Complete Zero B Water Purifier Care in Dumka
Here is what we can take care of during a visit:
- RO installation and uninstallation: wall mounting, inlet connection, drain setup and TDS testing for new or shifted purifiers.
- SMPS and adapter repair: fixing power supply units that stop the purifier from switching on.
- TDS adjustment: setting the output TDS to a healthy level for your water source.
- Storage tank cleaning: tank sanitisation during service so stored water stays fresh.
- Solenoid and float valve: fixing valves that let water run to drain continuously or do not stop when the tank is full.
- UV lamp and UF membrane: replacement of UV lamps that have stopped glowing and UF membranes that have clogged.
- Booster pump repair: we check pump pressure and the power supply before replacing the pump.
- RO membrane replacement: a new membrane when output TDS rises or flow drops significantly.
- Filter replacement: we replace the sediment and carbon cartridges that protect the RO membrane.
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 Purifier Care Tips
Our technicians suggest these easy steps:
- 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.
- Replace the sediment filter every 6 to 12 months, or sooner if your water is muddy.
