Whether it is a wall-mounted RO+UV model or a countertop unit, we service Zero B water purifiers across Sagardighi. Our focus is simple: safe, good-tasting water and a purifier that runs without trouble.
What We Do for Zero B RO Purifiers
Every visit starts with a proper check. Depending on the fault, the work can include:
- RO membrane replacement: the membrane is tested first, and replaced only when it has genuinely worn out.
- Booster pump repair: we check pump pressure and the power supply before replacing the pump.
- TDS adjustment: setting the output TDS to a healthy level for your water source.
- Filter replacement: we replace the sediment and carbon cartridges that protect the RO membrane.
- Storage tank cleaning: a hygienic clean of the storage tank to remove slime and deposits.
- Annual maintenance plans: scheduled service visits and filter changes through the year.
- Solenoid and float valve: a stuck valve can waste a lot of water, and it is a quick repair.

Water Purifier Care Tips
- Do not set output TDS too low; some minerals are good for taste and health.
- Use the purifier daily; water left standing for days in the tank is not ideal.
- Clean the storage tank during every service.
- Watch for slower filling or a change in taste; both are early warning signs.
- Keep the inlet valve and drain line free of kinks.
Water Quality in Sagardighi and Your RO
Water in many parts of Sagardighi, 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.

Is Your Zero B Purifier Showing These Signs?
Each of these has a clear cause that our technicians can find:
- Purifier not switching off: a faulty float valve, solenoid valve or pressure switch.
- Water leaking from the unit: water collecting under the purifier or on the wall.
- Noisy pump: a pump struggling against low inlet pressure or a failing motor.
- Low or no water output: clogged filters, a worn membrane or a weak pump.
- Purifier not turning on: a failed SMPS, adapter or wiring fault.
- Bad taste or smell: a change in taste is often the first sign that filters are due.
- High output TDS: a membrane that has worn out or a TDS controller set too high.
