It took my son. 2 years to talk me into using Pex. I was a copper man, through and through ! Then after using it while helping a friend with a job he was roughing, and he used it. I was amazed, but still it took a couple situations where my son would say, "Dad wouldn't it be so much easier, with Pex right now ?" Well, I plunged, bought the Rigid Propress 200B, with the Propress Jaws and ViegaPex Jaws(still like to see at least brass on a plastic water pipe fitting). Except now I have a couple thousand copper fittings, that are sitting on my shelves. Use a "street" fitting now and again with the Propress. My shop was started in 1933. You can imagine what I have. I have fittings that you wouldn't find in any supply house. Some definitely interesting copper fittings, 4" and down. Then there are the Plumbing Museum fittings. Anyone know what a "Kennedy Tee" fitting is ? Have 2 of them. Never ever used one, (not quite that old) . I seriously have a lot of respect for the guys that used to have to cut and thread, water and galvanized drains and vents. Besides running 4" cast iron stacks, and pouring lead, for every joint !! It has been a while since I poured "my" last one. Another one, for the younger guys, a Kafer fitting ?? (You want to make sure, you only use "one" "F" when spelling it !!)
