Short answer: a quote is the sum of equipment (type, size, tank construction), installation (how much plumbing, drain and electrical work your home needs), and the terms that come with it (what the limited warranty covers). Ownership adds consumables (salt or potassium, RO cartridges), occasional service, and the small amounts of water and electricity the equipment uses. Compare proposals line by line on those items, not on the headline.
What drives the equipment price
- Type of system. A point-of-use RO is a different scale of purchase from a whole-house combination system, and a home that needs both is buying two systems.
- Sizing. Resin capacity and flow rating follow measured hardness, household size and the number of bathrooms. A larger home with very hard water needs more resin and a higher-flow valve than a two-person condo with moderately hard water.
- Tank construction. Among the Puronics C-series, the Defender (lined fiberglass), Hydronex (lined composite with stainless cover) and Terminator (316L stainless tank) treat water identically; tank material and the associated warranty scope are what you are choosing between.
- Additional equipment the test reveals. Iron filtration, neutralization for low pH, sediment filtration or ultraviolet disinfection on a well each add a stage. These are findings-driven, and a proposal should tie each one to a test result.
What drives the installation price
- Plumbing access. An open basement with the main line, a drain and an outlet within a few feet is the simplest case. Finished spaces, crawl spaces, long runs to a drain, or older pipe that needs repair add labor and materials.
- Drain and electrical. If there is no suitable drain or grounded outlet, one has to be added.
- Bypass and re-routing. A bypass valve is standard; plumbing outdoor spigots around the system so irrigation does not use treated water is an option that adds some work.
- Reverse osmosis specifics. Drilling a faucet hole in a stone countertop, running a line to the refrigerator, or working in a crowded sink cabinet each affect the time.
What ownership involves
| Item | Whole-house softener/filter combination | Reverse osmosis |
|---|---|---|
| Consumables | Softener salt or potassium chloride, bought in bags; quantity depends on hardness and water use | Pre- and post-filter cartridges on the manual’s schedule; membrane less often |
| Water | Backwash and regeneration water sent to drain on a demand-initiated schedule | Reject water to drain during production |
| Electricity | Small amount for the control valve | None |
| Media | Clearess media: no scheduled cartridge changes per Puronics; limited lifetime warranty on the media; life rated in gallons and shortened by high disinfectant levels | Not applicable |
| Service | Occasional valve service over the life of the system; resin eventually wears | Annual or as-needed sanitizing and cartridge changes |
| Your time | Checking the salt level; keeping the area accessible | A quick twist to change Easy Change cartridges |
The manufacturer's disclaimer applies to every system: operational maintenance and replacement requirements are essential for the product to perform as advertised.
Warranty scope
Every system we sell comes with a written limited warranty from Puronics. "Limited" means it has conditions and exclusions, and the document, not a summary, governs. Puronics states the ChloroShield Clearess media carries a limited lifetime warranty on the C-series systems, and the owner's product information describes the Terminator iGen C as carrying a limited lifetime warranty on the entire system; we confirm the written terms for each model with the quote. Ask any installer the same four questions: what is covered, for how long, whether labor is included, and what voids it.
Why there are no numbers here
This guide gives no price ranges, savings estimates, payback periods or financing terms because we cannot know them for your house without the assessment, and because invented numbers mislead. Puronics itself notes that actual savings depend on your particular spending habits and usage levels. The written quote you receive after the visit is specific and itemized.
How to compare proposals
- Make sure they are sized the same way. Two quotes for "a softener" can be for very different resin capacities and flow ratings. Ask for the model, the capacity and the valve.
- Map each line item to a test result. A proposal should be able to say which finding each piece of equipment responds to.
- Separate equipment from installation. A low headline price with an unspecified installation scope is not comparable to an itemized one.
- Read the certifications, not the adjectives. "Certified to NSF/ANSI 44 for hardness, barium and radium" is comparable; "removes everything" is not.
- Read the warranty document. Limited lifetime on which component, with what conditions.
- Ask about consumables and service in writing: what you will buy, how often, and who services the system.
- Ask who installs and whether the same company stands behind both equipment and installation.
Our quotes are built to be compared this way. If another proposal is better for your home, we would rather you choose it than buy the wrong system from us.
