What should I have inspected on a private well before buying?
Reviewed August 2026 by Shannon Miles Group
A well system inspection evaluates the visible condition of the well, wellhead, pump, pressure tank, electrical components, and available production records. It is different from water quality testing. A qualified well professional should perform the inspection. Do not attempt DIY electrical or mechanical inspection yourself. The well system evaluation tells you about the equipment's condition and expected lifespan, while water testing tells you about the water itself.
What a well system inspection covers.
A well system inspection is a separate evaluation from water quality testing. It focuses on the physical condition and operation of the well and its equipment. A qualified well professional can assess the system's condition and provide an objective opinion on its remaining lifespan. This is a critical step in due diligence when buying a property with a private well.
What the inspection covers
Visible well condition
The inspector examines the well casing, the well cap or seal, and the ground surface around the well. The wellhead should be properly sealed and protected from surface water runoff. The casing should be in good condition with no visible damage.
Wellhead and seal
The wellhead should be at least 12 inches above the ground surface and properly sealed to prevent contamination from surface water, insects, and debris. A damaged seal is a contamination risk.
Pump
The inspector identifies the type of pump (submersible or jet pump) and assesses its age, condition, and performance. Pump age is important because pumps typically last 10 to 15 years. The inspector can check for proper operation and signs of wear.
Pressure tank and system
The pressure tank maintains consistent water pressure in the home. The inspector checks the tank for proper air charge, signs of waterlogging, and overall condition. Pressure tanks typically last 10 to 20 years.
Electrical components
The inspector checks the electrical connections, wiring, and control box for the pump. This is a professional evaluation, not a DIY task. Improper electrical work can be dangerous and cause equipment failure.
Leaks and equipment condition
The inspector looks for visible leaks at the pump, pressure tank, and plumbing connections. Leaks can indicate worn seals, corrosion, or impending failure.
Production and flow information
The inspector reviews any available well driller's report for the well's original depth, casing diameter, and flow rate. If the well has a flow meter, historical production data can help assess whether the well's yield has changed over time.
Available records
The well driller's report, water testing results, and maintenance records provide valuable history. A well with complete records is easier to evaluate than one with no documentation.
Location relative to contamination sources
The inspector considers the well's location relative to the septic drain field, livestock areas, chemical storage, and other potential contamination sources. Minimum separation distances are regulated in Texas.
A well system inspection gives you a clear picture of the equipment's condition and expected lifespan. Combined with water quality testing and a flow test, you get a complete picture of the well's health. For water quality and quantity testing, see Should I have well water tested before buying a home?
Do not attempt to perform electrical or mechanical inspection of a well system yourself. Qualified well professionals have the training and equipment to evaluate the system safely and accurately. A professional inspection is a worthwhile investment in your due diligence.
Well inspections in Northeast Texas.
Qualified well professionals serve the Northeast Texas area and can evaluate well systems for buyers. The Texas Well Owner Network, operated by the Texas A&M AgriLife Extension Service, is an excellent resource for finding guidance on well maintenance and evaluation.
Well ages vary widely across the region. Some properties have wells that are decades old, while newer homes may have wells drilled within the last few years. Older wells may have been drilled to different standards and may not have the same level of protection against surface contamination as modern wells.
If you are buying a property with a well, include a well system inspection in your due diligence period. The report can help you understand the equipment's condition and plan for future maintenance or replacement.
Key factors for well inspections.
- Well inspection is separate from water testing. The well system evaluation covers equipment condition. Water testing covers the water itself. Both are needed.
- Hire a qualified well professional. A licensed well driller or pump installer has the expertise to evaluate the system. Do not attempt DIY evaluation.
- Ask for records. The well driller's report, water tests, and maintenance history help the inspector assess the well's condition and history.
- Check the wellhead location. The well should be located a safe distance from septic systems, livestock areas, and chemical storage. Texas rules specify minimum separation distances.
- Plan for equipment lifespan. Pumps, pressure tanks, and electrical components have finite lifespans. Budget for future replacement.
- Use the inspection in negotiations. If the inspection reveals significant issues, you can negotiate repairs or a credit with the seller before closing.
