Your membrane will actually tell you when it’s tired. Watch for these clues: your water starts tasting flat or a bit like tap water again. You might notice a gradual increase in your TDS (total dissolved solids) meter reading, or the system starts making more noise.
Here’s the best part—you don’t need to guess. Many systems have a flow restrictor that slows output when the membrane wears out. So if your water production suddenly drops to a trickle, that’s your membrane whispering, “Hey, I’m done here!”
DIY Tip for Maximum Joy
Want to make your membrane last even longer? Flush it regularly! Most modern RO systems have a faucet lever or an automatic flush valve—use it once a week for 30 seconds. This blasts away any buildup and keeps those pores sparkling clean.
Also, please, please don’t let your system sit for months without use. If you go on vacation, run it for a few minutes when you return to rehydrate the membrane. A dry membrane is a sad membrane.
