About Zero B Water Purifiers
Zero B purifiers come from a brand with deep roots in water treatment technology. Our technicians service Zero B RO and UV models, replace cartridges and membranes, and repair electrical and flow-related faults.
Zero B RO Repair and Service Options
- RO membrane replacement: the membrane is tested first, and replaced only when it has genuinely worn out.
- UV lamp and UF membrane: UV and UF stages checked and restored so disinfection works properly.
- Booster pump repair: repair or replacement of pumps that are noisy, weak or not starting.
- Filter replacement: sediment, pre-carbon and post-carbon filters changed as per water quality and usage.
- Leakage repair: we trace the leak to its source and fix it properly.
- TDS adjustment: we test input and output water and adjust the TDS controller where your model has one.
- Annual maintenance plans: scheduled service visits and filter changes through the year.
- RO installation and uninstallation: neat installation with the inlet valve, drain line and electrical supply set up correctly.
- Solenoid and float valve: fixing valves that let water run to drain continuously or do not stop when the tank is full.
Is Your Zero B Purifier Showing These Signs?
Call us if you notice any of these:
- Low or no water output: the tank takes much longer to fill than it used to.
- UV light not working: the UV indicator is off or blinking.
- Purifier not turning on: a failed SMPS, adapter or wiring fault.
- Noisy pump: loud humming or vibration during filling.
- High output TDS: a membrane that has worn out or a TDS controller set too high.
- Purifier not switching off: the pump keeps running and water flows to drain non-stop.
- Bad taste or smell: exhausted carbon filters or a dirty storage tank.
Tips to Keep Your Zero B Purifier in Good Shape
You can avoid many breakdowns with a little care:
- Clean the storage tank during every service.
- Get the RO membrane checked once a year; it typically lasts 1 to 2 years depending on water quality.
- Do not set output TDS too low; some minerals are good for taste and health.
- Keep the inlet valve and drain line free of kinks.
- Replace the sediment filter every 6 to 12 months, or sooner if your water is muddy.
Why Local Water Matters
In Koraon, Uttar Pradesh, borewell and tanker water can carry a high level of dissolved salts. An RO purifier handles this well when its pre-filters and membrane are in good condition, which is why regular servicing matters here.
