Warning signs of a failing well water system.
No water. Weak pressure. A pump that never seems to stop. Follow the clues to understand what your well is telling you—and what to do next.
The quick answer
What are the warning signs of a failing well water system?
Low or fluctuating pressure, no water, sputtering faucets, rapid pump cycling, long pump run times, and new sediment or water-quality changes all deserve attention. They can come from the pump, pressure tank, controls, piping, treatment equipment, or the well itself. A symptom alone cannot tell you which part has failed.
A well that is drying up may lose delivery during heavy use and recover after demand stops. However, overheating pumps and control faults can also cause intermittent water. Water-level measurements and a pumping test help distinguish a supply problem from an equipment problem. [1, 3, 8]
Act promptly: stop using suspect drinking water after flooding, a chemical smell, or an unexplained quality change. Stay away from flooded electrical equipment. If the pump keeps running with no water, switch it off only at a known, safely accessible disconnect and call for help. [3, 10, 11]

Well water problems and solutions at a glance
Start with what changed: the amount of water, the pressure, the pump's behavior, or the water's appearance. That distinction makes the next step much more useful.
A private well system has several jobs. The well admits groundwater, the pump moves it, the pressure tank and controls manage delivery, and the plumbing carries it to your fixtures. Treatment equipment addresses particular water-quality problems. Trouble in one part can look like trouble in another. [2, 5]
| What you notice | What may be behind it | What helps identify the cause |
|---|---|---|
| Suddenly no water | Power or control failure, pump trouble, a closed or blocked supply, a leak, or inadequate water at the intake. | Document the outage, visible gauge reading and control status; arrange service. |
| Water stops during showers or laundry | Demand exceeding delivery, low well yield, or equipment stopping under load. | Record which uses overlap and whether the pump stops or keeps running. |
| Water returns after a rest | Well recovery, a motor cooling down, or a control resetting. | Compare water levels and equipment performance; recovery alone is not a diagnosis. |
| Weak pressure throughout the house | A restricted filter, line, valve, pump, or well supply. | Compare readings at suitable points while water is flowing. |
| Pump starts and stops rapidly | Too little usable tank drawdown, a control problem, or a leak. | Have tank condition, air charge, controls and system leakage checked. |
| Pump runs continuously | An open demand, leak, worn pump, low water level, or inability to reach the shutoff setting. | Identify the system type and whether the run pattern changed. |
| Faucets spit air | Air entering a suction line, water-level problems, a recent repair, or another system fault. | Note whether it affects every fixture and follows heavy use. |
| Pressure drops with all taps off | A hidden demand, leaking pipe, or check/foot valve allowing water to move backward. | Have the system isolated and tested without dismantling equipment yourself. |
| Sand or fine silt appears | A well construction or screen problem, disturbed deposits, or changing pumping conditions. | Investigate the source before relying on a new filter. |
| Water changes color or smell | Minerals, treatment issues, plumbing components, or contamination. | Use appropriate laboratory testing; appearance cannot establish safety. |
| Breaker trips, humming or burning odor | An electrical or motor problem requiring professional attention. | Stop attempts to restart it. Keep clear of wet or damaged electrical parts. |
| Electricity use rises unexpectedly | Longer pump operation from a leak, delivery problem or equipment fault; other household loads can also contribute. | Compare pump behavior and household demand before blaming the motor. |
These are diagnostic clues, not a parts-replacement checklist. Pump design and well construction affect what each symptom means. [3–7, 9]
No water in the house with a well: what should you check first?
Check the scope of the outage, visible equipment status and signs of leakage. A dry faucet does not automatically mean the well has run dry or the pump needs replacement.
Confirm that the whole house is affected.
Compare two fixtures, including hot and cold. A single blocked faucet points toward a local restriction. Cold water working normally while several hot taps fail points toward the hot-water side. A widespread outage belongs on the well and incoming-supply checklist.
Look for a power interruption or displayed fault.
From a dry, safe location, note an outage, a visibly tripped breaker, or a control-panel message. Photograph accessible labels and displays for the technician. Leave electrical covers closed. Do not touch switch contacts, bypass a control or repeatedly reset a breaker.
Read the existing gauge, if it is safely visible.
Record the number and whether it changes. Zero pressure, a steady reading, or a falling reading are useful observations, but gauges can stick or fail. Do not assume a normal-looking dial proves that water is reaching the house.
Check for an obvious leak or unusual running.
