An endless selection of plumbing parts. Whatever I need, I’ll find it here. Often I only have a vague idea of how I’m going to do something, but being able to search through these shelves and dry-fit parts together tends to unlock solutions I hadn’t even thought of.
Then there’s also the immense calm I feel being in a space where everything is neatly organized in its dedicated places.
None. This is for a customer who wants a peace of mind. If it was my house I wouldn’t be worried the slightest. However as a professional I’m required to acknowledge that 35 year old PEX has reached it’s end of life but as a civilian I’d say it’s still good for another 20 years at least. It’s plastic after all.
Edit: Oh, and I’m replacing it with new PEX.
Edit2: I might do a pressure test on the old pipes to see how much they can still handle.
35 years?! That can’t be right.
“PEX (cross-linked polyethylene) was invented in 1968 by German scientist Dr. Thomas Engel. It was first introduced for commercial use in Europe during the early 1970s and became widely used in North America starting in the mid-1980s, initially for radiant floor heating before moving into plumbing.”
I had no idea there have been commercial PEX installations going on 55 years old now.
