What We Do for Zero B RO Purifiers
Every visit starts with a proper check. Depending on the fault, the work can include:
- 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.
- Filter replacement: we replace the sediment and carbon cartridges that protect the RO membrane.
- UV lamp and UF membrane: replacement of UV lamps that have stopped glowing and UF membranes that have clogged.
- SMPS and adapter repair: fixing power supply units that stop the purifier from switching on.
- RO installation and uninstallation: neat installation with the inlet valve, drain line and electrical supply set up correctly.
- RO membrane replacement: the membrane is tested first, and replaced only when it has genuinely worn out.
- Storage tank cleaning: a hygienic clean of the storage tank to remove slime and deposits.
- Leakage repair: replacing worn pipes, connectors and O-rings that cause leaks.
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 East Delhi and Your RO
In East Delhi, 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.
Common Zero B RO Problems We Fix
- Low or no water output: clogged filters, a worn membrane or a weak pump.
- UV light not working: a lamp that has reached end of life or a faulty UV circuit.
- High output TDS: the purified water tests higher than it should.
- Water leaking from the unit: water collecting under the purifier or on the wall.
- Purifier not turning on: no lights and no sound when the unit is switched on.

How to Get the Best from Your Zero B RO
Our technicians suggest these easy steps:
- Do not set output TDS too low; some minerals are good for taste and health.
- Watch for slower filling or a change in taste; both are early warning signs.
- 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.
- 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.
