A water purifier works quietly in the background until something goes wrong. When your Zero B RO stops giving water, runs non-stop or shows a TDS problem, our team in Kollam can diagnose and fix it, usually in a single visit. Book a slot on 9311587715, including weekends.
Servicing Every Zero B Purifier Model
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.
What We Do for Zero B RO Purifiers
Here is what we can take care of during a visit:
- Booster pump repair: repair or replacement of pumps that are noisy, weak or not starting.
- Solenoid and float valve: a stuck valve can waste a lot of water, and it is a quick repair.
- SMPS and adapter repair: a faulty SMPS is a common reason a purifier suddenly goes dead.
- TDS adjustment: we test input and output water and adjust the TDS controller where your model has one.
- RO membrane replacement: a new membrane when output TDS rises or flow drops significantly.
- Storage tank cleaning: a hygienic clean of the storage tank to remove slime and deposits.
- Annual maintenance plans: a planned schedule so you never miss a filter change.
- Filter replacement: we replace the sediment and carbon cartridges that protect the RO membrane.
- RO installation and uninstallation: neat installation with the inlet valve, drain line and electrical supply set up correctly.
Common Zero B RO Problems We Fix
Call us if you notice any of these:
- 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.
- High output TDS: a membrane that has worn out or a TDS controller set too high.
- UV light not working: a lamp that has reached end of life or a faulty UV circuit.
- Purifier not switching off: the pump keeps running and water flows to drain non-stop.
- Water leaking from the unit: loose fittings, damaged pipes or a cracked filter housing.
Tips to Keep Your Zero B Purifier in Good Shape
- Keep the inlet valve and drain line free of kinks.
- Use the purifier daily; water left standing for days in the tank is not ideal.
- 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.

Why Local Water Matters
During the rains, water supply in Kollam can turn muddy. That quickly clogs sediment filters, so we recommend a check-up after heavy monsoon months.
