If you’re buying a home with a private well, scheduling a well inspection is essential to ensure water safety and system performance. A well inspection checks the safety, quality, and reliability of your water system — including flow rate, pump function, and potential contaminants.

What is a Well Inspection?

A well inspection is a professional assessment of a private well's condition, water safety, and performance. It typically includes an examination of the well pump, pressure tank, electrical components, water yield (flow rate), and contamination testing (coliform bacteria, arsenic and nitrates) to ensure the water is safe for household use.

Well inspections are especially important when purchasing a home not connected to a public water supply, as the property's water source is entirely dependent on the functionality and safety of a private well. 

Why Well Inspections Matter for Home Purchases

In the context of a real estate transaction, a well inspection is usually required before closing. Most counties in Washington State require the seller to provide a water-sampling results to ensure the water is safe to drink. While important, this doesn't always take into account the functionality and safety of the well as a whole. Home buyers should always conduct a full well inspection before closing to ensure there are no additional issues. 

Here are additional factors to consider: 

Lender Requirements

Many mortgage lenders require a well inspection and water quality testing before approving financing for homes with private wells. Water must be tested for contaminants like coliform bacteria, nitrates, and arsenic, which are virtually impossible to detect through smell or water appearance.

General Inspection Limitations

Private wells aren't included in general home inspections, which is why it's essential to request a well inspection through a certified company. 

Impact on Closing

If a well fails to meet safety standards or cannot produce adequate flow, the buyer may need to negotiate repairs, filtration systems, or replacement prior to closing. 

Pro Tip for Sellers: Washington State recommends you have a private well inspected annually. Lining up this annual inspection right before the house goes on the market can result in a faster sale, and provide more peace of mind for buyers. 

What's Included in a Well Inspection?

A certified well inspection covers both the mechanical function and water quality of the system. At Ralph's Pump and Well, we provide comprehensive assessments to ensure your well is functional and meets real estate requirements.

• Visual and Mechanical Inspection: We examine the well head, visible plumbing, and water filtration components to identify signs of wear, damage, or improper installation.
  
  
• Water Quality Testing: Water samples are tested for common contaminants such as bacteria (including coliform), nitrates, and arsenic — helping ensure the water is safe for drinking and household use.
  
  
• System Flow and Yield Test: We measure the flow rate and system output to confirm that the well provides a consistent and sufficient water supply for the household’s needs.
  
  
• Water Level Monitoring: We check static and dynamic water levels before and during pumping to evaluate well recovery time and sustainability.
  
  
• Component Performance Testing: This includes a detailed check of the pump motor, pressure tank, and pressure switch — including amp load, grounding, and voltage levels — to ensure all critical components are operating within safe and efficient parameters.
  
  
• General Water Quality Observation: We note any visible or sensory issues with the water, such as unusual color, odor, or cloudiness, which may indicate the presence of sediment, iron, or other problems.
  
  
• Well Age and Lifespan Assessment: We review available records or estimate the well’s age and condition to help you understand its remaining lifespan and plan for future maintenance or replacement.

What Happens if the Well Fails the Inspection? 

If your water is contaminated, you may need a water treatment and conditioning filtration system. While these can be big investments, they prolong the lifespan of your well and ensure quality drinking water. 

At Ralph's Pump, we aim to make the process as clear and stress-free as possible by providing:

• A detailed inspection report with findings clearly outlined
• Upfront, transparent pricing for any recommended repairs
• Inspection documentation that can be shared with your real estate agent or lender
• Flexible payment options for repairs, available for qualifying individuals

By addressing any issues promptly and knowing exactly what repairs or upgrades are needed, you can protect both your well system and your home’s water quality.

Frequently Asked Questions

What are the local and state requirements for well inspections?

Washington State recommends annual well inspections, along with water quality testing prior to selling. The Snohomish County Department of Health outlines instances when well water testing is recommended outside of an annual inspection, specifically when considering contamination from nitrates, arsenic, or coliform bacteria. Learn more about these conditions here.

Who pays for repairs? 

Responsibility for repairs vary. Whether the buyer or seller is responsible for repairs will depend on the negotiated terms of the sale. Some buyers may choose to accept responsibility for minor issues, while others may expect the seller to complete repairs before closing.

Does a general home inspection include the well? 

No, general home inspections do not include well water testing. The seller needs to request a separate well inspection from a certified company. 

How important is a well inspection for a home purchase? 

A well inspection is essential when purchasing a home with a private well. Water testing is especially important as common contaminants like arsenic, coliform bacteria, and nitrates are virtually undetectable otherwise. Without an inspection, buyers risk unexpected repairs, poor water quality, or costly pump replacements after moving in. A professional evaluation provides confidence in the home’s water supply and can help with negotiating repairs or closing costs.
