Don't Ignore These Warning Signs
Your RO water purifier works hard 24/7 to keep you healthy. Like any machine, it occasionally runs into issues. Here are 5 common problems and what they mean:
- Water Leakage: Usually caused by loose pipe fittings or a cracked filter housing. Needs immediate tightening or replacement.
- Vibrating Noise: A loud humming noise often means the booster pump is failing or there is trapped air in the system.
- Bad Tasting Water: If the water tastes bitter or smells bad, the post-carbon filter has likely expired.
- Slow Water Flow: This indicates that the pre-filter or the main RO membrane is heavily choked with mud and salts.
- Continuous Waste Water Flow: If water keeps draining even when the tank is full, the Auto-Shut-Off (ASV) valve is malfunctioning.
