Zero B RO Services We Offer in Barauli
- Leakage repair: we trace the leak to its source and fix it properly.
- SMPS and adapter repair: a faulty SMPS is a common reason a purifier suddenly goes dead.
- Storage tank cleaning: a hygienic clean of the storage tank to remove slime and deposits.
- Filter replacement: sediment, pre-carbon and post-carbon filters changed as per water quality and usage.
- Booster pump repair: repair or replacement of pumps that are noisy, weak or not starting.
- TDS adjustment: we test input and output water and adjust the TDS controller where your model has one.
- RO membrane replacement: the membrane is tested first, and replaced only when it has genuinely worn out.
- Solenoid and float valve: a stuck valve can waste a lot of water, and it is a quick repair.
- RO installation and uninstallation: wall mounting, inlet connection, drain setup and TDS testing for new or shifted purifiers.
Our Experience with Zero B RO Units
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.

Zero B RO Faults We Repair Regularly
Call us if you notice any of these:
- Water leaking from the unit: loose fittings, damaged pipes or a cracked filter housing.
- Bad taste or smell: a change in taste is often the first sign that filters are due.
- High output TDS: a membrane that has worn out or a TDS controller set too high.
- Purifier not turning on: a failed SMPS, adapter or wiring fault.
- Noisy pump: loud humming or vibration during filling.
- Low or no water output: clogged filters, a worn membrane or a weak pump.
- Purifier not switching off: a faulty float valve, solenoid valve or pressure switch.
Why Local Water Matters
Water quality varies from one neighbourhood to the next, even within Barauli. 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
You can avoid many breakdowns with a little care:
- 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.
- Replace the sediment filter every 6 to 12 months, or sooner if your water is muddy.
- Clean the storage tank during every service.