Look at accessible pipes and the yard for new wet areas without entering a flooded crawlspace or well pit. A running pump with no delivery needs prompt attention. Use a known, safely accessible pump disconnect if you need to stop it; otherwise keep away and call.
Record what happened just before the outage.
A storm, power loss, filter change, plumbing repair, irrigation cycle or several overlapping showers can narrow the investigation. Pause optional water use while the cause is being assessed. Do not deliberately run the well until it sputters to “test” it.
Keep the diagnosis on the safe side of the cover.
Pressure switches, wiring and motor capacitors are professional troubleshooting territory. A jet pump that loses prime needs a different investigation from a submersible pump that has stopped. Manufacturer instructions also warn against running a pump dry. [3]
For a sudden outage, see our no-water well troubleshooting guide or request well pump repair. An active plumbing leak may also require answering service after hours; service scheduled during normal business hours.
How can you tell if your well is drying up?
Repeated loss of delivery during sustained use, followed by recovery, can indicate that the well is not supplying water fast enough. A falling water level is confirmed by measurement—not by how long a faucet runs.
The USGS explains that a well can effectively go dry when the water level drops below the pump intake. Groundwater levels respond to rainfall, recharge and pumping. They may recover, but the timing and extent depend on the aquifer and local conditions. [1]
Symptoms that can point toward a low-producing well
- Water fades during sustained demand. The problem follows laundry, irrigation or several people using water close together.
- Delivery improves after a pause. Record the pattern, but remember that a thermal or control fault can behave similarly.
- The system handles less than it used to. Normal household use now produces interruptions even though your habits have not changed.
- Air or sediment accompanies the loss of water. This adds a reason to investigate the well, but it does not confirm a dry well.
- Measured pumping levels are lower. Comparable historical and current measurements provide stronger evidence than faucet symptoms alone.
Why does a well keep running out of water?
There are two questions to separate: Has demand increased? and Has delivery decreased? A new irrigation schedule or a house full of guests can expose a supply limit that was already there. A leak can create demand you never intended. Declining groundwater, obstructed water-entry points or worn pumping equipment can reduce delivery. Several causes can occur together.
Tell the technician whether the problem is new, seasonal, tied to a particular appliance, or affecting nearby properties. A well that has always struggled with simultaneous use needs a different plan from one that suddenly cannot support a single shower.
Is 4 gallons per minute enough for a well?
It can be workable for some homes, but the number needs context. Well yield, water stored in the well, peak household demand, pump capacity and any properly designed storage system all matter. A brief bucket test at a hose measures delivery at that outlet; it does not establish the well's sustainable yield.
For example, if a well can sustainably supply 4 gallons per minute while the house uses 8, the 4-gallon-per-minute difference must come from usable storage. Over 15 minutes, that difference is 60 gallons. This is an illustrative water balance, not a storage-tank sizing recommendation. A pressure tank's labeled capacity is not the same as its usable drawdown.
A low-yield plan may include reducing simultaneous demand, repairing leaks, a properly designed potable-water storage arrangement, or work by a qualified well contractor. Installing a larger pump alone does not increase the aquifer's supply. Our well water system service page explains the equipment side of the system.
Three questions before replacing equipment
Is it the well, the pump or the pressure tank?
Is enough water reaching the intake?
Compare resting and pumping levels, yield and recovery. Review the well record and changes in demand.
Evidence: water levels + flow over time
Can the pump move that water?
Evaluate power, controls, pump performance and piping. Check for leaks, restrictions or loss of prime where applicable.
Evidence: equipment + delivery tests
Does the system cycle correctly?
Check usable tank drawdown, air charge, switching behavior and hidden demand. Interpret results for the installed design.
Evidence: pressure + cycle behavior
What are the signs of a failing well pump?
A pump that cannot build pressure, stops under load, runs unusually long, or produces little water needs investigation. Similar symptoms can come from the wiring, controls, a leak or the well supply.
Will not start
No pump operation
A power interruption, control fault or motor problem can stop delivery. Professional testing distinguishes a failed pump from a problem supplying or controlling it.
Runs without delivery
Little water or pressure
The pump may be worn or restricted, the water level may be too low, or piping may be leaking. Jet-pump systems also require attention to prime and suction-side air leaks.
Runs differently
New noise or longer cycles
Changes deserve attention even while water still flows. Note what the equipment does during ordinary use instead of forcing it through repeated starts.
Why does the well pump keep running?
