RO service cost in Delhi NCR: what you should be paying
By Kanak Enterprises, who rent and service RO purifiers across Delhi NCR.
The short answer
A standard RO service visit in Delhi NCR costs roughly ₹350–₹600 for labour, with parts quoted separately: sediment and carbon filters around ₹150–₹400 each, an RO membrane ₹1,500–₹2,500, and a booster pump ₹1,200–₹2,000. A basic annual maintenance contract runs ₹3,000–₹4,500 a year. On a rental plan all of it is included in the monthly rent.
Key takeaways
- A service visit is ₹350–₹600 in labour; parts are quoted on top and should be approved before fitting.
- Pre-filters need changing every 3 months, the membrane roughly annually on high-TDS NCR water.
- Basic AMC is ₹3,000–₹4,500 a year; comprehensive, which covers membrane and pump, is ₹5,000–₹6,500.
- Skipping pre-filter changes is the main cause of premature membrane and pump failure.
- Insist on a quote before work starts, and on the old part being shown to you.
RO servicing in Delhi NCR is an unregulated market with no published price list, which is exactly the condition in which people get overcharged. The figures below are the going rates. They are not our quotes — they are what you should expect from any competent technician, so you can tell a fair bill from an invented one.
What each job should cost
| Job or part | Typical price | How often it is needed |
|---|---|---|
| Standard service visit (labour) | ₹350–₹600 | Every 3 months |
| Sediment filter | ₹150–₹300 | Every 3–6 months |
| Carbon filter | ₹200–₹400 | Every 6 months |
| Post-carbon / polisher | ₹200–₹400 | Annually |
| RO membrane | ₹1,500–₹2,500 | Annually on high-TDS water |
| Booster pump | ₹1,200–₹2,000 | Year 3–5, if at all |
| Solenoid (SV) valve | ₹400–₹600 | Occasional |
| Float valve | ₹150–₹300 | Occasional |
| SMPS / adaptor | ₹500–₹900 | Occasional |
| Basic AMC | ₹3,000–₹4,500 / year | Annual contract |
| Comprehensive AMC | ₹5,000–₹6,500 / year | Annual contract |
How often servicing is genuinely needed
Over-servicing is the most common way a bill gets inflated, so it is worth knowing the real schedule.
- Pre-filters (sediment and carbon): every three months. This is the visit that actually matters, and the one people skip.
- RO membrane: roughly annually on Delhi NCR borewell water; two to three years on treated municipal supply. Judge it by output TDS, not by the calendar.
- Post-carbon polisher: annually.
- UV lamp, if fitted: annually — the lamp keeps glowing long after its output has decayed below useful intensity.
- Full teardown and sanitisation: annually.
The pre-filter schedule is not optional maintenance. A choked sediment filter forces the booster pump to work against resistance and lets particles reach the membrane, so skipping ₹300 filters is how people arrive at a ₹2,200 membrane and a ₹1,600 pump inside two years.
Three quotes that should prompt a second opinion
"The membrane needs changing" — at every visit
A membrane lasts about a year on hard NCR water and longer on municipal supply. If it is being replaced every six months, either it is not actually being replaced, or the pre-filters are being neglected so badly that they are destroying it. Ask for the output TDS reading before and after — a healthy membrane shows a large drop.
A single bundled figure with no breakdown
"₹4,000 for full service" is not a quote, it is a number. Every legitimate job separates labour from parts and names each part. Ask for the split before agreeing to anything.
Urgency about a part you cannot see
Ask to be shown the old component. A technician replacing a genuinely failed pump or valve will hand it to you without hesitation. Reluctance is informative.
Is an AMC worth it?
Add up the routine work at list price: four service visits, two sediment filters, one carbon, one post-carbon. That lands close to ₹3,000 — roughly the price of a basic AMC, which also throws in unlimited breakdown visits. So a basic AMC is broadly fair value rather than a bargain; what you are really buying is the removal of per-visit haggling.
A comprehensive AMC at ₹5,000–₹6,500 is the better deal on high-TDS borewell water, where membranes are consumed fast enough that one covered replacement pays for much of the difference. On treated municipal supply it usually is not worth the premium.
The third option is not to own the machine at all. On a rental plan every item in this article is included in the rent, which is why the maintenance question stops being a question.
Frequently asked questions
How much does RO service cost in Delhi NCR?
A standard service visit costs about ₹350–₹600 in labour, with parts quoted separately — sediment and carbon filters at ₹150–₹400 each, an RO membrane at ₹1,500–₹2,500 and a booster pump at ₹1,200–₹2,000. A basic annual maintenance contract covering the routine work runs ₹3,000–₹4,500 a year.
How often should an RO be serviced?
Pre-filters every three months, the RO membrane roughly annually on Delhi NCR's high-TDS borewell water, and a UV lamp annually if one is fitted. Skipping the quarterly pre-filter change is the single biggest cause of premature membrane and pump failure.
How much does an RO membrane cost?
₹1,500–₹2,500 for a domestic membrane in Delhi NCR, depending on capacity and brand. On high-TDS borewell water expect to replace it about once a year; on treated municipal supply it can last two to three years.
Is an RO AMC worth it?
A basic AMC at ₹3,000–₹4,500 costs roughly what the routine work costs at list price, so it buys convenience more than savings. A comprehensive AMC is genuinely worth it on high-TDS borewell water, where a covered membrane replacement recovers much of the premium. On a rental plan no AMC is needed, since everything is already included.

Everyone compares the sticker price. The number that actually decides it is the break-even year — and for a typical Delhi NCR household it lands well past the life of the machine.
