Every RO purifier has a yearly running cost beyond its purchase price — and most buyers only discover it one repair bill at a time. This guide gives the honest yearly picture for Ahmedabad and Gandhinagar using Nyasa Enterprise's actual prices: what routine care costs, what membrane and pump work costs, how an AMC compares with pay-per-visit care, and what pushes the yearly figure up. No fixed membrane or pump price is promised here, because those prices depend on your purifier's model and capacity and are quoted only after diagnosis.
What Yearly RO Maintenance Is Made Of
| Item | How often | Nyasa price |
|---|---|---|
| Routine service (cleaning, checks, tank cleaning, TDS test) | Usually twice a year | ₹299 per service |
| Filter change (sediment, carbon) | Every 6 to 12 months | ₹199 onwards per filter |
| Membrane replacement | Every 1 to 2 years | Quoted after diagnosis |
| Pump / motor repair or replacement | Only when faulty | Quoted after diagnosis |
| Doorstep visit charge | Per visit, as applicable | ₹150 |
Frequencies are usual ranges, not fixed dates — borewell water and high-TDS supply wear filters and membranes out faster, while a pre-filter in good shape protects the membrane behind it. Our RO filter replacement price guide and membrane replacement signs guide cover those two items in detail.
Worked Example: A Routine Year
Take a typical family purifier on municipal water in Ahmedabad. A routine year usually means 2 services at ₹299 each (₹598) and 1 to 2 filter changes from ₹199 each (₹199 to ₹398). That puts routine service and filters at about ₹800 to ₹1,000 a year — before any membrane or pump work, and excluding the ₹150 per-visit charge where it applies. A membrane year costs more, because the membrane itself is added to the same routine bill; a pump fault year costs more again. The honest point is this: the yearly figure is not one number. It is routine care (predictable, roughly ₹800 to ₹1,000) plus occasional parts (quoted only after testing).
Pay-Per-Visit vs AMC: An Honest Comparison
| Pay per visit | AMC plan | |
|---|---|---|
| Yearly price | Routine care about ₹800 to ₹1,000, plus parts as needed | ₹1,999 / ₹2,999 / ₹3,999 per year |
| What it suits | Low-usage homes, newer purifiers | Homes that want scheduled care in one plan for the year |
| Booking | Book each visit separately | One plan covers the year's scheduled care |
An AMC is not automatically cheaper than pay-per-visit routine care — its value is scheduled care in a single yearly plan, without booking each visit separately. Which one suits you depends on your usage, your water quality, and how old the purifier is. Our repair-vs-AMC guide and RO AMC plans guide compare the two routes in full, including what to ask before choosing a plan.
What Makes Yearly Cost Go Up
- Hard or borewell water. Faster filter and membrane wear means more frequent changes — the single biggest cost driver.
- Skipped service. A choked filter strains the pump and shortens membrane life, turning a ₹199 filter change into a much larger repair.
- Unneeded part changes. Parts changed without a TDS reading or a shown old part add cost without fixing anything. Diagnosis first is the protection: no part is fitted before you approve an itemised quote.
- Emergency callouts. A priority visit for an urgent breakdown is ₹399, against the standard ₹150 visit charge — regular service prevents most emergencies.
How to Keep Yearly Cost Down
- Change filters on schedule — 6 to 12 months for pre-filters and carbon filters — instead of waiting for the flow to drop.
- Ask for the TDS reading on every visit, so membrane decisions are made on numbers, not guesses.
- Approve only itemised quotes, and ask to see every old part before it is replaced.
- Compare pay-per-visit routine care (about ₹800 to ₹1,000 a year) with an AMC plan (₹1,999 to ₹3,999 a year) on your actual usage, not on a promised saving.
- Keep the service record: dates of filter and membrane changes make every future diagnosis faster and cheaper.
Year 1 vs Year 3: How Costs Change as the Purifier Ages
Yearly cost is not flat across a purifier's life. In the first year, routine care usually dominates: services and filter changes, roughly ₹800 to ₹1,000 for routine service and filters, with the membrane still in its early life. By the second or third year, the membrane reaches the end of its usual 1-to-2-year life, so a membrane year costs more than a routine year — the membrane is quoted after diagnosis, and its price depends on the purifier's model and capacity. Pumps and valves also become more likely to need attention as the machine ages, though many purifiers run years without pump work at all. The pattern to plan for is simple: budget the routine figure every year, and expect one heavier year when the membrane comes due. An AMC plan smooths this out into a single yearly figure — ₹1,999, ₹2,999 or ₹3,999 a year — which is why some families prefer it even when pay-per-visit routine care is cheaper in a light year.
The Hidden Cost of Skipping Service
Skipping a scheduled service never saves money for long. A choked pre-filter forces the pump to work harder, which shortens pump life and can turn a ₹199 filter change into a pump repair. A fouled membrane that could have lasted longer with on-time pre-filter changes ends up replaced early. A small leak left alone damages cabinets and wastes water daily. None of these costs appear as a single bill — they arrive as a bigger repair months later, and by then the link to the skipped service is easy to miss. The cheapest maintenance habit is also the simplest: service on schedule, change filters when readings say so, and keep the record of what was changed and when. That record is what lets every future visit start from knowledge instead of from zero.
