About Zero B Water Purifiers
Zero B purifiers come from a brand with deep roots in water treatment technology. Our technicians service Zero B RO and UV models, replace cartridges and membranes, and repair electrical and flow-related faults.
Zero B RO Repair and Service Options
Our technicians handle the full range of Zero B water purifier work in Mangaldoi, including:
- Solenoid and float valve: a stuck valve can waste a lot of water, and it is a quick repair.
- 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 membrane replacement: a new membrane when output TDS rises or flow drops significantly.
- Leakage repair: replacing worn pipes, connectors and O-rings that cause leaks.
- Booster pump repair: we check pump pressure and the power supply before replacing the pump.
- Storage tank cleaning: tank sanitisation during service so stored water stays fresh.
- RO installation and uninstallation: neat installation with the inlet valve, drain line and electrical supply set up correctly.
- Annual maintenance plans: scheduled service visits and filter changes through the year.
Common Zero B RO Problems We Fix
- Purifier not switching off: a faulty float valve, solenoid valve or pressure switch.
- 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.
- UV light not working: a lamp that has reached end of life or a faulty UV circuit.
- Noisy pump: a pump struggling against low inlet pressure or a failing motor.
- High output TDS: a membrane that has worn out or a TDS controller set too high.
- Water leaking from the unit: loose fittings, damaged pipes or a cracked filter housing.

Water Purifier Care Tips
- Switch off the purifier if you are away for more than a few days, and flush it when you return.
- Clean the storage tank during every service.
- Get the RO membrane checked once a year; it typically lasts 1 to 2 years depending on water quality.
- Keep the inlet valve and drain line free of kinks.
- Watch for slower filling or a change in taste; both are early warning signs.

Water Quality in Mangaldoi and Your RO
During the rains, water supply in Mangaldoi can turn muddy. That quickly clogs sediment filters, so we recommend a check-up after heavy monsoon months.
