About Zero B Water Purifiers
Zero B purifiers come from a brand with deep roots in water treatment technology. Our technicians service Zero B RO and UV models, replace cartridges and membranes, and repair electrical and flow-related faults.
Zero B RO Repair and Service Options
- RO membrane replacement: a new membrane when output TDS rises or flow drops significantly.
- Annual maintenance plans: scheduled service visits and filter changes through the year.
- Solenoid and float valve: fixing valves that let water run to drain continuously or do not stop when the tank is full.
- UV lamp and UF membrane: replacement of UV lamps that have stopped glowing and UF membranes that have clogged.
- Leakage repair: we trace the leak to its source and fix it properly.
- Booster pump repair: repair or replacement of pumps that are noisy, weak or not starting.
- Storage tank cleaning: tank sanitisation during service so stored water stays fresh.
Water Quality in Onda and Your RO
Water in many parts of Onda, West Bengal is relatively low in dissolved salts but can carry silt or iron. Your purifier's pre-filters work hard in these conditions, and we replace them on a schedule suited to your supply.
Water Purifier Care Tips
- Get the RO membrane checked once a year; it typically lasts 1 to 2 years depending on water quality.
- Watch for slower filling or a change in taste; both are early warning signs.
- Use the purifier daily; water left standing for days in the tank is not ideal.
- Replace the sediment filter every 6 to 12 months, or sooner if your water is muddy.

Zero B RO Faults We Repair Regularly
Each of these has a clear cause that our technicians can find:
- High output TDS: the purified water tests higher than it should.
- Purifier not switching off: the pump keeps running and water flows to drain non-stop.
- Noisy pump: loud humming or vibration during filling.
- Purifier not turning on: a failed SMPS, adapter or wiring fault.
- Bad taste or smell: exhausted carbon filters or a dirty storage tank.
- UV light not working: the UV indicator is off or blinking.
