Installing an RO membrane housing can be simple and quick if you have the knowledge and proper equipment.
If you’re looking to install one in your home, this article provides a simplified step-by-step guide that’ll teach you all you need to know about the process, starting with gathering the right tools…
Let’s go!
Key Takeaways
Follow these steps to install an RO membrane housing:
So, how do you connect the housing of an RO membrane to the rest of a reverse osmosis water filtration system?
For this simple installation, you’ll only need the following:
You will also need needle-nose pliers in case you want to install a new RO membrane and possibly a membrane housing wrench in case the housing cap is stuck.
The first step is to attach your membrane housing clips to the system module/bracket or any other filter housing you may want to connect to your RO membrane to. These housing clips will help keep your membrane housing in place.
Next, you can mount your RO housing onto the clips. Be sure to attach it carefully so that it’s securely in place.
After mounting the housing safely, you must connect the necessary tubing. To do this, you’ll need to do the quick-connect fitting correctly.
These quick-connect fittings have a locking mechanism used to keep the plastic tubing connected to them providing a watertight seal.
Before connecting the tubing to the membrane housing, ensure it’s cut smooth and straight around the edges. If the mouth of a tube has burrs, it may end up damaging the O-ring inside the fitting as you push the tubing inside. To counter this, lay each tube across a flat surface and cut it evenly to create a smooth and even edge.
Once you’re done, mark each end of your tubing at about the three-quarter-inch line. This is important because a fitting can only be watertight when the tubing has gone into the collet and past the O-ring. Sometimes you may push the tubing in, and it’ll feel like it’s clicked in place even when it hasn’t. However, marking the end of your tubing helps you know when the tubing is in place because the marked area will disappear into the collet.
So after you’ve marked each tube, carefully push them into their respective fitting, at least until the three-quarter line you drew or until it snaps in place. Test how tight the connection is by trying to pull each tubing out. If it doesn’t budge, it’s tight enough.
In the end, there should be one tubing connection to the pre-filters (tubing connected to housing cap), one to the drain, and one to the RO tank or post-filtration.
If you want to disconnect any tubing, hold the outer clip of the collet, push it in, and then gently pull the tubing out.
If you also want to install a new RO membrane, do so before connecting the tubing to the membrane housing cap.
The installation process is simple:
