properly. Just like any other appliance, RO systems can develop problems if filters become 

clogged, membranes wear out, or internal parts stop functioning correctly.


If your RO purifier is not maintained on time, the quality of drinking water may decline without 

you even noticing it. In some cases, the machine may stop working completely.


The good news is that your RO system usually gives several warning signs before serious problems 

occur. If you know what to look for, you can get servicing done at the right time and avoid costly 

repairs later.



1. Slow Water Flow from the RO Tap

One of the first and most common signs of a problem is slow water flow from the RO tap.


When your purifier is working properly, the water should come out smoothly and at a 

consistent speed. But if you notice that it is taking much longer than usual to fill 

a glass or bottle, it may indicate that the filters inside the machine are clogged.


2. Unusual Taste or Smell in Drinking Water


Clean RO water should taste fresh and neutral. If you start noticing a strange taste, 

odor, or smell in the water, it may indicate that your purifier needs immediate servicing.


3. The RO System Is Making Unusual Noises


RO purifiers usually operate quietly. If you suddenly hear unusual sounds such 

as clicking, vibrating, or loud humming, it could be a sign that something inside 

the machine needs attention.



4. Water Leakage Around the Purifier


Water leakage is a clear warning sign that your RO purifier requires servicing.


Even small leaks should not be ignored because they may worsen over time and 

cause damage to the purifier or kitchen area.



5. The Storage Tank Is Not Filling Properly


Another common issue people experience is that the RO storage tank takes 

too long to fill or does not fill completely.


Normally, most RO purifiers fill their tanks within a reasonable time depending 

on the model and water pressure.



6. The Purifier Turns On and Off Frequently


If your RO purifier keeps switching on and off repeatedly, it may indicate a technical problem.


7. Increase in TDS Level of Purified Water


One of the main purposes of an RO purifier is to reduce the TDS (Total Dissolved Solids) 

in drinking water.


If the TDS level of purified water starts increasing, it may indicate that the 

RO membrane is no longer functioning effectively.
