Category: Water Treatment

Clean and safe drinking water is a priority for every Nepali household. With increasing concerns over water quality in Kathmandu Valley, Lalitpur, Bhaktapur, Pokhara and major cities, RO Water Purifiers have become essential for homes, offices, schools, restaurants, and hospitals.
However, like any appliance, RO systems also develop issues over time — especially due to Nepal’s varying water quality, sediment, iron, and TDS levels.

This article explains the most common RO Filter problems in Nepal and practical solutions, helping you understand when to troubleshoot and when to call professional service support.

💧 Why RO Water Purifiers Are Increasing in Nepal

Nepal’s water sources vary from:

• Tap water supply
• Borewell / groundwater
• Tanker water
• Filtered municipal supply

While many households believe boiling water solves problems, it doesn’t remove:

• dissolved salts
• heavy metals
• chemical contaminants
• high TDS
• hardness

That’s where RO (Reverse Osmosis) systems help. They:

• reduce TDS
• improve taste
• remove harmful impurities
• make water safe for long-term health

However, due to high sediment, iron particles, and frequent power fluctuations in Nepal, RO filters may face problems if not serviced regularly.

⚠️ Common RO Filter Problems in Nepal & Their Solutions

1️⃣ RO Purifier Not Dispensing Water / No Water Flow

✔ Possible Causes

• Clogged pre-filter or sediment filter
• Blocked RO membrane
• Choked pipelines or valves
• Low incoming water pressure
• Tank is full or pressure switch failure

✔ Solution

• Replace pre-filter if clogged
• Check water pressure
• Replace RO membrane if needed
• Reset or service water pressure valve

👉 If unsure, call a professional RO technician.

2️⃣ RO Water Flow is Very Slow / Tank Filling Very Late

A very common complaint in Kathmandu Valley and urban homes.

✔ Causes

• Sediment choke due to dusty tank / pipeline water
• RO membrane exhausted
• Low water pressure
• Faulty booster pump

✔ Solution

• Service filters every 6–12 months
• Replace membrane every 2–3 years (depending on usage & water quality)
• Install booster pump if needed

3️⃣ RO Water Has Bad Taste or Smell

If your water tastes salty, metallic, bitter or smells unusual…

✔ Causes

• Carbon filter expired
• Bacteria buildup due to lack of service
• TDS imbalance
• Wrong/duplicate filters installed

✔ Solution

• Replace post-carbon filter
• Sanitize storage tank
• Monitor TDS regularly
• Always use genuine replacement filters

4️⃣ Water Leakage From RO Filter

One of the most reported problems in Nepal.

✔ Causes

• Loose pipe connections
• Cracked filter housing
• Damaged O-rings
• Poor installation

✔ Solution

• Tighten pipe and fitting
• Replace O-rings
• Repair or replace cracked housing
• Always use professional installation services

5️⃣ RO Purifier Making Noise While Running

This mostly happens in older or poorly maintained systems.

✔ Causes

• Booster pump problem
• Air trapped in the system
• Vibrating pipes
• Loose fittings

✔ Solution

• Check pump
• Release trapped air
• Secure pipes properly

6️⃣ RO Machine Not Turning On / No Power

This is rare but happens due to Nepal’s power fluctuation.

✔ Causes

• Power adapter failure
• Faulty wiring
• Switch failure

✔ Solution

• Check adapter
• Replace wiring
• Get professional inspection

7️⃣ RO Purifier Running Continuously / Continuous Water Drain

This wastes water and increases operational cost.

✔ Causes

• Malfunctioning auto-cut
• SV valve issue
• Faulty float valve

✔ Solution

• Repair electrical components
• Replace faulty valves

8️⃣ High TDS in RO Output

If your RO is installed but water still seems salty…

✔ Causes

• RO membrane failure
• Wrong setup
• Expired filters

✔ Solution

• Test TDS
• Replace membrane
• Get system checked by an expert

💡 Why RO Problems Are Common in Nepal

Nepal’s water contains:

• high sediment
• iron content in groundwater
• contamination in tanker water
• aging pipes causing rust

Because of this, filters clog faster, making regular service essential.

🧰 How to Prevent RO Filter Problems – Maintenance Tips for Nepal

✔ Change pre-filter every 6–12 months
✔ Service your RO system at least once a year
✔ Replace RO membrane every 2–3 years
✔ Avoid duplicate / cheap filters
✔ Flush system periodically
✔ Get installation done by experts

🧾 When Should You Replace vs Repair Your RO Filter?

