What is your opinion on CPVC pipes in general?

I am asking because I am looking to purchase an apartment in a high rise building and the supply piping is all CPVC.

From previous experiences I have always preferred copper, and recently I repiped my house in PEX A. I have always considered CPVC to be "inferior" because I have heard stories of it being brittle, prone to bursting open a lot...but may be that's due to the piping exposed to sunlight? I also think I heard that some CPVC pipes on the hot side fail more frequently but that may be on some specific earlier generation brands? I know one home inspector commented once that CPVC is a "ticking time bomb", but so is polybutylene, and may be copper too if your water quality is such that will induce pin holes, and so is PEX if you bend it too much...nothing is everlasting.

Would you walk away from a home because it's all piped with CPVC? Newer construction 2007 permitted and passed inspections.

Anticipate a waterline re-pipe

".....walk away from?"

Hmmmm, for me that depends on if it's an especially great apartment at a very low price (sorry, I guess I'm not answering directly) .... as well as I'd make sure I can get good insurance as well as I'd confirm if water damage caused by pipe issues are included in my insurance.

I have seen so many hi rise condos, apartments, etc that have water heaters without a pan and we all recognize that ALL water heaters WILL eventually leak. Would I walk away from buying an apartment unit without seeing water heater pans and drains installed? I'd have the same thoughts with that.

Less than 20 years old? I'd also ask some of the people who live in the building if they've heard of or have seen any cpvc pipe issues there.

Said another way: "If I had to incur the cost to re-pipe this apt would it still be a good deal?"

'Specifcation Grade' [minimum requirements] barely code compliant crap (as in do do over later).

Kind of a conundrum because even if you repipe your unit, you're still subject to damage from units above you who haven't repiped....

its ok for cold but hot water pipes can leak especially if they bang from no expansion tank, they recently upgraded to SDR and which is thicker walled so depends how old the pipes are.
