Servicing Every Zero B Purifier Model
Many Zero B RO purifiers use a combination of sediment, carbon and RO stages, often with UV or mineral add-ons. Keeping each stage in good condition is what protects both water quality and the life of the membrane.
Complete Zero B Water Purifier Care in Dankuni
Here is what we can take care of during a visit:
- TDS adjustment: we test input and output water and adjust the TDS controller where your model has one.
- RO installation and uninstallation: neat installation with the inlet valve, drain line and electrical supply set up correctly.
- Annual maintenance plans: scheduled service visits and filter changes through the year.
- Leakage repair: we trace the leak to its source and fix it properly.
- Filter replacement: we replace the sediment and carbon cartridges that protect the RO membrane.
- RO membrane replacement: a new membrane when output TDS rises or flow drops significantly.
- Booster pump repair: we check pump pressure and the power supply before replacing the pump.
- SMPS and adapter repair: a faulty SMPS is a common reason a purifier suddenly goes dead.
Is Your Zero B Purifier Showing These Signs?
Each of these has a clear cause that our technicians can find:
- Water leaking from the unit: water collecting under the purifier or on the wall.
- Purifier not turning on: no lights and no sound when the unit is switched on.
- Purifier not switching off: a faulty float valve, solenoid valve or pressure switch.
- Low or no water output: clogged filters, a worn membrane or a weak pump.
- Noisy pump: a pump struggling against low inlet pressure or a failing motor.
- UV light not working: a lamp that has reached end of life or a faulty UV circuit.
- High output TDS: the purified water tests higher than it should.
Water Purifier Care Tips
A few simple habits between services go a long way:
- Clean the storage tank during every service.
- Do not set output TDS too low; some minerals are good for taste and health.
- Switch off the purifier if you are away for more than a few days, and flush it when you return.
- Get the RO membrane checked once a year; it typically lasts 1 to 2 years depending on water quality.
Water Quality in Dankuni and Your RO
Water quality varies from one neighbourhood to the next, even within Dankuni. Municipal supply, borewell and tanker water each affect a purifier differently. We test your input water and recommend filter changes based on it, not on guesswork.
