Whether it is a wall-mounted RO+UV model or a countertop unit, we service Zero B water purifiers across Sunauli. Our focus is simple: safe, good-tasting water and a purifier that runs without trouble.
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 Sunauli
Here is what we can take care of during a visit:
- RO membrane replacement: a new membrane when output TDS rises or flow drops significantly.
- Annual maintenance plans: a planned schedule so you never miss a filter change.
- SMPS and adapter repair: fixing power supply units that stop the purifier from switching on.
- 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.
- TDS adjustment: setting the output TDS to a healthy level for your water source.
- RO installation and uninstallation: wall mounting, inlet connection, drain setup and TDS testing for new or shifted purifiers.
Our Simple Service Process
Booking takes a couple of minutes:
- Share your address and issue with our team on 9311587715.
- We confirm a convenient visit slot in Sunauli.
- The technician tests the water and the unit, then explains the fault and cost.
- 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.
Zero B RO Faults We Repair Regularly
Each of these has a clear cause that our technicians can find:
- Purifier not turning on: no lights and no sound when the unit is switched on.
- Low or no water output: the tank takes much longer to fill than it used to.
- Bad taste or smell: a change in taste is often the first sign that filters are due.
- Water leaking from the unit: water collecting under the purifier or on the wall.
- High output TDS: a membrane that has worn out or a TDS controller set too high.
- UV light not working: the UV indicator is off or blinking.
Water Quality in Sunauli and Your RO
Water quality varies from one neighbourhood to the next, even within Sunauli. 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.

How to Get the Best from Your Zero B RO
- Watch for slower filling or a change in taste; both are early warning signs.
- 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.
- 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.
