I had a house with the plastic stuff, circa 1999.
Max pressure was 40 psi, I think it is higher now. You will need a
pressure
regulator.
Any monkey can install it with the right tools and 10 minutes of
instruction. I have heard the tool is not exactly what a home owner want
to
buy.

As long as the 40 psi was the limit I would not be interested.

I will take that as a you would rather have copper. Now the any Monkey
thing got me thinking so I looked some information on installation, I can't
find anything in English