Replace when:

• Repair cost is too high
• Water quality remains bad even after servicing
• Unit is 6–8+ years old

Repair when:

• Minor leakage
• Slow flow issues
• Power-related fixes required

Serving: Kathmandu • Bhaktapur • Lalitpur • Surrounding Regions

In Nepal, clean and safe drinking water is more than a luxury—it’s essential for good health. At Multipower Solution, we specialize in water treatment and RO filter systems tailored for the needs of households, offices, and businesses in Kathmandu, Bhaktapur, Lalitpur, and across Nepal. Whether your water source is well, municipal line (KUKL), or borehole, we provide systems that reliably remove contaminants and make your water safe, great-tasting, and suitable for daily use.

Why Water Treatment & RO Filters are Crucial in Kathmandu, Bhaktapur & Lalitpur

• Contaminants in Local Water Sources: Pipes may suffer damage, seepage, and contamination. Rivers, ground water, boreholes often contain suspended particles, heavy metals, microbes, and sometimes high TDS (total dissolved solids).
• Health Risks: Without proper purification, waterborne diseases (diarrhoea, skin problems, typhoid etc.) are common. Clean, safe water through proper filtration significantly reduces these risks.
• Monsoon & Turbidity Issues: During rains, water becomes turbid; municipal supply may carry silt. Effective pre-filtration, sediment filters, UV/UF & RO filtration help to ensure clarity and safety.
• Taste & Odour: Chlorine smell, chemical tastes, metallic smells often plague tap water. Carbon filters, activated carbon, RO & post-filters improve taste & odor.
• Water Scarcity & Cost Concerns: Using clean water treatment at home reduces dependency on bottled water or water jars, saving money in the long run.

What to Look For When Choosing a System in Nepal

To pick the right system, consider:

Certifications & Safety

• Food-grade plastic tanks, certified membranes if possible.
• Proper safety valves, pressure regulation.

Water Source & Quality

• Is your water from municipal supply (e.g. KUKL)? From borewell or river? Is it hard or soft?
• Measure TDS (Total Dissolved Solids) – if high, RO is helpful; if TDS is low, maybe UV + UF is enough.

Flow Rate & Capacity

• For a household of 3-5 people, probably 10-20 liters per hour RO is enough.
• For offices or shops, higher flow or storage tanks needed.

Stages / Filtration Types

• Sediment filter (removes sand, silt)
• Carbon block (removes chlorine, odor)
• Reverse Osmosis membrane
• UV or UF (kills or filters microorganisms)
• Alkaline / mineralization (optional, for better taste & health)

Storage & Backup

• Proper sized storage to have water during power cuts.
• UV/UF backup helps in rainy or cloudy seasons.

Filter Replacement & Cost

• Filters need periodic replacement; know availability and cost in Kathmandu Valley.
• Check warranty, parts, service.

FAQs

FAQ – Frequently Asked Questions

1. Do I always need an RO filter?

Not always. If your water has low TDS (< ~300-400 ppm), low hardness, and is free from harmful microbes, a UV + UF or carbon filter might be sufficient. But many sources around Kathmandu Valley show higher TDS / microbial contamination, so RO is often a safer choice.

2. What is the difference between UV, UF, and RO?

• RO (Reverse Osmosis): removes dissolved salts, heavy metals, many chemical contaminants, very fine filtration.
• UV (Ultraviolet): kills / inactivates microorganisms like bacteria & viruses.
• UF (Ultrafiltration): filters out many microorganisms and larger particles, but not dissolved salts.

3. How often must I change filters and what is the cost?

Sediment & carbon filters usually need replacing every 3-6 months depending on water quality and usage. RO membranes usually last 1-2 years. Mineralization cartridges (if any) also need periodic replacement. We can provide parts locally in Kathmandu, Bhaktapur & Lalitpur.

4. How much water is wasted by RO systems?

Traditional RO filters waste some water. Some newer/recovery RO systems reduce waste significantly. If water scarcity is a concern, ask for “high-recovery RO” models.

5. What about after power cuts or cloudy days?

Make sure storage tanks are well insulated; include UV or UF backup; and choose systems with battery / inverter compatibility if needed.
