A private well supplies more than water at a faucet: the pump, pressure tank, and controls need to work together. My well flow testing service helps buyers and homeowners understand how that system performs during a measured test. I’m Darren Buckley, and I founded High Definition Home Inspections in 2013. I hold Washington home inspector license 966, am an InterNACHI Certified Professional Inspector, and hold an IAC2 credential. I explain the observed findings without promising future performance.
A closer look at the system
What my well testing includes
- Well record and permit search
- I search for available well records and permit information to add context, without guaranteeing complete records or compliance.
- 60-minute flow and pressure test
- I use a pressure gauge and a GPM (gallons-per-minute) meter to document delivery during a 60-minute flow test.
- Pump performance check
- I check pump performance using a clamp meter and consider the observations alongside the flow and pressure readings.
- Pressure tank inspection
- I inspect the pressure tank, including an air pressure check, as part of assessing system operation.
- Visual well head and electrical inspection
- I visually inspect the accessible well head and electrical components; concealed parts and inaccessible components remain outside that visual assessment.
Start with the available well history
I include a well record and permit search to look for information associated with the property’s well. Available records can add context to the field observations, but an older record may be incomplete or difficult to match to the current installation. A search does not guarantee that every record will be located or establish permit approval or compliance.
If you have a well log, permit paperwork, or previous test report, share it before the appointment. For a purchase, ask the seller or agent about known well work and any specific documentation your lender needs.
Measure flow and pressure over 60 minutes
I perform a 60-minute flow test using a pressure gauge and a GPM (gallons-per-minute) meter. Measuring both helps me describe water delivery and pressure response during the test, rather than relying on how a faucet feels when first opened. Readings over that period can show whether observed delivery remains steady or changes as the system operates.
There is no single GPM number that answers every household’s needs. I discuss the readings in the context of the property and intended use. This timed test documents performance under the conditions present; it does not establish year-round yield or reproduce every pattern of household demand.
Check the equipment supporting water delivery
I check pump performance using a clamp meter, inspect the pressure tank including an air pressure check, and visually inspect the accessible well head and electrical components. These checks help put the flow and pressure readings in context and identify observed conditions that may warrant attention.
The visual inspection is not an examination of every electrical component or concealed well part. I cannot see the entire underground installation or predict remaining pump life. If an observed condition calls for deeper evaluation, I explain why follow-up with an appropriate well professional or electrician is worth considering.
Plan access before the appointment
Tell me whether you are buying the home, investigating a change in water delivery, or documenting the system’s current condition. For a transaction, share the inspection deadline and coordinate with the owner or agent. I can discuss access to the well head, pressure tank, controls, power, and a suitable hose connection before the visit.
Mention locked areas, known operating problems, and any records available. Please leave equipment adjustments to the appropriate professional. If access or operating conditions limit testing, I document that limitation rather than treating an incomplete check as a complete assessment.
Use the findings for your next decision
My written findings document observed performance, the components checked, and relevant limitations. For a buyer, that gives you information to discuss with the seller and decide whether further evaluation is needed. For a homeowner, it provides a record of current conditions when considering a concern or planning follow-up.
Mechanical testing and water-quality laboratory testing answer different questions. A system can deliver water consistently without that measurement establishing its quality. Likewise, a laboratory result does not tell you how the pump and tank perform. I keep those scopes separate so you know what the appointment covers.
Questions before you book
Is well water lab testing included?
No. Well water lab testing is an optional add-on. I discuss the sampling scope with you before arranging it, including the question you want answered and any requirements provided by a lender or other requesting party.
Does a 60-minute test guarantee enough water all year?
No. It records delivery during that test. Seasonal conditions and household demand can differ from the appointment conditions, so I do not use one test to guarantee year-round supply or future system performance.
Can the inspection tell me how long the pump will last?
I can document observed pump performance and explain concerns, but I cannot predict remaining service life. A clamp-meter check is one part of the assessment, not a guarantee that every internal or electrical condition has been found.
Will a permit search confirm the well is compliant?
Not by itself. I report the available record information without treating a search as regulatory approval. If compliance or a transaction requirement is your concern, confirm the necessary documentation with the responsible agency or requesting party.
I serve Kitsap and Pierce Counties, including Port Orchard, Gig Harbor, Bremerton, Silverdale, Tacoma, and Poulsbo, with service across Puget Sound and the Olympic Peninsula. Contact me with the property location, your concern, and your timing so I can help you plan a well flow testing appointment.