First identify the control design. A conventional pump normally shuts off when demand is satisfied and the upper pressure setting is reached. Continuous operation can indicate ongoing water use, leakage or an inability to reach that setting. Some variable-speed systems run for longer periods by design, so a change from the system's normal behavior matters more than run time alone.
Does an older pump automatically need replacement?
No. Age and service history help with planning, but they do not locate the fault. Pump wear, water conditions, cycling frequency and installation all influence performance. Ask what testing supports replacement and whether a failed tank, pipe leak or control problem also needs correction.
For the next level of detail, use our well pump troubleshooting guide. When repair is needed, our well pump service page covers the practical next step.
Bad pressure tank symptoms: short cycling and surging water
A pump that switches on and off rapidly is a common reason to check the pressure tank. Low air charge or a damaged bladder or diaphragm can leave too little usable water between cycles. Leaks and control faults can also cause cycling problems.
The pressure tank supplies a limited amount of stored water and helps prevent the pump from starting for every small demand. It does not create groundwater or permanently make up for an undersized water supply. Amtrol lists rapid cycling and low pressure among symptoms that warrant a tank evaluation. [4, 5]
Can you tell by tapping the tank?
A tapping sound is not a dependable pass-or-fail test. Record rapid clicks, pressure swings or leaks, then have the tank checked correctly. Air-charge evaluation requires the appropriate procedure with water pressure relieved. Do not add air to a corroded or damaged tank, loosen fittings under pressure or adjust switches to hide a cycling problem.
Pressure pump with a tank versus a constant-pressure system
Conventional and variable-speed systems have different control and tank requirements. “Constant pressure” does not mean unlimited flow, and a compact tank is not automatically a missing or undersized part. Equipment must be matched to the pump, the controls and the well's capability.
Read more about well pressure tank replacement in coastal NC, including the symptoms to describe when you request service.
Why is water pressure low in a house with a well?
Low pressure can begin at the well or develop between the tank and a faucet. Compare where the problem occurs and how pressure behaves while water is being used.
Pressure, measured in psi, describes the force in the system. Flow, often measured in gallons per minute, describes the amount delivered. A normal gauge reading with every tap closed does not rule out a restriction that becomes obvious when someone showers.
| Pattern | Useful investigation |
|---|---|
| One faucet or shower is weak | Check the fixture, aerator, cartridge, connector and local supply valve before assuming a well failure. |
| Several hot taps are weak; cold is normal | Investigate heater connections, mixing components and hot-water piping. |
| Every fixture becomes weak under demand | Evaluate well and pump delivery, tank behavior, leaks and restrictions in shared equipment. |
| Pressure is better before the filter | Check filter condition, treatment operation, valves and pressure loss through that equipment. |
| Outside flow is better than inside | Identify where that hose bib branches off. It may bypass a restriction affecting the interior plumbing. |
| Pressure falls with no intentional use | Check for hidden demand, leakage and valves that should prevent backward flow. |
What is normal well water pressure?
Conventional systems often use an on/off pressure band such as 30/50 or 40/60 psi. The lower number starts the pump and the upper number stops it. The correct settings depend on the installed equipment and system design. Those examples are not instructions to adjust your switch. A low point in a normal cycle means something different from pressure that stays low while the pump cannot keep up. [3, 4]
For a fuller explanation of gauge readings and fixture-level restrictions, see warning signs of low water pressure in your home. A problem between the well equipment and the house may require main water line repair.
What are the symptoms of a clogged well screen?
Reduced well output, greater drawdown during pumping, longer recovery or recurring deposits can make a restricted screen worth investigating. These signs overlap with pump wear and declining groundwater, so a screen should not be blamed from symptoms alone.
Where a screen is installed, it admits water while limiting the entry of surrounding material. Mineral deposits, fine sediment and biological buildup can obstruct its openings. Some rock wells are completed without a screen, which is why the well construction record matters. [6, 8]
Where is the well screen located?
It is installed at the intended water-producing interval, generally below the solid casing in a screened well. Depth, length and its relationship to the pump vary. The top of the well, the pump intake and the screen are different parts of the system. Do not assume every well has the same arrangement.
How is a clogged screen diagnosed and cleaned?
