A note about copper, in the area I am in the water ph is a bit acid. When we built our house the local plumber said NOT to use copper. Why not it is the best we want the best we can. He says the the ph of the water will eat it out in 20 years or so and then we would need to replumb everything. we listened and did cpvc as directed. A few months after we finished our house, my Dad's house next door (where I grow up)with all copper pipeing started leaking. He has been chasing leaks bit by bit ever since, replacing little sections at a time. By the way we have been in our house 23 years now, and recently the bathroom faucet fell apart it corroded from the inside out. It was brass.
I'd bet if you looked close at your dad's house the leaks are at the soldered joints. Its Not the copper that is bad it is the "modern Almost (NO lead) solder"
I really like my CPVC although i did find one thing to keep in mins when doing repairs or modifacations to 20 year old CPVC. You need to careful what method you use to cut it. once it has been in service for a while it no longer likes the pvc cutters. You know the ones that look like a set of pruning shears. my pipes wanted to split lengthwise so i had to revert to the old hacksaw. Worked great.
I like the idea of Pex but dislike the spring loaded fittings. since my Rv sits 10 months of the year i was worried that they would not spring into action and seal up 100% when i need them for one month.
I did winterize mine a little too late in the season one time. I had to replace a 2 feet of of CPVC. The can of glue cost me more than the 4 foot section of pipe and fittings needed.
