The reverse osmosis system is great for water purification, but it won’t be able to do its job consistently if filters are not replaced every now and then. In an average system, prefilter and postfilter replacement must be done every 6 to 12 months to ensure water quality.
Before anything else, the system must be shut off by turning off the water supply and closing the valve that controls the flow. The following are the next steps:
- The faucet where the filtered water comes out must be opened to relieve the pressure.
- With the help of a wrench, open the filter housing.
- Discard used filter cartridges properly. Make sure to remove excess sediment from the cartridges before throwing them away
- Clean the housing interior by scrubbing it with a soft bristled brush and warm soapy water. Rinse well.
- Remove the O-rings and clean them by wiping. Replace them if necessary.
- Insert the new filter into the filter housing.
- Screw the housing back into place and make sure it’s secure.
- Turn on the water supply and valve to test for leaks. This will also provide the system’s interior a final rinse.
Replacing the filters is essential so knowing how to do it is really helpful. Apart from filter replacement, it is highly advised to clean and maintain the whole reverse osmosis system once a year.
