I've heard lots of people stating that houses need re-wiring after 25 years
or so, but can't for the life of me figure out why this should be the case.
Copper tends not to corrode, and PVC stays flexible for many many years so
is this 25 year thing designed to give electricians a good earner or is
there some other reason? I'm curious as I am about to buy a 26 year old
house which has not been re-wired and am wondering what to look out for.
