What We Do for Zero B RO Purifiers
- Filter replacement: sediment, pre-carbon and post-carbon filters changed as per water quality and usage.
- Booster pump repair: we check pump pressure and the power supply before replacing the pump.
- RO membrane replacement: the membrane is tested first, and replaced only when it has genuinely worn out.
- RO installation and uninstallation: neat installation with the inlet valve, drain line and electrical supply set up correctly.
- SMPS and adapter repair: a faulty SMPS is a common reason a purifier suddenly goes dead.
- TDS adjustment: we test input and output water and adjust the TDS controller where your model has one.
- Leakage repair: replacing worn pipes, connectors and O-rings that cause leaks.
- UV lamp and UF membrane: UV and UF stages checked and restored so disinfection works properly.
About Zero B Water Purifiers
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.
Common Zero B RO Problems We Fix
- High output TDS: a membrane that has worn out or a TDS controller set too high.
- Noisy pump: loud humming or vibration during filling.
- Purifier not turning on: no lights and no sound when the unit is switched on.
- Water leaking from the unit: water collecting under the purifier or on the wall.
- Purifier not switching off: the pump keeps running and water flows to drain non-stop.

Tips to Keep Your Zero B Purifier in Good Shape
You can avoid many breakdowns with a little care:
- Use the purifier daily; water left standing for days in the tank is not ideal.
- Do not set output TDS too low; some minerals are good for taste and health.
- Get the RO membrane checked once a year; it typically lasts 1 to 2 years depending on water quality.
- Keep the inlet valve and drain line free of kinks.
