Frequently asked questions

Everything about Zero B RO Water Purifier service in Kolkata

Is Mr Service Expert the official Zero B service centre?

No. Mr Service Expert is an independent multi-brand service provider. We service Zero B purifiers but are not affiliated with or authorised by Zero B.

How much does Zero B RO service cost in Kolkata?

The cost depends on whether you need a general service, filter replacement or a repair. The technician shares the price before starting. Call 9311587715 for an estimate.

Do you use genuine filters for Zero B purifiers?

We use genuine or quality-matched filters depending on availability, and we explain the option and price before fitting anything.

Why does my purifier keep running and not stop?

This usually points to a faulty float valve, solenoid valve or pressure switch. It wastes water and should be fixed quickly.

How often should I service my Zero B RO purifier in Kolkata?

Most homes need a service every 3 to 6 months, with filters replaced every 6 to 12 months depending on water quality and usage. Hard or muddy water may need more frequent changes.

What are the signs that my RO water purifier needs immediate service in Kolkata?

Over time, your RO system may show signs such as an unusual taste or odor in the water, slow filtration, or leakage. If you are in Kolkata and are noticing any of these symptoms, it's time to book a professional RO service to ensure clean and safe drinking water.

Why and when should I get RO service in Kolkata?

In Kolkata, regular RO service is important due to high TDS levels, water hardness and seasonal contamination - especially during monsoons and summers. Getting your RO purifier serviced every 3 to 6 months helps maintain water quality, improve filtration performance, prevent bad taste or odour, and extend the life of the purifier. Timely maintenance also reduces the risk of health problems caused by unfiltered or impure water.

What is the cost of RO service in Kolkata?

If any filters or parts need replacement, charges are communicated transparently before proceeding.

Zero B RO Services We Offer in Kolkata

Our Experience with Zero B RO Units

Zero B RO Faults We Repair Regularly

  • Low or no water output: the tank takes much longer to fill than it used to.
  • Purifier not turning on: no lights and no sound when the unit is switched on.
  • UV light not working: the UV indicator is off or blinking.
  • Noisy pump: a pump struggling against low inlet pressure or a failing motor.
  • High output TDS: a membrane that has worn out or a TDS controller set too high.
  • Purifier not switching off: a faulty float valve, solenoid valve or pressure switch.

  • Quality filters and membranes – genuine or quality-matched parts, with the option explained to you.

Tips to Keep Your Zero B Purifier in Good Shape

Our technicians suggest these easy steps:

  • Use the purifier daily; water left standing for days in the tank is not ideal.
  • Watch for slower filling or a change in taste; both are early warning signs.
  • Clean the storage tank during every service.
  • Switch off the purifier if you are away for more than a few days, and flush it when you return.

Why Local Water Matters

During the rains, water supply in Kolkata can turn muddy. That quickly clogs sediment filters, so we recommend a check-up after heavy monsoon months.

Our Simple Service Process

  • Call 9311587715 and tell us your purifier model and the problem.
  • A technician is assigned and a time is fixed for you.
  • Input and output TDS are checked and the charges are shared before work.
  • Parts are changed with clean hands and the area is left dry and tidy.
  • We test the purified water in front of you before leaving.
