We heard your reverse osmosis or RO water purifier is giving you trouble! Clean water is vital for health, and provided we mostly get hard water in most parts of India, let’s delve deeper into this issue. The good news is, most of your problems might be issues you can solve easily – without breaking your bank! 

This article aims to solve your RO water purifier concerns, be it leakage, foul smell or taste, blockage, loud sounds, slow water supply, or it not working at all. We have got you covered!


Troubleshooting Guide: Let’s Fix Your RO Water Purifier! 

1. Leakage Issue

Leakage Issue

Your water purifier might be making small puddles of water around, and you do not know why. The purifier system parts might be loose or not correctly inserted. Alternatively, the pipe might be clogged. A simple tightening of the line can help if you have a tool to fix pipes! Otherwise, if this does not help, call your local RO technician.


2. What’s that smell?

Are you dealing with water that has a foul odor and funky taste? Water that’s not entirely filtered is to blame.

o Chlorine or salt residues can cause a weird taste in water.

o Metallic taste means the water has metal residues such as sulfate, copper, and zinc, which can happen with RO purifiers as they use copper for tubing.

o Clogged filter means contaminants are attached to the filter adding foul smell or taste to otherwise tasteless water!

Deep clean the filter or replace it! Ozonisation of water also helps.


3. Muddy Colour

Muddy Colour

Dirty, brown, or water that is greenish is not safe to drink! The cause can be metal residues such as sulfate, zinc, or other impurities usually found in water. Muddy water is not safe for consumption.

Copper can make the water turn mossy green which can happen with RO purifiers as they use copper for tubing. Ensure you empty the water storage entirely and then start using the filter after checking the issue!


4. New filter

New filter

Did you buy a new filter, but your cleaner is suddenly not working? Hold on! Your new filter is probably incorrectly attached. Make sure you have cleaned the opening of the filter point for a smooth flow of water!

Try using your old filter to see whether the problem is the new filter or something else. You can do this yourself or ask someone in your house for help before calling a technician.


5. Slow supply

If your water purifier takes double the time only barely to fill your glass, then the problem can be pressure or blockage! The minimum pressure needed for a water purifier to work well is 40-60 PSI (pounds per square inch). Low pressure causes a slow supply of water.

If you have a pressure gauge handy, you can fix this issue yourself. If the pressure isn’t the problem, check your filter for blockages that might be obstructing the flow of water.


6. Odd, loud sounds!

Odd, loud sounds!

Is your water purifier suddenly sounding like a washing machine? While water purifiers generally make a little bit of sound as they work, they should not be the loudest sound in the house.

If you’ve changed the filter recently or just purchased the water purifier, give it some time. If the problem persists, check the filter and possible air blockage. Your tightening tools will come to the rescue.


7. No beep or water!

If your LED light isn’t working and you cannot hear the classic purifier beep, it doesn’t mean your water purifier has stopped working forever. If there’s no water flow, the filter might have serious blockage issues. Things to try:

  1. Change the plug point to see if that plays a part in this problem.
  2. Check carefully if any switch is off!
  3. Try starting your purifier after a break.

There can sometimes be a more significant issue, for which you’ll need a professional’s help. 


8. Overworking Purifier

Overworking Purifier

Sometimes, there’s a glitch in your cleaner, and it might not stop working and end up (possibly) flooding your kitchen. In this situation:

  • Patiently switch it off, in case you’ve been pressing the ON and OFF buttons in panic.
  • Switch the main power supply off, and when the issue persists, check for problems with the switch or filter.
  • Check for a broken filter or any other fissures in it. You have to replace the filter or other damaged parts of the cleaner.

Tip: Buy the parts that need replacement yourself while contacting a professional for help, as they overcharge! 


9. Did you clean your purifier?

A clean filter is a filter that works well. Make sure you clean the filter so that other problems don’t occur, as this is the root cause of complexities for most RO purifier issues.

Since water in the country has more Total Dissolved Solids (TDS), also known as hard water, it means you have to change the water filter every 2-6 months or impurities are likely to make the water quality poor and cause other issues that we have mentioned in the article.

We have gathered that checking and cleaning the filter for blockages can solve most of your RO purifier issues. If not the filter, it can be the pressure or plug point. The next time your water purifier gives you trouble, you know how to solve it and when to contact an RO technician!
