Comprehensive water quality testing and GPM flow assessments for homeowners, buyers, and lenders.
A flow test measures how many gallons per minute (GPM) your well can consistently produce. This is essential for real estate transactions, new construction, and understanding your well's capacity.
We run your well continuously for 4 hours while measuring multiple parameters at regular intervals throughout the test:
Some companies offer "quick" 30-minute or 1-hour flow tests. These shorter tests are unreliable because they hide problems that only appear under sustained pumping. A well might produce 15 GPM for the first hour but drop to 3 GPM by hour three as the water table draws down. Short tests give sellers a false sense of security and buyers a nasty surprise after they move in. The 4-hour standard exists for a reason — it reveals your well's true sustained capacity.
After the test, you receive a detailed written report showing GPM measurements throughout the 4-hour period. This report is accepted by lenders, real estate agents, and inspectors across the Spokane area.
Knowing what's in your water matters. We collect samples from your well and send them to certified labs for thorough analysis.
The most common and most important test. Detects harmful bacteria that can cause illness. Required for most real estate transactions.
Common in agricultural areas. High levels are dangerous, especially for infants. Standard requirement for home sales.
Naturally occurring in some Spokane-area wells. Lab testing determines if levels are within safe limits.
Older well components and natural geology can introduce lead and other heavy metals into your water. Lab analysis confirms whether levels are within EPA safe drinking water limits.
Comprehensive testing including pH, hardness, iron, manganese, and other parameters. Iron staining, hard water scale, and low pH (acidic water) are common in Spokane-area wells and affect both water quality and plumbing longevity.
While home test kits are available at hardware stores, there are important reasons to use a professional sampling service for any testing that matters — especially real estate transactions:
Buying or selling a home with a well? We handle all the testing your transaction needs:
Call us with the property address and loan type. We'll coordinate timing with your closing schedule — we know deadlines matter.
We visit the property, conduct the flow test, and collect water samples. The well system gets a visual inspection too.
Water samples go to a state-certified lab. Results typically come back within 5-7 business days.
You get a complete report package ready for your lender, including flow test results and lab analysis certificates.
Different loan programs have different requirements. Here's what you need to know:
FHA requires a water quality test (bacteria and nitrates at minimum) and sufficient flow for the property. The well must meet FHA distance requirements from septic systems and property lines.
VA loans require water potability testing and may require a flow test depending on the appraiser's assessment. We provide VA-compliant testing packages.
USDA rural development loans require both water quality testing and a flow test. The well must demonstrate adequate capacity for the home. We handle USDA-compliant testing regularly.
Requirements vary by lender, but most want at least a bacteria test. Your real estate agent or lender will let you know — and we can do whatever's needed.
Whether you need a flow test for a real estate transaction, water quality testing for peace of mind, or a complete FHA/VA/USDA loan testing package, we handle it all. We work with your timeline and deliver lender-ready reports that are accepted throughout the Spokane area.
