Hi all,

How long will PEX pipe last when used in a central heating system?
Googling for this brings up a huge variation, from 10 years, to 100+
years, with all sorts of caveats for different uses (e.g., high
temperature use reduces lifetime to a 1/5th, etc.), so I haven't found
a definitive answer. None of the manufacturers seem to give this
information either.

thanks,

dan.
