When it comes to purifying water with a high number of total dissolved solids then Reverse osmosis is one of the best water purifying systems to rely on. This technology works by separating dissolved and suspended particles from the water with the help of a semi-permeable membrane called the Reverse Osmosis membrane that works under high-pressure conditions.

The impurities that a RO membrane goes through each day like lead, fluorides, magnesium salts, calcium, iron, arsenic and much more cause great harm to your health as well as your RO membrane. These type of matters are mostly found in groundwater and if it happens to be the source of water for your RO system then it is something you need to worry about as the RO membrane is the most critical part of any reverse osmosis system. As it is a thin film that is made up of microscopic pores, it can get contaminated by biological matters, minerals, suspended organic contaminants, and other particles.

Not only this, due to all the particles getting blocked up , the membrane will not be able to effectively remove the salts from the water. This is the reason why you need to take care and remind yourself to change the RO membranes on regular basis. But the question arises, when is the right time to change your RO membrane?

In this article, I will be giving you some tips to know when it is the right time to replace your RO membrane. Below are some situations that you need to keep in mind and if you face any of the problems listed below, it may be a sign that you need to replace your membrane now.

Check the Water Pressure

Check the pressure of your water as low water pressure is a clear sign that there is some problem with your RO water purifier system. Water pressure below 40 psi is an indication that your RO membrane needs to be replaced.

Taste and Smell your water

When you find out that your water is not tasting or smells as good as it used to be, then there is some issue with your water purifier. A bad taste or smell is often due to a bad membrane or an expired filter and can be fixed easily with a replacement.

Check the TDS levels

Apart from that you can also test the hardness of the water and total dissolved solids to determine whether the membrane is functioning properly. You can check in the amount of TDS in water with the help of  any good TDS tester available in the market. Make it a habit to weekly test your water for tds levels and if it drops below 80% then it is the right time to replace your RO membrane filter.

Wrapping it up

Every element of your reverse osmosis water purifier requires periodic maintenance so as to get the same quality of water even if years pass. The most important step of maintaining your RO system is to timely replace your RO membranes. Don’t wait if you are not facing any of the listed problems and make sure to change your RO membranes every 2-3 years for the better functioning of your RO water purifier system. After all, it is all about drinking clean water.
