I bought a house to flip. It was a partially finished new house
dried
in, supply plumbing was finished and inspected. They look like
thay
did a good job except the CU pipe in the basement is fastened
directly
to the concrete walls. Is there anyway this could be OK? The
rest of
the house is plumbed with PEX.

Generally copper does not have problem with concrete and I have never
seen *a problem with copper & concrete in SoCal installation. *My pro
plumber does put some sort of "insulating felt" between copper &
concrete.

per the copper org link...........

"According to the Portland Cement Association the interaction of
copper with both dry and wet concrete should not cause a corrosion
concern. However, copper should be protected when it comes in contact
with concrete mixtures that contain components high in sulfur, such as
cinders and fly-ash, which can create an acid that is highly corrosive
to most metals including copper."

so maybe standard procedure now is to protect copper from concrete
just in case the concrete is of the corrosive type?

I guess that would mean cinder block. The guy that plumbed the pipes
did an excellent job of soldering and arranging the pipes. It was
plumbed for water heater, softener and some other type of filter.
There is a place for laundry but there is also one upstairs. I pulled
the pipes loose from the wall and painted the basement last night. My
plan is to highlight the workmanship that done here and on the
distribution manifolds by polishing and lacquering the copper and
mounting it on cable clamps meant for coax cable. Normally these
clamps are failry expensive but for me they were just some "come bys".
My real estate lady says things like this really add to the
saleability of the house, something that will be needed in this
market. She also cautioned me on changing things after they have been
inspected. Ooops.

There is one thing Im curious about, The connections into the
manifolds were done in PEX. These pieces are only a couple of ft
long. Is this an expansion joint or did he build the manifolds in his
shop then just splice them in with PEX?
