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.


You definitely have too much time on your hands.


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.


I'll bet I could find dozens of other things that would add to the
appeal of a house long before polishing and lacquering water pipes in
the basement. * Also, I would never lacquer a copper water pipe
because if you need to repair, tap into it, expand, etc, you will be
using a torch on it.


Yep, at the time I did have a lot of time on my hands so why not use
it constructivly. Touches like this may not add value to the house but
they may help it sell quicker. Also a little lacquer is no problem at
all to remove. The electricians came in this AM and they were
impressed with it . It impressed them enough to be careful around it
and if it impressed them enough to inspire them to do good work it
will have been worth it. From the conversation I overheard I believe
it did. Maybe when the HVAC guys come in they will be impressed by the
plumbing AND the electrical work. From my military experience I have
noticed this oftten works.

I believe it. someone was asking me why I was cleaning all the brake
dust off the backsides of some cheap used wheels I bought for my
Porsche, saying that nobody was ever going to see it... I told them
that if I ever had to have someone else work on the car and they saw
clean, waxed wheels on it that they might take a little more care with
my brakes or whatever. I think it really does work.
