Our Experience with Zero B RO Units
Zero B is the water purifier brand of Ion Exchange (India), a company with a long background in water treatment. The Zero B range includes RO, UV and non-electric purifiers, and we service each type with the right approach.
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.

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.

- A technician is assigned and a time is fixed for you.
