker (two switches connected by a bar) in the main electrical panel. A tripped breaker sits between ON and OFF. Reset by pushing firmly to OFF then to ON. A breaker that trips immediately upon reset indicates an electrical fault requiring professional diagnosis.
Pressure Switch
The device that senses system water pressure and turns the pump on at a low setpoint and off at a high setpoint. Mounted near the pressure tank on a small sensing tube. A failed pressure switch is among the most common causes of a pump not starting. New switch costs $20 to $50 and is one of the few well components homeowners can safely replace.
Control Box
The above-ground component box on three-wire well pump systems that houses the start capacitor, run capacitor, and relay for the pump motor. Mounted on a wall near the pressure tank. A failed start capacitor in the control box is the most common fixable cause of a well pump that hums but does not start. Control box components cost $30 to $150 to replace without pulling the pump.
Check Valve
A one-way valve located just above the pump in the drop pipe that prevents water from draining back into the well when the pump stops. Check valve failure causes pressure to bleed down quickly after the pump shuts off and requires pulling the pump for replacement.
Static Water Level
The depth from the surface to the water level in the well when the pump is not running. When drought or overuse drops this level below the pump intake, the well has effectively run dry. Recovery time depends on the aquifer type and local rainfall.
Dry-Run Damage
Damage to a submersible pump motor that occurs when the pump runs without water flowing past the motor housing. Submersible motors are water-cooled. Without water, heat builds rapidly and destroys motor windings and bearings within minutes. Suspected dry-run is the most urgent reason to shut off the pump breaker immediately.
