ZeroB Non-Electric Water Purifiers: troubleshooting and FAQs
Troubleshooting tips and frequently asked questions for ZeroB Non-Electric Water Purifiers.
Troubleshooting tips
If the flow rate slows down, remove the candle filter and gently scrub its surface with a soft brush under running water to remove trapped sediments. Reinstall and check flow.
For improved taste and odour removal, replace the activated carbon filter every 6 months or after 6000 litres of usage, whichever is earlier.
If water leakage occurs at the candle housing, check the O-ring for wear or damage. Replace if necessary and tighten the housing by hand only—do not over-tighten.
To prevent bacterial growth, sanitise the purifier storage tank monthly using a mild bleach solution (1 teaspoon per litre of water), then rinse thoroughly with clean water before use.
If the purifier makes a whistling noise during filtration, it indicates air trapped in the system. Open the outlet tap and let water run for 2-3 minutes to release air.
