Maintaining Your RO Water Purifier

RO water purifier maintenance

The reverse osmosis (RO) system uses a multi-stage filtration process to remove different types of contaminants from water. The water purification system uses a thin membrane to remove salt, chemicals, and impurities from water to make it safe for consumption. The contaminated water passes through this thin membrane (a polymer film) with very small-sized pores. The membrane weeds out minerals and microorganisms present in water. An outlet pipe flushes out the impurities. However, to ensure that you get clean and safe drinking water, you need to properly maintain the water purifier. Without proper maintenance and care, the water purifier will not function properly and you may end up drinking contaminated water. So, in this blog, we discuss a few tips that will help you maintain the RO water purifier. Read on.


How to Maintain RO Purifiers and their Importance

RO water purifiers play an essential role in removing different types of impurities from water. The additional filtration stages remove impurities of various sizes to make water safe for use. This is the reason why maintaining RO filters is a must so that the water purifier works without any glitches. A reverse osmosis system consists of three stages-pre-filter, reverse osmosis, and post-filtration. The pre-filtration stage separates sand, silt, and other residual particles from water. The pre-filtration stage is important to keep the RO Membrane safe from damage. Not changing the pre-filters might damage the RO membrane and the water purification process may also be affected.

1. Maintaining the RO Membrane

In the reverse osmosis stage, water is pushed at a pressure of 35 psi in order to pass through the membrane. The thin RO membrane separates out the solutes from the solvent and only pure solvent is allowed to pass through it. As the RO membrane is a central part of the water purifier system, maintenance, and regular cleaning is of utmost importance to ensure that you get clean, safe, and tasty drinking water. The RO membrane needs to be changed every 3-4 months in order to prevent clogging pores.

2. Regular Filter Changes

The filter of an RO purifier needs replacement after approximately 3 months. The reason is the contaminants from water clog the filters after a short span of time. Not cleaning the water purifier frequently will affect its filtration capacity and the quality of the water. If you continue using filters without changing them, the impurities are transferred to the water you drink. As RO water purifiers have at least three to twelve stages of purification, it is important to schedule the filter change on a regular basis.

3. Sediment Filter

RO water purifiers use multiple filters to remove impurities present in water.  One of the filters used by the RO purifier is the sediment filter. Change your sediment filter at least once a year. Maintaining your sediment filter helps in staining out sediment, dirt, and slit. It protects dirt from getting to the fine RO membranes.

4. Carbon Filter

You also need to change the carbon filter once a year. A carbon filter removes chlorine and other dangerous contaminants that affect the life and performance of the RO membrane. The filter also has an impact on the taste and odor of the water you drink.  (Source: Home Design With Style)

5. RO Membrane Replacement

RO Membrane

RO purifiers come with a semi-permeable membrane, which allows water to pass through it but filters out all additional contaminants. For optimal performance, you need to replace the RO membrane every two-three months. However, keep in mind that this schedule is totally based on the quality of water and household water usage.

6. Drips And Leakages

In case you notice drips or leakages, don’t forget to get the help of a professional. Leakages in a water purifier can create a lot of problems if you don’t take the right steps. Ask the professional to thoroughly check the water purifier to know the cause of the leakage and save the machine from damage.

7. Sanitize Your RO Tank

You also need to clean the pipes of the RO system regularly to make sure the water purifier works perfectly. Sanitizing the RO tank can help you maintain the purifier and keep it in a good condition. For best results, sanitize the RO tank when you replace the filters.

8. Annual Maintenance

To avoid any serious problems with the RO purifier, make sure that you get the help of a professional to replace the filters. Renowned brands such as KENT provide annual maintenance contracts (AMC) which is an easy and convenient way to maintain the appliance.

Summarizing the Process

  1. Replace all the filters annually or at the max of 12 months
  2. Replace the RO membranes annually
  3. Sanitize the water storage tanks
  4. Make sure to clean and sanitize the pipes every 2 years
  5. Replace and buy any new parts when necessary
  6. Check the pressure nozzle at regular intervals
