I simply replace the pipe with a new one.

I never had trouble with the ice in the winter. I believe it freezes inside as well as outside the pipe so there is even pressure, preventing the pipe to burst.
BH: I think the fact that you are replacing the pex pipe every several years indicates you are using the wrong material........
