Have you ever taken a sip of your RO purified water and felt a strange bitter or metallic taste? You’re not alone. Many households using RO water purifiers in Bangalore experience this issue from time to time.
And while you may think it’s just your taste buds acting up, the truth is — your water purifier might be trying to tell you something.In this blog, we’ll explain why your RO water might taste bitter or metallic, what causes this problem, and most importantly, how to fix it. Plus, we’ll guide you on when to search for water purifier service near me, Kent RO service near me, or Aquaguard service near me to get professional help.
What Causes Bitter or Metallic Taste in RO Water?
Let’s break it down step-by-step.
1. High TDS Levels in Input Water
TDS stands for Total Dissolved Solids. While RO systems are designed to reduce TDS, if the source water contains excessively high TDS, your purifier may not be able to remove all the impurities — especially if the filters or membrane are old.
2. Worn-Out RO Membrane
Over time, the RO membrane becomes saturated and loses efficiency. This can lead to improper filtration, allowing unwanted heavy metals like iron, copper, or lead to pass through — causing that metallic aftertaste.
3. Clogged or Expired Filters
If you’ve skipped your regular Kent water purifier service or Aquaguard service, chances are the pre-filters and carbon filters are clogged. This can affect the overall taste and even cause bacteria buildup in the system.
4. Lack of Mineral Retention
RO purifiers often strip away essential minerals along with contaminants. While the water is safe to drink, the absence of calcium, magnesium, and potassium can leave it tasting flat, bitter, or even metallic.
5. Rusty Plumbing or Old Storage TankSometimes the problem isn’t in the purifier but in the pipes or tank connected to it. Rusted pipes or an unclean storage tank can leach metals or odors into the purified water.
How to Identify Bad Tasting RO Water?
Here’s how to understand the specific taste and what it might mean:
| Taste | Possible Cause |
| Bitter | High TDS, chlorine residue, expired carbon filter |
| Metallic | High iron, copper, or zinc; old RO membrane |
| Fishy or Sulphur-like | Bacterial contamination or ion exchange resin breakdown |
| Plastic taste | New purifier system or degraded internal components |
How to Fix Bitter or Metallic RO Water Taste?
1. Get a Professional Water Purifier Service
If it’s been more than 6 months since your last check-up, it’s time to book a water purifier service near you. Whether you own a Kent, Aquaguard, or Livpure purifier, regular maintenance is essential.
Just Google Kent RO service near me or Aquaguard service near me in Bangalore, and you’ll find certified technicians who can:
- Replace worn-out filters
- Clean the RO membrane
- Sanitize the storage tank
- Test the TDS levels
You can also book a technician directly from a reliable water purifier shop near you if you need quick assistance.
2. Check and Replace Filters Regularly
Here’s a simple schedule to remember:
- Sediment Filter – Replace every 6–8 months
- Carbon Filter – Replace every 8–10 months
- RO Membrane – Replace every 1.5–2 years
- Post Carbon/Mineral Filter – Replace every 12 months
Missing any of these could compromise both taste and safety.
3. Install a Mineraliser
A mineral cartridge or taste enhancer helps restore lost minerals in the purified water, balancing the pH level and improving the flavor.
If your purifier doesn’t have one, consider upgrading. Many advanced Kent and Aquaguard systems now come with in-built mineralisers.
4. Clean the Storage Tank
Even if your purifier is working fine, stagnant water in the storage tank can develop odor and taste over time. It’s important to clean your tank every 2–3 months.
This is often included in professional water filter service near you, so don’t skip it during your routine maintenance.
5. Test Your Source Water
Sometimes, the problem lies in the input water supply. High iron content or salinity in borewell or municipal water can affect the purification outcome.
A local technician from a water purifier shop near you can conduct a TDS test and suggest solutions such as:
- Additional pre-filters
- Anti-scalant cartridges
