Well Inspection and Flow Testing in Spokane, WA
Buying a rural property, selling one, or just curious how a well is holding up: one request connects you with a licensed local professional for a well inspection, a flow test, or both.
What a Well Inspection Covers
A well inspection is a physical and mechanical check of the well itself, separate from testing the water that comes out of it. A licensed inspector examines the wellhead for damage or improper sealing, checks the casing and cap for integrity and any visible signs of a contamination pathway, and confirms the pump and pressure system are functioning as expected. Where a well log is on file with Washington Ecology, the inspector reviews it for construction depth, casing details, and original yield, comparing that record against what the well is doing today. A well with no findings still gets documented, since a clean report has real value at the time of a home sale or a routine ownership check.
What a Flow Test Measures and Why It Matters
A flow test measures how many gallons per minute a well can sustainably produce under real pumping conditions, not just whether water comes out when a faucet opens. That number matters most in two situations: before buying a rural property, where an unknown well's output is a real unknown, and before adding fixtures or appliances that increase household water demand beyond what the current system was sized for. A well that tests low on flow is not automatically a problem; it may still be entirely adequate for a typical single-family household. It is simply information worth having before a purchase closes or a renovation begins, not something to discover after the fact.
Well Inspections for Home Buyers and Sellers
Washington does not have a single statewide law requiring a well inspection before every home sale involving a private well. In practice, many lenders and purchase agreements require one anyway, particularly for rural financing where a functioning, adequate water supply is part of what the lender is underwriting. Requirements vary by lender, by loan type, and by the specific purchase agreement, so a buyer or seller should check the actual contract terms rather than assume a rule applies statewide. Either way, an inspection and flow test done before closing gives both sides a documented, third-party record of the well's actual condition at the time of sale.
Water Quality Testing
Water quality testing is a separate lab process from the physical well inspection, checking what is actually in the water rather than the condition of the well itself. Washington Ecology and most local health districts recommend testing private well water annually for bacteria, since bacterial contamination can appear and disappear between seasons, and every few years for nitrates and other common regional contaminants. Testing more often makes sense after any repair work near the wellhead, after a flood or heavy runoff event, or if there is a known contamination risk nearby, such as an old septic system or agricultural runoff upstream of the property.
What Well Inspection and Flow Testing Cost in Spokane
A standard well inspection with a flow test in the Spokane area commonly runs a few hundred dollars, with water quality lab testing priced separately depending on how many contaminants are tested for. Exact pricing depends on well accessibility, how deep the well runs, and how many separate tests are requested. See the cost guide for how inspection pricing compares to drilling and pump costs.

Inspection Questions, Answered Straight
What does a well inspection actually check?
A well inspection typically covers the wellhead condition, casing and cap integrity, visible signs of contamination risk, pump and pressure system function, and a review of the well log if one is on file with Washington Ecology. It is a physical and mechanical check, separate from a water quality lab test.
What is a flow test and why does it matter?
A flow test measures how many gallons per minute a well can sustainably produce, which matters most before buying a rural property or adding fixtures that increase household water demand. A well that tests low on flow may still be adequate for typical single-family use, but it is worth knowing in advance.
Do I need a well inspection to sell a home with a well in Washington?
Washington does not have a single statewide law requiring a well inspection before every home sale, but many lenders and purchase agreements require one anyway, especially for rural financing. Requirements vary by lender and by transaction, so check your specific purchase agreement rather than assuming one way or the other.
How much does a well inspection or flow test cost in Spokane?
A standard well inspection with a flow test in the Spokane area commonly runs a few hundred dollars, with water quality lab testing as a separate added cost depending on how many contaminants are tested for. Exact pricing depends on well accessibility and how many tests are requested.
How often should well water be tested for quality?
Washington Ecology and most local health districts recommend testing private well water annually for bacteria, and every few years for nitrates and other common contaminants, more often if there is a known local risk or a noticeable change in taste, smell, or color. Testing after any repair work is also a good practice.
