Most RO purifiers in Ahmedabad do not fail suddenly — they fade slowly. The water flow drops a little each month, the taste changes slightly, and one day the tank is empty when you need it most. A simple maintenance calendar prevents almost all of that. This guide gives Ahmedabad and Gandhinagar homes a practical year-round schedule: what to change, when to change it, and what it costs.
Why Ahmedabad Water Needs a Calendar
Ahmedabad's water varies a lot by area and source. Municipal water in many areas runs 200–500 ppm TDS, while borewell and tanker water in several pockets crosses 1,000 ppm. Higher TDS wears out pre-filters and membranes faster. That is why a fixed "once a year" approach fails here: your filter schedule should follow your water, and a TDS reading at every service visit tells you exactly where you stand.
Your Year-Round RO Maintenance Calendar
| Interval | What to do | Typical cost |
|---|---|---|
| Every 3–4 months | Change the sediment pre-filter; check carbon filter | ₹199 onwards |
| Every 6 months | General service: cleaning, TDS check, leak check, sanitisation | ₹299 |
| Every 12 months | Change carbon filter; full sanitisation; pump & SMPS check | As quoted upfront |
| Every 12–24 months | Change the RO membrane (depends on TDS & usage) | As quoted upfront |
| Every 24 months | Replace UV lamp (if fitted); inspect storage tank & tap | As quoted upfront |
Put simply: a home on normal municipal water usually needs two general services a year plus one pre-filter change between them. A home on borewell or high-TDS water needs pre-filter changes every 3 months and a closer watch on the membrane.
Seasonal Notes for Ahmedabad Homes
Summer: higher usage means faster filter loading. If flow drops in April–June, check the pre-filter first — it is the most common cause and the cheapest fix. Monsoon: municipal supply can turn muddy, which clogs sediment filters quickly; a mid-monsoon check saves you a breakdown later. Winter: lower usage is the right time for the annual deep service and sanitisation, when slots are easier to get.
What a 6-Month General Service Covers
Our ₹299 general service is a full check-up, not a wipe-down: exterior and storage-tank cleaning; inspection of all pre-filters plus the carbon filter; an RO membrane health check with a TDS meter reading taken before and after; sanitisation of the tap and dispenser nozzle; a booster-pump pressure and auto cut-off test; examination of every pipe joint for seepage; and a final taste-and-flow test done with you present. The visit takes 30–45 minutes. If any part needs replacement, the technician shows you the worn part, quotes the price upfront, and proceeds only after your approval.
Service, AMC or Pay-Per-Visit?
If your purifier needs attention twice or more a year, an AMC plan from ₹1,999/year usually works out cheaper than paying per visit — it covers scheduled services, free breakdown-visit labour, spare-part discounts and priority slots. For newer purifiers on normal municipal water, pay-per-visit service (₹150 visit, ₹299 service) is perfectly fine. The calendar above works either way: AMC simply makes the scheduled visits automatic.
If you are unsure which option fits your home, start with a single general service and a TDS reading. That visit tells you your water quality, your membrane's health, and how much life your filters have left — three facts that make the AMC-versus-pay-per-visit decision obvious. There is no pressure either way: the technician explains the numbers, and you choose the option that suits your usage and budget.
Signs Your Calendar Is Overdue
- Water flow from the tap has slowed noticeably, or the tank takes much longer to fill.
- The taste has changed, or the water smells different from usual.
- The purifier runs for a long time without cutting off, or makes a new noise.
- It has been more than 6 months since the last service, or more than 4 months since a pre-filter change on borewell water.
TDS Readings: The Number That Runs Your Calendar
If there is one number worth tracking, it is your water's TDS (total dissolved solids), measured in ppm. A healthy RO output in Ahmedabad usually reads well under 150 ppm, and a rising output reading is the earliest warning that the membrane is ageing — long before taste or flow changes. That is why every general service at Nyasa Enterprise includes a TDS reading before and after the work, shown to you on the spot. Keep a simple note of each reading (even a phone note works): if output TDS climbs steadily across two visits, plan the membrane change before it fails, rather than after. For homes on borewell water, where input TDS can exceed 1,000 ppm, readings matter even more, because the membrane works harder and its life shortens accordingly.
Your 12-Month Plan at a Glance
Here is the calendar as a simple yearly rhythm you can follow without thinking about it:
| Month | Action |
|---|---|
| January | General service + TDS check (start the year with a baseline reading) |
| March–April | Pre-filter change before summer usage rises |
| July | General service + mid-monsoon filter check |
| October | Pre-filter change; check carbon filter age |
| December | Annual deep service, sanitisation and membrane review |
Any one of the warning signs above means the calendar has slipped — book a general service and a TDS check. One ₹299 visit and a ₹199 pre-filter, done on time, routinely prevents a far more expensive membrane or pump failure later. Same-day service is available across Ahmedabad and Gandhinagar, Monday to Sunday, 8 AM to 8 PM — call +91 63560 23655 or WhatsApp us to get your purifier back on schedule.