A qualified well contractor reviews construction records and compares water levels, pump performance and flow. A downhole inspection may help assess the screen and casing. The contractor then decides whether rehabilitation is suitable and whether the well is structurally sound enough for the proposed method. [6, 7]
Screen cleaning, rehabilitation and replacement are specialist well work. Do not pour household drain cleaner, acid or a guessed chemical dose into a drinking-water well. The deposit, well materials, treatment method and return-to-service testing all affect the plan. Cleaning cannot guarantee recovery when the underlying problem is structural damage or limited groundwater.
Why is well water black, grey, yellow, muddy or full of sediment?
A new color, odor or particle problem is a reason to investigate and test. It may involve minerals, the well, plumbing or treatment equipment. Color alone cannot identify the contaminant or tell you whether the water is safe.
| What changed? | Possibilities to investigate | Helpful details to report |
|---|---|---|
| Black water or specks | Manganese deposits, other sediment, deteriorating components or treatment media. | Whole-house versus one fixture; hot versus cold; particles versus dissolved color. |
| Grey water or fine grey silt | Suspended material, disturbed deposits or air causing a cloudy appearance. | Whether particles settle, whether cloudiness clears, and whether pressure also changed. |
| Brown, rusty or muddy water | Iron, sediment, corrosion or water entering through a compromised well. | Recent heavy rain, flooding, repairs or a damaged cap. New intrusion needs prompt attention. |
| Yellow or tea-colored water | Iron, naturally occurring organic material such as tannins, or other water-quality changes. | Persistent versus temporary color, stains, and whether untreated water has the same appearance. |
| Rotten-egg odor | Hydrogen sulfide, sulfur bacteria or reactions involving the water heater. | Hot only, both hot and cold, or only water passing through treatment equipment. |
| Salty taste or new corrosion | Dissolved salts, treatment issues or another change requiring analysis. | Have chloride, sodium and other appropriate indicators evaluated; do not use taste as a test. |
| Slippery feel or visible slime | Softened water can feel slippery. Actual slime or deposits can have different causes, including biological buildup. | Separate the feel on your skin from material growing on fixtures or inside equipment. |
Manganese can cause dark staining, and sulfur-related problems can originate in the well, plumbing or heater. These possibilities still require confirmation for your property. [12, 15–17]
How do you get sediment out of well water?
First determine where the sediment enters. A filter may help capture particles, but persistent sand or silt can signal a well or equipment problem that needs correction. Document the appearance and recent work. Avoid repeatedly flushing a well that is already struggling to supply water. The appropriate filtration arrangement depends on particle characteristics, flow and the source of the problem.
How long does it take for well water to clear up?
There is no universal clearing time. A temporary disturbance after work is different from ongoing sediment entry or contamination. Clear-looking water is not proof that the well is safe. Get instructions for the specific work performed and the sampling needed before normal use resumes.
Explore brown, cloudy and sandy well water, iron and manganese in coastal NC wells, and rotten-egg odor in well water. If the issue appears only on the hot side, water heater service may be part of the investigation.
Is your well water safe to drink?
A functioning pump and clear water do not establish drinking-water safety. Have the water tested for the contaminants appropriate to your well and location.
CDC recommends testing private wells at least annually for total coliform bacteria, nitrates, total dissolved solids and pH. Use a state-certified laboratory and ask your local health department which additional tests are appropriate. Changes in taste, color or odor, flooding, nearby disturbances and well-system repairs are reasons to test again. [9]
Suspected contamination
Use a known safe source.
Stop drinking suspect well water. Use bottled water or another known safe source and obtain health-department advice about other uses. Boiling does not remove harmful chemicals. [10]
Flooded or damaged well
Have it assessed first.
Keep away from flooded pumps and electrical parts. A damaged or flooded well needs assessment, appropriate repairs, disinfection and testing before normal use resumes. [11]
Treatment selection
Match the equipment to the result.
A softener, sediment filter or drinking-water filter does not address every contaminant. Specify the problem to be treated, verify the system's capability, and maintain it as directed. [10]
Can bad well water make you sick?
Yes, contaminated water can cause illness even when it looks normal. New or recurring illness deserves medical advice; symptoms alone cannot identify the water as the cause. Tell your clinician that you use a private well and arrange appropriate water testing through your health department or a certified laboratory.
Wild Water's role: we service well pumps, pressure tanks, controls, connected plumbing and appropriate treatment equipment. We do not drill wells or provide laboratory water testing. Use your county health department or a certified laboratory for testing, and a qualified well contractor for drilling or structural well work.
Our well water system services can help address equipment and treatment needs identified through the investigation. The broader coastal North Carolina well water guide connects common quality and plumbing issues.
