A water purifier is a necessary home appliance for all households, but it has some common issues when you are using it. First, you have to know about common RO water purifier problems.

An RO water purifier protects you from the problem of drinking dirty water and gives you clean drinking water from which you can live a healthy life without taking medicine.

When a water purifier gets older than 6 months, its filters start getting spoiled, and you will face dirty water problems, smell in water, RO not working, etc.

This all signs telling you to change filters and clean and maintain the whole purifier. So in this blog, you will get all information about common RO water purifier problems, and it’s solution.

How does an RO Water Purifier Work

Water purifiers work on many stages that clean water properly, and their supportive components work very well his job.

To understand the full process of the purification system need to know about all the filtration parts of an RO water purifier.

Main Components of an RO Purification System

For the step-by-step purification process, Ro need some filters like:

• Pre filter
• Sediment filter
• Carbon filter
• Membrane
• UV, UF filter
• Alkaline cartridge
• Storage tank

They all work together to make water drinkable, reduce TDS, and remove all impurities.

Role of Filters and Membrane

All basic filtration parts make water clean easily. Filters remove all types of harmful bacteria and viruses and help the membrane function properly.

All filters make the membrane work easily and protect it from getting spoiled. The membrane plays the role of removing high TDS from water.

Why RO Systems Need Maintenance

Because all filters inside store all impurities of water and get spoiled; that is the reason for maintenance of an RO system.

If you want to drink water for a long time, then you will take Care of maintenance time; otherwise, the purifier’s water taste will tell you everything.

This was your question’s answer on how an RO water purification system works. I hope you will like this information and should be helpful.

Common RO Water Purifier Problems and its solution

Common Problems	Possible Causes	Quick Solution
RO not dispensing water	Low pressure or clogged filter	Check pressure and replace filters
Slow pure water flow	Blockage of membrane	Replace membrane; it is best
Water leakage	Loose fittings	Tight connectors and fitting
Bad taste and smell	Expired carbon filter	Replace carbon filter
Continuous water wastage	Fault auto shut-off valve	Replace auto shut off valve
RO loud making noise	Pump issue	Change Pump or it head
Tank not filling	Low pressure of pump	Check pump
TDS high above 150	Membrane problem	Replace membrane
RO not working	Power supply issue	Check SMPS adapter and switch
Frequent filter choking	Dirty water supply	Install pre filter set

It was a list of some common problems that you can fix easily with solutions, so apply them and save money.

Purifier not dispensing water.

When water flow doesn’t reach the storage tank, then it is a water not coming problem. This is a common problem; it can be resolved easily.

Causes of it

• Low pressure of water
• Sediment filter blocked
• Faulty booster pump
• Inlet valve closed
• Full water storage tank

Solution

• Check the water supply from the tap and check the water input valve; if block then clean it.
• The sediment and carbon filter is most important to check because after every 6 months it gets spoiled.
• Water pressure check because Ro system needs 40 to 60 PSI to function properly.
• Check Booster pump functioning: if the pump is not vibrating, no humming sound, and delay in filling, then change the pump.

Slow water flow from RO

Usually, slow water problem create because of sediment and a clogged carbon filter, a clogged membrane filter, or low pressure. To fix it, check all of these.

Common causes

• Choked pre-filters
• Chocked membrane
• Poor pipe connection
• Low pressure of storage tank

Solutions

• Flush RO membrane to remove impurities, or replacing it is the best option.
• Replace filters
• Check pressure if required, then fill it.

Water leakage problem

First find the actual leakage area, then take a solution. Like pipe joint, tap, filters Lbow, faucet, tank, membrane housing.

If the fitting is loose, tap water leaks, housing chocked and loose pipes.

Solution

• Fix fitting leakage; change O-ring rubber.
• Tighten the tap if the leak is from there.
• Replace housing if choked.
• Push the pipe properly to fix pipe leakage.

Bad smell and taste problem

Smell is normal in a water purification system because every 6 to 12 months, filtration parts get spoiled, which becomes the reason for bad smell.

Cause of it

This cause is created by a clogged carbon filter, which is responsible for bad taste and smell.

Solution

Simply change the carbon filter and fix it. Carbon should be of good quality.

Continue water wastage

Water wastage is a process of the purification system, but if water is wasted too much, then you should take action.

• Check the float valve; it is responsible for auto cut
• Check the SV; if not working properly, then change it.

RO making sound

RO doesn’t make sound, but if it happens, then you should check the cause and fix it early. Mostly the pump make noice it booster pump make notice, then change it or repair it.

Tank takes time to fill.

For tank filling problems, check water pressure. If water pressure is perfect, then you should check the membrane filter.

High TDS level

TDS (total dissolved solids) level matters for health, so take care of Tds level if Tds level high of water, then you should change the membrane filter to fix it because it is used to reduce the TDS level.

A drinkable TDS level of water is 50 to 150ppm. 150 to 300 ppm is acceptable but not for a long time, and above 500, don’t use it to drink as per WHO guidelines. All information from WHO guidelines.

RO not working

This is one of the common RO water purifier problems: if the electrical power supply of the purifier, the SMPS adaptor, is not working, then change it and check the power supply.

Second reason: booster pump not working; then RO will not work, so change or repair it.

SV problem: if the SV is not working, then it should be cause of purification process is not working, so check it if not working.

Early filters choking

It totally depends on water quality; if your water is very dirty, then it can block all filters. If the water is safe, then use good quality filters.

So check row water quality before install an Ro water purification system.

These are 10 common RO water purifier problems. If you are facing any problem, then I have told you the solution in this blog; follow it and do it for yourself.

Diy maintainence tips

I am telling you some maintenance tips for your water purification system’s health. You can follow them and be safe from expensive service and maintenance costs if you don’t want to face common RO water purifier problems.

Monthly maintenance tips

Here are some tips for you that can help you to manage your water purifier on a monthly basis.

• Clean the outer body with water or a cleaner that in insure dust is removed.
• Check the pipe fitting of the water purifier’s inner side.
• Check for leakage of the RO system because it common Ro water purifier problems in one of problem.

6 months tips

• After every 6 months, filter replacement is important; then replace sediment and carbon filters.
• Sanitize every part that is available in the water purification system.

Yearly maintenance tips

• Full service of the water purifier is important after 1 year.
• Membrane replace if not working properly; it is important because membrane life 1 year.
• Check the TDS level of water and maintain it by adjusting the TDS controller.
• Check that the pump works properly and has no issues, then change it.

These were some tips to maintain a water purification system. Follow these and keep away from common RO water purifier problems.

Replacement and repair are beneficial.

Some problems can be fixed after repair, but some common RO water purifier problems cannot be fixed with repair. In this condition, replacement is more important then replace part.

Next, see some situations of common RO water purifier problems and get suggestions on which is best.

Situation	Repair	Replacement
Minor leakage	Yes	No
Old membrane	Yes	No
Repeated PCB failure	No	Yes
Tank damage	Yes	No
Purifier older than 7 years	No	Yes

If you feel the repair cost is expensive and charge 50% amount of new part, then replacement is the best option.

When you should call professional technician?

When you face multiple common RO water purifier problems in RO, then you should take action and call a professional technician and take advice from him. If parts are damaged or repairable, then replace parts at a reliable price.
