7 signs your RO water purifier needs servicing (and what to do)

A neglected RO purifier doesn't just stop giving water — it silently gives you worse water than your tap. Watch for these signs.

The 7 warning signs

• 1. Slow or trickling flow — clogged sediment/carbon filter.
• 2. Strange taste or smell — exhausted carbon or biofilm in tank.
• 3. TDS reading suddenly higher — membrane is failing.
• 4. Continuous water rejection — auto-shutoff fault or low pressure.
• 5. Noisy pump — air in line or motor wearing out.
• 6. Leakage near filters — O-ring or housing seal gone.
• 7. Service indicator blinking — annual maintenance overdue.
