5 Easy Steps To Maintain A RO Water Purifier

RO water purifiers can be found in every house hold these days. While it important to pick a quality water purifier for your home, it is even more important to maintain it properly so that it continues to provide you safe and healthy drinking water and last for a long time.

In this article we will enlist 5 mportant steps that you must follow to keep your RO water purifier efficient and in good condition. Lets start..

1. Change Filters on Time

Water purifiers use several filters to purify water. Depending in the quality of input water and water consumption, these get clogged with impurities in 6 months to 1 year. This is when you would need to change them.

Below is the standard replacement schedule for the common water filters.

  • Pre Filter : 3 to 6 months
  • Sediment Filter : 12 months
  • Pre-RO Carbon Filter : 12 months
  • UV bulb: 12 months
  • Post-RO Carbon Filter or Polishing Filter: 12 months

As you can see, most of them will need to be replaced at least once a year. Some latest water purifiers also come with LED indicators or alarms to alert you when you may need to change these filters. It is a great convenience and one should prefer purchasing such machines.

Prefilter needs to be changed every three to six months and you can check and change it yourself as shown in the video below.

2. RO Membrane Replacement

The RO membrane is a semi-permeable membrane that helps in removing high dissolvable solids (TDS) from the water. In this process, it absorbs a lot of impurities and in 1 to 3 years (depending on quality of input water and water consumption) it will start smelling foul. This is the time to change the RO membrane. Because RO membrane is the most critical part in a RO water purifier, it is important to replace it without delay so that you continue to get pure and safe water to drink.

3. Fix Drips and Leakages

It is common for water purifier pipes to start leaking in few years. When it happens, fix them quickly as not only it wastes water, it can invite growth of moss and other microorganisms inside the pipes.

4. Sanitize Storage Tank & Connection Pipes

When you are getting your filters replaced, insist on getting the water tank and connection pipes sanitized as well. Also you should drain out the water that has been stored in the tank for more than 48 hours, as it becomes unfit for consumption.

5. Clean the Purifier’s Body and Tap

Cleaning the external body of a water purifier doesn’t affect its performance, still its a good idea to clean it thoroughly. More importantly, if your water purifier has a tap, make sure to sanitize it every day as it is exposed to the germs in the enviornment.
