Common Water Purifier Problems We See Every Day
Some issues start small but can quickly damage your purifier if ignored:
- Bad taste or smell in drinking water
- Low water flow or slow purification
- Water leakage from RO unit
- Purifier not turning on
- Frequent filter choking

These problems are especially common in areas with hard water, high TDS levels, or irregular maintenance. If you notice any of these warning signs, don't delay - early intervention prevents expensive damage and protects your family's health.

Why These Problems Occur (Real Causes)?
Most purifier issues are not manufacturing defects. They usually happen due to:
- Clogged filters caused by high sediment or hard water buildup
- Delayed filter replacement beyond recommended time period
- Faulty RO membrane or UV lamp performance degradation
- Poor inlet water pressure affecting filtration efficiency
- Improper installation or local wiring issues
- Using non-genuine spare parts that reduce durability
In Indian households, filters typically need replacement every 6 - 12 months, depending on water quality and usage. Skipping this maintenance leads to poor purification and internal damage to your system, requiring expensive PCB circuit repairs or complete RO membrane replacement.
Quick Troubleshooting Guide
| Symptom | Possible Cause | Solution |
| Salty or bitter taste | RO membrane failure or exhaustion | Professional replacement required |
| Continuous vibrating noise | Air in system or pump issue | Check inlet valve or call technician |
| Water tank not filling | Choked pre-filter or low pressure | Replace sediment filter (6-12 months) |
| Water leakage below unit | Damaged connector pipes | Call for pipe replacement service |
| TDS above 300 ppm | RO membrane end-of-life | Immediate membrane replacement needed |
Pro-Tip: If your TDS meter shows a reading above 300 ppm for purified water, your RO membrane has likely reached its end-of-life and requires professional replacement.

DIY Fixes That Often Make Things Worse
Many people try quick fixes after watching online videos. Some common mistakes include:
- Cleaning filters with tap water and reinstalling them without proper drying
- Ignoring leakage assuming it's "normal dripping" instead of a warning sign
- Running the purifier even when water tastes bad or discolored
- Resetting the purifier repeatedly without proper diagnosis of the issue
These actions can damage the RO membrane, pump, or PCB circuit, significantly increasing repair costs and reducing purifier lifespan. One wrong step costs ?5,000-15,000 in repairs.

You should contact Little Helpers immediately if:
- Water tastes salty, bitter, or smells odd despite filter changes

FAQ's
Q: How often should I change my water purifier filter?
Ans: In Indian households with hard water, filters need replacement every 6–12 months. High TDS areas may need more frequent changes.
Q: Why is my water still salty after filter replacement?
Ans: This indicates RO membrane failure, not just a filter issue. Call a technician for membrane replacement.
Q: Can I clean and reuse my filters?
Ans: No. Reusing filters can damage your purifier's PCB circuit and pump. Always use genuine replacement filters.
Q: What does TDS mean and why does it matter?
Ans: TDS (Total Dissolved Solids) measures water purity. Safe drinking water should have TDS below 50 ppm. If your purified water shows TDS above 300 ppm, your RO membrane has failed.
Q: How much does water purifier repair typically cost?
Ans: Filter replacement costs ?800-2,000. RO membrane replacement costs ?3,000-8,000. PCB repairs cost ?2,000-5,000. Call for transparent pricing.
