Mr Service Expert is a multi-brand appliance service team, and Zero B RO purifiers are among the models we service regularly in Sahjanwa, Uttar Pradesh. Book a visit for filter replacement, a repair or a full service.
Zero B RO Services We Offer in Sahjanwa
Here is what we can take care of during a visit:
- RO membrane replacement: the membrane is tested first, and replaced only when it has genuinely worn out.
- Leakage repair: replacing worn pipes, connectors and O-rings that cause leaks.
- Filter replacement: we replace the sediment and carbon cartridges that protect the RO membrane.
- SMPS and adapter repair: a faulty SMPS is a common reason a purifier suddenly goes dead.
- RO installation and uninstallation: wall mounting, inlet connection, drain setup and TDS testing for new or shifted purifiers.
- Solenoid and float valve: fixing valves that let water run to drain continuously or do not stop when the tank is full.
- Storage tank cleaning: tank sanitisation during service so stored water stays fresh.
- Annual maintenance plans: a planned schedule so you never miss a filter change.
- Booster pump repair: we check pump pressure and the power supply before replacing the pump.
About Zero B Water Purifiers
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.
Water Quality in Sahjanwa and Your RO
Hard water is common in and around Sahjanwa. Scale and salts shorten the life of filters and membranes, so we check the input TDS during every visit and adjust the service plan accordingly.
Common Zero B RO Problems We Fix
- Purifier not turning on: a failed SMPS, adapter or wiring fault.
- Purifier not switching off: a faulty float valve, solenoid valve or pressure switch.
- Bad taste or smell: exhausted carbon filters or a dirty storage tank.
- Water leaking from the unit: loose fittings, damaged pipes or a cracked filter housing.
- Low or no water output: clogged filters, a worn membrane or a weak pump.
- High output TDS: a membrane that has worn out or a TDS controller set too high.

Tips to Keep Your Zero B Purifier in Good Shape
A few simple habits between services go a long way:
- Use the purifier daily; water left standing for days in the tank is not ideal.
- Switch off the purifier if you are away for more than a few days, and flush it when you return.
- 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.
- Watch for slower filling or a change in taste; both are early warning signs.
- Clean the storage tank during every service.
