Would you have any quelms using expansion on zurn pex that's had chlorinated water for 3yrs?

I'm doing some repairs and installs of new fixtures. House is 3yrs old in phx area, with zurn pex expansion fittings. I'm on chlorinated water and wonder if I should not risk expanding at this point, and go with copper crimp rings? Could the pex be more susceptible to splitting at this point? What would you do?

From what I read so far it shouldn't be a problem especially if the pipe hasn't been exposed to UV light. But if the fitting is accessible for a crimp tool I would probably just do that if you have the tool.

I think three years is well within a window that I personally would feel comfortable expanding, but I would probably *warm* up the pipe before expanding (warm, not hot ). I think a nice warm pipe would have much less chance of enduring some stress while expanded.

I would also consider a whole house chlorine filter for any pipe, including today's copper.
