As part of the maintenance of your reverse osmosis filter, you have to think of changing the filters more often. The reason is that you end up with a clean ro system that is able to filter your water easily. If the filters are not changed in time, you might end up having ro system issues such as mold and algae growing into the filters. Such are the reasons you are likely to have increased contamination in the ro system. Some people might be wondering about the process of how to change reverse osmosis filters. You would be surprised by just easy it is to end up with a clean filter most of the time.
What you will need
- Screw drivers
- New filters
Turn off your water supply
Of course, you would have connected the ro system to the mains water supply for the filtration process. Before you can go to clean and swap out the filters, you have to turn off the water supply through that route. You can also drain the water from the reserve by opening the tap. Some people end up just opening without following the right procedure, it is the reason you might just end up with a lot of water leak mess.
Sometimes you might get your ro system mounted differently to the water system. If it comes with a ball valve or saddle valve, you need to use these valves to make sure that you keep the water from flowing at the time you have to change the filters.
Release the pressure from the system (if any)
Depending on the type of ro system, it is possible that sometimes you might have one with a float valve or a ball valve. The work of these valves to turn off the water flow whenever necessary. If at the time you closed the water supply the system was full of water, it may also be still under some pressure. The closing of the valves at the input and output side always ends up creating pressure in the system. You simply have to open the output valve on the ro system to release any pressure from the system. If it is a ball valve, you can also open it to end up with a pressure free system. The pressure could also lead to water leaks whenever you take out the ro system.
Change the carbon and sediment filters
Before you can start changing the filters, it is only possible if you can get the cartridge housing the filters from the system. You simply have to unscrew the housing and then take it out for the process of changing the filters.
The first filter you would encounter would be the sediment filter. Its work is always to remove the water sediments from the water before it can continue to go through other filters. You can expect it to have the most dirt, as many particles would often collect on it. It is often white, but you would see it looking all dirty.
Make sure you have your new filters ready for swapping with the old ones. You do not have to open them until you are ready to change that particular filter. Remove the sediment filter, clean the cartridge holder with warm water before you can have the new filter installed in its place. Make sure there are no sediments in the chamber first before you can add the new filters.
The carbon blocks are the next thing to change. These filters are crucial for removing additional contaminants and chlorine that might affect the water quality. If chlorine is let to pass to the membrane, it is often seen to be destructive. The filter also helps with improving water taste, it is the reason you would find some manufacturers using two sets of carbon blocks. When you are looking to change the carbon filter, you have to arrange them from the largest to the smallest micron size.
A top tip is to always make sure that you have the filters sitting in the right orientation before you can start closing up the housing. The right orientation makes sure that the water is correctly filtered at all times.
Change the DI resin
If you are going to change the filters, you can never miss to change the DI resin too. This media is still important for those looking to end up with the best water at all times. It is crucial that it gets changed with the filters to ensure that the water is always filtered correctly. During the process of changing the DI resin, it is advisable that you make sure it is packed sufficiently. They are often two types, the cations and anions. You have to make sure they are packed in the correct order and place. If you do not have the DI resin packed correctly, you would end up with a model that does not filter water properly.
Assemble the ro system and test it
After cleaning and changing the filters, your ro system should look like new again. This would of course help boost confidence in your ro system knowing that it is now clean and it would always provide you with clean water. Now that you have changed the filters, it is time to put the housing back with the rest of the ro system. Just as you unscrewed it earlier on, you can still screw it back on ensuring that the orientation is correct too.
It should not take you long to have the product in its place. Once you have screwed it back, you can now test to see if the system is working. If the system is working, give yourself a pat knowing that you did a great job.
As you can see, the process on how to change reverse osmosis filters is not hard. You can do it on your own without having to call a plumber each time the filters have to be changed. As easy as that, you get to save some money on the labor charges and still make your ro system work efficiently.
