Equipment
- Stages: sediment, carbon, membrane, post-filter, alkaline.
- Tank or tankless/compact design.
- Certification claims under NSF/ANSI 58 that match your goals.
See tankless vs. tank RO.
Living Water's alkaline RO includes a remineralization stage after the membrane; it is part of both the equipment and the filter schedule, so it should appear on the quote.
Installation
| Factor | Effect |
|---|---|
| Faucet hole | Existing hole vs. drilling stone or quartz |
| Drain | Ease of connection |
| Fridge or ice maker | Extra tubing and fittings |
| Pressure | Booster pump if pressure is low |
| Cabinet space | Compact unit for tight cabinets |
Low pressure is the most common surprise. If your home's pressure is low, a booster pump may be recommended, and the quote should explain why with the reading Jorge took.
Condo and townhome associations sometimes set rules for under-sink work or countertop drilling. Check before you schedule, and Jorge will work within them.
Running costs
- Pre-filter, post-filter and alkaline cartridge intervals.
- Membrane life under your water and use.
- Water sent to drain during production.
- Optional service visits.
On WASD chloramine water, the carbon pre-filter protects the membrane, so changing it on time saves money later. See RO operating costs.
A cheap system with hard-to-find filters, no certification listing, or no local service can cost more over its life than one with a higher starting price. Ask how filters are supplied and who changes them.
Filter intervals depend on how much water your household uses; a family of five cooking at home every day will change pre-filters sooner than a couple who mostly eat out. Jorge sets the schedule from your use, not a generic sticker.
Fair comparison
Count your monthly bottled water purchases and compare with the filter schedule. Our bottled water vs. RO calculator helps.
Count the time too: carrying cases, storing them, recycling bottles. For a household drinking several liters a day, those trips add up.
Quote checklist
- Model and certification listing.
- Itemized labor and parts.
- Filter part numbers and intervals.
- Warranty.
- Service contact.
Living Water offers financing through its financing partners; you apply with a credit application, and a co-applicant can apply with you.
Ask too whether the quote covers the faucet finish you want, the fridge connection, and a dissolved-solids test after installation to confirm performance.

Renters can often install RO with landlord approval, since it fits under the sink and can be removed when you move.
