If your RO water purifier in Kolkata is giving bad taste, slow water flow, odd smell, or it is not producing enough purified water, you usually do not need guesswork. Most issues come from clogged pre-filters, exhausted RO membrane, carbon filter wear, low inlet pressure, or electrical problems in the booster pump/SMPS. A technician from Water Purifier Care India (WPCI) typically starts by reading your symptoms first, then checks the right stage of the system.
Bad taste or salty taste: often points to RO membrane exhaustion or a bypass/leak in the reject line
Bad smell (stale/chemical): usually indicates carbon filter saturation or improper post-carbon performance
Slow filling / low output: commonly clogged sediment pre-filter, low inlet pressure (municipal or borewell), or a weak booster pump
Machine keeps running or does not stop properly: usually float/pressure switch or solenoid valve (SV) control issue
Water leakage from the housing or fittings: typically O-rings, loose connections, cracked cap, or membrane housing seepage
No water / very low production: could be low inlet pressure, blocked filters, UV/UF cartridge faults (if present), or electrical faults in pump/SMPS
Check supply pressure at the inlet and whether water flow is steady (borewell and municipal both vary in Kolkata)
Inspect pre-filters and wash/replace the sediment filter if it is heavily dirty from monsoon turbidity
Test and inspect post-carbon and (if installed) UV/UF stages for fouling or lamp/cartridge ageing
Measure RO performance by checking reject ratio, TDS readings before/after RO (with a TDS meter)
Inspect membrane housing for leaks and check for airlock/flow restrictions
Open electrical controls: booster pump condition, SMPS, wiring, solenoid valve (SV), and float/pressure switch response
Kolkata water often brings higher suspended particles during monsoon, which clogs the sediment pre-filter faster. Hard water and high TDS also push scaling on the RO membrane, reducing rejection and causing salty taste. Carbon filters get exhausted when they can no longer remove odour and dissolved impurities, so the smell returns even if RO is working partially.
Stage (typical RO system) | What typically fails | Typical maintenance interval (rough guide) |
|---|---|---|
Sediment pre-filter | Clogging from turbidity | 3-6 months |
Pre-carbon / post-carbon (where used) | Odour/taste return when carbon saturates | 6-12 months |
RO membrane | Low rejection, salty taste, high TDS in purified water | 2-3 years (varies with input TDS and usage) |
UV lamp (if installed) | Lamp ageing leads to sanitation performance drop | About 1 year of running time (depends on usage) |
Cost depends on which stage is failing (filters vs RO membrane vs electrical parts), whether parts can be cleaned or must be replaced, and how severe the scaling or clogging is. Time depends on diagnostics plus whether the technician needs to swap components like the membrane, carbon filters, pump, SMPS, or an SV. In most cases, a RO purifier is worth repairing if the leakage is limited and the membrane is not completely exhausted; if membrane performance is consistently poor and scaling is heavy, replacement is usually the sensible fix.
Check if inlet water supply is coming regularly (no supply means RO cannot produce)
Look for obvious leaks around the storage tank, membrane housing, and tap connections
Note the TDS readings if your unit shows both inlet and outlet (if you have a TDS meter)
Observe whether the RO starts and then stops normally, or keeps running continuously
If you recently had a power cut or voltage fluctuation, check if the booster pump is humming or completely silent
If the issue is salty taste, high TDS, continuous running, or leakage, do not keep using the unit for long. Call WaterPurifierCareIndia (WPCI) for a symptom-based diagnosis so the technician checks the correct stage first, instead of changing parts blindly.

Also, ask them about the service centre experience in Kolkata. If possible, visit the nearby shop which sells RO water purifiers and get to know the amount of TDS in the supplied water in your Kolkata locality.
If the above ways don’t work for you, then the last resort is the internet. For those who are more of an internet guy and have a smartphone with data or Wi-Fi in Kolkata, then get on to it.
