Easiest way to attach this HDX inline filter to replace my American Plumber WICA inline filter
I was able to take off the plastic connectors on each end of copper. After that I realized since ther were push to connect then I could use push to connect on copper as well as flex line. At that point I cleaned the copper ends with a green 3m scouring pad, and installed the filter with no soldering and none of the brass parts.
