Yep, it cheap, and works great as a temporary garden hose.
When I do plumbing, I want real pipe which will last many decades.
Whether it's copper, brass, or galvanized iron. �I get a laugh with
these trailer homes they use this PEX and since trailers have cheap
skirting, rodents live under them, and feast on PEX and Romex.

My home has galvanized pipe coming in from the main, installed around
1950 and it still works fine. �I replaced all of the hot water pipes
with copper in the 80's and replaced the cold pipes at the fixtures at
the same time because the walls were open. �I can use the galv pipes
to hang stuff, without worrying about some kid ripping the pipes down
and causing a flood.

PEX is about the same thing as plumbing your home with garden hose.
You wont ever find it in my house, as well as the CPVC. �I installed
CPVC to an outdoor spigot in the 90's a few years later it snapped off
at the wall during a cold spell. �GOOD plumbing is METAL. �CHEAP
plumbing is PLASTIC. �

Of course these days, new homes are only built to last 20 years, so
the plastic pipes are fitting.

Question: Have a 3/4" copper to galvanized pipe junction, has a 6" brass

copper sometimes gets attacked by water and leaks insde walls etc....
PEX doesnt have that problem and can stand repeated freezing and
thawing
