PEX A vs. PEX B
I am obsessing over which pex to use for a whole house manifold installation. The choices are pex-a (uponor) vs pex b (viega).
Uponor seems easier to work with, less kinking, better flow etc.
What I am most concerned with is:
1.longevity (this is my forever house)
2. safety (leaching of chemicals into drinking water)
I am on a well.
Any input as to the longevity and safety of these two different types of pipes?
