PEX is easier to install, therefore saving you money. Some people are
still terrified of PEX, due to an issue with an entirely different kind
of pipe (poly) in the 80's. It's actually more resistant to bursting
from freeze than copper.
Copper causes cancer, according to Effi. Other than that, I'm not aware
of any downside to copper, other than it bursts easily when frozen.
I'd guess in another 10 years or so, copper will be phased out
completely in the mainstream.
Having said that, were I building a new house, I'd choose copper. No
real reason though, other than that's what was in my parents house, and
has been in every house I've ever owned. I don't need any new
inventions from you young wippersnappers.
I would have to agree with almost all of that. While I would go with
copper today, (I would like to see more history of wide use of PEX before I
would want that.) but my parents house was galvanized pipe as was my first
I wanted copper on my new house, instead builder choose to
install Wirsbo Aquapex Tubing.
I am glad they did. Love it. We had our old house replumbed
with copper about a year ago. Should of used pex. It is great.
Only issue I have is the tool to work with it is way too expansive...
And can't seem to find any rental place that has it...
I have been building homes for over 20 years and I can think of no
real-world characteristic of copper that is superior to PEX. I have
not used copper supply lines in a home in eight years.
PEX is tough, easy to install, and it can endure freezing much better
than copper. I have never seen a PEX pipe burst from freezing.
My house has plastic water piping.
The only down side is that I can not set the water pressure regulator higher
than 40 psi. Showers are not what they used to be even with removing the
restrictors. Back yard hose works but lacks the pressure of the front one,
ahead of the regulator.
If the builder had used a larger pipe to the shower I would have no issues.
I like hard and large volume showers, like standing under a water fall.
