Local source context
Wellington Utilities publishes a 2025 drinking-water report and reports that its public system met applicable regulations. Those public-system findings do not establish the water quality at a private well.
Confirm whether each building uses municipal water or a private well. For larger Wellington properties, identify house, barn and irrigation lines separately before selecting equipment or discussing flow.

An under-sink reverse osmosis system serves a dedicated drinking and cooking tap. It normally uses pretreatment, a membrane and post-treatment components selected for the design. Actual reduction claims depend on the model and operating conditions; request documentation for the substance you care about. A total dissolved solids reading is not a complete safety test. RO is not the default answer to every household issue, and an under-sink unit does not treat showers, laundry or every fixture in the home.
Pressure, storage and access
A proposal should address incoming pressure, usable output, storage or tankless operation, drain connection and access for filter changes. Household use affects whether production and storage are sufficient. Ask about maintenance, membrane replacement and the water discharged during operation. If an existing softener or whole-home filter is present, explain that to the provider so the sequence is understood. Cabinet space, faucet arrangement and plumbing conditions can change installation scope and cost.
Whole-home RO is a different project
Whole-home reverse osmosis can involve pretreatment, storage, pumping and additional design considerations. It should not be presented as simply a larger under-sink unit. For a private well, source testing and professional evaluation are especially important. Request the reason a whole-home system is being proposed and compare it with targeted treatment for the measured problem. The appropriate design depends on the source, household demand, distribution materials and maintenance responsibilities; select it after an assessment rather than from a generic package list.
The Wellington assessment context
A domestic softener proposal should explain the demand it serves. Extending that assumption to additional buildings or high-volume uses can create pressure or regeneration problems. Ask for service flow, simultaneous demand and any cleaning or backwash requirements to be documented. If a barn or business process has a particular water target, describe that separately. Animal health or specialist process requirements should come from the appropriate qualified adviser, rather than an assumption that a drinking-water filter solves every use.
Before requesting reverse osmosis drinking-water systems
- Confirm your utility supplier or private-well source.
- Describe where the symptom occurs and any existing equipment.
- Provide recent test results, equipment photos and service history.
- Ask for equipment, installation, exclusions and maintenance in writing.
Questions about this service
Does under-sink RO solve hardness throughout the house?
No. It treats the water at its dedicated tap. Whole-home hardness control is a separate decision.
How often do filters need replacement?
Follow the actual model, usage and performance guidance. Ask for the schedule and consumable costs in the written proposal.
