Hi folks! My first post here.

I need professional plumbers opinion on this. I know these questions can harbor more then one simple answer, but that is what I am looking for and the reasons behind the answer(s).

Question 1 is:

In your opinion, what would you think is number one cause of a brand new 3/8" - 1/2" compression adapter failing in under a years time?


Question 2 is:

In your opinion, what would you think the average life expectancy of a brand new 3/8" - 1/2" compression adapter would be under normal conditions?


I hope these are legit questions to ask here and if not I apologize. I am doing some research and need professionals opinions. Thank you ;-)


peace out,