Well water problems in Onslow, Pender, New Hanover and Carteret counties
The property record is more useful than a county-wide assumption. Nearby homes can draw from different formations, use different equipment or receive water from a utility.
NC State Extension describes several Coastal Plain aquifer systems, including the surficial and Castle Hayne aquifers. Their water chemistry and vulnerability differ. NC DEQ also emphasizes that groundwater conditions and quality vary across the state. A town name alone does not establish your well depth, aquifer, yield or treatment needs. [13, 14]
Local details worth bringing to the service call
- For homes around Jacksonville and Richlands: bring the pump and tank history, well record and any changes in household or irrigation demand. Our Jacksonville and Richlands service pages explain local plumbing coverage.
- For Hampstead and surrounding Pender County properties: report when the change began and any nearby disturbance, drainage change or new water use. Timing helps guide the investigation without assuming construction caused the problem. See Hampstead plumbing service.
- For Wilmington-area and coastal properties: confirm which fixtures use the private well. Some properties have separate irrigation and household supplies. Report flooding, new salinity concerns and changes to treatment equipment.
- For Carteret County and Cedar Point: use the actual well record and laboratory results when comparing treatment or repair options. Check our Cedar Point service page for the local service connection.
What if a whole neighborhood starts having well failures?
Shared timing deserves a broader investigation, but it does not prove a shared cause. Compare dates, symptoms, power interruptions, well depths and recent test results. Groundwater levels can be affected by recharge and pumping, including withdrawals from other wells. Individual equipment faults can also occur at the same time. Contact the county health department about water-quality concerns and NC DEQ about relevant groundwater information. [1, 14]
What about salty coastal well water? Arrange testing rather than assuming that the pump has failed or that a deeper well will solve the problem. Treatment and well-construction decisions need site-specific water-quality and groundwater information. Do not deliberately taste suspect water.
Well system repairs, cost factors and next steps
Ask for the finding behind the recommendation: what failed, how it was checked, and what the repair is expected to restore.
- Pump or control fault
- The work may involve a control, wiring issue, pump repair or replacement. Access, pump depth and type, pipe condition and the extent of related work affect the scope. Start with well pump repair and replacement.
- Pressure tank or cycling problem
- Correct tank sizing, air charge, controls and leaks as appropriate. Replacing only the pump can leave the cycling cause in place. Our pressure tank guide explains what to discuss.
- Leaking or restricted supply line
- Locate the problem and identify the affected pipe before selecting a repair. Use our water line repair service for the connection between equipment and home.
- Low yield or well deterioration
- A qualified well contractor evaluates rehabilitation, construction changes or other supply options. Equipment upgrades must account for the water the well can actually provide.
- Water-quality problem
- Use laboratory results to select source correction, treatment or another water supply as appropriate. The plan should specify maintenance and follow-up testing.
How much does well pump or pressure tank repair cost?
A switch problem, a buried-line leak and a deep pump replacement are different jobs. A useful price follows a defined diagnosis and scope. Ask whether the proposal includes the pump or tank, controls, pipe and fittings, access work, startup checks and any required follow-up. Review our coastal NC well pump replacement cost guide for the factors to compare.
How do you help prevent future well failures?
Keep a well-system record.
Save the construction report, equipment model numbers, service invoices and laboratory results. Note normal pressure behavior and dates when it changes. Your well record may identify depth, casing, screen and original yield. [8]
Schedule testing and equipment checks.
Keep up with annual water testing, applicable manufacturer maintenance and professional inspection. Report new cycling, leakage or loss of delivery early.
Protect the wellhead.
Look for damage to visible casing or the cap without opening the well. Keep runoff directed away and chemicals away from the water source. Have defects addressed by the appropriate professional. [12]
Match water use to the supply.
Repair leaks, maintain treatment equipment and stagger high-demand uses if delivery is limited. Ask whether protective controls or an engineered storage arrangement suit the system.
Recheck after a problem or repair.
Confirm stable operation and follow the laboratory or health department's instructions for return-to-service sampling. A quiet pump is only one part of a complete water-supply check.
Well water system FAQs
How do I know if my well is drying up?
Loss of delivery during sustained use, recurring interruptions and measured declines in pumping water level can indicate a supply problem. Sputtering or sediment may accompany it. A pumping test and water-level measurements are needed because pump, control and piping faults can produce similar symptoms.
Why is there suddenly no water from my well?
