Where to Buy RO Membrane Replacement? Best Options for Quality and Price!

Okay, let’s talk about the RO membrane replacement I did the other day. It wasn’t too bad, but definitely something I took my time with. I have this under-sink water filter system, and the water was starting to taste a bit off. Figured it was time to swap out that membrane.

First thing I did was shut off the water supply to the system. You don’t wanna forget that part, trust me, I’ve done this, but I’ve never had this situation. Then I grabbed my tools. Nothing fancy, just a wrench to disconnect the water lines and a screwdriver to open up the membrane housing.

• Shut off the water: This is a must!
• Gather tools: Wrench and screwdriver did the trick.
• Disconnect the lines: Take your time.

Next, I carefully disconnected the water lines from the membrane housing. There were three of them: the inlet, the outlet for the filtered water, and the one for the wastewater. I made sure to keep track of which line went where. After that, I unscrewed the cap of the membrane housing. It took a little elbow grease, but it finally came loose.

I pulled out the old membrane. It’s always interesting to see how gunked up these things get. That means this thing working well. Honestly, it looked pretty nasty, so I was glad I was replacing it. Then I made sure the new membrane, I chose a 100 GPD one because it seemed like a good balance of flow rate and efficiency, fit snugly inside.

Putting everything back together was basically the reverse of taking it apart. I tightened the cap of the housing, reconnected the water lines, and slowly turned the water supply back on. This step should be careful and keep patient to get things done. Checked for leaks, and luckily, there were none. The first time I did this, I messed up and had a mini flood under my sink, so I was extra careful this time.

I let the water run for a few minutes to flush out the new membrane. The instructions that came with the membrane, oh by the way, I got this one online, a well-known brand, recommended doing that. It is said that the choice of the series of RO membranes should be based on the requirements of the end-user for desalting rate, operating pressure, pollution rate and cleaning frequency, and the quality of the influent water. And then I tasted the water. Much better! It was clean and crisp, just like it should be.

Maintenance tips

I know some people say you should replace these membranes every 3-5 years, but honestly, I do it more like every year or two, depending on how much water we’re using. And it’s better to be safe than sorry when it comes to drinking water, right?

All in all, it was a successful little project. Saved some money by doing it myself instead of calling a plumber. Plus, I got that satisfaction of knowing I did it myself. If you’re thinking about replacing your RO membrane, go for it! Just take your time, double-check everything, and you’ll be fine.
