Why Choose a 4 x 40 RO Membrane? (The Benefits of Using This Type of Water Filter)

Okay, so I’ve been messing around with this 4 x 40 RO membrane thing, and I gotta say, it’s been a bit of a journey. I wanted to get into water purification, you know, for cleaner water at home and maybe even for some small-scale agricultural stuff I’m doing. So, I started with figuring out what I needed.

Figuring out the setup

First, I looked up a bunch of these membranes online. Turns out, these 4 x 40 inch ones are pretty popular for getting a decent amount of pure water. I decided to go with the XLP-4040 model. They say it can handle about 2300 gallons a day if your water pressure is around 100 PSI. But, since I’m just using regular city water, I figured I’d be working with around 60 PSI, so maybe a bit less output.

Getting it all together

Then I had to get all the other parts. I picked up a housing unit for the membrane, some tubing, and a few different connectors. I also grabbed a pressure gauge because I wanted to keep an eye on the water pressure going into the membrane. Once I had all the pieces, I started putting it all together. I followed some guide, and it was kind of like building with a weird set of Lego. I connected the tubing, made sure everything was tight, and mounted the whole thing on a wall in my garage.

Testing it out

Once I set everything up, I turned on the water and waited. It took a bit, but then I started seeing water coming out. I used a simple TDS meter to check the water quality. The first few gallons were a bit off, but that’s normal, they say. After flushing it for a while, the water quality started getting much better. I was getting a TDS reading pretty low, which was awesome.

I did run into a small hiccup. At one point, I noticed the flow rate was lower than I expected. I checked all the connections, and it turned out I hadn’t tightened one of the fittings enough. Easy fix, thankfully. After that, it was smooth sailing.

Results

I’ve been using this setup for a few weeks now, and I’m pretty happy with it. The water tastes better, and I feel better knowing it’s cleaner. Plus, I’ve been using some of the purified water for my plants, and they seem to be doing great.

• Started with research: Learned about 4 x 40 RO membranes and chose the XLP-4040.
• Gathered supplies: Got a housing unit, tubing, connectors, and a pressure gauge.
• Assembled the system: Connected everything and mounted it in my garage.
• Tested and adjusted: Flushed the system, fixed a loose fitting, and started getting good water quality.
• Happy with the results: Using the purified water for drinking and for my plants.

Overall, it’s been a fun little project. It’s cool to see how this stuff works and to have cleaner water at home.