Possible causes include a power interruption, control or motor fault, a leak, a blocked or closed supply, or inadequate water at the pump intake. Check whether all fixtures are affected and record safely visible equipment status. Do not open electrical controls or repeatedly reset breakers.
Why does well water stop and then come back?
The well may be recovering after demand drops, or a motor may be cooling and restarting after an overload. Controls can also interrupt delivery. A return of water does not identify the cause or prove the pump is healthy.
Can a dry well recover, and how long does it take?
Water levels can recover when recharge increases or pumping decreases, but there is no universal refill time. Well construction, groundwater conditions and demand all matter. A well contractor can measure recovery and evaluate whether the available supply is adequate.
Should I turn off a well pump that is running without water?
Running dry can damage a pump. If it continues to run without delivery, turn it off at a known, safely accessible disconnect and arrange service. Stay away from flooded, wet or damaged electrical equipment. Do not keep restarting it to see whether the problem clears.
What are the first signs of a bad well pump?
Reduced delivery, failure to build pressure, unusually long operation, new noise, electrical trips or stopping under load can be warning signs. They also occur with other system faults. Testing the pump, controls, water supply and piping helps avoid replacing the wrong part.
Is it my well pump or my pressure tank?
Rapid on-off cycling is a reason to check the tank and controls, while a pump that cannot deliver water needs a broader investigation. Neither pattern proves a single failed part. Usable tank drawdown, pressure behavior, leaks and pump performance should be evaluated together.
What are the symptoms of a clogged well screen?
Reduced output, greater drawdown during pumping, slower recovery or recurring deposits may point toward a restriction. Falling groundwater and pump problems can look similar. A qualified well contractor checks the well record, water levels and performance before recommending rehabilitation.
Where is a well screen located, and can I clean it myself?
A screen, where present, is installed at the intended water-producing interval, generally below the solid casing. Some wells have no screen. Cleaning requires an appropriate well assessment and specialist methods; do not put household chemicals or drain cleaner into the well.
Why is my well water black all of a sudden?
Dark water or particles can involve manganese, disturbed sediment, plumbing components or treatment equipment. The appearance does not confirm the cause or safety. Stop drinking water you suspect is contaminated and arrange appropriate testing and inspection.
What causes fine grey silt in well water?
Fine particles can enter or be disturbed within the well or connected equipment. Cloudiness from air can also look grey. Report settling particles, pressure changes and recent work. Persistent sediment deserves investigation of its source, not just repeated filter replacement.
Why does my well water feel slimy?
Softened water may feel slippery on skin. Visible slime on fixtures or equipment is a separate observation and can involve biological buildup or other deposits. The feel alone does not establish contamination; evaluate new deposits, odor or appearance changes through testing and inspection.
Is well water safe once the color clears?
Clear water can still contain harmful germs or chemicals. Follow the laboratory or health department’s guidance after a quality change, flood or repair. If contamination is suspected, use a known safe source until the necessary assessment, treatment and testing are complete.
Why is only my hot water pressure low?
If cold water delivery is normal at several fixtures, investigate the water heater connections, mixing components and hot-water piping. If just one fixture is affected, its cartridge, connector or local valve may be responsible. The well is not automatically the source of the problem.
Is a well producing 4 gallons per minute good enough?
It depends on sustainable yield, peak household demand, usable storage and the installed pump. Four gallons per minute may be workable for some homes with an appropriate system, but a short faucet-flow test cannot establish long-term well capacity.
How do I know whether my house uses well water?
Check closing documents, utility records and the well construction report, or ask the property owner and local water provider. A wellhead, pressure tank or pump controls can be clues. Some homes use separate supplies for irrigation and indoor plumbing, so confirm each connection.
How do I find my well depth and pump age?
Look for the well construction record, equipment labels, installation invoices and service records. Ask the original contractor or county health department about available records. Well depth is not the same as pump-setting depth, and a pump may have been replaced after the well was drilled.
What if a well fails inspection when I am selling a house?
Get the written findings and identify whether the issue involves water quality, yield, equipment or construction. Each requires a different response. Use the relevant qualified professional, obtain the requested follow-up testing and confirm the buyer’s or lender’s requirements before assuming one repair resolves everything.
How often should I test private well water?
CDC recommends annual testing for total coliform bacteria, nitrates, total dissolved solids and pH, with additional tests based on local concerns. Test again after relevant repairs, flooding or changes in water quality. Use a state-certified laboratory and consult your county health department.
