I found this for the first time personally a few weeks ago but I’ve heard this from a few other techs and it made me aware, potential issues with some of the white insulation covered line sets when it breaks down from birds eating it or the weather and it gets wet inside it eats away at the lines causing multiple micro leaks. I was curious if anyone else has started to run into this yet, seems like a potential huge problem in our industry in the foreseeable future. #teachme
