How to Tell if RO Membrane is Bad (6 Obvious Signs)
The RO membrane in a reverse osmosis system lasts longer than the other filter stages, but it’ll still eventually need to be replaced.
In this guide, we’ve shared the 6 signs to look out for that suggest your RO membrane is bad.
The average lifespan of an RO membrane is 2 years.
Reduced flow rate, poor water taste or smell, membrane discoloration or cloudiness, lukewarm water, and elevated TDS are all signs that the membrane needs to be replaced.
Make sure the membrane specifically is bad, and not one of the other filters. Inspect the entire system and check the appearance of the other filters, too.
