Zero B RO Faults We Repair Regularly
- Noisy pump: loud humming or vibration during filling.
- UV light not working: a lamp that has reached end of life or a faulty UV circuit.
- Low or no water output: clogged filters, a worn membrane or a weak pump.
- Bad taste or smell: exhausted carbon filters or a dirty storage tank.
- Water leaking from the unit: loose fittings, damaged pipes or a cracked filter housing.
- Purifier not turning on: no lights and no sound when the unit is switched on.
- High output TDS: the purified water tests higher than it should.
Tips to Keep Your Zero B Purifier in Good Shape
- Replace the sediment filter every 6 to 12 months, or sooner if your water is muddy.
- Watch for slower filling or a change in taste; both are early warning signs.
- Get the RO membrane checked once a year; it typically lasts 1 to 2 years depending on water quality.
- Use the purifier daily; water left standing for days in the tank is not ideal.
