I purchased a 6 stage Ro filter from ebay and did the install myself. I have no output from the Membrane filter to the De-orizedi 5th stage. when I took it apart I found a brass fitting on the tip of the output(not the waste line) it has a needle in the center it appears to be clogged. My water company claims 50-55 psi. I need help troubleshooting this fitting.
