RO Water Purifier Service in Kolkata
RO Water Purifier Service in Kolkata follows the same fundamentals as anywhere in India, but two local factors change the schedule and the cost. Local supply measures 200-550 ppm TDS and the water is moderate, which determines how fast your pre-filters load and how long your membrane survives.
At Kolkata's comparatively moderate TDS, consumables last close to their rated life, so two service visits a year is generally sufficient. Do not stretch pre-filters beyond schedule though — they are what protect the far more expensive membrane.
Kolkata's water is comparatively moderate, so whole-house scaling is less of an issue here than in India's hard-water belt.

How to book properly in Kolkata
- Start from the brand's own website, not a sponsored search result. Many operators advertising "authorised service in Kolkata" have no relationship with the manufacturer, charge more, and fit non-genuine parts that can void your warranty.
- Insist on a ticket or complaint reference number, and note the promised response window.
- Have your model name, serial number, purchase date and a clear description of the symptom ready before you call — it shortens the visit and means the technician arrives with the right part.
- Ask for input and output TDS to be recorded on the slip at every visit. This is your evidence base and makes vague diagnoses much harder to sustain.
- If nobody attends within the promised window, escalate using the same ticket number — raising a fresh request resets your clock.
