Reverse Osmosis Drinking Water Systems
Reverse osmosis may be useful at a drinking-water tap, but the right choice depends on what the water contains. Request a referral to compare documented treatment options rather than broad 'pure water' claims.
What an under-sink system is intended to do
Reverse osmosis is a point-of-use treatment option that can reduce certain dissolved substances using a membrane-based process. It is commonly considered for drinking and cooking water rather than every household use. Virginia Tech discusses reverse osmosis among household treatment options and as a possible way to reduce sodium at a drinking tap. Performance depends on the specific equipment and conditions, so ask for documentation for each contaminant you want to address. Virginia Tech guidance. Virginia Tech guidance.
Decide whether your goal is taste, a particular laboratory result, or drinking-water treatment alongside a softener. A low total dissolved solids reading is not proof that every contaminant has been removed. If the source has a bacteria concern, address that with qualified advice and the appropriate treatment plan; do not assume any under-sink product is suitable for an unsafe source. Virginia Tech guidance.
Ask about source water and claimed reductions
Bring a source-water report and ask the provider to check the unit's operating limits. Discuss hardness, iron, manganese, pressure, and any other conditions that affect the proposed design or pretreatment. Request the manufacturer's performance information for the actual model, including any claimed certifications and their scope. This website does not certify equipment or represent that an independent installer holds any particular product certification. Virginia Tech guidance.
If lead is the concern, Virginia Tech notes that plumbing corrosion can be a source and discusses treatment at a drinking tap alongside addressing corrosivity. Have the provider explain whether the plan treats the cause, the exposure point, or both. Keep the laboratory's collection instructions, because a sample for metals from household plumbing may not answer the same question as one collected to characterize untreated well water. Virginia Tech guidance.
Make room for ongoing operation
Ask how much space is required for the specific model, whether it uses a storage tank, where the faucet will be mounted, and how reject water will be drained. Request the expected production and recovery information rather than comparing systems only by the number of filter stages. Confirm whether the installation includes the plumbing changes needed at your sink and whether any refrigerator connection is in scope. Virginia Tech guidance.
Get a written schedule for prefilters, postfilters, membrane checks or replacement, and sanitation according to the model's instructions. Ask which tasks are homeowner maintenance and which require service. Include replacement parts and follow-up sampling in your comparison of proposals. Do not keep using an overdue filter merely because the water still tastes acceptable; taste does not verify removal of the substance that led you to seek treatment. Virginia Tech guidance.
What to gather before a provider visit
Write down when the problem began, whether it affects hot water, cold water, or both, and which taps are involved. Note any recent plumbing work, filter changes, flooding, or long periods when the home was unoccupied. Take photos of stains and equipment labels. Bring previous test reports, even if they look normal, and ask the provider to distinguish untreated well water from water already passing through treatment. This is a practical way to make the appointment specific to your home rather than a general equipment demonstration.
Ask which measurements are included in the free in-home screening and which require a separate laboratory sample. A screening for hardness, pH, or iron is not a certified bacteria report and does not establish that water is safe for every use. Request written results with units, sampling location, and collection date. For laboratory samples, follow the laboratory's bottle, handling, and delivery instructions rather than collecting water in a household container. Virginia Tech testing guidance.
Compare a complete plan, not just a piece of equipment
Request an itemized written quote tied to your test results. Ask what the proposed equipment treats, what it does not treat, and how its performance will be checked after installation. Include installation changes, maintenance access, drain requirements, electrical work where needed, replacement supplies, service visits, and warranty exclusions in that conversation. Review what affects water treatment cost before comparing proposals. A lower equipment-only figure is not a complete comparison if another proposal includes work the first one leaves out.
Ask who will actually perform the work and who is responsible for future service. Virginia law requires contractor licensing for contracting work, including well construction, and separately addresses certified water well systems providers for well drilling, installation, maintenance, and repair, subject to statutory exceptions. Verify the credentials applicable to the specific scope; do not assume a salesperson's title covers well work. Lynchburg Well Water is not a contractor and does not issue licenses or certify providers. Va. Code § 54.1-1103. Va. Code § 54.1-1129.
Keep records and check the result
Before approving a proposal, ask the provider to explain the startup procedure, how you will know the system is operating, and which checks remain your responsibility. Keep the written test results, equipment model numbers, service instructions, and any follow-up sampling plan together. Record later changes in taste, odor, appearance, or water pressure rather than assuming that installed equipment will handle every future issue.

Our referral request is free and does not obligate you to buy treatment. Appointment coverage, screening scope, laboratory fees, and any installation quote must be confirmed directly with the independent provider. Your request is stored for referral handling; an operator email notification is attempted when email is configured, but delivery is not guaranteed. You may leave the optional automated-call and text consent unchecked and still submit. This website is not an emergency response service or a substitute for health-department advice about a suspected unsafe supply.
Frequently asked questions
Does a free in-home screening prove my water is safe?
No. Confirm what the provider includes. A screening is not a substitute for certified laboratory bacteria testing or a complete assessment of all possible contaminants. Laboratory testing may have a separate charge. Virginia Tech guidance.
